These collections represent new records for the country or for Europe. The following species are characterised, illustrated and discussed: Montagnula cirsii, Paradiaporthe artemisiae (first collections for the Czech Republic), Jahnula sangamonensis (first published collection for Europe) and Thyronectria pistaciae (first collection for Croatia).
HOLEC J., WILD J. (2011): Fungal diversity in sandstone gorges of the Bohemian Switzerland National Park (Czech Republic): impact of climatic inversion. [macromycetes, ecology, microclimate, boreal-montane fungi] Czech Mycology 63(2): 243-263 (published: 10th August, 2011)
abstract
The diversity of macrofungi in 8 sandstone gorges (narrow valleys bordered by sandstone walls, mostly covered by Picea forests with admixed Fagus, alt. 170–390 m) was assessed with respect to microclimatic data from 235 stations measuring temperature and soil moisture along the elevation gradient. In total, 253 species of macrofungi were found including some boreal-montane species, species preferring moist habitats and/or species of more or less natural vegetation. Microclimatically, the bottoms of gorges are significantly colder than their slopes and slope crests during the vegetation period (climatic inversion) and show higher soil moisture throughout the year. However, they are not significantly colder during the winter period and even show a higher average minimal temperature than the rest of gorges. Generally, bottoms of sandstone gorges function as „buffers“ maintaining a stable, humid and rather cold microclimate and enabling the occurrence of some boreal-montane fungi and species requiring humid conditions. Climatic inversion is a phenomenon markedly influencing the distribution of fungi in the landscape and enabling extrazonal occurrence of some species.
ADAMČÍK S., CHRISTENSEN M., HEILMANN-CLAUSEN J., WALLEYN R. (2007): Fungal diversity in the Poloniny National Park with emphasis on indicator species of conservation value of beech forests in Europe. [wood-inhabiting fungi, indicator species, beech forests, biodiversity, Slovakia, macromycetes] Czech Mycology 59(1): 67-81 (published: 28th June, 2007)
abstract
This paper lists recent finds of macrofungi from the Poloniny National Park in Slovakia. The list contains data on the occurrence of 62 taxa of macrofungi, 35 of which are new to Poloniny, and 15 have not previously been recorded from Slovakia. Additionally, 17 rare species generally considered as threatened in large parts of Europe were found. The study increases the number of fungal indicator species proposed for assessment of the conservation value of European beech forests known from selected nature reserves in Poloniny. The results of this study combined with previously published data shows that Stužica and Rožok National Nature Reserves are the sites with the highest number of these indicator species in Europe.

[Castanea sativa, chestnut blight, Czech Republic, Cryphonectria parasitica, quarantine pest] Czech Mycology 56(1-2): 45-51 (published: 12th August, 2004)
abstract
The causal agent of chestnut blight Cryphonectria parasitica (Murrill) M. E. Barr is a quarantine pest that has been recorded for the first time on the territory of the Czech Republic. Cryphonectria parasitica was observed in a sweet chestnut in the town of Uherský Brod. Infected tree was imported as a two-year-old seedling from Bratislava (Slovakia), 25 years ago. The isolate of Cryphonectria parasitica has been compatible with European vc type 13 (EU 13). Castanea sativa Mill, occurs in more than 293 localities in the Czech Republic. Its state of health was checked in 232 localities.
GHERBAWY Y.A.M.H., ABDELZAHER H.M.A. (1999): Isolation of fungi from tomato rhizosphere and evaluation of the effect of some fungicides and biological agents on the production of cellulase enzymes by Nectria haematococca and Pythium ultimum var. ultimum. [Biologicalcontrol, root-rot, fungicides Nectria haematococca, Pythium ultimum var. ultimum] Czech Mycology 51(2-3): 157-170 (published: 25th May, 1999)
abstract
Forty-five species and two species varieties belonging to twenty-six genera of fungi were isolated from 30 soil samples from the rhizosphere of tomato plants. The fungi most frequently isolated were Aspergillus flavus, A.fumigatus, A. niger, A. terreus, Gibberella fujikuroi, Nectria haematococca and Rhizopus stolonifer. Ridomil and Vitavax-captan (10, 50 and 100ppm) had no significant effects on the activity of Cl and Cₓ enzymes of Nectria haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but slightly decreased at 100ppm. Vitavax-captan (10, 50 and 100ppm) significantly decreased Cl enzyme activities of N. haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but at 100 ppm it showed a slightly inhibitory effect. Ridomil caused a slight increase in the activity of Cₓ and Cl enzymes by Pythium ultimum var. ultimum at low and moderate doses but the highest dose of Ridomil caused a slight reduction. Vitavax-captan slightly increased the activity of Cₓ and Cl enzymes in P. ultimum var. ultimum. Normal and sterilised filtrates of Myrothecium verrucaria, Penicillium oxalicum and Trichoderma harzianum induced a small decrease in Cl enzyme activity of Nectria haematococca. The sterilised filtrates of the three fungi tested caused greater inhibition compared to the normal filtrate. The production of Cₓ enzyme was slightly increased with normal and sterilised filtrates of Penicillium oxalicum and Trichoderma harzianum, but was significantly increased by both types of filtrates of Myrothecium verrucaria. The two types of filtrate of all fungi tested did not significantly affect the activity of Cl and Cₓ enzymes by lithium ultimum var. ultimum. Production of extracellular protein by Nectria haematococca was not significantly affected by any dose of the tested fungi cides. It was slightly increased by the two types of filtrate of the three tested fungi but significantly increased by the normal filtrate of Myrothecium verrucaria. The normal filtrate of all the fungi tested enhanced extracellular protein production to a greater extent than the sterilised filtrate. Extracellular proteins of Pythium ultimum var. ultimum were slightly increased by all doses of Vitavax-captan and low doses only of Ridomil, also two types of filtrate of all tested fungi caused a slightly increasing effect.
RÉBLOVÁ M. (1997): Revision and reclassification of some Chaetosphaeria species. [Ascomycetes, Chaetosphaeria, revision, taxonomy] Czech Mycology 50(2): 73-83 (published: 16th December, 1997)
abstract
Revision of the type and other herbarium material of seven species previously placed in Chaetosphaeria Tul. et C. Tul. revealed that they need to be transferred to modern genera. Two new species, Calonectria rajasthanensis sp. nov. and Eriosphaeria subtomentosa sp. nov. are described and a new combination, Pseudotrichia xanthotricha (Berk, et Broome) comb. nov. is proposed. Four synonymous names are mentioned under other species names: Chaetosphaeria patelliformis Rick is identified with Byssosphaeria rhodomphala (Berk.) Cooke and Chaetosphaeria africana Saccas, Chaetosphaeria coffeae Saccas and Chaetosphaeria rehmiana (P. Henn.) Kirschst. are identified with Melanochaeta hemipsila (Berk, et Broome) E. Mull., Harr et Sulmont.

abstract
The authors report on higher fungi of the Žofínský Virgin Forest near Nové Hrady in Southern Bohemia, the oldest forest reserve in Bohemia. Covering 97 ha at 740–830 m elevation, the forest contains mostly Fagus silvatica, Abies alba, and Picea excelsa. During two excursions, 227 species of higher fungi were collected: 131 Agaricales, 67 Aphyllophorales, 17 Discomycetes, 12 Pyrenomycetes, and 10 Myxomycetes. One new species, Collybia terginoides, and one new variety, Paxillus panuoides var. rubrosquamulosus, are described. Three species were reclassified. New species for Bohemia are marked with an asterisk.

[India, endophytic fungi, Penicillium chrysogenum, antioxidant, L-asparaginase, phenolic content.] Czech Mycology 71(2): 187-203 (published: 19th December, 2019)
abstract
This study focuses on the isolation and molecular characterisation of fungal endophytes from an ethnomedicinal plant, Rauvolfia densiflora (Apocynaceae), and an evaluation of antioxidative and L-asparaginase potentials. Fungal endophytes were isolated from leaf and stem parts of R. densiflora collected from the site of Talacauvery, Western Ghats, India. The highest colonisation frequency was found in leaves (95.5%), followed by stem parts (63.5%). A total of 19 fungal morphotypes belonging to 11 genera were identified by analysing the ITS sequences of the endophytes. The strains were screened for asparaginase production by qualitative plate assay and quantification by Nesslerisation. Maximum activity was recorded in the Penicillium chrysogenum culture (3.77 IU/ml). Submerged fermentation and ethyl acetate extraction were carried out to obtain secondary metabolites for the evaluation of total phenolic content (TPC) and antioxidative potentials. The TPC of fungal extracts ranged from 12.37 to 89.29 mg GAE/g dry extract and the IC value of scavenging activity from 26.64 to 547.23 μg/ml. The P. chrysogenum strain 50 (MH392736) was found to have the potentially highest total phenolic content and a high antioxidant capacity. This is the first report on the characterisation of fungal endophytes from R. densiflora and their antioxidative and L-asparaginase potentials.

abstract
A new combination is provided for Zythia nepenthis, a fungus repeatedly recorded on various Nepenthes plants in a greenhouse in Prague and successfully isolated from stem rot and conidial tendrils. Phenotypic data including host specificity matches the description of Z. nepenthis. Based on sequences of ITS rDNA and the gene for β-tubulin, this species was placed in Microthia, which corresponds with the generic concept of Microthia.
ABDEL-SATER M.A., MOUBASHER A.H., SOLIMAN Z.S.M. (2016): Diversity of filamentous and yeast fungi in soil of citrus and grapevine plantations in the Assiut region, Egypt. [Mycobiota, biodiversity, phenotypic and biochemical characterisation, ITS sequence, Coniochaeta canina, Aspergillus stella-maris] Czech Mycology 68(2): 183-214 (published: 20th December, 2016)
abstract
An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25 °C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species).Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9–100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1–83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3–100% on DRBC and 38.9–50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.
PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review. [biological control, postharvest diseases, microbial pesticides, rosaceous fruits] Czech Mycology 68(1): 41-66 (published: 1st February, 2016)
abstract
This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.

(2016): Fungi and lichens recorded during the Cryptogam Symposium on Natural Beech Forests, Slovakia 2011. [old-growth beech forests, diversity, conservation, indicator, red-list, Europe] Czech Mycology 68(1): 1-40 (published: 1st February, 2016)
abstract
In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchy Mts., Oblík in the Slanské vrchy Mts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.
HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi. [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution] Czech Mycology 67(2): 157-226 (published: 10th September, 2015)
abstract
Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.

abstract
Lignicolous pyrenomycetes, their anamorphs and asexually reproducing Ascomycetes were investigated on deciduous and coniferous wood at 10 localities of the Bohemian Switzerland National Park (České Švýcarsko in Czech) during 2003–2005. A total number of 109 species was recorded, 11 species were found both as teleomorph and anamorph. Individual localities were evaluated from the viewpoint of Ascomycetes diversity. Ecological demands, relationship with the type of substratum, and microhabitat preferences were noted and several ecological groups are suggested. Rare and endangered species and factors affecting Ascomycetes diversity are discussed. Several species new to the Czech Republic were recorded, viz. Apiorhynchostoma altipetum, Camarops pugillus, Crassochaeta fusispora, Lophiotrema boreale, and Togniniella acerosa.
ČERNÝ K., GREGOROVÁ B., STRNADOVÁ V., TOMŠOVSKÝ M., HOLUB V., GABRIELOVÁ Š. (2008): Phytophthora cambivora causing ink disease of sweet chestnut recorded in the Czech Republic. [Phytophthora cambivora, ink disease, Castanea sativa, sweet chestnut, Czech Republic] Czech Mycology 60(2): 265-274 (published: 27th February, 2009)
abstract
Sweet chestnut (Castanea sativa) is a non-autochthonous but commonly planted ornamental tree in the Czech Republic. However, this species is sensitive to some Phytophthora infections causing socalled ink disease. The disease usually occurs in warmer regions in Europe. In the Czech Republic it had not been detected until the nineties of the 20th century. In 1997 extensive decline of a sweet chestnut ornamental orchard with typical symptoms of ink disease was found at one locality in eastern Bohemia. Later the causal organism of this disease Phytophthora cambivora (Petri) Buisman was isolated from necrotised tissues of trunks of several declining chestnut trees. This is the first find of the pathogen causing ink disease of chestnut in the Czech Republic.

[Czech Republic, macromycetes, cultural beech and spruce forests, mycocoenology, permanent plots, ecology] Czech Mycology 56(3-4): 259-289 (published: 22nd December, 2004)
abstract
The mycoflora of cultural (artificial and managed subnatural) forests (i.e. beech, spruce and mixed forests) was studied in 18 permanent plots in the Moravskoslezské Beskydy Mts. and the adjacent part of the Vsetínské vrchy hills (Czech Republic) during they ears 1998-2000. Al together, 314 species of macromycetes were recorded. The highest number of species was recorded in plots in a young spruce forest on a former meadow (72 species ) and a waterlogged spruce forest (67 species ). Mycorrhizal fungi were the dominant group in older spruce forests (44.2 %), waterlogged spruce forests (43.3 %) and alder forest (45.6 %). A high percentage of terrestrial saprophytes was found in the young forest on a former meadow (43 %). Generally, common species prevailed.The main factor which influenced the species composition of all trophic groups was the composition of the tree layer. These results are compared with results from similar plots in the Czech Republic and neighbouring countries.

abstract
Two hundred isolates representing 31 fungal species (20 genera) were recovered from soybean roots. Samples were collected from 12 localities at 3 different growth stages of the crop. The most dominant species were Aspergillus flavus, Fusarium oxysporum, Fusarium solani (Nectria haematococca), Macrophomina phaseolina and Rhizoctonia solani. Pathogenicity tests have proved the ability of Macrophomina phaseolina and Rhizoctonia solani to infect soybean roots and produce the symptoms of damping-off and root-rot diseases.The efficacy of three antagonists (Trichodermaharzianum, Epicoccum nigrum and Paecilomyceslilacinus) as well as two organic compounds (Strom and F-760) was evaluated as to their control of pathogenic fungi . Biocontrol fungi significantly suppressed Macrophominaphaseolina and Rhizoctonia solani in vitro and in vivo. Epicoccum nigrum and Paecilomyces lilacinus suppressed the growth of the pathogens by producing an inhibition zone while Trichoderma harzianum suppressed them by overgrowing. Strom and F-760 showed lower reduction effect of diseases in comparison with the antagonists.

abstract
Complete sequences of 18S rDNA of seven strains of Tetracladium were determined. The following species were included: T. apiense, T. furcatum, T. maxilliforme, T. setigerum (one strain each) and T. marchalianum (3 strains). Sequence homology among the 7 strains was >98%. The closest published match (NCBI database) to the Telracladium sequences is one by Bulgaria inquinans (homology 95-96%). Phylogenetic analysis placed the Tetracladium complex in the vicinity of the Ascomycete orders Onygenales, Erysiphales and Leotiales.

abstract
Thirty-two species belonging to 19 genera of fungi were collected from 30 soil samples from the rhizosphere of pepper plants. The fungal colonies were characterised using classical morphological methods following identification keys. The most frequently isolated fungi were Chaetomiumglobosum, Fusarium oxysporum, Gliocladium roseum, Mucor racemosus, Myrothecium verrucaria, Penicillium aurantiogriseum, P. expansum and Trichoderma harzianum. The crude culture filtrate of Verticillium dahliae at 100% concentration caused sharp decrease in pepper seed germination. Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, and Trichoderma harzianum produced a metabolite that retarded radial growth of Verticillium dahliae.

abstract
The mycoflora of southern part of Kremnica Hills was studied by autor in 1990 and 1991. The dominant species of macromycets of beech forest stand were found out after cutting operation with the aid of frequency and occurence stability of determined fungi species. The autumn mycoaspect was characterized by occurence of these dominant fungi species: Hypoxylon fragiforme, Marasmius alliaceus, Hygrophorus ebumeus, Armiilaria ostoyae and others. The spring mycoaspect was characterized by species: Ustulina deusta, Bispora antennata, Collybia dryophila and others. The spring mycoaspect was speciesly poorer in comparison with the autumn mycoaspect in consequence of unfavourable climatic conditions. The wood-rotting fungi species have prevailed on the area. At the same time the species typical for warm-weather oak forests have been finding on the area together with the species of montane beech woods and fir-beech woods.

POUZAR Z. (1981): Notes on the taxonomy and nomenclature of the polypore Inonotus polymorphus. Česká Mykologie 35(1): 25-28 (published: 1981)
abstract
The delimitation between Inonotus nodulosus (Fr.) P. Karst. and I. polymorphus sensu Bourd. et L. Maire is discussed and the latter species is described as a new one — I. hastifer Pouz. — the original Polyporus polymorphus Rostk. being identical with I. nodulosus. On Fagus sylvatica in Central Europe in mountains a species of Inonotus is widely distributed called Inonotus polymorphus (Rostk.) Pil. sensu Bourdot et L. Maire. This species has been well characterized e.g. by Jahn (1965), Domański (1963, 1965, 1972) and Pegler (1964). Nevertheless the name used for this species is quite untenable because the original description and illustration by Rostkovius (1838, tab. 56) represents a quite different fungus, viz. Inonotus nodulosus (Fr.) P. Karst. As I found no available name for this polypore I describe it here as new even if it has been well known for a half of a century and it is quite common locally. Nevertheless the nomenclatural Code (Stafleu et al. 1978) requires such a procedure.

abstract
The importance of mixed infections of cultivated plants by viruses and pathogenic fungi is analyzed both from theoretical and practical points of view. The course of root rots caused by pathogenic fungi in various virus-infected hosts is described as an example to demonstrate these relationships. The causes of the altered disease syndrome in the root system are discussed.

abstract
The author describes an interesting collection of an operculate discomycete found in a flowerpot in The Anderson’s Museum in Cairo. In his opinion, this fungus represents a new variety: Octospora tetraspora (Fuck.) Korf var. aegyptiaca J. Moravec var. nov. A description and drawing of this new variety and notes on differences from the type variety [= Octospora tetraspora (Fuck.) Korf var. tetraspora] are provided. It differs from the typical variety by broader ascospores and longer hyphae at the margin of the excipulum.
