SVRČEK M. (1986): New or less known Discomycetes. XIV. Česká Mykologie 40(4): 203-217 (published: 7th November, 1986)
abstract
Two new genera, Calyptellopsis (typified by Hyaloscypha reticulata) and Incrupilella (typified by I. flexipila sp. nov.), are described along with ten new species of discomycetes and six new combinations. These fungi exhibit unique morphological features such as conspicuously reticulate discs or piliform hairs on apothecia, and their ecology spans from buried twigs to forest litter.
VIUNNYK V.O., LEONTYEV D.V., LÓPEZ-VILLALBA Á. (2023): First records of bryophilous myxomycetes in the lowlands of Ukraine reveal an undescribed species of Lamproderma. [18S rDNA, Bryophyta, Carpathians, Dicranum montanum, forest-steppe, hidden biodiversity, molecular barcoding.] Czech Mycology 75(2): 191-206 (published: 14th December, 2023)
abstract
Bryophilous myxomycetes are found mainly in humid mountainous regions, particularly in the Ukrainian Carpathians. Over the last three seasons, three species from this group (Colloderma oculatum, Diderma tigrinum, and Lamproderma sp.) have been discovered in Slobozhanskyi National Nature Park, a lowland region in the forest-steppe zone of north-eastern Ukraine. These finds indicate an expansion of the distribution range of bryophilous myxomycetes beyond their typical montane and boreal habitats. The unidentified species of the genus Lamproderma, related to L. muscicola, exhibits distinct morphological and molecular characteristics sufficient to consider it a separate species.
NOVOTNÝ D., LUKÁŠ J., BROŽOVÁ J., RŮŽIČKOVÁ P. (2019): Comparison of the occurrence of fungi causing postharvest diseases of apples grown in organic and integrated production systems in orchards in the Czech Republic. [Malus domestica, organic production, integrated production, Neofabraea, Penicillium.] Czech Mycology 71(1): 99-121 (published: 28th June, 2019)
abstract
During the years 2013–2015, the occurrence of fungi causing postharvest diseases of apples was evaluated in three apple orchards with integrated and organic production systems in the Czech Republic. The postharvest disease fungi were more frequently recorded in fruits from organically cultivated apple trees (average 29.97%) than those from integrated production (17.67%). This difference is statistically significant. Neofabraea, Penicillium, Alternaria and a sterile grey mycelium were the most frequently recorded taxa in apples grown in organic and integrated production systems. There were also significant differences in the frequency of occurrence of the most frequent fungal taxa between years. In 2013 and 2014, Neofabraea was the most frequently isolated genus in both cultivation systems, whereas in 2015, Penicillium was the most frequently recorded genus also in both cultivation systems, which was likely caused by the low precipitation in the 2015 growing season.
MOUBASHER A.H., ABDEL-SATER M.A., SOLIMAN Z.S.M. (2018): Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt. [fungal diversity, alkalinity, Wadi El-Natrun, lakes, Ibrahimia Canal, River Nile, molecular characterisation, ITS] Czech Mycology 70(1): 1-32 (published: 26th January, 2018)
abstract
The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi ElNatrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).
ABDEL-HAFEZ S.I.I., ABO-ELYOUSR K.A.M., ABDEL-RAHIM I.R. (2015): Leaf surface and endophytic fungi associated with onion leaves and their antagonistic activity against Alternaria porri. [phyllosphere, phylloplane, endophytes, purple blotch disease, antagonism] Czech Mycology 67(1): 1-22 (published: 10th April, 2015)
abstract
Sixty-eight fungal species belonging to 29 genera were isolated as leaf surface and endophytic fungi from healthy and purple blotch diseased onion leaves. The fungal populations associated with diseased onion leaves (1.360 × 103 CFU/g leaf in the phyllosphere, 2.614 CFU/leaf segment in the phylloplane and 1.324 CFU/leaf segment in the surface-sterilised diseased leaves) were higher than those in healthy samples (0.804 × 103 CFU in the phyllosphere, 1.184 CFU in the phylloplane, and 0.35 CFU as endophytes). Endophytic fungi of healthy leaves were represented by 12 genera and 15 species, while fungi of surface-sterilised diseased leaves included 17 species from 13 genera. The mycobiota associated with surface-sterilised diseased leaves were different from the endophytic fungi of healthy samples, whereas the disease may stimulate colonisation of opportunistic fungi causing secondary infections such as Botrytis cinerea, Penicillium aurantiogriseum, Alternaria alternata and Cladosporium spp. In contrast, healthy leaves were a source of antagonistic endophytic fungi such as Trichoderma harzianum and T. koningii. Testing the antagonistic effect of 91 fungal isolates against Alternaria porri showed that nine isolates of Trichoderma produced the highest suppressive potential (73.1%) depending on competition and mycoparasitism. Epicoccum nigrum and Penicillium oxalicum exhibited antibiosis against A. porri producing a 12 mm broad inhibition zone. In conclusion, the quantitative and qualitative compositions of fungi associated with onion leaves were distinctly influenced by A. porri infection. Mycobiota associated with asymptomatic onion leaves such as Epicoccum nigrum, Penicillium oxalicum and Trichoderma harzianum are a natural source of eco-friendly bioagents. They showed an effective antagonistic potential against A. porri, and may thus be applied as an alternative to fungicides.
ABDULLAH S.K., MONFORT E., ASENSIO L., SALINAS J., LOPEZ LLORCA L.V., JANSSON H.B. (2010): Soil mycobiota of date palm plantations in Elche, SE Spain. [soil saprotrophic fungi, phytopathogenic fungi, Phoenix dactylifera, isolation methods] Czech Mycology 61(2): 149-162 (published: 10th August, 2010)
abstract
The mycobiota of soil from date palm (Phoenix dactylifera) plantations in Elche, SE Spain was examined using 23 soil samples and five isolation methods. One hundred and nineteen species assigned to 67 genera were isolated. The most frequent species were in decreasing order: Aspergillus fumigatus, A. niger, Neosartorya spinosa, Thielaviopsis punctulata, Chaetomium bostrychodes, Gilmaniella macrospora, Aspergillus candidus, Fusarium oxysporum, Rhizopus microsporus, Sordaria fimicola, Aspergillus terreus, Chaetomium murorum, Fusarium solani, Mucor racemosus, Penicillium citrinum and Thielaviopsis paradoxa. The thermotolerant and thermophilic species of Malbranchea cinnamomea, Myriococcum thermophilum, Rhizomucor miehei, Scytalidium thermophilum, Talaromyces emersonii, Thermoascus aurantiacus and Thermomyces lanuginosus were detected in various frequencies of occurrence. Our findings are compared with those from a similar survey of soil from date palm plantations in Iraq. Our study indicates that there is no characteristic mycobiota for soil in date palm plantations except for the more frequent isolation of some species well known as pathogens on date palm.
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.

abstract
The superficialcultivation of fungus Schizophyllum commune Fr. in static liquid cultures showed production of abscisic acid - type inhibitor (ABA) and isopentyl - adenine type cytokinins (2iP) by this fungus. The analyses were done after 28 days of cultivation.
ŠIMONOVIČOVÁ A. (1992): Microfungal community structure in forest soil of North Slovakia. I. Similarity of mykocenosis (The Valley Tichá). Česká Mykologie 46(1-2): 99-105 (published: 1st April, 1993)
abstract
Microfungal community structure in four forest localities in the Valley Tichá in the High Tatra Mountains was studied. Podzolic and ranker soils are poor in organic matter, physically and chemically unfavourable. The pH values are lower – by 1.0 to 1.5 – than values in 1962, which means that the quality of the soils has degraded. These differences correspond with the quality of mycocenosis, which has also worsened. 41 species of soil micromycetes were isolated. The occurrence of the representatives of the genus Penicillium (fam. Moniliaceae) was the highest. The occurrence of the representatives of the family Mucoraceae was suppressed. The similarity of the neighbouring mycocenoses was higher than that of those more distant from each other.
NOVÁKOVÁ-ŘEPOVÁ A. (1992): The growth of soil micromycetes in the media containing herbicides Basagran, Labuctril 25 and Oxytril CM. Česká Mykologie 46(1-2): 86-92 (published: 1st April, 1993)
abstract
The changes of fungal growth in laboratory experiments (estimation of mycelial biomass and colony diameter) were studied by cultivation of 10 species of soil fungi on media with different concentrations of the herbicides Basagran, Labuctril 25 and Oxytril CM. The subject fungi responded to increased concentrations of herbicide in different ways. Cladosporium herbarum (colony diameter) and Penicillium janthinellum (mycelial biomass) were the only investigations to show a similar response to all the herbicides. Penicillium janthinellum (mycelial biomass) was the only example of a significant stimulation of fungal growth. Changes in colony pigmentation and sporulation were also recorded.

FASSATIOVÁ O. (1978): Soil micromycetes in abandoned fields in Bohemian Karst. Česká Mykologie 32(4): 226-234 (published: 1978)
abstract
An analysis of soil micromycetes in two abandoned fields in the Bohemian Karst during 1976–1977 revealed 64 species in the younger field (7 years) and 50 in the older (50 years). Dominant species in both were: Penicillium albidum, Fusarium solani, Humicola grisea, Absidia cylindrospora, and Mortierella sp. (section Polycephala). The best isolation method used nylon gauze buried in soil.

abstract
Within the framework of the 1973 Czechoslovak expedition in the Makalu Mountain region in the Himalayas (East Nepal) a total of 43 soil samples were collected for mycologic examination. Fourteen genera with 37 species of soil fungi were isolated from the samples. Though the spectrum of the isolated microscopic fungi was not wide, it contained 2 genera (Acremonium and Tolypocladium) and 15 species described for the first time amongst the Himalayan mycoflora. Some of the species were collected in the area for the second time. Among the keratinophilic microscopic fungi, Chrysosporium lucknowense was isolated. The investigation and the collection of soil samples took place at the altitudes of 1000–4900 m in the sites where the presence of terrestrial mammals was established, or direct from lair openings. The aim was to detect potentially pathogenic or keratinophilic microscopic fungi. Various species of microscopic fungi were isolated for the first time from the extreme climatic conditions of the high mountains characterized by an increased occurrence of UV radiation, great temperature fluctuations, strong air flow, a decrease in the air pressure and oxygen content and extreme abiotic and biotic factors influencing the specific existence of the organisms.

abstract
A total of 122 species of soil micromycetes were identified in 1963 in Ždánický les and the Pouzdřany steppe (South Moravia), including 25 species of Mucorales and 57 of Moniliales. Species diversity was proportional to soil temperature but not to humidity. Steppe was dominated by Aspergillus and Fusarium; forests by Chrysosporium pannorum.
