NOVOTNÝ D., ŠRŮTKA P. (2004): Ophiostoma stenoceras and O. grandicarpum (Ophiostomatales), first records in the Czech Republic.   [ophiostomatoid fungi, distribution, oak, roots, bark, Ceratocystis, Quercus petraea, Quercus robur]  Czech Mycology 56(1-2): 19-32   (published: 12th August, 2004)
  abstract   Two species of ophiostomatoid fungi were observed in oaks. Ophiostoma stenoceras was isolated during a study of endophytic mycobiota of the roots and seedlings of a sessile oak (Quercus petraea). Ophiostoma grandicarpum was recorded in the stem of a pedunculate oak (Q. robur). These fungi have not yet been reported from the Czech Republic. The knowledge on the occurrence of ophiostomatoid fungi in the Czech Republic is reviewed.

KRUPODOROVA T., BARSHTEYN V., KIZITSKA T., RATUSHNYAK V., BLUME Y. (2023): Antagonistic activity of selected macromycetes against two harmful micromycetes.   [ascomycetes, Aspergillus niger, basidiomycetes, dual-culture, Penicillium polonicum.]  Czech Mycology 75(1): 85-100   (published: 23rd June, 2023)
  abstract   Competition between 31 macromycete species and two harmful micromycetes Aspergillus niger and Penicillium polonicum was evaluated using dual-culture plate assay. All investigated fungi, except for Inonotus obliquus and Lepista luscina, possessed different levels of antagonistic activity against the tested micromycetes. Hypsizygus marmoreus and Lyophyllum shimeji were inactive against A. niger. Morchella esculenta and Oxyporus obducens were passive in the case of co-growth with P. polonicum. The study of fungal interactions showed variability in types of reactions and level of their visualisation. Co-cultivation of the studied species resulted in the following reactions: deadlock after mycelial contact and at a distance, partial or complete replacement after initial deadlock on contact. In general, the studied macromycetes showed moderate activity against the two micromycetes, as 11 species showed active and 7 species moderate antagonism. Results revealed higher antagonistic activity of macromycetes against P. polonicum than in A. niger co-cultures. Wood-decaying species Ganoderma lucidum and Trametes versicolor were the most active fungi against the two tested micromycetes with a maximal antagonism index. These findings provide valuable insights which can be further explored by means of in vivo assays to find a suitable agent for the biocontrol of diseases or spoilage caused by A. niger and P. polonicum.

KOLAŘÍK M., HULCR J., KIRKENDALL L.R. (2015): New species of Geosmithia and Graphium associated with ambrosia beetles in Costa Rica.   [ambrosia fungi, Hypocreales, Scolytodes, Cnesinus, ophiostomatoid fungi]  Czech Mycology 67(1): 29-35   (published: 10th April, 2015)
  abstract   Geosmithia cnesini sp. nov. is a dominant symbiont of the ambrosia beetle Cnesinus lecontei collected from Croton draco in Costa Rica. This fungus is characterised by whitish colonies and penicillate conidiophores with extraordinary large catenate conidia. Graphium scolytodis sp. nov. is described here from the galleries of ambrosia beetle Scolytodes unipunctatus collected from the trunk of a fallen Cecropia angustifolia tree in Costa Rica. This species does not seem to be a nutritional mutualist but rather a stable associate of unknown function. It produces mononematic conidiophores only and is related to Graphium penicillioides.

NOVOTNÝ D. (2010): First record of Ceratocystis laricicola (Ascomycota, Ceratocystidaceae) in the Czech Republic.   [Ascomycota, ophiostomatoid fungi, Larix decidua, distribution, Ips cembra]  Czech Mycology 62(1): 59-65   (published: 15th February, 2011)
  abstract   During the study of large larch bark beetle (Ips cembrae) mycobiota, the species Ceratocystis laricicola was isolated. It was detected in galleries and on the surface of the beetle body. This fungus is a well-known larch pathogen and this observation is the first report of its occurrence from the Czech Republic.

RAVIKUMAR M., SRIDHAR K.R., SIVAKUMAR T., KARAMCHAND K.S., SIVAKUMAR N., VELLAIYAN R. (2009): Diversity of filamentous fungi on coastal woody debris after tsunami on the southeast coast of India.   [tsunami, Bay of Bengal, southeast coast of India, woody litter, fungal diversity]  Czech Mycology 61(1): 107-115   (published: 29th September, 2009)
  abstract   Five coastal locations on the southeast coast of India severely disturbed after the tsunami on December 26, 2004 were surveyed for the occurrence of filamentous fungi on woody debris by means of short-term (1 month) and long-term (12 months) damp incubation. Short-term incubation revealed 26 mitosporic fungi (8 genera) ranging from 14 to 17 taxa per location with a total frequency of occurrence between 0.4 and 5.6 %. Aspergillus taxa were dominant and six of them were common to all locations.Long-term incubation yielded 35 fungi (25 genera) (22 ascomycetes, 1 basidiomycete and 12 mitosporic fungi). The total fungal taxa per location ranged from 25 to 28 with a total frequency of occurrence of 0.8 to 46.8 %. Corollospora gracilis was the most dominant ascomycete (46.8 %), while Cirrenalia tropicalis and Dictyosporium pelagicum dominated among mitosporic fungi (18 %). The total frequency of occurrence of 11 ascomycetes and four mitosporic fungi was above 10 %. Twelve ascomycetes and two mitosporic fungi were common to all locations. The richness of fungi was higher after long-term than short-term incubation. The occurrence of 61 fungal taxa in this study suggests that the tsunami-dumped woody litter on the southeast coast of India might have at least partially originated from the ocean, thus representing a mosaic of fungi existing in seawater and sediments.

JOHNOVÁ M. (2009): Diversity and ecology of selected lignicolous Ascomycetes in the Bohemian Switzerland National Park (Czech Republic).   [ascomycetes, lignicolous pyrenomycetes, biodiversity, ecology, endangered species]  Czech Mycology 61(1): 81-97   (published: 29th September, 2009)
  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.

JANKOWIAK R., ROSSA R., MIŚTA K. (2007): Survey of fungal species vectored by Ips cembrae to European larch trees in Raciborskie forests (Poland).   [ophiostomatoid fungi, Ips cembrae, Larix decidua, fungi associated with bark beetles]  Czech Mycology 59(2): 227-239   (published: 28th December, 2007)
  abstract   The species composition of fungi associated with Ips cembrae was studied in the Raciborskie forests, Poland. The fungi were isolated from overwintered adults, larvae, new adults and from galleries at various stages of development. The results showed that there was a great diversity of fungi associated with this insect. We isolated 2877 cultures, including 61 species. The most important group of fungi were ophiostomatoid species. From these, Ceratocystis laricicola, Ophiostoma brunneo-ciliatum and Graphium laricis were commonly detected, whereas eight other species occurred less frequently or sporadically. Ophiostoma ips is documented here as a new associate of I. cembrae. Ceratocystis laricicola was shown to be the primary invader occurring most frequently at early stages of brood development, particularly in the sapwood. Ophiostoma brunneo-ciliatum and G. laricis were secondary invaders following C. laricicola. In the later stages of brood development other ophiostomatoid fungi appeared.

  abstract   In 1999 and 2000, stem samples of Norway spruce (Picea abies) infested by bark beetle (Ips typographus) from one spruce stand localitya ffected by massive infestation by Ips typographus in the central part of the Šumava mountains were taken.The mycobiota of 20 adults was studied. Eighteen species of microscopic fungi were recorded. Yeasts and ophiostomatoid fungi were detected most frequently.

KUBÁTOVÁ A., KOLAŘÍK M., PRÁŠIL K., NOVOTNÝ D. (2004): Bark beetles and their galleries: well-known niches for little known fungi on the example of Geosmithia.   [microfungi, Geosmithia, Scolytidae, ophiostomatoid fungi, yeasts]  Czech Mycology 56(1-2): 1-18   (published: 12th August, 2004)
  abstract   The oak bark beetle (Scolytus intricatus, Scolytidae, Coleoptera) was studied during the years 1997-2003 with respect to the occurrence of microscopic fungi on the surface of its body. Samples were collected in eight localities in the Czech and Slovak Republics. The investigation was focused on all different stages of the beetle’s life cycle: eggs, larvae, adults be for e emergence, adults in generation and maturation feeding (nearly 600 samples), and also on galleries (400 samples). The most frequent fungi associated with S. intricatus were yeasts, Geosmithia spp. and Penicillium spp. Ophiostomatoid fungi were isolated, too. Great attention was paid to the occurrence of Geosmithia spp., which were so far recorded rarely. They were frequently found in all stages of the life cycle of Scolytus intricatus, except for males in maturation feeding. The ecology of Geosmithia spp. in feedings of phloem inhabiting insects is discussed for their negative cellulase production and the ecology of associated insect species. Trees infested with Scolytus intricatus represent a major and still little explored niche of Geosmithia spp.

NOVOTNÝ D. (2003): A comparison of two methods for the study of microscopic fungi associated with oak roots.   [Quercus robur, oakdecline, Czech Republic, mycobiota, ophiostomatoid fungi]  Czech Mycology 55(1-2): 73-82   (published: 23rd July, 2003)
  abstract   Roots of four trees with symptoms of oak decline and roots of one healthy tree of Quercus robur were examined for the presence of fungi by using two methods (moist chambe rmethod and strong surface sterilisation method). Forty-five species were isolated in this project. Significant differences in composition of mycobiota based on the used method were detected. Fusarium solani, F. proliferatum, Sphaerostilbella aureonitens, Cylindrocarpon destructans, Pénicillium simplicissimum, P. purpurogenumvar. rubrisclerotium, Trichodermaviride, Ophiostomapiceae s.l. and Pénicillium glandicola were the most frequent fungi isolated by the moist chamber method. Cryptosporiopsis radicicola, dark sterile mycelium sp. 1, Cylindrocarpon destructans, ChaetomiuM globosum, Cylindrocarpon didymum, Pénicillium simplicissimum and Trichoderma koningii were dominant species observed by the method of strong surface sterilisation.

  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.

NOVOTNÝ D. (2002): Contribution to the knowledge of the mycoflora in roots of oaks with and without tracheomycotic symptoms.   [Quercus robur, Q. petraea, Q. rubra, oak decline, ophiostomatoid fungi, Penicillium, Czech Republic, Moravia]  Czech Mycology 53(3): 211-222   (published: 10th January, 2002)
  abstract   The mycoflora of roots of three species of oak (Quercus robur, Q. petraea, Q. rubra) from two localities near Moravské Budějovice (southwest Moravia, Czech Republic) with and without tracheomycotic symptoms was studied. Fifty-seven species of fungi were identified from the samples. The most frequently isolated were Fusarium solani, Penicillium gl and icola, P. glabrum, P. simplicissimum and Acremonium curvulum. In the roots of trees with tracheomycotic symptoms two species of ophiostomatoid fungi were recorded. Abiotic condiontions (insufieciency of precipitation and higher average temperature) are considered to be primary reasons of oak decline.

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

  abstract   Part of the resting spores of E. virulenta, E. thaxteriana, and E. destruens germinate still after 72 hours of treatment with concentrated ajatin. A culture 14 days old may furnish a viable inoculum after being submerged in concentrated ajatin for 96 hours. The resting spores of all three species are at optimum state in a 14 days old culture, or during the first two months, stored at dry state in the refrigerator (7–15 °C).

  abstract   Oxidase tests were applied to 35 wood-inhabiting saprophytic Hyphomycetes to determine their ability to produce polyphenoloxidase enzymes. Most produced laccase, some tyrosinase, and a few peroxidase. The presence of these enzymes, especially tyrosinase, has taxonomic significance. This is the first report of such enzymes in Hyphomycetes.
