MINTER D.W. (1981): Microfungi on needles, twigs and cones of pines in Czechoslovakia.  Česká Mykologie 35(2): 90-101   (published: 1981)
  abstract   One hundred and forty-seven species of microfungi are listed from rotting needles, twigs and cones of pines in Czechoslovakia (mostly from Bohemia). Thirty-seven of these are reported as new from this region. The Czechoslovak pine mycoflora is compared briefly with those of other countries and is found more varied than any previously recorded.

GRISHKAN I., TEMINA M. (2023): Diversity of microfungal communities inside saxicolous lichens from Nahal Oren, Mount Carmel, Israel.   [endolichenic fungi, lichen thallus, melanised fungi, microclimatic contrast, rock surface.]  Czech Mycology 75(1): 15-34   (published: 28th March, 2023)   Electronic supplement
  abstract   In this study, we examined the endolichenic fungal communities of saxicolous lichens covering the rocks in the Nahal Oren valley, northern Israel. A total of 60 fungal species belonging to 35 genera were isolated from six lichen species collected in the summer and winter on the south-facing slope (SFS) and north-facing slope (NFS) of the valley. We verified that rocks serve as a possible source for the formation of endolichenic communities because communities colonising lichen thalli and the rock surface shared 39% of species and clustered together on the SFS. On the NFS, with a comparatively favourable microclimate, lichen thalli abundantly harboured typical soil fungi such as Clonostachys rosea and Fusarium spp. in winter and summer, respectively. At the same time, more severe environmental conditions on the SFS facilitated the prevalence of melanised fungi with thick-walled and multicellular spores irrespective of season. The lowest species richness and isolate densities of endolichenic communities were registered in the thalli of Collema cristatum. This decrease, especially expressed in the summer, was probably associated with the antifungal effect of substances produced by its cyanobiont, as well as with the heavy dehydration of thalli during the dry season.

NOVOTNÝ D. (2022): Contribution to the endophytic mycobiota of aerial parts of oaks.   [endophytes, Czech Republic, Quercus robur, Quercus petraea, acorns, seeds, twigs.]  Czech Mycology 74(2): 111-121   (published: 1st July, 2022)
  abstract   The endophytic mycobiota inhabiting branches of Quercus petraea from two localities in the Křivoklát area, and branches, twigs and acorns of Quercus robur from one locality near the town of Semily were studied (all sites in the Czech Republic). Seventeen fungal taxa were isolated from branches of Q. petraea. Dominant fungi were found to be Colpoma quercinum and Phoma sp. as well as sterile dark mycelium and a black yeast-like fungus close to Sarcinomyces crustaceus. Eighteen fungal taxa were found in samples of aerial parts in Quercus robur. The most frequently isolated taxa were Pezicula cinnamomea, Colpoma quercinum, Alternaria alternata agg. and Acremonium sp.

PARVEEN S., WANI A.H., BHAT M.Y., PALA S.A. (2018): Comparative study of the antimycotic activity of aqueous and ethanolic extracts of Berberis lyceum and Rumex obtusifolius against selected rot fungi.   [plant extracts, phytochemicals, antimycotic effectiveness, minimum inhibitory concentration, inhibition zone]  Czech Mycology 70(1): 47-56   (published: 16th March, 2018)
  abstract   Two medicinal plants, Berberis lyceum and Rumex obtusifolius, were screened for the presence of various phytochemicals and for their antifungal activity. The phytochemical tests carried out in the present study demonstrated the presence of phenols, alkaloids, tannins, flavonoids, quinones and terpenoids in the plant extracts. Therefore, ethanolic and aqueous extracts of these medicinal plants were evaluated for their antifungal activity against Penicillium chrysogenum, Aspergillus niger, Cladosporium herbarum and Trichothecium roseum, using the agar well diffusion method. All the plant extracts at different concentrations showed significant antifungal activity against the tested fungi. Of the two plant extracts, B. lyceum showed stronger antifungal activity than R. obtusifolius. Ethanolic extracts of both plants showed stronger mycelial growth inhibition than aqueous extracts. The ethanolic extracts of B. lyceum showed the strongest antifungal activity against Penicillium chrysogenum (inhibition zone diameter of 41 mm) followed by the ethanolic extracts of R. obtusifolius against P. chrysogenum (inhibition zone diameter 39 mm). Hence, it is concluded that these medicinal plants have a broad-spectrum antifungal activity and are a potential alternative to reduce various fungal pathogens.

HORTOVÁ B., NOVOTNÝ D. (2011): Endophytic fungi in branches of sour cherry trees: a preliminary study.   [Prunus cerasus, Czech Republic, mycobiota, endophytic fungi]  Czech Mycology 63(1): 77-82   (published: 10th August, 2011)
  abstract   Sour cherry trees (Prunus cerasus L.) harbour various fungal groups, including endophytes. Branches of two different cultivars of sour cherry trees (Újfehértoi Fürtös, Érdi Bötermö) were sampled in May and July 2010 at two study sites in the Czech Republic. Alternaria alternata and coelomycete sp. 1 were the dominant species in branches collected at one site. Aureobasidium pullulans was the most frequent fungal species in branches from the other site. Both species were dominant in May and July.

PAŽOUTOVÁ S., KOLÍNSKÁ R. (2003): Relationship of Cerebella to Epicoccum and their closest relatives among Dothideales.   [Cerebella andropogonis, Epicoccum, phylogeny, rDNA sequence]  Czech Mycology 54(3-4): 155-160   (published: 23rd May, 2003)
  abstract   The Czech isolate of Cerebella sp. was confirmed as C. and ropogonis, as its RAPD patterns were identical to those of Australian and African isolate of this species. Also, rDNA (ITS1-5.8S-ITS2) sequences of African C. and ropogonis and the Czech isolate (AJ306620 and AJ400905) were identical except for a single transition A-G at position 47 of ITS1. Comparison of these quence with databases yielded 24 closely related sequences with 96.5-98.9 % identity to Cerebella. The highest similarity was found between Cerebella and Epicoccum nigrum/ Phoma epicoccina isolates, two other related groups were : Phoma herbarum, P. medicaginis, Phomopsis sp., and P. glomerata/Ampelomyces sp.
