abstract
A set of cultures of wood-degrading Basidiomycetes was screened for the ability to decolorize model synthetic dyes with the aim of selecting strains with the highest activities of ligninolytic enzymes. Four decolorization patterns were observed; some species possessed no decolorizing ability, some decolorized on all the media, some decolorized only when fully grown, and only apart of them followed a typical behaviour described in Phanerochaete chrysosporium Burds., i.e. decolorized only on nutrient limited media. The strains with the highest decolorizing capabilities will be further studied with respect to biodegradation of aromatic organopollutants.

abstract
Chronic Candida tonsillitides (caused always by Candida albicans) appeared in our group in 3% of examined children. The clinical picture was polymorphous: sometimes slight furs were observed on the tonsils, sometimes C. albicans was found in the crypts, often without plugs and conspicuous symptoms. Tonsillectomy was considered the most suitable therapeutic solution. Diagnosis could not be made without mycological examination including quantitative and qualitative assessment of the germs. Control was carried out by lingual smears. Yeasts were found in 54.7% of children, C. albicans in 42.7%.
CUDLÍN P., MEJSTŘÍK V., ŠAŠEK V. (1980): The effect of the fungicide Dithane M-45 and the herbicide Gramoxone on the growth of mycorrhizal fungi in vitro. Česká Mykologie 34(4): 191-198 (published: 1980)
abstract
The minimum inhibiting concentration of the fungicide Dithane M-45 and the herbicide Gramoxone was determined in pure cultures of 13 species of fungi forming mycorrhizae with Pinus sylvestris L., grown under submerged conditions (reciprocal shaker). According to their pesticide sensibility the fungal species were divided into five groups. Gramoxone showed a less intensive inhibition than Dithane M-45.

PRÁŠIL K., ŠAŠEK V. (1977): Antibiotic activity of some Pyrenomycetes. Česká Mykologie 31(1): 1-7 (published: 1st March, 1977)
abstract
A set of cultures of stromatic lignicolous Pyrenomycetes was screened for antibiotic activity. From a total of 25 species (36 strains), the antibiotic activity was detected in 9 species. The most active species were Diaporthe impulsa, D. pustulata, Hypoxylon multiforme, Hypoxylon sp. and Valseutypella tristicha. However, the antibiotic activity lowered down in the course of re-inoculation, especially when the cultures were transferred into the submerged conditions. According to this finding, more appropriate test would be the direct screening of the submerged cultures.

MUSÍLKOVÁ M., MUSÍLEK V., ŠAŠEK V. (1975): Release of yeast spheroplasts by an enzyme complex from Lycoperdon perlatum Pers. ex Pers. Česká Mykologie 29(3): 153-156 (published: 1975)
abstract
Fruit bodies of some Basidiomycetes, e.g. Lycoperdon periatum, contain enzymes capable of destroying cell walls of yeasts and filamentous fungi, thereby releasing spheroplasts. A lyophilized enzyme preparation from L. periatum remained active over long storage in cold. The study elaborates on the potential of lytic enzyme complexes from higher fungi for degrading the cell walls of viable yeast cells.

abstract
Eleven species of Diaporthaceae (order Diaporthales) were studied in pure culture. The development of their morphology and the influence of temperature on their growth were examined. Conidial stages were obtained for 10 species, six of them for the first time in culture. The importance of cultural studies for the taxonomy of this group of Pyrenomycetes is discussed.
PRÁŠIL K., ŠAŠEK V., URBAN Z. (1973): Isolation and cultivation of some stromatic lignicolous Pyrenomycetes. I. Xylariales. Česká Mykologie 27(3): 133-150 (published: 1973)
abstract
Twelve species of the order Xylariales were studied in pure culture. Their morphology during growth and the effect of temperature on growth rates were observed. Conidial stages were recorded in ten species, three of them for the first time in culture. The study emphasizes the usefulness of culture studies in clarifying life cycles and taxonomy of stromatic Pyrenomycetes.
ŠAŠEK V., MUSÍLEK V. (1968): Antibiotic activity of mycorrhizal Basidiomycetes and their relation to thehost-plant parasites. Česká Mykologie 22(1): 50-55 (published: 1968)
abstract
35 strains (17 species) of mycorrhizal Basidiomycetes were cultured with Pinus silvestris seedlings. The fungi showed only slight antibiotic activity, which did not increase with seedling presence. In 12% of tests, growth of parasitic fungi was inhibited. Rhizoctonia solani was the most inhibited species.
ŠAŠEK V. (1967): Meeting with Soviet mycologists. Česká Mykologie 21(4): 201-204 (published: 20th October, 1967)
abstract
Meeting with Soviet mycologists. The article discusses the activities and institutions of Soviet mycologists as observed during a two-month stay in Moscow, Kyiv, and Leningrad. It describes challenges due to lack of a unified mycological society and absence of dedicated journals. Special mention is given to Dr. N. M. Šemachanova and her work on mycorrhiza at the Microbiological Institute of the Academy of Sciences of the USSR, and to Dr. L. A. Beljakova for her work on fungal culture preservation.
