PRÁŠIL K., ŠAŠEK V., URBAN Z. (1974): Isolation and cultivation of some stromatic lignicolous Pyrenomycetes. II. Diaporthales. Česká Mykologie 28(1): 1-18 (published: 5th February, 1974)
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.
PODLAHOVÁ R. (1972): A contribution to the knowledge of Pyrenomycetes of the Lubietovský Vepor near the town Banská Bystrica (Central Slovakia). Česká Mykologie 26(1): 43-57 (published: 1972)
abstract
The author describes 28 species of Pyrenomycetes collected in the neighbourhood of the mountain Lubietovský Vepor near Banská Bystrica in Slovakia. Five species have not been previously found in ČSSR: Gnomonia depressula Karst., Massaria stipitata Fuck., Mycosphaerella jutlandica Munk, Pseudomassaria sepincolaeformis (Sacc.) v. Arx, Valsa ribesia Karst. The descriptions, comments and figures are prepared from these collections, which have been preserved as exsiccati in the Mycological Herbarium of the National Museum in Prague.
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.
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.
