JANEČKOVÁ V., FASSATIOVÁ O., DANIEL M., KŘIVANEC K. (1977): Findings of soil microscopic fungi in the Himalaya Mountains (Nepal). Česká Mykologie 31(4): 206-213 (published: 1977)
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.
KŘIVANEC K., JANEČKOVÁ V., OTČENÁŠEK M. (1977): Arthroderma melis spec. nov. - a new dermatophyte species isolated from badger burrows in Czechoslovakia. Česká Mykologie 31(2): 91-99 (published: 1977)
abstract
A new species of the dermatophyte Arthroderma melis was isolated from the burrows of badgers (Meles meles) and described. The small cleistothecia of the perfect state of the fungus are characterized by asymmetric dumb-bell-shaped cells of the peridial hyphae. The imperfect state is distinguished by pink colonies consisting of hyphae with multiple sessile microconidia and single 3–4-celled macroconidia of the Trichophyton type. Intermedial forms of conidia, mostly two-celled, are also typical of the microscopic pattern. The newly described species is not pathogenic for guinea pigs and white mice and is unable to grow at 37°C. It is systematically classified into the A. curreyi group.
