Аннотация:A new ascomycete was isolated from saline soda soils in Central Asia
(Kunkur steppe, Kulunda steppe of South Siberia, N-E Mongolia), and Africa (Kenya).
It is described as Heleococcum alkalinum sp. nov. The species produces dark brown
cleistothecial ascomata, where asci are disorganized and scattered and the ascus walls
evanesce when mature. Ascospores are bicellular, brown, thick-walled, without any
ornamentation and not constricted at the septum. The anamorph is placed in Acremonium
sect. Nectrioidea. Heleococcum alkalinum was isolated on alkaline agar (pH 10-10.5)
with carboxymethyl cellulose (CMC). It was a dominant species in samples of soda
soils with pH >10 and relatively high salinity. Its radial growth rate was almost equal
within the range of pH 6.7-10.8, demonstrating an alkali-tolerant adaptation.
