The occurrence of heat-resistant species of Trichophaea abundans in different types of soil in Slovakia and Czech Republic
Abstrakt
Strains of Trichophaea abundans (Ascomycota, Pezizales, Pyrenomycetaceae) were isolated from Haplic Cambisol, Haplic Cambisol (Eutric), Litic Leptosol (Sceletic), Haplic Umbrisol, and Fulvic Andosol soils in Slovakia and from Rendzic Leptosol, Chernozem, Cambisol, drilosphere, and feacal pelets of the earthworm Allolobophora hrabei collected in southern Moravia. The Slovak soils markedly differ in pH, from extremely acidic (pH(H2O) 3.9) to weakly alkaline (pH(H2O) 7.4).
T. abundans appeared as a post-burn species on Haplic Cambisol, which experienced a wildfire after a windthrow event (November 2004). In Moravia T. abundans was also isolated from sites situated in southern slopes, from time and time they affected by fires.
We also note the growth of T. abundans on the surface of Fulvic Andosol after gradual heating in the lab to temperatures reaching 105A degrees C. These findings confirmed by a review of the literature, indicate that T. abundans belongs to the group of heat-resistant fungi appearing in soils regularly influenced by the fire or grass calcining.
