Abstract

14 nivicolous taxa of the genus Lamproderma collected around melting snow banks in montane areas are presented: Lamproderma acanthosporum, L. atrosporum var. atrosporum, L. atrosporum var. echinulatum, L. atrosporum var. macrosporum, L. cacographicum, L. cribrarioides, L. cristatum, L. cucumer, L. echinosporum, L. fuscatum, L. maculatum var. maculatum, L. maculatum var. macrosporum, L. ovoideum and L. pulchellum. Type material of Meylan and Meywe was studied. Detailed descriptions accompanied by photographs of sporocarps and capillitia as seen with the light microscope, and SEM micrographs of spores and spore ornamentations are given. Lamproderma atrosporum var. echinatum is synonymized with L. atrosporum var. atrosporum, L. maculatum var. macrosporum with L. maculatum var. maculatum, L. cucumer with L. ovoideum. The new variety L. atrosporum var. pseudocribrarioides is proposed.
