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 y L. pulchellum. Type material of MEYLAN and MEYER 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. echinulatum is synonymised 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.
