It is proposed that the genus Lamproderma be recognized mainly on the basis that most of the capillitium arises from the apex of the columella. It is considered that the presence of a persistent peridium is too inconsistent to use as the major delimiting characteristic. Two new species are described. Their names and major characteristics are given below: Lamproderma biasperosporum, capillitium branching at the apex to form a weak, lax net, threads straight, becoming hyaline at the tips, sporangia widely scattered and less than 0.5 mm in diam, spores with clusters of larger, darker warts; Lamproderma acanthosporum, sporangia sessile, spores 18-20 μ in diam with spines reaching 2.0 μ in length. The species Lamproderma fusiforme is transferred to the genus Comatricha, and becomes C. fusiforme. Lamproderma fuscatum Meylan is regarded as a good species and is reported for the first time from the Western Hemisphere. A key to all the world species of Lamproderma is included; 18 species are recognized by the author.
