D rechsler , C harles . (USDA, Plant Industry Sta., Beltsville, Md.) A new nematode‐destroying hyphomycete of the genus Harposporium. Amer. Jour. Bot. 50(8): 839–842. Illus. 1963.—A mucedinaceous parasite that destroyed a largish nematode in a maize‐meal‐agar plate culture to which had been added some leaf mold from an oak wood in central Maryland is newly described as Harposporium dicorymbum. It permeates the host animal with colorless septate assimilative hyphae, 2.5‐8.5 μ wide, that soon put forth procumbent septate conidiophores bearing mostly subglobose phialides with 1‐3 sterigmata. Its very distinctive conidia are composed of a minutely pedicellate globose part, 4‐7 μ in diameter, together with a cylindrical outgrowth, 3‐9 μ long and 2‐3 μ wide, which is furnished distally with a short posterior and a longer anterior beak.
