An Undescribed Fungus Causing a Root Rot of Red Clover and other Leguminosae

Abstract

An undescribed fungus causing damping-off and root rot of various Leguminosae is described and placed in a new genus, Leptodiscus. The genus is distinguished by the production of small black sclerotia, the superficial, thin radiate stroma upon which the spores are borne, and by the 1-septate conidia which have one filamentous seta at each end. The species has been designated as Leptodiscus terrestris.
