Pleurothecium bicoloratum & Sporidesmiopsis pluriseptata spp. nov. from Brazil

Two new species of microfungi, Pleurothecium bicoloratum and Sporidesmiopsis pluriseptata, found on decaying plant materials are described and illustrated. Pleurothecium bicoloratum, also collected in Venezuela, is distinguished by broad allantoid, bicolored, 3-septate, smooth conidia with dark olivaceous-brown central cells and hyaline ends; S. pluriseptata, thus far known only from Brazil, is characterized by obclavate, smooth, dirty brown conidia with up to 23 septa.
