New species of Dictyochaetopsis and Paraceratocladium from Brazil

Abstract

Two new conidial fungi, Dictyochaetopsis brasiliensis and Paraceratocladium bacilliformis, both isolated from plant debris collected in Brazil, are described and illustrated. Dictyochaetopsis brasiliensis differs from the previously described species of the genus mainly by small, fusiform conidia with a very thin apical setula, absence of setae, and lateral, discrete conidiogenous cells with usually numerous sympodial proliferations. Paraceratocladium bacilliformis is characterized by small, bacilliform and aseptate conidia.
