Bifusisporella sorghi gen. et sp. nov. (Magnaporthaceae) to accommodate an endophytic fungus from Brazil

Abstract

An investigation of endophytic fungi on healthy leaves of Sorghum bicolor in Brazil led to the identification of an interesting fungus. Based on morphological features and multi-locus analyses, including ITS and LSU nrDNA, rpb1, and tef1 sequences, we propose a new genus, Bifusisporella, in the family Magnaporthaceae. The isolates exhibited a phialidic asexual morph with the following characteristics: curved conidiogenous cells, elongated, cylindrical or clavate, solitary or aggregate. Dimorphic conidia: macroconidia curved, falcate, hyaline, smooth, non-septate, guttulate, tapering at both ends; microconidia falcate, straight to slightly curved, hyaline, smooth, non-septate, hyphopodia are brown, smooth, elongated, and multi-lobulate.
