Reexamination of six taxa described inLeptosphaeriafrom species in the Ranunculaceae

Abstract

Six fungal species previously placed in Leptosphaeria and originally described on plant species in the Ranunculaceae were reevaluated for their proper taxonomic position and redescribed and illustrated from the type and authentic materials. The original position of Leptosphaeria nigromaculata as Ophiobolus nigromaculata is confirmed. Metasphaeria rupicola is transferred to Massarina, and a lectotype is designated. Leptosphaeria scotophila and Leptosphaeria thorae are transferred to Phaeosphaeria, and a lectotype is designated for L. scotophila. The previous transfer of Leptosphaeria anthostomoides to Montagnula anthostomoides is confirmed. The new genus Barrella is established and typified by Leptosphaeria thalictri, and a neotype is designated. Key words: systematics, Loculoascomycetes, Leptosphaeria.
