DESCRIPTION

See Hyde et al. (2016).

NOTES

Hyde et al. (2016) introduced Neomicrosphaeropsis minima as a saprobic fungus isolated from dead stems of Verbascum sp. (Scrophulariaceae) in Italy. In our analyses ( Fig. 1 ), this species is related to Microsphaeropsis and transferred to this genus. SNP analysis of M. minima (W.J.Li & K.D.Hyde) M.Mehrabi-Koushki, K.D.Hyde & Jayaward. , comb. nov. with Neomicrosphaeropsis species showed a difference of 0.6% (3/521 bp) in the LSU region and 3% (13/431 bp) in the ITS.

Figures

FIG. 1. — The ML phylogenetic tree obtained from the combined LSU-ITS, tub2 and rpb2 sequence data of strains belonging to the Microsphaeropsis complex. The tree was rooted to Vacuiphoma ferulae L.W.Hou, L.Cai & Crous. Taxa retrieved or reclassified newly are shown with red dots. Bootstrap values obtained in maximum likelihood (ML) and maximum parsimony (MP) analyses ≥ 0.50% and Bayesian posterior probability values (BYPP) ≥ 0.90% are shown at the nodes, respectively. The scale bar shows the expected number of changes per site. T letter indicates type strains.
