DESCRIPTION

See Hyde et al. (2016).

NOTES

Hyde et al. (2016) introduced Neomicrosphaeropsis cytisi for a saprobic fungus isolated from dead stem of Cytisus sp. (Fabaceae) in Italy. The analyses of combined LSU, ITS, tub 2 and rpb 2 sequence data for the Microsphaeropsis complex revealed that the type strain of Neomicrosphaeropsis cytisi (MFLUCC 13-0396) clustered within Microsphaeropsis lineage ( Fig. 1 ). Therefore, we transfer Neomicrosphaeropsis cytisi to Microsphaeropsis . Nucleotide comparison of Microsphaeropsis cytisi (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, 3% (13/431 bp) in the ITS and 10.5% (46/438 bp) in the rpb 2.

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.
