Thyridium livistonae sp. nov. from Yunnan Province, China, with two new combinations

ABSTRACT

An ascomycetous fungus was collected and isolated from dead leaves of Livistona chinensis in Lincang City, Yunnan Province, China, and morphology and multi-gene phylogenetic analyses of LSU, ITS, Actin, and β-tub were carried out to identify it. The morphology and multigene phylogeny revealed that this fungus is a distinct species of Thyridium. Therefore, this fungus is described and introduced as Thyridium livistonae sp. nov. In addition, two new combinations T. hipposidericola and T. xishuangbannaense are proposed based on morphology and phylogeny for Phialemoniopsis hipposidericola Karun., Tibpromma & X.F. Liu and P. xishuangbannaensis Karun., Tibpromma & X.F. Liu respectively. A detailed description, illustrations, and phylogenetic results are provided for the new species and two new combinations.
