We are studying Dothideomycetes from different hosts in different geographical regions and have introduced new taxa from China, Iran and Italy. In this paper, we introduce Yunnanensis gen. nov. on Poaceae from Yunnan Province, in China, to accommodate Y. phragmitis sp. nov. Neosetophoma iranianum sp. nov. recovered from soil in Iran is also introduced and a sexual morph of Wojnowicia dactylidis on Asperula sp. (Rubiaceae) collected in Italy is also reported. DNA sequence based phylogenies (ribosomal gene) are also generated to infer potential taxonomic relationships. Yunnanensis is morphologically distinct from other genera in Phaeosphaeriaceae in having ascomata with evenly thickened walls comprising with textura angularis and textura angularis to textura prismatica inner layers, broadly cylindrical to cylindric-clavate asci, muriform ascospores with a mucilaginous sheath and a coelomycetous asexual state with muriform conidia. Phylogeny also supports Yunnanensis as a novel genus basal to Neosetophoma. Neosetophoma iranianum is distinct from other species in having subglobose, ovoid to tear-drop shaped transversely septate;, biseptate to triseptate conidia. Neosetophoma iranianum is closely related to N. lunariae but DNA sequence data differences are sufficient to segregate them as two species. Another interesting finding are the asexual/sexual morph connections in Yunnanensis phragmitis and Wojnowiciella dactylidis. All novel taxa investigated herein belong to the family Phaeosphaeriaceae.

“…Nevertheless, molecular data shows that it belongs to Sulcatisporaceae. The genus is characterized by pycnidial conidiomata, with ellipsoid, subglobose, and muriform conidia (Crous et al 2014, Tanaka et al 2015.…”

Magnicamarosporium diospyricola sp. nov. (Sulcatisporaceae) from Thailand

Phukhamsakda¹

2017

A new species of Magnicamarosporium, M. diospyricola was found on dead or dying twigs of a dicotyledonous plant in southern Thailand. The new species is distinct from other species in Sulcatisporaceae, as it has dematiaceous dictyosporous conidia. It differs from Magnicamarosporium iriomotense in its smaller conidiomata and conidia. Bayesian inference and maximum likelihood analysis of combined LSU, SSU, ITS, and TEF1-α sequence data indicate that M. diospyricola is a well-resolved species, sister to M. iriomotense, in the family Sulcatisporaceae. The morphology and phylogenetic placement of the new species are discussed in this paper.

“…The two strains of this study clustered together with the type species A. cyperi-esculenti with high phylogenetic support. Crous et al (2014) did not mention an asexual morph. Lin et al (2017) introduced a new species of Alfaria based on phylogeny and asexual morphological characteristics and provided a backbone tree.…”

“…Notes: This study is the first record of A. viridis as a saprotroph, on V. vinifera from China. This genus was introduced by Crous et al (2014) associated with leaf apical necrosis of Cyperus esculentus. In this study we describe the asexual morph of A. cyperi-esculenti and introduce a new species, A. vitis (Fig.…”

Mycosphere Notes 102–168: Saprotrophic fungi on Vitis in China, Italy, Russia and Thailand

Jayawardena¹,

et al. 2018

This is the third paper in the series, Mycosphere notes, wherein we provide notes on various fungal taxa. In this set of notes, we deal with species found on the grape genus, Vitis, one of the most important economically important crops, grown worldwide. We provide notes on 67 taxa, including two new species, Alternaria italica and Alfaria vitis, an asexual morph for Alfaria cyperiesculenti and 41 new host records or distribution records. The taxonomic placement of most taxa discussed in this study is based on a modern taxonomic framework based on analysis of multi-gene sequence data.
