In this paper, we introduce this taxon as a new genus, Anthostomelloides, in the family Xylariaceae, with A. krabiensis as the type. A detailed morphological description, phylogenetic tree, photomicrographs of A. krabiensis, keys to Anthostomella-like genera, and a comparison of A. krabiensis with the morphologically similar taxa in Xylariaceae are provided. | Turkish Journal of Botany Turk J Bot (2017) 41: 107-116 © TÜBİTAK doi: Research Article Anthostomelloides krabiensis gen. et sp. nov.

Kuntze (Pandanaceae) collected in Krabi Province in Thailand. Morphological data plus phylogenetic analyses of combined ITS, LSU, RPB2, and β-tubulin sequence data clearly separate this Anthostomella-like taxon from other known genera in Xylariaceae. In this paper, we introduce this taxon as a new genus, Anthostomelloides, in the family Xylariaceae, with A. krabiensis as the type. A detailed morphological description, phylogenetic tree, photomicrographs of A. krabiensis, keys to Anthostomella-like genera, and a comparison of A. krabiensis with the morphologically similar taxa in Xylariaceae are provided.
