Three New Species of Apiospora (Amphisphaeriales, Apiosporaceae) on Indocalamus longiauritus , Adinandra glischroloma and Machilus nanmu from Hainan and Fujian, China.

Apiospora is widely distributed throughout the world, and most of its hosts are Poaceae . In this study, Arthrinium -like strains were isolated from non- Poaceae in the Hainan and Fujian provinces of China. Based on the combined DNA sequence data of the internal transcriptional spacer (ITS), partial large subunit nuclear rDNA (LSU), translation extension factor 1-α gene ( TEF1-α ) and β-tubulin ( TUB2 ), the collected Apiospora specimens were compared with known species, and three new species were identified. Based on morphological and molecular phylogenetic analyses, Apiospora adinandrae sp. nov., A. bawanglingensis sp. nov. and A. machili sp. nov. are described and illustrated.
