Global Diversity, Host Associations, and New Insights into Aigialaceae, Astrosphaeriellaceae, and Pseudoastrosphaeriellaceae.

ABSTRACT: During a survey of plant litter-associated microfungi in Guangdong and Jiangxi Provinces, China, several specimens that have carbonaceous ascomata were collected. Morphological characteristics combined with multi-gene (LSU, SSU, and tef1-α) phylogeny revealed that they belong to the Aigialaceae, Astrosphaeriellaceae, and Pseudoastrosphaeriellaceae families. Phylogenetic analyses were conducted using Maximum Likelihood (ML) and Bayesian Inference (BI) approaches. Caryospora pruni and Pseudoastrosphaeriella zingiberacearum are introduced as new species, and Astrosphaeriella bambusae, C. quercus, Fissuroma caryotae, and Neoastrosphaeriella aquatica are introduced as new host records. In addition, Caryospora minima is synonymized under
