Abstract

During a survey of fungal diversity of plant litter in China, numerous isolates with affinity to Pleosporales (Dothideomycetes, Ascomycota) were recovered. Morphology, coupled with phylogenetic analyses using Maximum Likelihood and Bayesian Inference on combined LSU, SSU, ITS, tub2, and tef1-α sequence data, revealed that these isolates belong to the families Acrocalymmaceae and Didymosphaeriaceae, and are introduced as Acrocalymma poaceicolasp. nov. and Neptunomyces chinensissp. nov. In addition, five new host records, A. ampeli, Neokalmusia arundinis, Paraconiothyrium archidendri, Pseudopithomyces chartarum, and Spegazzinia deightonii are reported from litter of Livistona chinensis, Sporobolus alterniflorus, Citrus maxima, Hedychium coronarium, and Arundo pliniana, respectively. All the new species and host records were compared with phylogenetically and morphologically closely related species, and detailed descriptions, micrographs, and phylogenetic analysis results are provided.
