Monilochaetes pteridophytophila (Australiascaceae, Glomerellales), a new fungus from tree fern

Abstract

During taxonomic and phylogenetic studies of fungi on pteridophytes in Thailand, Monilochaetes pteridophytophila sp. nov. was collected from the scale of a tree fern (Alsophila costularis, Cyatheaceae). The new species is introduced based on evidence from morphological comparison and analysis of a concatenated LSU, ITS, SSU and RPB2 sequence data.Monilochaetes pteridophytophila differs from extant species of Monilochaetes in having darker and fewer, 1–4-septate conidiophores. Monilochaetes pteridophytophila forms a distinct clade basal from other species of Monilochaetes in Australiascaceae. A detailed description and illustrations of the new species are provided. We also provided a synopsis of accepted species of Monilochaetes.
