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

Monilochaetes pteridophytophila differs from extant species of Monilochaetes in having darker conidiophores with fewer septae (1-4-septate). 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.
