Description
Tropical plants host a range of fungal niches including endophytes, pathogens, epiphytes and saprobes. A study undertaken to discover the saprobic fungal species associated with Musa sp. (banana) from northern Thailand found two hyphomycetous taxa of Spegazzinia (Didymosphaeriaceae, Pleosporales). These were collected during the dry season and their morpho-molecular taxonomic relationships were investigated. Based on phylogenetic analysis of combined SSU, LSU, ITS and TEF1-α sequence data (77% ML, 0.99 BYPP) and contrasting morphological features to the sister taxon, we introduce Spegazzinia musae as a novel species from a decaying leaf of Musa sp. Details on the taxonomy, ecology and geographical distribution of Spegazzinia species are provided. In addition, we report S. deightonii as a new host record from Musa sp. Our data further validate the taxonomic placement of Spegazzinia in Didymosphaeriaceae.
