Novel species of Pestalotiopsis fungi on Dracaena from Thailand.

A survey of the diversity and distribution of microfungi on Dracaena leaf litter in Songkhla Province (Thailand) yielded two collections of pestalotiopsis-like fungi. Analyses of a combined ITS, TEF1-α and TUB2 sequence data matrix were applied to infer the phylogenetic position of these new isolates in Pestalotiopsis . The phylogenies indicated that these two isolates were monophyletic and constituted a distinct lineage that perceived a taxonomic novelty in Pestalotiopsis . This clade shared a close phylogenetic affinity with P. adusta, P. krabiensis, P. pandanicola and P. papuana . The comparison of morphological features with the phylogenetically closely related taxa are given and the new species is introduced as Pestalotiopsis dracaenicola sp. nov. with comprehensive descriptions and illustrations herein.
