Notes: Pleurotheciella fusiformis was reported from decaying submerged wood in Yunnan Province, China ( Luo et al. 2018). It is a holomorphic species characterized by semi-immersed to superficial, dark brown to black ascomata, unitunicate, cylindrical, 8-spored asci and fusiform, straight or slightly curved, hyaline, uniseptate ascospores; caespitose to loosely fasciculate conidiophores and lunate to suballantoid, 0–1-septate, hyaline conidia ( Luo et al. 2018). Phylogenetically, Pl. fusiformis is sister to Pl. aquatica ( Figure 1 ) but differs by hyaline conidiophores.

FIGURE 1. Backbone tree for Pleurotheciales generated from RAxML analyses based on a dataset of combined LSU, SSU, ITS and RPB2 sequence data. Bootstrap support values for maximum likelihood (the first value) equal to or greater than 70% and Bayesian posterior probabilities (the second value) equal to or greater than 0.95 are given above the nodes. The strain numbers are noted after the species names. Newly generated sequences are indicated in blue, new species are in red, and ex-type isolates are in bold. The tree is rooted with Conioscypha tenebrosa and C. minutispora. Strains known from freshwater habitats are marked as “ ”.
