Pezicula chiangraiensis sp. nov. from Thailand

A sexual morph of a new species, Pezicula chiangraiensis, was collected on bark of decaying wood in Chiang Rai Province, Northern Thailand. Morphologically it is closely related to P. cinnamomea but differs by its ascospores having a gelatinous sheath; in culture it produces a sporodochium-like asexual morph. Phylogenetic analysis of combined ITS, LSU, and RPB2 sequence data confirmed that P. chiangraiensis is distinct from other Pezicula spp. The new species is described, illustrated, and compared with similar taxa.
