Abstract

Iodosphaeria honghense sp. nov., collected from dead twigs of an unknown host in Honghe, Yunnan Province, China, is introduced based on morphological characteristics and phylogenetic analyses. Iodosphaeria honghense is distinct from other similar taxa in having cylindrical to allantoid, guttulate ascospores without a mucilaginous sheath. Maximum likelihood and Bayesian analyses based on combined LSU, ITS and RPB2 data matrix indicate that I. honghense forms a distinct lineage within the Iodosphaeriaceae. This study provides a detailed description and illustrations with morphological comparisons, and includes a key to accepted Iodosphaeria species.
