The species was collected from the Mountains of Western Tien Shan and South-Western Hissar in Uzbekistan. Ophiobolus hydei is characterized by globose to subglobose ascomata with short to long papilla, cylindrical to subcylindric-clavate asci, slightly broad pseudoparaphyses, and scolecosporous, yellowish brown to brown, filiform, multi-septate ascospores that the ascospores can be separated into part spores at the septa. Multigene phylogenetic analyses using a combined gene analyses of ITS, LSU, SSU and TEF1-α indicated that the new species is closely related with Ophiobolus ponticus but differs from closely related species by its larger ascomata, asci and ascospores with split into part spores and its apparent biogeographic range as distributed in semi-arid and arid zones in Central Asia. A distribution map, morphological description and illustration, color photographs of the new species are provided} }
