A new species of Geopyxis (Pezizales, Pyronemataceae) with ornamented ascospores from China

Zhuang, Wen-Ying; Liu, Chao-Yang


Collections of a cup-fungus from Qinghai, China represent a new species of Geopyxis with ornamented ascospores. The new species is compared with closely related fungi. To confirm its placement, relationships among a few other genera in the Pyronemataceae were investigated based on analysis of 18S nrDNA partial sequences. The new species grouped together with Geopyxis carbonaria. Both morphological and molecular data support its placement in Geopyxis. The generic concept of Geopyxis is emended to accommodate species with ornamented and guttulate ascospores.
