Abstract

A new species ofStamnariais described based on morphology and molecular data from a collection made in West Siberia.Stamnariayugranais differentiated by lanceolate, strongly protruding paraphyses and comparatively narrow, fusoid-clavate ascospores. The apothecia are urn-shaped due to a prominent and even collar as inS.persoonii. The species grows on fallen side branches ofEquisetumsylvaticum, a rarely recorded host forStamnaria. The authors formally describe the new species and provide colour illustrations. In addition, the literature is reviewed on previously described species ofStamnaria. Phylogenetic reconstruction of theStamnarialineage, based on the ITS ribosomal DNA, strongly supports the three currently recognised species:S.americana,S.persooniiandS.yugrana.
