Abstract

A teleomorph was discovered in crosses among isolates of Leptographium yunnanense isolated from Pinus spp. originating in Thailand, China, and Japan. The ascocarps are black, globose to subglobose, and lacking necks. Ascospores are hyaline, 1-celled, surrounded by hyaline sheaths, and appear cucullate in side view, quadrangular in face view, and triangular in end view. Three species were known to have teleomorphs morphologically similar to the present fungus. However, their anamorphs were distinguishable from L. yunnanense. Thus, this teleomorph is described as Grosmannia yunnanensis.
