Phenotypic and molecular characterization of Chaetopyrena penicillata from Iran with description of a hyphomycete synanomorph

During a survey of fungi associated with Russian olive fruit rot in Northern Iran, a coelomycete fungus with setose pycnidia was isolated from symptomatic fruits. The fungus was identified as Chaetopyrena penicillata based on morphological characteristics and sequence data of ITS and LSU rDNA. A hyphomycete synanamorph, which was observed in pure cultures of this species for the first time, is described. The morphology and phylogeny of Chaetopyrena penicillata is discussed.
