Physalidiella pentagona sp. nov. from Guizhou, China

A new species, Physalidiella pentagona, collected on dead twigs of Lindera communis in Guizhou Province, China, is described and illustrated. The fungus is mainly characterized by differentiated conidiophores with opposite or verticillate short branches and monoblastic, percurrently extending conidiogenous cells that produce solitary, smooth, quasi-stellate or T-shaped conidia with an approximately pentagonal central cell and two smaller hemispherical lateral cells. A dichotomous key to Physalidiella species is provided.
