Trimmatostroma commonii, a new lichenicolous hyphomycete inhabiting Graphidaceae hosts

Abstract

The new lichenicolous hyphomycete Trimmatostroma commonii is described from Réunion, the USA (Florida) and Vietnam. It strongly resembles the generic type T. salicis, from which it is distinguished by much looser conidiomatal tufts, less septate conidia and the lichenicolous habitat, growing over species of Graphidaceae in the tropics.
