Trimmatostroma abietis sp. nov. (hyphomycetes) and related species.
Trimmatostroma abietis from the needles of conifers and from stone, mostly in Germany, is described. On the natural substrate it is characterized by stromatic conidiomata. Conidia are mostly two-celled, are arranged in long chains, and originate by intercalary dilatation of fertile hyphae. The wide morphological plasticity of the fungus and its physiological profile are described. Its occurrence as a saprophyte and possibly opportunistic pathogen on plants and as an invader of environments with low water activity, particularly stone surfaces, are discussed. Relationships with other taxa are outlined.
