Abstract

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.

摘要

描述了从针叶树针叶和石头上分离得到的冷杉微座孢，主要分布在德国。在自然基质上，它的特征是具有基质分生孢子盘。分生孢子大多为双细胞，排列成长链，由可育菌丝的居间膨大产生。描述了该真菌广泛的形态可塑性及其生理特征。讨论了它作为植物上的腐生菌和可能的机会性病原菌的存在情况，以及作为低水分活性环境（特别是石头表面）的入侵者的情况。概述了与其他分类单元的关系。
