The Trichocomaceae: Relationships with Other Ascomycetes

  • David Malloch
Part of the NATO ASI Series book series (NSSA, volume 102)


The Trichocomaceae is a relatively large family of Ascomycetes with members frequently impinging upon human activities. Because of this, they have received considerable taxonomic attention, focussed mainly on their conspicuous ana-morphs. When the holomorphs are examined closely two taxonomic groups or subfamilies become apparent: 1) the Dichlaenoideae, characterized by bivalved ascospores, frequent presence of true cleistothecial peridia, production of various anamorphs including Aspergillus, and a marked affinity for starchy or oily substrata, and 2) the Trichocomoideae, characterized by non-bivalved ascospores, lack of a true cleistothecial peridium, largely Paecilomyces and Penicillium anamorphs, and an affinity for cellulosic substrata. Most morphological features of the Trichocomaceae resemble those of Ascomycetes in other families. In spite of this, an independent terminology has developed in the Trichocomaceae that is often inconsistent with more general usage. Some recommendations are offered to resolve these differences.
