The Trichocomaceae are a relatively large family of Ascomycota fungi . The species in the family have a pleomorphic development cycle, which means that they go through both sexual stages, called teleomorphs , and asexual stages, called anamorphs . The Trichocomaceae are particularly among the hose fungi, as many species prefer to appear in their asexual form, as anamorphs.
description
The typical fruiting bodies of the Trichocomaceae are Kleistothecia , which are embedded in a stromatic structure. However, some species also form asci without a cloister-like wall, which lie directly in the stromatic structure.
The peridium of the Kleistothecia, if any, is very variable between the individual genera. If it is a real peridium, it arises from hyphae that surround it. The asci are almost spherical or broadly club-shaped.
The species often appear as anamorphs or are even Fungi imperfecti , so that a determination on the basis of the fruiting bodies is impossible.
distribution
The family is cosmopolitan , but mainly in the tropics and subtropics .
Systematics
David Malloch divided the family into two subfamilies in 1985, the Trichocomoideae and the Dichlaenoideae . Since the same anamorphs appear in both groups, they are probably not monophyletic . However, a molecular genetic study from 1995 suggests that the Trichocomaceae family is a monophyletic group.
The following genera are included in the family:
- Subfamily Trichocomoideae
Malloch
- Byssochlamys Westling
- Dendroshaera Pat.
- Sagenoma Stolk et Orr
- Talaromyces C. Benj.
- Trichocoma Jungh.
- Subfamily Dichlaenoideae
- Chaetosartorya Subr.
- Cristaspora Fort et Guarro
- Dichlaena major. et Mont.
- Dichotomyces Scott
- Eupenicillium Ludw.
- Edyuillia Subr.
- Emericella Berk. et Br.
- Eurotium Link
- Fennellia Wiley et Simmons
- Hamigera Stolk and Samson
- Hemicarpenteles Sarbhoy et Elphick
- Hemisartorya Rao et Chowdheri
- Neopetromyces
- Neosartorya Malloch et Cain
- Penicilliopsis Solms-Laubach
- Petromyces Malloch et Cain
- Sclerocleista Subr.
- Thermoascus Miehe
- Warcupiella Subr.
The anamorphic genera Penicillium and Paecilomyces exist in the subfamily Trichocomoideae . In the subfamily Dichlaenoideae, however, the anamorphic genera Aspergillus , Penicillium , Merimbla , Paecilomyces and Polypaecilium occur.
