The Sordariales are an order of the ashes . The majority of the species colonized wood and dung.
features
The fruit bodies are relatively large; they arise on or penetrate the surface of the substrate. The fruiting body wall consists of large cells. In some species there are paraphyses , as well as subapical globules in the asci . The ascospores are diverse and range from cylindrical, hyaline spores to ellipsoidal, brown spores, often with appendages or sheaths. In many species anamorphs are absent , where they occur, they are slightly pigmented, phialidic, Phialophora -like anamorphs. In some species the ascospores germinate directly into phialides.
Systematics
Zhang et al. were able to show for the first time in 2006 that the Sordariales are probably a monophyletic group. The following families are included in the order (with selected genera and species):
- Chaetomiaceae with 15 genera
-
Lasiosphaeriaceae with 27 genera
- Podospora and
- Cercophora are both polyphyletic.
-
Sordariaceae with 10 genera are monophyletic
- Copromyces
-
Neurospora
- Neurospora crassa , model organism for genetics.
- Sordaria
Another 20 genera are not assigned to any family at Eriksson.
