Xylariales
Antler -shaped wooden club ( Xylaria hypoxylon )
The wooden club -like ( Xylariales ) are an order of Ascomycota that form an own subclass Xylariomycetidae.
Features
The members of the order have a distinctly trained stroma. The fruiting bodies are dark perithecia. The asci often have an amyloid Apikalring. Occur on real paraphyses.
Way of life
Most species are Saprobionten or plant parasites in terrestrial habitats. A few representatives are sea creatures ( Anthostomella torosa ).
System
The order comprises about 800 species. To her the following families are counted ( with selected genera and species ):
- Amphisphaeriaceae with 40 genera: They resemble the Xylariaceae, but they possess ascospores without distinct germ slits. The anamorphs are Coelomyceten the genus Pestalotia
- Clypeosphaeriaceae with 10 genera: There are mostly representative with iodine -negative Ascusspitzen. The nucleation sites, if present, non-porous form.
- Corner slices Related ( Diatrypaceae ) with 9 genera: you have light brown allantoic ascospores. The anamorphs produce conidia without significant scars. The conidia are densely packed in coelomyceten conidiomata. The family is a natural kinship group. The genus delimitations are still often artificial.
- Graphostromataceae with the single genus Graphostroma
- Hypoxylon Reddish carbon Berry ( Hypoxylon fragiforme )
- Scorching fungus ( Kretzschmaria deusta )
- Antler -shaped wooden club ( Xylaria hypoxylon )
According to Zhang et al. (2006) include the following families here:
- The monotypic family Cainiaceae are residents of monocots with two-celled ascospores. The asci are amyloid Apikalringe.
- The also monotypic Myelostromataceae is usually placed in this order, the exact assignment is still uncertain.
