Eurotiomycetes

Aspergillus niger

The Eurotiomycetes are a class of Ascomycota. To her include many important molds such as Aspergillus and Penicillium.

Features

Morphologically the Eurotiomycetes are very diverse. The fruit bodies ( ascomata ) are cleistothecia, perithecia or Ascostromata. Most species have asci with simple wall ( prototunicat ), which are formed in a Kleistothecium. The asci are thereby released only after the collapse of the asci and the fruiting bodies. This is considered a derived form, while the two-layer ( bitunicate ) asci are viewed with ejection mechanism in an open fruiting bodies than originally.

Today the fungi previously referred to as Plectomycetes be counted to class. The morphological characteristics are: thin, prototunicate asci; Ascomata in which the asci scattered are formed in the cavity; unicellular ascospores; Ascomata form of gymnothecisch to kleistothecisch without an ostiole ( opening); the anamorphs are highly variable and phialoblastisch and thallic hyphomycetisch.

Way of life

The Eurotiomycetes are ecologically very diverse group. The species live as Saprobionten, parasites, pathogens or as Flechtenbildner.

System

The Eurotiomycetes are a natural kinship group, a monophyletic taxon.

Eurotiomycetes to seven orders are counted that are divided into three subclasses.

A cladogram is as follows:

Chaetothyriales

Verrucariales

Pyrenulales

Onygenales

Eurotiales

Coryneliales

Mycocaliciales

Importance

Are found particularly in the subclass of Eurotiomycetidae many economically and medically important representatives: they form toxic and / or useful secondary metabolites such as antibiotics ( penicillin) or citric acid ( Aspergillus niger), are used to produce food (various molds) or by enzymes. Aspergillus nidulans is a genetic model organism.
