Eurotiomycetidae
Aspergillus nidulans
The Eurotiomycetidae are a subclass of ascomycetes, which includes many Flechtenbildner. To her include many important molds such as Aspergillus and Penicillium.
Features
The fruit bodies ( ascomata ), if present, are kleistothecisch or gymnothecisch, spherical, are often formed in a surrounding stromal tissue and are often brightly colored. Hamathecium elements are missing. The gametangia are usually undifferentiated and consist of hyphal balls. The asci dissolve mostly, sometimes they are bitunicat. They are scattered over the fruit body, rare in a hymenium.
The vegetative forms ( Anamorphic ) are highly variable and include phialidic and arthroconidiale forms.
Way of life
The species live as Saprobionten, parasites or as mycorrhizal fungi.
System
Outer systematics
The Eurotiomycetidae are one of the two major groups in the class of Eurotiomycetes. There are also the basal group of Mycocaliciales. All three groups are monophyletic. The cladogram is as follows:
Chaetothyriomycetidae
Eurotiomycetidae
Mycocaliciales
Inside systematics
Sub- class comprises three systems, each monophyletic. The cladogram is as follows:
Coryneliales
The close relationship of the two kleistothecischen orders Onygenales and Eurotiales is undisputed. They were formerly known as Plectomyceten. The phylogenetic proximity of Coryneliales to these two orders and the classification in the Eurotiomycetidae surrendered only after DNA sequence analysis.
