Subclasses

Eurotiomycetes is a large

bitunicate in the formation of asci.[3] It contains most of the fungi previously known morphologically as "Plectomycetes".[4]

Systematics and phylogeny

Internal relationships

The class Eurotiomycetes was

monophyletic group comprising most of the fungi in "Plectomycetes", a group no longer in use that unified fungi under exclusively morphological characteristics.[4]

As more orders were added to Eurotiomycetes, the first two along with

Arachnomycetales became constrained to the first subclass, Eurotiomycetidae. In 2001, the second subclass, Chaetothyriomycetidae, was erected to accommodate Chaetothyriales and its sister group Verrucariales, as well as Pyrenulales since 2004. These two remain as the major subclasses of Eurotiomycetes.[4]

The remaining subclasses were created through more phylogenetic analyses to accommodate outlying

monotypic subclasses as of 2021:[7][8]

Eurotiomycetes

Cryptocaliciomycetidae

Coryneliomycetidae

Sclerococcomycetidae

Mycocaliciomycetidae

Lecanoromycetes

External relationships

The class Eurotiomycetes forms a clade with Lecanoromycetes, the largest lichenized class of fungi.[3]

Taxonomy

As of 2022, the taxonomy of Eurotiomycetes recognizes 5 subclasses, 10 orders, 34 families and 289 valid genera.[9] The families are listed here followed by the number of genera.

Nomenclature

The

teleomorph
(sexual form) names used in reference to them.

Morphology

Many members (Eurotiales, Onygenales) produce an enclosed structure

cleistothecium
within which they produce their spores.
