The Chaetothyriomycetidae are a subclass of sac fungi that includes many lichens .
features
The most important morphological features are perithecia as fruiting bodies, and asci with two wall layers (bitunicat), the opening of which ranges from tearing to shrinking.
The fruiting bodies are formed on the surface of or sunk into the thallus . The thallus often grows on the surface of rocks, lichen, rotting plant matter, or other substrate. The ascospores are variable, from colorless to pigmented. The hemathecium , if present, consists of pseudoparaphyses . The pigments are similar to melanin .
The asexual forms ( anamorphic ) are phialidic or annellidic and occur only in the non-lichen formers.
Way of life
The species are often lichens formers . There are also parasites and saprobionts .
Systematics
External system
The Chaetothyriomycetidae are one of the two large groups in the class of Eurotiomycetes. There is also the basal group of Mycocaliciales . All three groups are monophyletic . The cladogram looks like this:
