Cysteineidomycetidae
Cysteineidomycetidae is a proposed subclass of fungi within the phylum Ascomycota. This taxonomic classification is based on molecular phylogenetic studies, particularly analyses of ribosomal DNA sequences, which suggest a distinct evolutionary lineage. The group is characterized by a unique biochemical pathway related to cysteine metabolism, though research in this area is ongoing. Fungi within this proposed subclass are diverse and include a range of ecological roles, from saprotrophic decomposition to associations with other organisms.
The taxonomic status of Cysteineidomycetidae remains under discussion and is not universally accepted by all mycological
