Dermocybe [SEP] parent taxon
Dermocybe
The fungi of the Dermocybe group, commonly known as skin-heads, form a group within the huge genus "Cortinarius". They are generally considered to be a subgenus though some authorities consider them to form a genus in their own right.
They can be distinguished from other "Cortinarius" species by:
1. their brilliant colours, especially of the gills,
2. their non-hygrophanous dry cap, and
3. their dry cylindrical (non-bulbous) stem.
An
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
