is 4 to 8 cm (1.6 to 3.1 in) broad, deep violet at first and then becomes violet-brown with age, convex, glutinous, and smooth. The flesh is thick and tinted lavender
. The gills are brown and tinted lilac-violet. The stipe
is 6 to 8 cm (2.4 to 3.1 in) long, cylindrical, often swollen at the base, pale lilac above the cortina
and deep violet below it. The spores are brown and fruit bodies
will produce a brown spore print
. The species has no odor. When C. archeri is young, they have a cortina, but it is flimsy and tears apart as the cap expands which is why there are few traces of it on fully mature specimens.

Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...

The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp that supports a spore-bearing surface, the hymenium. The hymenium may consist of lamellae, tubes, or teeth, on the underside of the pileus...

Basidiocarp
In fungi, a basidiocarp, basidiome or basidioma , is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures...

Habitat
The species is common in eucalyptEucalypt
Eucalypts are woody plants belonging to three closely related genera:Eucalyptus, Corymbia and Angophora.In 1995 new evidence, largely genetic, indicated that some prominent Eucalyptus species were actually more closely related to Angophora than to the other eucalypts; they were split off into the...
