Pluteus roseipes Höhn

Phylum: Basidiomycota - Class: Agaricomycetes - Order: Agaricales - Family: Pluteaceae

Pluteus roseipes, southrn England

The velvetty cap and rose-flushed slightly velvetty stem of this medium-sized shield mushroom are its most distinctive macroscopic features; however, its scarcity and its preference for shaded woodland sites make it an all too infrequent find.

Distribution

A very rare find in Britain, this wood-rotting mushroom is a rare to occasional find in parts of mainland Europe from ScandinaviaI down to the Mediterranean and northern Spain.

Taxonomic history

This woodland mushroom was described in 1902 by Austrian mycologist Franz Xaver Rudolf von Höhnel (1852 - 1920) who gave it the binomial scientific name Pluteus roseipes by which it is known to this day.

As far as I can determine, Pluteus roseipes has just one synonym of: Pluteus leoninus var. roseipes (Höhn.) E. Ludw.

Etymology

Pluteus, the genus name, comes from Latin and literally means a protective fence or screen - a shield for example! The specific epithet roseipes simply means 'with a reddish stem'.

Stem of Pluteus roseipes

Stem

5 to 8cm long and 3 to 10mm diameter, cylindrical often wider at the base; longitudinally fibrillose and faintly flocculose/velvetty; whitish background flushed with pink; no stem ring.

Odour/taste

Not distinctive or smelling and tasting faintly fruity or, as some say, of radish!

Habitat & Ecological role

In common with other shield mushrooms, this is a wood-rotting (saprobic) fungus that favours very well rotted timber, most often buried in leaf litter. It is most often found in woodlands on alkaline soil.

Season

Fruiting from mid summer to late autumn.

Similar species

Pluteus cervinus is usually larger and has a smooth brown or fawn cap.

Pluteus leoninus is very similar except for its colours! (These two species are closely related.)

Culinary Notes

Pluteus roseipes is not generally considered to be an edible species, and in view of its rarity this mushroom should not be gathered for eating.
