Some identification and differentiation data between Pluteus cervinus (cervicolor) and Pluteus salicinus:

1.Identification guide: Pluteus salicinus
Cap is smooth, convex and usually mid grey to dark greyish-brown, often with blue tints, the caps are unlined and typically 3 to 5 cm in diameter. Caps often have a darker grey central region, sometimes with a slight umbo when fully mature.The cap flesh is white and firm.White at first, becoming pale pink, the gills are broad, crowded and free.
White and untapering, typically 5 to 7mm in diameter and 4 to 7cm long, sometimes slightly bulbous at the base. The stem flesh is white and firm, and it does not become hollow as it ages. In some forms of this mushroom the stem surface bruises slightly blue-green.
Spores;Broadly ellipsoidal, smooth, 7-9 x 4.5-6µm.
Spore print; Pale pink.
Odour/taste; Not distinctive.

Habitat & Ecological role
Saprobic, solitary or in small groups on stumps, rotting fallen branches and other woody debris of broadleaf trees, particularly willow and less often alder.
Season
Fruiting from early summer to late autumn, provided the weather is mild. Most often fruiting from mid summer to mid autumn.
Similar species:

Pluteus umbrosus has a wrinkled cap and is generally a little smaller.
Pluteus cervinus has a smooth brown or fawn cap.





2.Identification guide: Pluteus cervinus

Cap is sepia to dark brown, usually with slightly darker radial streaks, caps of the Deer Shield are convex at first and then flattened; smooth, with a fibrous surface.
The cap flesh is white and firm.
White at first, becoming pale pink, the gills of Pluteus cervinus are broad, crowded and free.

The stipe or stem of this woodland fungus is white, sometimes with dark longitudinal fibres, and of even diameter or very slightly bulbous at the base. The stem flesh is white and firm, and it does not become hollow as it ages.
Spores
Ellipsoidal, smooth, 6-8 x 4-6µm.
Spore print
Pale pink.

Cystidia on the gill edges project well beyond the basidia; they are ornamented with 'horns' - see left - from which the Deer Shield gets both its common name and the specific epithet cervinus.

Odour/taste
Not distinctive.

Habitat & Ecological role
Saprobic, solitary or in small groups on stumps, rotting fallen branches and other woody debris of broad-leaf trees, this wood-rotting fungus is also found very occasionally on conifer stumps. Pluteus cervinus appears quite commonly on damp sawdust heaps along with many inedible brown toadstools.
Similar species
Pluteus umbrosus has a wrinkled cap and is generally smaller.

I go through the forests, mountains, hills, fields, and waters to understand the living world and to create a living mind.

Pluteus salicinus is a European psychedelic mushroom that grows on wood.

Pluteus salicinus fruits from April to October on stumps of willows, alder, lime, beech, poplars, maple.
