Deer shield

Appearance

The cap can be up to 15 cm in diameter, but is often much smaller. Initially it is bell-shaped, and often wrinkled when young. Later it expands to a convex shape. The cap can be deer-brown, but vary from light ochre-brown to dark brown, with a variable admixture of grey or black. The centre of the cap may be darker. The cap surface is smooth and matte to silky-reflective. The cap skin shows dark radial fibres when seen through a lens, indicating that the microscopic cuticle structure is filamentous. The gills are initially white, but soon show a distinctive pinkish sheen, caused by the ripening spores. The stipe is 5-12 cm long and 0.7-2.0 cm in diameter, usually thicker at the base. It is covered with brown vertical fibrils on a white ground. The flesh is soft and white. The mushroom has a mild to earthy radish smell and a mild taste at first, which may become slightly bitter.

The spore size is approximately 8×5μ, and the individual spores are elliptical and smooth. The spore print is salmon-pink to reddish-brown.

Naming

The species name, cervinus, although generally thought to refer to the colour of the cap, actually refers to antler-like protrusions on its prominent thick-walled pleurocystidia (of which there can be one to three).

Synonyms
