Clitocybe clavipes   (Club-footed Clitocybe)
Family
Thricholomataceae
Location
North America, Europe
Dimensions
Cap 4-8 cm diameter, stem 3-7 cm tall * 1-1.5 cm thick
Edibility
Inedible

Description
Clitocybe clavipes, commonly known as the club-foot or club-footed clitocybe is identified by it's club-shaped stem, which is swollen at the base and tapering toward the top and funnel-shaped cap with white girls that extend downward. It grows solitary or in small troops on soil in broad-leaf woods, favorfavoring beech.

Cap convex with a small boss, becoming plane to depressed in shape. It has a smooth surface. Cap colours are generally grey-brown, sometimes tinged olive, with a pale margin. Gills are strongly decurrent and cream-yellow in colour, contrasting with the rest of the mushroom. There are some smaller gills in between the regular gills, and the gills are occasionally forked near the stem. The gill edges are straight in younger mushrooms and sometimes wavy (undulate) in older ones. Flesh white, but slightly yellow at the base. Stem bulbous base, its surface is covered in silky fibres, and it is the same colour as the cap.

Synonyms the newer name for Clitocybe clavipes is Ampulloclitocybe clavipes.

Family
Tricholomataceae
Location
North America, Europe
Dimensions
Cap 2-6 cm diameter, stem 2-6 cm tall * 0.2-0.5 cm diameter
Edibility
Inedible

Description
Collybia dryophila, also known as Gymnopus dryophilus, is a smallish agaric has a pale tan cap, whitish gills, and a flushed tan stem. The mushroom occurs in troops or more or less tufted on soil and scattered leaves under leafy and coniferous trees.

Cap convex, and russet to ochre. Gills only thinly attached to the stem, whitish and crowded. Spores are white. Stem more or less similarly colored as the cap, more or less equal but slightly bulbous at base. The mushroom has no ring.

Similar species Collybia aquosa has pale pink rhizoids and Collybia ocior has a rather dark cap and pale yellow gills.

Synonyms the mushroom is now known under the name Gymnopus dryophilus.

Coltricia perennis   (Tiger's Eye)
Family
Hymenochaetaceae
Location
North America, Europe
Dimensions
Cap 2-8 cm diameter, stem 0.2-1 cm thick * 1.3-3.5 cm tall
Edibility
Inedible

Description
Coltricia perennis, also known as Tiger's Eye, is an annual polypore that is very unusual in that it grows in the soil rather than on dead wood. It prefers humus-rich sandy soil on woodland edges and on acidic heathland.

Fruiting body upper surface zoned concentrically in shades of ochre, grey and rust with maroon tinge, disc-like, at first finely downy, becoming smooth with age; stem rusty-brown, downy, more or less central. Flesh brown, thin, corky, harder when dry.

Similar species Several tooth-fungi are similar above but have spiny undersides.

Coprinus plicatilis   (Umbrella Inky Cap)
Family
Coprinaceae
Location
North America, Europe
Dimensions
Cap 0.8–2 cm; stem 4-8 cm tall * 1-2 mm diameter
Edibility
Inedible

Description
Parasola plicatilis, also known as Parasola plicatilis or Umbrella inky cap is a small parasol-like agaric that can be found in grassy areas, alone, scattered or in small groups. The fruiting bodies grow at night after rain, and will self decompose after spore dispersion is achieved.

Cap buff, more cinnamon at the centre and later with gray tinge at the margin. The shape is ovoid at first, becoming convex or bell-shaped, then flat and finally shallowly convex like a parasol. Gills pallid clay, soon grey and finally black; free from the stem; close or nearly distant. Stem white or buff, equal above a slightly swollen base; fragile; hollow; bald or very finely silky. The mushroom has no ring.

Similar species Coprinus auricomus tends to be a bit bigger and has browner cap. A microscope reveals thick-walled brown hairs, confirming it's identity. Other similar species include Coprinus keuhneri, Coprinus leiocephalus and Coprinus nudiceps. They can be distinguished only by carefully measuring the spores.

Cortinarius alboviolaceus   (Silvery Violet Cort)
Family
Cortinariaceae
Location
North America, Europe
Dimensions
Cap 5-8 cm diameter, stem 5-12 cm tall * 1-2 cm thick
Edibility
Inedible

Description
Cortinarius alboviolaceus, also called Silvery violet cort, has a convex to umbonate, fleshy, silvery violet cap. It grows with deciduous trees, but also found with conifers, often on acidic soil.

Cap at first domed and then shallowly convex with a broad umbo, the dry, silky caps vary in colour from almost white through pale lilac to pale mauve. The rather broad, sinuate, notched gills are medium spaced and light gray-blue to cinnamon-brown. Stem The twisted, often club-shaped stem is often bowed rather than straight, is pale and fibrous with a slightly clavate (club-shaped) base and sometimes marked rust-brown around the veil zone by deposited spores.

Similar species Cortinarius malachius has a slightly scaly cap. It is associated with conifers, as are Cortinarius camphoratus and Cortinarius tranganus, which are noted for their penetrating smells; the former reminiscent of half-rotten potatoes, the latter sweet and sticky.
