Edibility
Inedible

Description
Cantharellula umbonata, also known as Grayling is a small to medium-sized, funnel-shaped agaric with grey cap and forked gills that grow associated with Polytrichum moss and fruits in the summer and fall.

Cap convex at first, becoming flat to sunken; most specimens with a small, pointed umbo; margin incurved at first, becoming upturned and wavy in age; surface grey to greyish brown overall, often appearing to have whitish blotches; dry to moist; smooth to minutely hairy; flesh white; odour and taste not distinctive. Gills close to crowded, decurrent, repeatedly and regularly forked; whitish, developing spot-like reddish or sometimes yellow stains in age. Stem often with swollen portions; some-what flexible, often bent, curved, and/or twisted; white to grey; silky above, stuffed, usually with whitish mycelium binding the lower stalk to mass; often water-saturated near the base.

Chalciporus piperatus   (Peppery Bolete)
Family
Boletaceae
Location
North America, Europe
Dimensions
Cap 3-5 cm diameter, stem 4-6 cm tall * 0.3-1 cm thick
Edibility
Inedible

Description
Chalciporus piperatus, also know as Peppery Bolete, is a very small bolete that is cinnamon-brown throughout, except for the chrome-yellow stem flesh; it does not stain blue on bruising. The slightly greasy cap is convex in shape, and the stem is slender; the tubes are 0.3-1 cm long. The flesh has an intensely hot and peppery flavour, making this species inedible, although it has been used as a spice.

Cap initially convex before flattening out in age, tubes are adnate to decurrent. Pores are angular cinnamon to rust brown. Spores are susty brown.

Similar species Chalciporus piparatoides it similar but can be distinguished by the blue bruising of its cap, tubes, and pores. Chalciporus amarellus has pinker coloring and a less peppery taste.

Chlorophyllum rhacodes   (Shaggy Parasol Lepiota)
Family
Agaricaceae
Location
North America, Europe
Dimensions
Cap 5-15 cm diameter; stem 10-15 cm tall * 1-1.5 cm diameter
Edibility
Inedible

Description
Chlorophyllum rachodes, also know as Shaggy Parasol Lepiota, is smaller than the Parasol Mushroom, Macrolepiota procera, and its stem lacks the snakeskin-like patterning associated with the Parasol. It has a pale grey-brown cap and whitish gem with ring and bulbous base. It grows solitary or scattered on in woods generally, often with conifers.

Cap Initially bun-shaped, then expands and becomes convex. Only rarely do Shaggy Parasols open out completely flat. The colour is pallid buff or grey-brown, decorated with darkish brown fibrous shaggy scales. Gills white, bruising reddish, free (remote), crowded. Spore print is white. Stem whitish, tinged pinkish brown, tapering slightly upwards, base slightly bulbous. The ring is coloured as stem, spreading, double, felty, superior, movable.

Similar species include the poisonous Chlorophyllum molybdites, which has green spore print and Cholorphyllum brunneum which is also poisonous and very similar to Chlorophyllum rhacodes.

Note Many books and websites state that this is a edible mushroom, but the Shaggy Parasol has been known to cause serious illness in some people, so picking it to eat should be avoided.

Clitocybe clavipes   (Club-footed Clitocybe)
Family
Tricholomataceae

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 its 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, favouring 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.

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.
