Peziza repanda, commonly known as the violet fairy cup
Description
Fruiting bodies are initially almost spherical, then cup-shaped, then expanding to being somewhat flattened in age. They do not have a stem (or at most a short, narrowed version), and may be up to 3 centimetres (1.2 in) wide by 1–1.5 cm tall, although they are often much smaller.[1] The inner spore-bearing surface of the cup, the hymenium, is pale violet to reddish violet in color, often centrally depressed and slightly wrinked. The flesh is thin (0.5–2.0 mm thick)[2] and pale purple. The exterior surface is paler than the interior, somewhat grayish, and may be pruinose near the margins—having a very fine whitish powder on the surface. The odor and taste are not distinctive.
Characteristics
P. repanda can be identified by its growth on rotted wood or wood chips, its brown upper surface (at maturity) that is usually somewhat wrinkled near the center; a whitish and minutely fuzzy under surface; a round, cuplike shape when young, and a flattened-irregular shape when mature; attachment to the wood under the center of the mushroom, rather than under the whole cup; thin, brittle flesh (rather than thick and gelatinous) and a smooth, elliptical spores that lack oil droplets.
Edibility
Like many others in the Pezizales genus, the edibility is unknown for this small and insubstantial species.[2]
Habitat and distribution
Peziza violacea is widespread on burned soil and charred wood.[1] It typically grows scattered or in groups. It is found in North America and Europe,[3] and Iceland.[4]
Similar species
The closely-related Peziza praetervisa is also violet-colored and prefers growing on burned ground. In general, Peziza praetervisa is more purple- rather than violet-colored like P. violacea. However, fruiting body color can vary depending on humidity and other factors, so they are more reliably distinguished microscopically—P. praetervisa has rough, not smooth spores with two polar oil drops. P. proteana also prefers burned ground, but is paler in color, being white or pinkish.[5]
