Peziza violacea, commonly known as the violet fairy cup or the violet cup fungus, [1] is a species of fungus in the genus Peziza of the family Pezizaceae. As both it common names and specific epithet suggest, the cup-shaped fruiting bodies are violet colored on the interior surface. P. violacea is typically found growing on burnt soil.

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. [2] The inner spore-bearing surface of the cup, the hymenium, is pale violet to reddish violet in color, often centrally depressed and slightly wrinkled. The flesh is thin (0.5–2.0 mm thick) [3] 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.

Microscopic characteristics

The spores are elliptical, smooth, hyaline, without any oil droplets (eguttulate), with dimensions of 16–17 × 8–10  μm. [2] The asci are roughly cylindrical, 8-spored 200–250 × 12–15 μm. [4] The paraphyses are club-shaped, filled with violet granules, and have curved tips; they are up to 8 μm wide. [4]

Edibility

The species is considered inedible. [5]

Habitat and distribution

Peziza violacea is widespread on burned soil and charred wood. [2] It typically grows scattered or in groups. It is found in North America and Europe, [4] and Iceland. [6]

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. [1]

Pezizaceae Family of fungi

The Pezizaceae are a family of fungi in the Ascomycota which produce mushrooms that tends to grow in the shape of a "cup". Spores are formed on the inner surface of the fruit body (mushroom). The cup shape typically serves to focus raindrops into splashing spores out of the cup. Additionally, the curvature enables wind currents to blow the spores out in a different manner than in most agarics and boletes.

<i>Sarcoscypha coccinea</i> Species of fungus in the family Sarcoscypha found in Africa, Asia, Europe, North and South America, and Australia.

Sarcoscypha coccinea, commonly known as the scarlet elf cup, scarlet elf cap, or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales. The fungus, widely distributed in the Northern Hemisphere, has been found in Africa, Asia, Europe, North and South America, and Australia. The type species of the genus Sarcoscypha, S. coccinea has been known by many names since its first appearance in the scientific literature in 1772. Phylogenetic analysis shows the species to be most closely related to other Sarcoscypha species that contain numerous small oil droplets in their spores, such as the North Atlantic island species S. macaronesica. Due to similar physical appearances and sometimes overlapping distributions, S. coccinea has often been confused with S. occidentalis, S. austriaca, and S. dudleyi.

Humaria hemisphaerica, commonly known as the hairy fairy cup or the brown-haired fairy cup, is a species of fungi in the family Pyronemataceae. This mycorrhizal fungus is recognized by its white inner surface and hairy brown outer surface. The specific epithet is derived from the Latin word hemisphaericum, meaning half a sphere.

<i>Geopyxis carbonaria</i> Species of fungus

Geopyxis carbonaria is a species of fungus in the genus Geopyxis, family Pyronemataceae. First described to science in 1805, and given its current name in 1889, the species is commonly known as the charcoal loving elf-cup, dwarf acorn cup, stalked bonfire cup, or pixie cup. The small, goblet-shaped fruitbodies of the fungus are reddish-brown with a whitish fringe and measure up to 2 cm (0.8 in) across. They have a short, tapered stalk. Fruitbodies are commonly found on soil where brush has recently been burned, sometimes in great numbers. The fungus is distributed throughout many temperate regions of the Northern Hemisphere. It is found in Europe, Turkey, and North America. Although it is primarily a saprotrophic species, feeding on the decomposing organic matter remaining after a fire, it also forms biotrophic associations with the roots of Norway spruce.

<i>Peziza praetervisa</i> Species of fungus

Peziza praetervisa, commonly known as the purple fairy cup or the fireplace cup, is a species of fungus in the genus Peziza, family Pezizaceae. Recognized by its flattened, purple, cup-like fruitbodies, this widespread fungus typically grows scattered or in clusters on burnt ground.

<i>Scutellinia scutellata</i> Species of fungus

Scutellinia scutellata, commonly known as the eyelash cup, the Molly eye-winker, the scarlet elf cap, the eyelash fungus or the eyelash pixie cup, is a small saprophytic fungus of the genus Scutellinia. It is the type species of Scutellinia, as well as being the most common and widespread. The fruiting bodies are small red cups with distinct long, dark hairs or "eyelashes". These eyelashes are the most distinctive feature and are easily visible with a magnifying glass. The species is common in North America and Europe, and has been recorded on every continent. S. scutellata is found on rotting wood and in other damp habitats, typically growing in small groups, sometimes forming clusters. It is sometimes described as inedible, but its small size means it is not suitable for culinary use. Despite this, it is popular among mushroom hunters due to its unusual "eyelash" hairs, making it memorable and easy to identify.

<i>Caloscypha</i> Genus of fungi

Caloscypha is a fungal genus in the family Caloscyphaceae. A monotypic genus, it contains the single species Caloscypha fulgens, commonly known as the spring orange peel fungus, the golden cup, or the dazzling cup. It is a cup fungus, typically up to 4 centimetres (1.6 in) in diameter, with a bright to pale orange interior and orange; specimens that are old or bruised often have an olive-green discoloration, especially around the edges. In North America, it is usually found on the ground in forest litter near conifers. Fruiting occurs in early spring following snow melt. The asexual (imperfect), or conidial stage of C. fulgens is the plant pathogenic species Geniculodendron pyriforme, known to infect dormant seeds of the Sitka spruce.

Tylopilus plumbeoviolaceus, commonly known as the violet-grey bolete, is a fungus of the bolete family. First described in 1936, the mushroom has a disjunct distribution, and is distributed in eastern North America and Korea. The fruit bodies of the fungus are violet when young, but fade into a chocolate brown color when mature. They are solid and relatively large—cap diameter up to 15 cm (5.9 in), with a white pore surface that later turns pink, and a white mycelium at the base of the stem. The mushroom is inedible. A number of natural products have been identified from the fruit bodies, including unique chemical derivatives of ergosterol, a fungal sterol.

<i>Lactarius subflammeus</i> Species of fungus

Lactarius subflammeus, commonly known as the orange milk cap, is a species of fungus in the family Russulaceae. It is found in western North America in the late summer and fall and is especially common in the Pacific Northwest, where it grows on the ground near conifers like pine and spruce. The brightly colored fruit bodies, which are slimy or sticky, have scarlet caps when young that soon fade to brilliant orange. The stem—typically longer than the width of the cap—is also bright orange but the gills are whitish. The mushroom secretes a whitish latex when it is cut or injured.

<i>Lactarius alnicola</i> Species of fungus

Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the family Russulaceae. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm (7.9 in) wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to 5 cm (2.0 in) long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. pitkinensis, known from Colorado, and var. pungens, from Michigan.
