Tremella mesenterica is a common jelly fungus in the family Tremellaceae of the Agaricomycotina. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm (3 in) diameter, has a convoluted or lobed surface that is greasy or slimy when damp.
Amanita gemmata, commonly known as the gemmed amanita or the jonquil amanita, is an agaric mushroom of the family Amanitaceae and genus Amanita. The fruit body has a cap that is a dull to golden shade of yellow, and typically 2.5–12 centimetres in diameter. The cap surface is sticky when moist, and characterized by white warts, which are easily detached. It is initially convex, and flattens out when mature. The flesh is white and does not change colour when cut. The gills are white and closely spaced. The stem is pale yellow, and measures 4–12 cm long by 0.5–1.9 cm thick. The partial veil that covers the young fruit body turns into the ring on the stem at maturity. The spore print is white. It resembles numerous other species.
Tremella is a genus of fungi in the family Tremellaceae. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of Tremella are currently recognized worldwide. One species, Tremella fuciformis, is commercially cultivated for food.
Amanita aestivalis, commonly known as the white American star-footed amanita, is a species of fungus in the mushroom family Amanitaceae. The cap of the white fruit body is 5 to 8.5 centimetres in diameter. It sits atop a stem that is 8.5 to 16 cm long. The entire fruit body will slowly stain a reddish-brown color in response to bruising. A. aestivalis may be a synonym for A. brunnescens, and may be confused with several other white-bodied amanitas. The fungus is distributed in eastern North America.
Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.
Mycena fonticola is a species of fungus in the family Mycenaceae. First reported in 2007, it is known only from central Honshu, in Japan, where it grows on dead leaves and twigs in low-elevation forests dominated by oak trees. The fruit body of the fungus has a smooth, violet-brown cap up to 2.5 cm (1.0 in) in diameter, and a slender stem up to 10 cm (3.9 in) long. Distinguishing microscopic characteristics of the mushroom include the relatively large, distinctly amyloid spores, the smooth, spindle-shaped cheilocystidia, the absence of pleurocystidia, the diverticulate hyphae of the cap cuticle, and the absence of clamp connections.
Tuber oregonense, commonly known as the Oregon white truffle, is a species of edible truffle in the genus Tuber. Described as new to science in 2010, the North American species is found on the western coast of the United States, from northern California to southern British Columbia west of the Cascade Range. A mycorrhizal fungus, it grows in a symbiotic association with Douglas fir. It overlaps in distribution with the closely related T. gibbosum, but they have different growing seasons: T. oregonense typically appears from October through March, while T. gibbosum grows from January to June. The fruit bodies of the fungus are roughly spherical to irregular in shape, and resemble small potatoes up to 5 cm (2 in) in diameter. Inside the truffle is the gleba, which is initially white before it becomes a marbled tan color. The large, often thick-walled, and strongly ornamented spores are produced in large spherical asci. The truffle is highly prized for its taste and aroma. Some individuals have claimed success in cultivating the truffles in Christmas tree farms.
Myxarium nucleatum is a species of fungus in the family Hyaloriaceae. In the UK, it has been given the recommended English name of crystal brain. The fruit bodies are watery white, pustular or lobed, and gelatinous with small, white, mineral inclusions visible to the naked eye. It is a common, wood-rotting species in Europe, typically growing on dead attached or fallen branches of broadleaf trees. It is currently not clear whether collections from North America and elsewhere represent the same species.
Lactifluus rupestris is a species of mushroom in the family Russulaceae. Described as a new species in 2010, it is known only from the semi-arid region in the National Park of Catimbau of Brazil. The mushroom is characterized by a stout fruit body with a smooth and sticky orange cap up to 7 cm (2.8 in) in diameter. The gills on the underside of the cap are closely spaced and frequently anastomosed. The stem is 35–45 mm (1.4–1.8 in) long by 18–21 mm (0.71–0.83 in) thick. The mushrooms exude a sparse cream-colored latex when cut or injured.
Phaeotremella frondosa is a species of fungus in the family Phaeotremellaceae producing brownish, frondose, gelatinous basidiocarps. It is widespread in north temperate regions, and is parasitic on other species of fungi that grow on dead attached and recently fallen branches of broadleaf trees.
Phaeotremella foliacea is a species of fungus in the family Phaeotremellaceae. It produces brownish, frondose, gelatinous basidiocarps and is parasitic on the mycelium of Stereum sanguinolentum, a fungus that grows on dead attached and recently fallen branches of conifers. It is widespread in north temperate regions. In the UK it has the recommended English name leafy brain and has also been called jelly leaf and brown witch's butter. Prior to 2017, the name Tremella foliacea was also applied to similar-looking species on broadleaf trees, now distinguished as Phaeotremella frondosa and Phaeotremella fimbriata.
Naematelia aurantia is a species of fungus producing yellow, frondose, gelatinous basidiocarps. It is widespread in north temperate regions and is parasitic on another species of fungus that grows on dead attached and recently fallen branches of broadleaf trees. It is commonly called golden ear in North America.
Naematelia encephala is a species of fungus producing pink, brain-like, gelatinous basidiocarps. It is widespread in north temperate regions and is parasitic on another species of fungus that grows on dead attached and recently fallen branches of conifers. In the UK, its recommended English name is conifer brain.
Phaeotremella fimbriata is a species of fungus in the family Phaeotremellaceae. It produces blackish, frondose, gelatinous basidiocarps and is parasitic on the mycelium of Stereum rugosum, a fungus that grows on dead attached and recently fallen branches of broad-leaved trees. It is widespread in northern Europe. Prior to 2017, the species was generally considered a synonym of Tremella foliacea, but this latter species is restricted to conifers. Phaeotremella frondosa is a similar-looking but paler, brown species on broad-leaved trees and occurs in North America as well as Europe.
Tremella vesiculosa is a species of fungus in the family Tremellaceae. It produces light brown, lobed, gelatinous basidiocarps and is parasitic on other fungi on dead branches of broad-leaved trees. It was originally described from New Zealand.
