Armillaria mellea, commonly known as honey fungus, is a basidiomycete fungus in the genus Armillaria. It is a plant pathogen and part of a cryptic species complex of closely related and morphologically similar species. It causes Armillaria root rot in many plant species and produces mushrooms around the base of trees it has infected. The symptoms of infection appear in the crowns of infected trees as discoloured foliage, reduced growth, dieback of the branches and death. The mushrooms are edible but some people may be intolerant to them. This species is capable of producing light via bioluminescence in its mycelium.
Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (8 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.
Orson Knapp Miller Jr. was an American mycologist. He published numerous papers in mycology and was responsible for the naming of many taxa, as well as being one of the authors erecting the genus Chroogomphus. He described Omphalotus olivascens, several species of Amanita, and the ghoul fungus Hebeloma aminophilum.
Entoloma rhodopolium, commonly known as the wood pinkgill, is a poisonous mushroom found in Europe and Asia. In fact, it is one of the three most commonly implicated fungi in cases of mushroom poisoning in Japan. E. rhodopolium is often mistaken for edible mushroom, E. sarcopum. Symptoms are predominantly gastrointestinal in nature, though muscarine, muscaridine, and choline have been isolated as toxic agents.
Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.
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.
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.
Lactifluus deceptivus, commonly known as the deceiving milkcap, is a common species of fungus in the family Russulaceae. It is found throughout eastern North America on the ground in coniferous forests near hemlock or deciduous forests near oak, and in oak-dominated forests of Costa Rica. It produces large mushrooms with funnel-shaped caps reaching up to 25 cm (9.8 in) in diameter, on top of hard white stems that may reach 4–10 cm (1.6–3.9 in) long and up to 3 cm (1.2 in) thick. The gills are closely spaced together and yellowish-cream in color. When young, the cap is white in all parts, but the depressed center becomes dull brownish in age and breaks up into scales. The edge of the cap has a roll of cottony tissue that collapses as the cap expands. The surface of the stem—especially near the base—has a velvety texture. The mushroom "bleeds" a milky white acrid latex when it is cut or injured. Similar milk-cap species with which L. deceptivus might be confused include Lactifluus piperatus, L. pseudodeceptivus, L. caeruleitinctus, L. subvellereus, Lactarius arcuatus and Lactarius parvulus.
Lexemuel Ray Hesler was an American mycologist. He was the son of Clinton F. Hesler and Laura Iris. He obtained his B. A. degree with Wabash College in 1911 and his Ph.D. at the University of Cornell in 1914.
Entoloma politum is a species of fungus in the Entolomataceae family. It is found in Europe and North America.
Entoloma haastii is a mushroom in the Entolomataceae family. Described as new to science in 1964, it is known only from New Zealand, where it grows on the ground in leaf litter, usually near Nothofagus species.
Entoloma bloxamii, commonly known as the big blue pinkgill or Bloxam's entoloma, is a mushroom in the Entolomataceae family of fungi. It is widely distributed in Europe, although it is rare throughout its range, which also extends into Asia and North America.
Entoloma murrayi, commonly known as the yellow unicorn Entoloma or the unicorn pinkgill, is a species of fungus in the Entolomataceae family. First described from New England (USA) in 1859, the species is found in eastern North America, Central and South America, and southeast Asia, where it grows on the ground in wet coniferous and deciduous forests. The fungus produces yellow mushrooms that have a characteristic sharp umbo on the top of a conical cap. The mushroom is inedible and may be poisonous. Other similar species can be distinguished from E. murrayi by differences in color, morphology, or microscopic characteristics.
Entoloma mathinnae is a species of agaric fungus in the family Entolomataceae. Known only from Tasmania, Australia, it was described as new to science in 2009. Mushrooms have light yellow-brown, convex caps up to 8 cm (3.1 in) wide atop stems measuring 5–8.5 cm (2.0–3.3 in) long.
Pholiota iterata is a species of agaric fungus in the family Strophariaceae. Found in North America, it was first described formally by Alexander H. Smith and Lexemuel Ray Hesler in 1969.

Entoloma quadratum is a species of agaric fungus in the family Entolomataceae. The fungus was originally described as Agaricus quadratus by Miles Joseph Berkeley and Moses Ashley Curtis in 1859; Egon Horak transferred it to Entoloma in 1976. It is found in Africa, Asia, Europe, and North America.
Entoloma moongum is a South Australian species of fungus in the large agaric genus Entoloma. It was described as new to science by mycologist Cheryl Grgurinovic; the original holotype collections were made from Belair National Park in the 1930s by John Burton Cleland, who erroneously referred the fungus to Leptonia lampropus.
Entoloma decastes is a species of mushroom in the family Entolomataceae. Found in Italy, it was described as a new species in 2009. The fungus fruits in dense clusters in sandy soil, in coastal grassland. Fruitbodies have thin, dark brown caps measuring 1–5 cm (0.4–2.0 in) in diameter. The thick gills are crowded close together, and initially greyish before turning pinkish brown. Spores measure 11–14 by 9–12 µm.
