Psilocybe is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Most or nearly all species contain the psychedelic compounds Psilocybin, psilocin and baeocystin.
Psilocybe mexicana is a psychedelic mushroom. Its first known usage was by the natives of North and Central America over 2,000 years ago. Known to the Aztecs as teotlnanácatl, from the Nahuatl teotl ("god") + nanácatl ("fungus"). This species was categorized by French botanist Roger Heim.
Bruno Bernard Heim was the Vatican's first Apostolic Nuncio to Britain and was one of the most prominent armorists of twentieth century ecclesiastical heraldry. He published five books on heraldry and was responsible for designing the coats of arms of four popes. He was also Grand Prior of the Sacred Military Constantinian Order of Saint George.
Camarophyllopsis is a genus of 26 species of fungi with a widespread distribution, especially in northern temperate areas. Members of Camarophyllopsis are distinguished from members of the family Hygrophoraceae mainly by their hymenoderm pileipellis. The arrangement of lamellar trama is highly variable between species. Coloration of the fruit body is dull, tending toward browns and grays. Many members of this genus were formerly classified in the genus Hygrotrama, but the two genera were subsequently put in synonymy.
Conocybe is a genus of mushrooms with Conocybe tenera as the type species and at least 243 other species. There are at least 50 different species in North America.
Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.
Armillaria heimii is a species of fungus in the family Physalacriaceae that is found in East Africa. It causes root rot in tea trees. The fungus was originally described as Clitocybe elegans by Roger Heim in 1963. David Pegler transferred it to the genus Armillaria in 1977.
Souffelweyersheim is a commune in the Bas-Rhin department, Alsace, Grand Est, northeastern France, and is part of metropolitan Strasbourg.
Termitomyces is a genus of basidiomycete fungi belonging to the family Lyophyllaceae. There are 30-40 species in the genus, all of which are completely dependent on termites to survive. They are the food source for a subfamily of termites, the Macrotermitinae, who enjoy an obligate symbiosis with the genus similar to that between Atta ants and Attamyces mushrooms. Despite this relationship, spore transfer is still accomplished mainly by shedding from mushrooms, which protrude from the termite mounds.
Roger Heim was a French botanist specialising in mycology and tropical phytopathology. He was known for his studies describing the anatomy of the mushroom hymenium, the systematics and phylogeny of higher fungi, the mycology of tropical fungi such as Termitomyces, as well as ethnomycological work on hallucinogenic fungi, like Psilocybe and Stropharia. In his career, he published over 560 articles, scientific reviews, and major works in fields like botany, chemistry, education, forestry, horticulture, liberal arts, medicine and zoology.
Phaeocollybia is a genus of fungi in the family Hymenogastraceae. They are characterized by producing fruit bodies (mushrooms) with umbonate caps and rough brown spores. The genus is widely distributed, and contains about 50 species. They are known for a long stipe which continues down into the ground, known as a rooting stipe or pseudorhiza formed as the fruitbody grows up from the subterranean colonized roots well below the organic soil layer. The genus is primarily mycorrhizal but may also be somewhat parasitic on forest trees.
Gyrodon is a genus of pored mushroom bearing close affinity to the genus Paxillus. Recent molecular research has confirmed this relationship of the two genera as sister taxa, together diverging as one of the most basal lineages in the Boletineae, and sister to the Boletaceae.
Phlebonema is a fungal genus in the family Agaricaceae. It is a monotypic genus, containing the single species Phlebonema chrysotingens, described by Roger Heim in 1929 from Madagascar. According to the Dictionary of the Fungi, the placement of this little-known genus in the Agaricaceae is uncertain.
Cryptomphalina is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Cryptomphalina sulcata, discovered in Thailand. French botanist Roger Heim circumscribed Cryptomphalina in 1966.
Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae. Known from Arizona, Colorado, central Mexico, India and Costa Rica, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of 2,000 to 4,000 m, typically in meadows or open, grassy conifer forests. The mushrooms have convex to bell-shaped caps 1.5–2 cm (0.6–0.8 in) in diameter, atop slender cylindrical stems that are up to 7.5 cm (3.0 in) long. The color of the caps changes with variations in hydration, ranging from dark chestnut brown to straw yellow or whitish when dry. The base of the stem is densely covered with conspicuous white rhizomorphs, a characteristic uncommon amongst Psilocybe species.
Psilocybe hoogshagenii is a species of psilocybin mushroom in the family Hymenogastraceae. The mushroom has a brownish conical or bell-shaped cap up to 3 cm (1.2 in) wide that has an extended papilla up to 4 mm long. The stem is slender and 5 to 9 cm long. The variety P. hoogshagenii var. convexa lacks the long papilla.
Amanita frostiana, also known as Frost's amanita, is a small fungus species of eastern U.S. and southeastern Canada. The mushroom varies in colours from yellow, red or reddish pink usually.
