Rolf Singer was a German mycologist and taxonomist of gilled mushrooms (agarics).
The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.
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.
Austroboletus is a genus of fungi in the family Boletaceae. The widely distributed genus contains species that form mycorrhizal relationships with plants.
Boletellus is a genus of fungi in the family Boletaceae. The genus has a widespread distribution, especially in subtropical regions, and contains about 50 species. The genus was first described by American mycologist William Alphonso Murrill in 1909. The genus name means "small Boletus".
Fistulinella is a genus of bolete fungi in the family Boletaceae. The genus has a pantropical distribution, and contains 15 species. Fistulinella was circumscribed by German mycologist Paul Christoph Hennings in 1901.
Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of B. castanella to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.
Rhodocollybia is a genus of Basidiomycete mushroom. Species in this genus, formerly classified as a subgenus in Collybia, have fairly large caps, and have a pinkish-tinted spore print. Microscopically, they are characterized by having spores and basidia that are dextrinoid—staining deep reddish to reddish-brown with Melzer's reagent when tested for amyloidity. Rhodocollybia species are commonly found in temperate North America and Europe, and infrequently in Central and South America.
Exsudoporus frostii, commonly known as Frost's bolete or the apple bolete, is a bolete fungus first described scientifically in 1874. A member of the family Boletaceae, the mushrooms produced by the fungus have tubes and pores instead of gills on the underside of their caps. Exsudoporus frostii is distributed in the eastern United States from Maine to Georgia, and in the southwest from Arizona extending south to Mexico and Costa Rica. A mycorrhizal species, its fruit bodies are typically found growing near hardwood trees, especially oak.
Gymnogaster is a genus of fungi in the family Boletaceae. It is a monotypic genus, containing the single secotioid species Gymnogaster boletoides, found in Australia. The fungus produces bright yellow fruit bodies with a light brown internal gleba, and the fruit bodies turn blue then dark brown after bruising or handling.
Suillus salmonicolor, commonly known as the Slippery Jill, is a fungus in the family Suillaceae of the order Boletales. First described as a member of the genus Boletus in 1874, the species acquired several synonyms, including Suillus pinorigidus and Suillus subluteus, before it was assigned its current binomial name in 1983. It has not been determined with certainty whether S. salmonicolor is distinct from the species S. cothurnatus, described by Rolf Singer in 1945. S. salmonicolor is a mycorrhizal fungus—meaning it forms a symbiotic association with the roots of plants such that both organisms benefit from the exchange of nutrients. This symbiosis occurs with various species of pine, and the fruit bodies of the fungus appear scattered or in groups on the ground near the trees. The fungus is found in North America, Hawaii, Asia, the Caribbean, South Africa, Australia and Central America. It has been introduced to several of those locations via transplanted trees.
Sutorius is a genus of fungi in the family Boletaceae. Its type species is the widely distributed Sutorius eximius. The Asian Boletus obscureumbrinus, found in Japan and China, was described by Japanese mycologist Tsuguo Hongo in 1968, moved to genus Sutorius in 2016, but then reclassified into genus Neoboletus in 2019. The Australian Sutorius australiensis and the southern Chinese Sutorius subrufus also belong to the genus.
Phylloporus arenicola is a species of bolete mushroom in the family Boletaceae. It is found in the Pacific Northwest region of western North America, where it grows in sand dunes in a mycorrhizal association with pine trees. It is one of only three North American Boletaceae species that occur in coastal sand dunes.
Neoboletus pseudosulphureus is a species of bolete fungus in the family Boletaceae. It is found in Europe, Central America, North America, and India, where it grows in deciduous and mixed forests. Initially uniformly yellow in color, all external surfaces of the fruit body undergo a variety of discolorations as it matures.
Pulveroboletus ravenelii, commonly known as Ravenel's bolete or the powdery sulfur bolete, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1853, the widely distributed species is known from Asia, Australia, North America, Central America, and South America. Mycorrhizal with oak, the fungus fruits on the ground singly, scattered, or in groups in woods. Fruit bodies (mushrooms) have convex to flat, yellowish to brownish-red caps up to 10 cm (4 in) in diameter. On the cap underside, the pore surface is bright yellow before turning dingy yellow to grayish brown with age; it stains greenish blue then grayish brown after injury. A cottony and powdery partial veil remains as a ring on the stipe. The mushrooms are edible, and have been used in traditional Chinese medicine and for mushroom dyeing.
Buchwaldoboletus lignicola is a species of bolete fungus in the family Boletaceae native to Europe and North America. Found on wood, it is actually parasitic on the fungus Phaeolus schweinitzii. It has a convex yellow- to rusty brown cap, yellow to yellow-brown pores and stipe, and a brown spore print. Its edibility is unknown.
Austroboletus lacunosus is a bolete fungus native to Australia.
Austroboletus mutabilis is a species of bolete fungus found in northern Australia. Described as new to science in 2006, it grows in dry sclerophyll woodlands. This bolete is characterised by its colour change—from deep red to orange and, finally, to yellow—that occurs in the cap. Almost no other Bolete goes through such a dramatic colour change as this species and this change may occur as a consequence of time, exposure to sunlight and/or local humidity.
Dr Teresa Lebel is a taxonomist and ecologist who works on fungi, with a particular interest in subterranean truffle-like fungi and their mushroom, bolete, bracket or cup relatives.
