Pisolithus is a genus of fungi within the family Sclerodermataceae (suborder Sclerodermatineae). [2]
As accepted by Species Fungorum; [3]
Former species (all Sclerodermataceae family); [3]
The Russulaceae are a diverse family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the brittlegills and the milk-caps, well-known mushroom-forming fungi that include some edible species. These gilled mushrooms are characterised by the brittle flesh of their fruitbodies.
Rhizopogon is a genus of ectomycorrhizal basidiomycetes in the family Rhizopogonaceae. Species form hypogeous sporocarps commonly referred to as "false truffles". The general morphological characters of Rhizopogon sporocarps are a simplex or duplex peridium surrounding a loculate gleba that lacks a columnella. Basidiospores are produced upon basidia that are borne within the fungal hymenium that coats the interior surface of gleba locules. The peridium is often adorned with thick mycelial cords, also known as rhizomorphs, that attach the sporocarp to the surrounding substrate. The scientific name Rhizopogon is Greek for 'root' (Rhiz-) 'beard' (-pogon) and this name was given in reference to the rhizomorphs found on sporocarps of many species.
Alexander Hanchett Smith was an American mycologist known for his extensive contributions to the taxonomy and phylogeny of the higher fungi, especially the agarics.
Crepidotus is a genus of fungi in the family Crepidotaceae. Species of Crepidotus all have small, convex to fan-shaped sessile caps and grow on wood or plant debris. The genus has been studied extensively, and monographs of the North American, European, and Neotropical species have been published.
Gautieria is a genus of hypogeal fungi in the family Gomphaceae. They form mycorrhizae with various tree species, mostly from the family Pinaceae. Species are present over much of the world's temperate and boreal forest habitats. It is well documented that species from this genera are an important part of the diet of the northern flying squirrel. Also, some Australian marsupials, especially the rat-kangaroos, feed extensively on these fungi. The fungi also benefit from this relationship: not only do the squirrels help to disperse the spores and propagate the species, studies suggest that passage through the digestive tract of a mammal promotes germination of spores.
Resupinatus is a genus of fungi in the family Tricholomataceae. Species are saprobic, and often found growing on the underside of decaying wood or sides of decaying woody substrates. The generic name is derived from the Latin resupinus.
Phlebia is a genus of mostly crust fungi in the family Meruliaceae. The genus has a widespread distribution. Phlebia species cause white rot.
Astraeus hygrometricus, commonly known as the hygroscopic earthstar, the barometer earthstar, or the false earthstar, is a species of fungus in the family Diplocystaceae. Young specimens resemble a puffball when unopened. In maturity, the mushroom displays the characteristic earthstar shape that is a result of the outer layer of fruit body tissue splitting open in a star-like manner. The false earthstar is an ectomycorrhizal species that grows in association with various trees, especially in sandy soils. A. hygrometricus was previously thought to have a cosmopolitan distribution, though it is now thought to be restricted to Southern Europe, and Astraeus are common in temperate and tropical regions. Its common names refer to the fact that it is hygroscopic (water-absorbing) and can open up its rays to expose the spore sac in response to increased humidity, then close them up again in drier conditions. The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the spores mature. The spores are reddish-brown and roughly spherical with minute warts, measuring 7.5–11 micrometers in diameter.
Astraeus is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushroom. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of Astraeus grow on the ground in ectomycorrhizal associations with trees and shrubs. Despite their similar appearance to the Geastrum earthstars, the species of Astraeus are not closely related.
Tyromyces is a genus of poroid fungi in the family Polyporaceae. It was circumscribed by mycologist Petter Karsten in 1881. The type species is the widely distributed Tyromyces chioneus, commonly known as the white cheese polypore. The phylogenetic position of Tyromyces within the Polyporales is uncertain, but it appears that it does not belong to the "core polyporoid clade". Tyromyces is polyphyletic as it is currently circumscribed, and has been described as "a dumping place for monomitic white-rot species with thin-walled spores."
Otidea is a genus of fungi in the family Pyronemataceae. The genus is widely distributed in northern temperate regions.
Octaviania is a genus of truffle-like fungi in the family Boletaceae. The widespread genus is estimated to contain 15 species.
Astraeus asiaticus is a species of false earthstar in the family Diplocystaceae. Described as a new species in 2007, it was originally found in north and northeastern areas of Thailand, where it grows in sandy or laterite-rich soil in dry lowland dipterocarp forests. The species has a wide distribution in Asia.
Astraeus odoratus is a species of false earthstar in the family Diplocystaceae. Described as a new species in 2004, it was originally found in the Thai highlands growing in sandy or laterite-rich soil in dry lowland dipterocarp forests. The species is found in Southeast Asia.
Sclerodermatineae is a suborder of the fungal order Boletales. Circumscribed in 2002 by mycologists Manfred Binder and Andreas Bresinsky, it contains nine genera and about 80 species. The suborder contains a diverse assemblage fruit body morphologies, including boletes, gasteroid forms, earthstars, and puffballs. Most species are ectomycorrhizal, although the ecological role of some species is not known with certainty. The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
James Martin Trappe is a mycologist and expert in the field of North American truffle species. He has authored or co-authored 450 scientific papers and written three books on the subject. MycoBank lists him as either author or co-author of 401 individual species, and over the course of his career he has helped guide research on mycorrhizal fungi, and reshaped truffle taxonomy: establishing a new order, two new families, and 40 individual genera.
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.
