Belongs within: Tremellales. Tremella is a genus of fungi parasitic on other fungi. Fruiting bodies, when present, are gelatinous; many species also have an anamorphic yeast form. Characters (from R. J. Bandoni): Sporocarps conidial or basidial; conidia not arising as conjugating pairs; basidia typically single, terminal, rarely catenate and virtually always producing epibasidia and ballistospores;… Continue reading Tremella

Belongs within: Russula. Lactarius is a genus of fungi producing mushroom-like fruiting bodies with an abundant latex. Molecular analysis indicates that the gasteroid genera Arcangeliella and Zelleromyces are nested within Lactarius (Miller et al. 2001). Characters (from Miller et al. 2001): Basidiome with an abundant latex, radially arranged lamellae, a pileus, a well developed stipe,… Continue reading Lactarius

Belongs within: Psathyrellaceae. Coprinellus is a genus of lignicolous, terrestrial or coprophilous species of coprinoid mushrooms. Characters (from Redhead et al. 2001): Veil (usually of globular cells) present and/or bearing superficial lageniform to bulbous-based filament-bearing cells (setulae) converted into secretory round-tipped pileocystidia; lamellae and pileus fully, partially, or non-deliquescent during sporulation, if non-deliquescent some have… Continue reading Coprinellus

Belongs within: Agaricomycetes. The Stereaceae is a group of fungi producing usually non-stalked fruiting bodies, often growing on wood. Phylogenetic analysis suggests that the genus Aleurodiscus is paraphyletic to other genera in the family (Binder et al. 2005). Characters (from Cannon & Kirk 2007, for Stereaceae): Basidiomata appressed, effused-reflexed or discoid, rarely stalked, the outer… Continue reading Aleurodiscus

Belongs within: Polyporaceae. Polyporus is a genus of wood-growing fungi causing white rot. Characters (from Sotome et al. 2008): Basidiocarps stipitate, growing on wood or arising from a sclerotium; hyphal system dimitic with arboriform vegetative hyphae; basidiospores cylindric, smooth; causing a white rot. Polyporus Fr. 1815 (see below for synonymy)KC01 |–+–*P. tuberasterJM17, BH05 | `–P.… Continue reading Polyporus

Belongs within: Agaricales.Contains: Tricholoma, Gloeostereae. The Tricholomataceae is a family of ectomycorrhizal mushroom-producing fungi, found in coniferous and broadleaved forests. Members of this group include the white rot-producing honey fungus Armillaria, an individual of which in Oregon has been described as the world’s largest known organism. Characters (from Cannon & Kirk 2007): Basidiomata pileate and… Continue reading Tricholomataceae

Belongs within: Agaricomycetidae.Contains: Hymenogasteraceae, Pleurotus, Tricholomataceae, Entolomataceae, Pluteaceae, Cortinariaceae, Psathyrellaceae, Agaricaceae, Nidulariaceae. The Agaricales are a clade within the basidiomycetes identified by molecular analyses, but which lack clear morphological synapomorphies. The majority of Agaricales produce gilled fruiting bodies (the classic ‘mushroom’), but a number of subgroups produce different fruiting forms, such as various gasteroid taxa. Agaricales… Continue reading Agaricales

Belongs within: Agaricales. The Cortinariaceae is a family of mushroom-producing fungi, members of which are the dominant ectomycorrhizal group in many temperate forests. Characters (from Cannon & Kirk 2007): Basidiomata pileate or gasteroid, membranous to fleshy, often brightly coloured, typically yellowish, reddish or brownish, the cap dry, silky, fibrose, scaly, or slimy and glutinous, sometimes… Continue reading Cortinariaceae
