Helicobasidium purpureum is a species of fungus in the subdivision Pucciniomycotina. Basidiocarps are corticioid (patch-forming) and are typically violet to purple. Microscopically they have auricularioid basidia. Helicobasidium purpureum is an opportunistic plant pathogen and is one of the causes of violet root rot of crops and other plants. DNA sequencing suggests that it is a complex of more than one species. The species has a conidia-bearing anamorph in the Tuberculina persicina complex that is a parasite of rust fungi.
Ceratobasidium cornigerum is a species of fungus in the order Cantharellales. Basidiocarps are thin, spread on the substrate out like a film (effused) and web-like. An anamorphic state is frequently obtained when isolates are cultured. Ceratobasidium cornigerum is saprotrophic, but is also a facultative plant pathogen, causing a number of economically important crop diseases, and an orchid endomycorrhizal associate. The species is genetically diverse and is sometimes treated as a complex of closely related taxa. DNA research shows the species actually belongs within the genus Rhizoctonia.
Corticium invisum is a species of fungus in the class Agaricomycetes. It is a corticioid fungus and a plant pathogen, the causal agent of black rot of tea, and was originally described from Sri Lanka. Corticium invisum has never been redescribed or reviewed and is unlikely to be a species of Corticium in the modern sense. Roberts (1999) referred Petch's original specimens to Ceratobasidium cornigerum.
Corticium penicillatum is a species of fungus in the class Agaricomycetes. It is a corticioid fungus and a plant pathogen, the causal agent of coconut thread blight, a leaf disease of coconut palms. The species was originally described from Papua New Guinea in 1925 and has since been reported from Vanuatu, Fiji, and the Solomon Islands. Corticium penicillatum has never been redescribed or reviewed and is unlikely to be a species of Corticium in the modern sense.
Corticium roseum is a species of fungus in the family Corticiaceae. Basidiocarps are effused, smooth, corticioid, and pink. The species has a wide, north and south temperate distribution and in Europe is typically found on dead, attached branches of Salix and Populus.
Rhizoctonia noxia is a species of fungus in the order Cantharellales. Basidiocarps are thin, effused, and web-like. The species is tropical to sub-tropical and is mainly known as a plant pathogen, the causative agent of "kole-roga" or black rot of coffee and various blights of citrus and other trees.
The Corticiaceae are a family of fungi in the order Corticiales. The family formerly included almost all the corticioid fungi, whether they were related or not, and as such was highly artificial. In its current sense, however, the name Corticiaceae is restricted to a comparatively small group of corticioid genera within the Corticiales.
Terana caerulea, commonly known as the cobalt crust fungus or velvet blue spread, is a saprobic crust fungus in the family Phanerochaetaceae. Usually found in warm, damp hardwood forests on the undersides of fallen logs and branches of deciduous trees, this unique fungus has been described as "blue velvet on a stick". This species was chosen as fungus of the year for 2009 by the German Mycological Society.
Peniophora is a genus of fungi which are plant pathogens. Members of the genus belong to the class Agaricomycetes, order Russulales, and family Peniophoraceae. The genus is widespread, and contains 62 species. The species of Peniophora are resupinate, or crust-like, and are described as corticioid. A number of its members are parasitised by other fungi. For example, Tremella mesenterica is a parasite to several species of Peniophora.
Corticium is a genus of fungi in the family Corticiaceae. Basidiocarps are effused, corticioid, smooth, and grow on dead wood. One species, C. silviae, is lichenicolous. The genus was formerly used in a very wide sense for almost any effused corticioid fungi.
Sebacina is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees and other plants. Basidiocarps are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused (corticioid) to coral-shaped (clavarioid). The genus has a cosmopolitan distribution.
The corticioid fungi are a group of fungi in the Basidiomycota typically having effused, smooth basidiocarps that are formed on the undersides of dead tree trunks or branches. They are sometimes colloquially called crust fungi or patch fungi. Originally such fungi were referred to the genus Corticium and subsequently to the family Corticiaceae, but it is now known that all corticioid species are not necessarily closely related. The fact that they look similar is an example of convergent evolution. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "corticioid fungi" and this term is frequently used in research papers and other texts.
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus Hydnum, but it is now known that not all hydnoid species are closely related.
Ceratobasidium is a genus of fungi in the order Cantharellales. Basidiocarps are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Anamorphic forms were formerly referred to the genus Ceratorhiza, but this is now considered a synonym of Rhizoctonia. Ceratobasidium species, excluding the type, are also now considered synonymous with Rhizoctonia and some species have been transferred to the latter genus. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids.
Rhizoctonia is a genus of fungi in the order Cantharellales. Species form thin, effused, corticioid basidiocarps, but are most frequently found in their sterile, anamorphic state. Rhizoctonia species are saprotrophic, but some are also facultative plant pathogens, causing commercially important crop diseases. Some are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi.
The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Rhizoctonia, both of which contain plant pathogenic species causing diseases of commercial crops and turf grass.
Crustodontia is a fungal genus of uncertain familial placement in the order Polyporales. The genus was circumscribed in 2005 to contain the crust fungus Crustodontia chrysocreas. This species was originally described as Corticium chrysocreas by Miles Berkeley and Moses Ashley Curtis in 1873. Their description was as follows: "Subiculum bright yellow, thin; hymenium immarginate pallid, or yellow tinged with tawny." Crustodontia has a monomitic hyphal system, meaning it contains only generative hyphae, and these hyphae have clamp connections.
Amphinema byssoides is a species of corticioid fungus known to form mycorrhizal relationships with spruce trees.
Botryobasidium is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution.
Tremella versicolor is a species of fungus in the family Tremellaceae. It produces small, pustular, gelatinous basidiocarps and is parasitic on the basidiocarps of Peniophora species, a genus of corticioid fungi, on dead attached or recently fallen branches. It was originally described from England.
