Tyromyces chioneus |
Tyromyces is a genus of poroid fungi in the family Polyporaceae. It was circumscribed by mycologist Petter Karsten in 1881. [1] The type species is the widely distributed Tyromyces chioneus , commonly known as the white cheese polypore. [2] The phylogenetic position of Tyromyces within the Polyporales is uncertain, but it appears that it does not belong to the "core polyporoid clade". [3] 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." [4]
The genus name is derived from the Ancient Greek words τυρός ("cheese") and μύχης (fungus"). [5]
Tyromyces fungi have fruit bodies that are pileate (i.e., with a cap) to resupinate (crust-like). Fruit bodies are short-lived, and often mostly white, but turning a darker colour when dry. The colour of the pore surface is usually white to cream, sometime with greenish tinges. Like the cap surface, it darkens when dry. [6]
The hyphal system is either monomitic (meaning the fungus contains only generative hyphae, which in this case have clamps) or dimitic, containing both generative and skeletal hyphae. The spores are smooth, thin-walled, and hyaline (translucent). They are allantoid (long with rounded ends) to ovoid (egg-shaped), and are non-reactive with Melzer's reagent. There are no cystidia in the hymenium, although there may be cystidioles (sterile cells of about the same diameter and shape as an immature basidium that protrude beyond the surface of the hymenium). [6]
Tyromyces are white rot fungi with a cosmopolitan distribution. [6]
As of September 2016 [update] , Index Fungorum accepts 119 species of Tyromyces. [7]
Junghuhnia is a genus of crust fungi in the family Steccherinaceae. It was circumscribed by Czech mycologist August Carl Joseph Corda in 1842. The generic name honours German-Dutch botanist Franz Wilhelm Junghuhn.
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft to very tough. Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures. Many species are brackets, but others have a definite stipe – for example, Polyporus badius.
Perenniporia is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood.
Daedaleopsis is a genus of fungi in the family Polyporaceae. The name Daedaleopsis is a reference to Daedalus, the labyrinth-maker of myth. Similarly, the maze-like pattern of pores is taxonomically described as being daedaloid. DNA was recovered and sequenced from fragments of a nearly 7000-year-old fruit body of D. tricolor found in an early Neolithic village in Rome.
Fomitopsis is a genus of more than 40 species of bracket fungi in the family Fomitopsidaceae.
Postia is a genus of brown rot fungi in the family Fomitopsidaceae.
Gloeoporus is a genus of crust fungi in the family Irpicaceae. The genus has a widespread distribution.
Ceriporiopsis is a genus of fungi in the family Phanerochaetaceae. The genus is widely distributed, and, according to a 2008 estimate, contains about 25 species. Ceriporiopsis was circumscribed in 1963 by Polish mycologist Stanislaw Domanski. The genus is a wastebasket taxon, containing "species that share common macroscopic and microscopic characteristics, but are not necessarily related." Ceriporiopsis species are crust fungi that cause a white rot. They have a monomitic hyphal system, containing only generative hyphae, and these hyphae have clamp connections.
Ceriporia is a widely distributed genus of crust fungi.
Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.
Amauroderma is a genus of polypore fungi in the family Ganodermataceae. The genus, widespread in tropical areas, contains about 70 species. Amauroderma fungi are wood-decay fungi that feed and fruit on decayed branches and trunks.
Flaviporus is a genus of poroid fungi in the family Steccherinaceae.
Irpex is a genus of corticioid fungi in the order Polyporales. Species produce fruit bodies that grow as a crust on the surface of dead hardwoods. The crust features an irpicioid spore-bearing surface, meaning it has irregular and flattened teeth. Irpex is distinguished from the similar genera Junghuhnia and Steccherinum by the simple septa found in the generative hyphae.
Coriolopsis is a genus of fungi in the family Polyporaceae. It was circumscribed by American mycologist William Alphonso Murrill in 1905. The genus is cosmopolitan, with most species in tropical areas. The generic name combines the name Coriolus with the Ancient Greek word ὄψις ("appearance").
Dichomitus is a genus of poroid crust fungi in the family Polyporaceae. It was circumscribed by English mycologist Derek Reid in 1965.
Diplomitoporus is a genus of fungi in the family Polyporaceae. The Dictionary of the Fungi estimated the widespread genus to contain 11 species; since then, the genus has grown with the additional of several newly described species, and some transfers from other genera. Diplomitoporus has been described as a wastebasket taxon, containing "species that share common macroscopic and microscopic characteristics, but are not necessarily related."
Nigroporus is a genus of poroid fungi in the family Steccherinaceae. The genus was circumscribed by American mycologist William Alphonso Murrill in 1905. Nigroporus has a pantropical distribution. The genus name combines the Latin word niger ("black") with the Ancient Greek word πόρος ("pore").
Skeletocutis is a genus of about 40 species of poroid fungi in the family Polyporaceae. The genus has a cosmopolitan distribution, although most species are found in the Northern Hemisphere. It causes a white rot in a diverse array of woody substrates, and the fruit bodies grow as a crust on the surface of the decaying wood. Sometimes the edges of the crust are turned outward to form rudimentary bracket-like caps.
Anthoporia is a fungal genus in the family Meripilaceae. It is a monotypic genus, circumscribed in 2016 to contain the single species Anthoporia albobrunnea.
