Fomes fomentarius (L.) Fr. (1849) |
Fomes is a genus of perennial woody fungi in the family Polyporaceae. Species are typically hoof-shaped (ungulate). New growth each season is added to the margin, resulting in a downward extension of the hymenium. [1] This often results in a zonate appearance of the upper surface, that is, marked by concentric bands of color.
The name comes from Latin fomes, meaning "tinder", [2] from the use of Fomes fomentarius , also known as the tinder fungus, in making tinder (see amadou).[ citation needed ]
Fomes was first introduced by Elias Magnus Fries as a subgenus of Polyporus in his 1836 work Genera Hymenomycetum. He promoted it to generic status in 1849. [3]
Fomes species have perennial, hoof-shaped fruit bodies that attach directly to their substrate without a stipe. The cap surface has a hard smooth crust that ranges in colour from gray to blackish. On the underside of the cap, the pore surface is pale brown with small pores, and brown tube layers. The tough and fibrous context is pale brown. The fruit body becomes stratified after multiple years of growth. Fomes has a trimitic hyphal system, containing generative, skeletal, and binding hyphae. The generative hyphae have clamp connections, while binding and skeletal hyphae have pale brownish pigment that appears when they are mounted in a solution of potassium hydroxide. The cystidioles are fusoid, imbedded, or project somewhat. The basidia (spore-bearing cells) are club-shaped with a basal clamp, and have four sterigmata. The spores are cylindric, large, hyaline and smooth, and are non-reactive to Melzer's reagent. [4]
As of June 2017 [update] , Index Fungorum accepts 59 species of Fomes: [5]
Daedalea is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1801 by mycologist Christian Hendrik Persoon, based on the type D. quercina and four other species. The generic name is derived from the Ancient Greek δαιδαλεος.
Lentinus is a genus of fungi in the family Polyporaceae. The genus is widely distributed, with many species found in subtropical regions.
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.
Favolus, or honeycomb fungus, is a genus of fungi in the family Polyporaceae. The fruit bodies of Favolus species are fleshy with radially arranged pores on the underside of the cap that are angular and deeply pitted, somewhat resembling a honeycomb.
Hexagonia is a genus of poroid fungi in the family Polyporaceae. The genus has a widespread distribution, especially in tropical regions. The generic name is derived from the Latin word hexagonus, meaning "with six angles".
Lenzites is a widespread genus of wood-decay fungi in the family Polyporaceae. It was circumscribed by Elias Magnus Fries in 1835. The generic name honours German naturalist Harald Othmar Lenz (1798–1870).
Lignosus is a genus of polypore fungi in the family Polyporaceae. The genus was circumscribed in 1920 by mycologists Curtis Gates Lloyd and Camille Torrend, with L. sacer as the type species.
Lopharia is a genus of fungi in the family Polyporaceae. The genus was circumscribed by Károly Kalchbrenner and Peter MacOwan in 1881.
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."
Job Bicknell Ellis was a pioneering North American mycologist known for his study of ascomycetes, especially the grouping of fungi called the Pyrenomycetes. Born and raised in New York, he worked as a teacher and farmer before developing an interest in mycology. He collected specimens extensively, and together with his wife, prepared 200,000 sets of dried fungal samples that were sent out to subscribers in series between 1878 and 1894. Together with colleagues William A. Kellerman and Benjamin Matlack Everhart, he founded the Journal of Mycology in 1885, forerunner to the modern journal Mycologia. He described over 4000 species of fungi, and his collection of over 100,000 specimens is currently housed at the herbarium of the New York Botanical Gardens. Ellis had over 100 taxa of fungi named in his honor.
Fomes fomentarius is a species of fungal plant pathogen found in Europe, Asia, Africa and North America. The species produces very large polypore fruit bodies which are shaped like a horse's hoof and vary in colour from a silvery grey to almost black, though they are normally brown. It grows on the side of various species of tree, which it infects through broken bark, causing rot. The species typically continues to live on trees long after they have died, changing from a parasite to a decomposer.
Loweomyces fractipes is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Loweomyces. It is a widely distributed species, found in North America, Europe, Central America, South America, and Korea.
