Leifiporia is a genus of two species of poroid white rot crust fungi in the family Polyporaceae. The genus was circumscribed by Chinese mycologists in 2016 to accommodate the type species Leifiporia rhizomorpha . [1]

Taxonomy

Leifiporia was circumscribed in 2016 by Chinese mycologists Changlin Zhao, Fang Wu, and Yu-Cheng Dai. Molecular analysis shows that Leifiporia belongs to the "core polyporoid clade", [1] a grouping of fungi roughly equivalent to the family Polyporaceae. [2] [3] The generic name honours Norwegian mycologist and polypore specialist Leif Ryvarden. The genus is phylogenetically close to the fungi Diplomitoporus overholtsii and Lopharia cinerascens . It also groups near Pycnoporus and Trametes . A new combination, Leifiporia eucalypti , was proposed by the authors. This fungus, originally described as Dichomitus eucalypti by Ryvarden in 1985, is found in Australia. [4]

Description

Leifiporia species are characterized by crust-like fruit bodies with an annual growth habit. Their pore surface is white to cream. Leifiporia has a dimitic hyphal system, containing both generative and skeletal hyphae. The generative hyphae have clamp connections and branch mostly at right angles. The skeletal hyphae are present in the subiculum only and distinctly thinner than the generative hyphae. The spores are ellipsoid, hyaline, thin-walled, and smooth. They usually contain one or two oil droplets. [1]

Habitat and distribution

The type species L. rhizomorpha has been collected from Anhui and Zhejiang provinces in eastern China. In both cases, the fungus was growing on a fallen angiosperm branch. Leifiporia eucalypti is found in the Northern Territory of Australia, where it grows on Eucalyptus camaldulensis . Both species cause white rot. [1]

<span class="mw-page-title-main">Polyporaceae</span> Family of fungi

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.

Abundisporus is a small genus of poroid fungi currently with seven recognized species. They differ from other polypores in having coloured rather than hyaline spores.

<span class="mw-page-title-main">Meruliaceae</span> Family of fungi

The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. As of April 2018, Index Fungorum accepts 645 species in the family.

<i>Daedaleopsis</i> Genus of fungi

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.

<i>Haploporus</i> (fungus) Genus of fungi

Haploporus is a genus of poroid fungi in the family Polyporaceae.

<i>Ceriporiopsis</i> Genus of fungi

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.

Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.

Loweomyces is a genus of six species of poroid fungi in the family Steccherinaceae.

<i>Dichomitus</i> Genus of fungi

Dichomitus is a genus of poroid crust fungi in the family Polyporaceae. It was circumscribed by English mycologist Derek Reid in 1965.

Megasporoporia is a genus of four species of crust fungi in the family Polyporaceae. The genus is characterized by its large spores, and dextrinoid skeletal hyphae.

<i>Nigroporus</i> Genus of fungi

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").

<i>Pachykytospora</i> Genus of fungi

Pachykytospora is a small genus of poroid fungi in the family Polyporaceae. Species in the cosmopolitan genus cause white rot. There are about 10 species in the genus, with newest member described from European Russia in 2007. Pachykytospora species have fruit bodies that are resupinate, with light brown tubes. They are characterized by their uneven, ellipsoid spores, and the Polyporus-like skeletal-binding hyphae.

<i>Skeletocutis</i> Genus of fungi

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.

Obba is a genus of three species of poroid, white rot crust fungi in the family Gelatoporiaceae. The genome sequence of the type species, O. rivulosa, was reported in 2016.

<i>Datroniella</i> Genus of fungi

Datroniella is a genus of poroid crust fungi in the family Polyporaceae. It was circumscribed in 2014 by Chinese mycologists as a segregate genus from Datronia. Datroniella differs from Datronia by their moderately to frequently branched skeletal hyphae in the context, and absence of dendrohyphidia. The type species of Datroniella is D. scutellata, a fungus originally described as Polyporus scutellatus by Lewis David de Schweinitz. Datroniella fungi cause a white rot, usually on angiosperm wood.

<i>Rhodofomitopsis</i> Genus of fungi

Rhodofomitopsis is a genus of four species of poroid fungi in the family Fomitopsidaceae. It was circumscribed by Chinese mycologists in 2016, with Rhodofomitopsis feei as the type species. Rhodofomitopsis is a distinct lineage of fungi that were previously placed in genus Fomitopsis. The generic name alludes to this resemblance to Fomitopsis and the violaceous pore surface.

Fragiliporia is the sole genus in the fungus family Fragiliporiaceae. It contains the poroid crust fungus Fragiliporia fragilis, described as new to science by Chinese mycologists in 2014. The type specimen of this fungus was discovered growing on a rotting stump of alder in the Gaoligongshan National Nature Reserve in Yunnan. The specific epithet fragilis refers to the brittle fruit bodies of the fungus. Molecular phylogenetics shows that the fungus is in an isolated position in the Polyporales, distinct from the six previously identified clades in this order. In a later study (2017), Fragiliporia was recovered in a phylogenetically isolated position as sister to Candelabrochaete africana.

Neodatronia is a genus of two species of poroid crust fungi in the family Polyporaceae. It was circumscribed in 2014 by Chinese mycologists Bao-Kai Cui, Hai-Jiao Li, and Yu-Cheng Dai as a segregate genus from Datronia. Neodatronia fungi differ microscopically from Datronia by having moderately to frequently branched skeleto-binding hyphae in the context, and by their somewhat smaller spores.

Ungulidaedalea is a fungal genus in the family Fomitopsidaceae. The genus was circumscribed by Chinese mycologists in 2016 to contain the single species Ungulidaedalea fragilis, a fungus that was described as new in 2014 with the name Fomitopsis fragilis. The holotype of this fungus was collected in Jianfengling Nature Reserve, in Ledong County (Hainan). The generic name Ungulidaedalea refers to the resemblance between this species and Daedalea, and also to the hoof-shaped (ungulate) form of the fruit body. Ungulidaedalea fragilis has rather fragile fruit bodies with a dark brown crust and large angular pores on the cap underside. Microscopic characteristics include its densely septated skeletal hyphae, and oblong-ellipsoid spores that measure 4–5.2 by 2.2–2.8 μm.
