Truncospora is a genus of 10 species of fungi in the family Polyporaceae.

Contents

Taxonomy

The genus was originally proposed by Czech mycologist Albert Pilát in 1941, [1] but this publication is invalid because a type species was not designated, contrary to the rules of botanical nomenclature. [2] He published the genus validly in 1953 with two species: Truncospora oboensis , and the type, T. ochroleuca. [3] Leif Ryvarden placed the genus in synonymy with Perenniporia in 1972, [4] but molecular studies have shown that Truncospora is distinct genetically, and comprises part of the "core polyporoid clade", a grouping of fungi roughly equivalent to the family Polyporaceae. [5] [6]

The generic name Truncospora is derived from the Latin trunco ("I cut off") and the Ancient Greek σπορά ("spore"). [7]

Description

Truncospora is characterized by relatively small, cap-forming fruit bodies that generally measure about 1.5–3 cm (0.6–1.2 in) long, 2.5–3.5 cm (1.0–1.4 in) wide, and 1–4 cm (0.4–1.6 in) thick. The skeletal hyphae range from non-dextrinoid to dextrinoid, and the spores are truncate and strongly dextrinoid. [3] [8]

Species

As of July 2017, Index Fungorum accepts 10 species of Truncospora:

<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.

<i>Perenniporia</i> Genus of fungi

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.

<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>Daedalea</i> Genus of fungi

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.

<i>Fomitopsis</i> Genus of fungi

Fomitopsis is a genus of more than 40 species of bracket fungi in the family Fomitopsidaceae.

<i>Postia</i> Genus of fungi

Postia is a genus of brown rot fungi in the family Fomitopsidaceae.

<i>Antrodia</i> Genus of fungi

Antrodia is a genus of fungi in the family Fomitopsidaceae. Antrodia species have fruit bodies that typically resupinate, with the hymenium exposed to the outside; the edges may be turned so as to form narrow brackets. Most species are found in temperate and boreal forests, and cause brown rot.

<i>Gloeoporus</i> Genus of fungi

Gloeoporus is a genus of crust fungi in the family Irpicaceae. The genus has a widespread distribution.

<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.

<i>Ceriporia</i> Genus of fungi

Ceriporia is a widely distributed genus of crust fungi.

Grammothele is a genus of poroid crust fungi in the family Polyporaceae.

Grammothelopsis is a fungal genus in the family Polyporaceae. It was circumscribed in 1982 by Swiss mycologist Walter Jülich, with Grammothelopsis macrospora as the type species.

<i>Leptoporus</i> Genus of fungi

Leptoporus is a genus of polypore fungi. The type species, Leptoporus mollis, is widespread throughout north temperate areas. The generic name is derived from the Ancient Greek words λεπτός ("thin") and πόρος ("pore").

<i>Microporellus</i> Genus of fungi

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

<i>Pyrofomes</i> Genus of fungi

Pyrofomes is a genus of fungi in the family Polyporaceae. The genus was circumscribed by Czech mycologists František Kotlaba and Zdenek Pouzar in 1964. The type species, Pyrofomes demidoffii, was once considered a widespread species with a distribution that included East Africa, Middle Asia, Europe, and North America. DNA evidence demonstrated that North American collections represented a lineage that was different than European collections. The North American sibling was reinstated as P. juniperinus in 2017.

<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.

<i>Sarcoporia</i> Genus of fungi

Sarcoporia is a genus of polypore fungi in the family Polyporaceae. The genus was circumscribed by Petter Karsten in 1894, with the widespread fungus Sarcoporia polyspora as the type species. The genus name combines the Ancient Greek words σάρξ ("flesh") and πόρος ("pore").

Yuchengia is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Yuchengia narymica, a crust fungus formerly placed in the genus Perenniporia and originally described as Trametes narymica by Czech mycologist Albert Pilát.

Truncospora macrospora is a species of poroid fungus in the family Polyporaceae. It was described as new to science in 2013 by Chinese mycologists Bao-Kai Cui and Chang-Lin Zhao. The fungus, found in southwest China, is distinguished by its annual growth habit, and the distinct dark brownish crust on its caps. The semicircular caps measure about 1.5–3 cm (0.6–1.2 in) long, 2.5–3.5 cm (1.0–1.4 in) wide, and 1–4 cm (0.4–1.6 in) thick. Microscopic characteristics include its relatively large spores, measuring 16.5–19.5 by 8.0–9.5 μm, which have a strongly dextrinoid reaction. The type was collected in the Gaoligong Mountains at an altitude of 2,400 metres (7,900 ft), where it was found growing on a fallen angiosperm branch.
