Fomitopsis mounceae is a species of shelf fungus. Originally thought to be identical to the red-belted conk, studies show that it is in fact a discrete species. [1] The original specimen was isolated from Edson, Alberta on a poplar tree. [1] This species was named after Irene Mounce, a Canadian mycologist.

It causes cubical brown rot typical of Fomitopsis , and favours aspen or coniferous trees. It is a detritivore, and does not typically grow on live trees. It typically grows at lower elevations than its close relative, F. schrenkii.

Description

Fomitopsis mounceae is a perennial woody conk distributed across Canada and the northern United States, down to northern California. [1] It is typically fan-like in shape, with distinct bands usually brown or red in colour. [1] It can have a resinous, sticky coating. [1] As the conks age, they often become bumpy or warty. [1] The underside of the conk is typically white or yellow in colour, with 3–6 round pores per millimetre. [1] If broken open, the inside is woody and brown, with no distinct bands. [1] It stains brown in KOH.

Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.

<span class="mw-page-title-main">Polypore</span> Group of fungi

Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside. They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. Over one thousand polypore species have been described to science, but a large part of the diversity is still unknown even in relatively well-studied temperate areas.

<i>Fomitopsis betulina</i> Common bracket fungus

Fomitopsis betulina, commonly known as the birch polypore, birch bracket, or razor strop, is a common bracket fungus and, as the name suggests, grows almost exclusively on birch trees. The brackets burst out from the bark of the tree, and these fruit bodies can last for more than a year.

The tiger snake is a large and highly venomous snake of southern Australia, including its coastal islands and Tasmania. These snakes are often observed and locally well known by their banding, black and yellow like a tiger, although the species can be highly variable in colouration and patterning. All populations are classified within the genus Notechis (Elapidae). Their diverse characteristics have been classified either as distinct species or by subspecies and regional variation.

<i>Fomitopsis pinicola</i> Stem decay fungus

Fomitopsis pinicola, is a stem decay fungus common on softwood and hardwood trees. Its conk is known as the red-belted conk. The species is common throughout temperate Europe and Asia. It is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems. It influences stand structure and succession in temperate rainforests. It performs essential nutrient cycling functions in forests. As well as a key producer of brown rot residues that are stable soil components in coniferous forest ecosystems. It has been reported that mushrooms have significant antioxidant activity.

Echinodontium tinctorium, commonly known as the Indian paint fungus or toothed conk, is a species of fungus in the family Echinodontiaceae. It is a plant pathogen. Found on tree species such as grand fir.

<i>Rhodofomes cajanderi</i> Species of fungus

Rhodofomes cajanderi is a widely distributed species of bracket fungus. Commonly known as the rosy conk due to its rose-colored pore surface, it causes a disease called a brown pocket rot in various conifer species. It is inedible. It is widespread in western North America, with more prevalence in southern climates. It has a particular preference for higher-altitude spruce forests.

<i>Rhodofomes roseus</i> Type of fungus

Rhodofomes roseus is a species of pink polypore found in western North America and Europe. This is a close relative of another species of pink conk, the rosy conk. While R. cajanderi is a plant pathogen, R. rosea is a detritivore.

<i>Laricifomes officinalis</i> Species of fungus

Laricifomes officinalis, also known as agarikon, eburiko, or the quinine conk, is a wood-decay fungus that causes brown heart rot on conifers native to Europe, Asia, and North America, as well as Morocco. This fungus is the only member of the genus Laricifomes, in the order Polyporales. The fruiting bodies grow in large conks on the trunks of trees.

<i>Porodaedalea pini</i> Species of fungus

Porodaedalea pini, commonly known as the pine conk, is a species of fungus in the family Hymenochaetaceae. It is a plant pathogen that causes tree disease commonly known as "red ring rot" or "white speck". This disease, extremely common in the conifers of North America, decays tree trunks, rendering them useless for lumber. It is a rot of the heartwood. Signs of the fungus include shelf-shaped conks protruding from the trunks of trees. Spores produced on these conks are blown by the wind and infect other trees. Formal management of this disease is limited, and the disease is controlled primarily by cultural practices. Red ring rot is an important forest disturbance agent and plays a key role in habitat formation for several forest animals.

<i>Fomes fasciatus</i> Species of fungus

Fomes fasciatus, common name the Southern Clam Shell, is a pathogenic white rot fungus in the family Polyporaceae. It is found in the southeastern United States and Central and South America where it can be seen growing on various dead and living hardwood trees. It was first described by Swedish botanist Olof Swartz in Jamaica in 1788 as Boletus fasciatus. It was later transferred by Cooke to Fomes fasciatus in 1885. The genus name "Fomes" translates to tinder as its holotype was historically used to start fires and the specific epithet "fasciatus" translates to "banded", in reference to the bands of brown to grey and black colors that the top of its fruiting body displays.

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.

<i>Fomitopsis ochracea</i> Species of fungus

Fomitopsis ochracea is a polypore fungus found in North America. It was isolated from Albertan forests, and can be found in British Columbia. It has been isolated as far East as Newfoundland, but prefers Northern climates. It can be isolated throughout the Appalachian range, as far down as Georgia. It is a detritivore on both hardwood trees and conifers, causing a brown cubical rot. It is a member of the genus Fomitopsis, a common group of perennial fungi.

<i>Fomitopsis schrenkii</i> Species of fungus

Fomitopsis schrenkii is a newly isolated species from the genus Fomitopsis. Previously thought to be identical to the red-belted conk, DNA analysis shows it is in fact a distinct species. This species is named after Herman von Schrenk, a respected name in forest pathology. It occurs most frequently in the Southwestern United States, and has a somewhat limited range. It prefers coniferous trees and rarely associates on hardwoods. This substrate preference and location range is most helpful in distinguishing F. schrenkii from its close relative, F. mounceae.
