Picipes badius (formerly Royoporus badius), commonly known as the black-footed polypore or black-leg, is a species of fungus in the family Polyporaceae. It causes a white rot of hardwoods and conifers. The species is found in temperate areas of Asia, Australia, Europe, and North America. It has a dark brown or reddish-brown cap that reaches a diameter of 25 cm (9.8 in), and a stipe that is often completely black or brown at the top and black at the base.

Taxonomy

The species was first described in the scientific literature in 1801 by Christian Hendrik Persoon, who named it Boletus badius. [2] American mycologist Lewis David de Schweinitz transferred the species to Polyporus in 1832, and it was known by this name until 1997, when De transferred the species into the genus Royoporus , [3] which he had described the year before. [4] Polyporaceae species that are closely phylogenetically related to Picipes badius include Polyporus dictyopus , Polyporus melanopus , and Polyporus tubaeformis , which have clamp connections on generative hyphae and a similar ecology. [5] Zmitrovich & Kovalenko proposed the new genus Picipes for this fungus together with P. melanopus and P. tubaeformis and according to Species Fungorum Picipes badius is now the correct current name. [6]

The specific epithet badius derives from the Latin root badi-, meaning "reddish brown". [7] The common names "black-footed polypore" [8] and "black-leg" refer to its characteristic dark-colored stipe. [7]

Description

The mushroom's common names refer to its blackish stipe. Polyporus.badius2.-.lindsey.jpg
The mushroom's common names refer to its blackish stipe.

The fruit bodies of Picipes badius tend to be upright, growing solitary or in groups, sometimes with two or more fruit bodies arising from a common stipe. The cap is circular or kidney-shaped, and often lobed or with a wavy edge.

When young, the fruit bodies are convex, then become flat or funnel-shaped in maturity, reaching dimensions of 5–25 cm (2.0–9.8 in) across by 1–4 mm (0.04–0.16 in) thick. The upper cap surface is smooth and glossy, but develops radial wrinkles as it ages. The color of the cap is brown, often darker in the center and lighter-colored at the margins. The under-surface is white or cream-colored, yellowing when old. Pores are round and number 6–8 per mm, with decurrent tubes (running down the length of the stipe). The stipe, attached to the cap either centrally or laterally, is 2–8 cm (0.8–3.1 in) long by 0.5–1.5 cm (0.2–0.6 in) thick, velvety and dark brown to blackish-brown, black and longitudinally wrinkled when old. [9] The fruit bodies are inedible because of their tough texture. [7]

The spores are ellipsoid or cylindrical, hyaline (translucent), smooth, and 7.5–9 by 3–5  μm. The basidia (spore-bearing cells) are club-shaped with a narrow base, and have dimensions of 20–30 by 7–9 μm. Like other members of the genus Polyporus, this species has a dimitic hyphal construction, meaning that the hyphae are made of both generative hyphae and skeleto-ligative hyphae, a feature which tends to make the mushroom tissue hard and woody. There are no cystidia in the hymenium. [10] The fungus has been shown to produce asexual spores when grown in pure culture conditions. [11]

Habitat and distribution

Picipes badius is a saprobic species, and causes white rot. [12] It grows on the standing or fallen trunks and branches of various hardwood genera, including Acer , Aesculus , Alnus , Betula , Castanea , Fagus , Fraxinus , Populus , Prunus , Robinia , Quercus , Salix , Tilia and Ulmus . The fungus grows in temperate regions of Asia, Europe, and North America. [10]

In fungi, a basidiocarp, basidiome, or basidioma (pl. basidiomata) is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles.

<i>Daedaleopsis confragosa</i> Species of fungus

Daedaleopsis confragosa, commonly known as the thin walled maze polypore or the blushing bracket, is a species of polypore fungus in the family Polyporaceae. A plant pathogen, it causes a white rot of injured hardwoods, especially willows. The fruit bodies are semicircular and tough, have a concentrically zoned brownish upper surface, and measure up to 20 cm (8 in) in diameter. The whitish underside turns gray-brown as the fruit body ages, but bruises pink or red. It is found all year and is common in northern temperate woodlands of eastern North America, Europe, and Asia. The species was first described from Europe in 1791 as a form of Boletus, and has undergone several changes of genus in its taxonomic history. It acquired its current name when Joseph Schröter transferred it to Daedaleopsis in 1888.

<i>Mycena aurantiomarginata</i> Species of fungus in the family Mycenaceae common in Europe and North America

Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. First formally described in 1803, it was given its current name in 1872. Widely distributed, it is common in Europe and North America, and has also been collected in North Africa, Central America, and Japan. The fungus is saprobic, and produces fruit bodies (mushrooms) that grow on the floor of coniferous forests. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges. A microscopic characteristic is the club-shaped cystidia that are covered with numerous spiky projections, resembling a mace. The edibility of the mushroom has not been determined. M. aurantiomarginata can be distinguished from similar Mycena species by differences in size, color, and substrate. A 2010 publication reported the discovery and characterization of a novel pigment named mycenaaurin A, isolated from the mushroom. The pigment is responsible for its color, and it has antibiotic activity that may function to prevent certain bacteria from growing on the mushroom.

<i>Hapalopilus rutilans</i> Species of fungus

Hapalopilus rutilans is a species of polypore fungus in the family Polyporaceae. Officially described in 1821, it was transferred to its current genus Hapalopilus six decades later. It is commonly known as the tender nesting polypore, purple dye polypore, or the cinnamon bracket. This widely distributed species is found on five continents. It grows on the fallen or standing dead wood of deciduous trees, in which it fruits singly, in groups, fused, or in overlapping clusters. Fruit bodies are in the form of kidney-shaped to semicircular, cinnamon-orange-brown brackets. The underside of the fruit body features a yellowish to brownish pore surface with tiny angular pores, from which spores are released.

<i>Pycnoporellus alboluteus</i> Species of fungus

Pycnoporellus alboluteus, commonly known as the orange sponge polypore, is a species of polypore fungus in the family Fomitopsidaceae. Distributed throughout the boreal conifer zone, the fungus is found in mountainous regions of western North America, and in Europe. It causes a brown cubical rot of conifer wood, especially spruce, but also fir and poplar. The soft, spongy orange fruit bodies grow spread out on the surface of fallen logs. Mature specimens have tooth-like or jagged pore edges. A snowbank mushroom, P. alboluteus can often be found growing on logs or stumps protruding through melting snow. Although the edibility of the fungus and its usage for human culinary purposes are unknown, several species of beetles use the fungus as a food source.
