Tyromyces pulcherrimus, commonly known as the strawberry bracket, is a species of poroid fungus in the family Polyporaceae. It is readily recognisable by its reddish fruit bodies with pores on the cap underside. The fungus is found natively in Australia and New Zealand, where it causes a white rot in living and dead logs of southern beech and eucalyptus. In southern Brazil, it is an introduced species that is associated with imported eucalypts.

Taxonomy

The fungus was first described in 1922 by English-born Australian dentist and botanist Leonard Rodway, who called it Polyporus pulcherrimus. Curtis Gates Lloyd, an American mycologist to whom Rodway had sent a specimen for examination, suggested a similarity to Albatrellus confluens . [2] Gordon Herriot Cunningham transferred it to the genus Tyromyces in 1922 to give it the name by which it is known by today. [3] Some sources refer to the species as Aurantiporus pulcherrimus, after Buchanan and Hood's proposed 1992 transfer to Aurantiporus . [4]

The specific epithet pulcherrimus is derived from the Latin word for "very beautiful". One common name used for the fungus is strawberry bracket. [5]

The fruit bodies of Tyromyces pulcherrimus are bracket-shaped caps that measure 3–8 cm (1.2–3.1 in) in diameter. They are sessile, lacking a stipe, and are instead attached directly to the substrate. The cap colour when fresh is cherry red or salmon, but it dries to become brownish. The cap surface can be hairy, particularly near the point of attachment. Pores on the cap underside are red, and number about 1–3 per millimetre. The flesh is soft and thick, red, and watery. It does not have any distinct odour. [6] Tyromyces pulcherrimus is inedible. [5]

With a monomitic hyphal system, Tyromyces pulcherrimus contains only generative hyphae. These hyphae are clamped, and are sometime covered with granules, or an orange substance that appears oily. The hyphae in the context are arranged in a parallel fashion, and strongly agglutinated to form a densely packed tissue. Cystidia are absent from the hymenium. The basidia are club shaped with typically four sterigmata, and measure 15–23 by 6.5–7.5  μm. Spores are ellipsoid to more or less spherical, hyaline, and measure 5–7 by 3.5–4.5 μm. [4]

Tyromyces pulcherrimus is a white rot fungus that grows on the exposed heartwood of several tree species. It has been recorded on southern beech (Nothofagus cunninghamii) in Victoria and Tasmania and on Antarctic beech (Nothofagus moorei) in Queensland and New South Wales. [6] In Tasmania, evidence suggests that it prefers wet forests, including rainforest and wet sclerophyll forest. [7] In Brazil, it is an introduced species that has been recorded on imported eucalypts. [5] It has been found there in Rio Grande do Sul State. [8] In New Zealand, the fungus has been recorded on red beech (Fuscospora fusca) and silver beech (Lophozonia menziesii). [9]

<i>Cerioporus squamosus</i> Species of fungus

Cerioporus squamosus aka Polyporus squamosus is a basidiomycete bracket fungus, with common names including dryad's saddle and pheasant's back mushroom. It has a widespread distribution, being found in North America, Australia, Asia, and Europe, where it causes a white rot in the heartwood of living and dead hardwood trees. The name "dryad's saddle" refers to creatures in Greek mythology called dryads who could conceivably sit and rest on this mushroom, whereas the pheasant's back analogy derives from the pattern of colors on the bracket matching that of a pheasant's back.

<i>Omphalotus nidiformis</i> Species of bioluminescent fungus in the family Marasmiaceae

Omphalotus nidiformis, or ghost fungus, is a gilled basidiomycete mushroom most notable for its bioluminescent properties. It is known to be found primarily in southern Australia and Tasmania, but was reported from India in 2012 and 2018. The fan or funnel shaped fruit bodies are up to 30 cm (12 in) across, with cream-coloured caps overlain with shades of orange, brown, purple, or bluish-black. The white or cream gills run down the length of the stipe, which is up to 8 cm (3 in) long and tapers in thickness to the base. The fungus is both saprotrophic and parasitic, and its fruit bodies are generally found growing in overlapping clusters on a wide variety of dead or dying trees.

<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>Tyromyces chioneus</i> Species of fungus

Tyromyces chioneus, commonly known as the white cheese polypore, is a species of polypore fungus. A widely distributed fungus, it has a circumpolar distribution, in temperate boreal pine forests, of Asia, Europe, and North America, causes white rot in dead hardwood trees, especially birch.

<i>Meripilus giganteus</i> Species of fungus

Meripilus giganteus is a polypore fungus in the family Meripilaceae. It causes a white rot in various types of broadleaved trees, particularly beech (Fagus), but also Abies, Picea, Pinus, Quercus and Ulmus species. This bracket fungus, commonly known as the giant polypore or black-staining polypore, is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance away from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the northern Hemisphere, and is widely distributed in Europe. In the field, it is recognizable by the large, multi-capped fruiting body, as well as its pore surface that quickly darkens black when bruised or injured.

<i>Suillus lakei</i> Species of fungus

Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the family Suillaceae. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm, while the stems are between 6 and 12 cm long and usually 1–3 cm thick. On the underside of the cap is a layer of spongy yellow to yellow-brown angular pores; these pores are covered with a whitish partial veil when young. A mycorrhizal fungus, S. lakei grows in association with Douglas fir, and is found where this tree occurs. It is native to northwestern North America, but has been introduced to Europe, South America, and New Zealand. The mushroom is edible, but opinions vary considerably as to its quality.

Echinochaete is a genus of fungi in the family Polyporaceae. Circumscribed by English mycologist Derek Reid in 1963, the genus is widespread in tropical regions and contains five species.

<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>Tyromyces</i> Genus of fungi

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."

<i>Amanita australis</i> Species of fungus

Amanita australis is a species of fungus in the family Amanitaceae. It produces small- to medium-sized fruit bodies, with brown caps up to 9 centimetres in diameter covered with pyramidal warts. The gills on the underside of the cap are white, closely crowded together, and free from attachment to the stem. The stem, up to 9 cm long, has a ring and a bulbous base. The mushroom may be confused with another endemic New Zealand species, A. nothofagi, but can be distinguished by differences in microscopic characteristics.

<i>Picipes badius</i> Species of fungus

Picipes 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.
