Phylloporus rhodoxanthus, commonly known as the gilled bolete, [1] is a species of fungus in the family Boletaceae. Like other species in the genus, it has a lamellate (gilled) hymenium and forms a mycorrhizal association with the roots of living trees, specifically beech and oak in North and Central America.

Taxonomy

The species was first described from North Carolina as Agaricus rhodoxanthus by Lewis David de Schweinitz in 1822. [2] Giacomo Bresadola transferred it to Phylloporus in 1900. [3]

Description

The deep yellow gills are well spaced. Phylloporus rhodoxanthus 50674.jpg
The deep yellow gills are well spaced.

The cap is initially convex before flattening out in age, sometimes developing a central depression; it attains a diameter of 4–10 cm (1.6–3.9 in). The cap margin is initially curved inward. The cap surface is dry, with a somewhat velvet-like texture, and often develops cracks in maturity that reveal the pale yellow flesh underneath. Its color ranges from dull red to reddish brown, to reddish yellow, or olive brown. The flesh has no distinct taste or odor. The gills are decurrent to somewhat decurrent, and well-spaced. They are deep yellow to greenish-yellow, often wrinkled, and usually have cross-veins in the spaces between the gills; these cross-veins sometimes give the gills a somewhat pore-like appearance. The cylindrical stem measures 4–7.5 cm (1.6–3.0 in) long by 7.5 cm (3.0 in) thick, and is often tapered toward the base. The stem is firm and solid (i.e., not hollow), and yellow, with yellow mycelium at the base. It frequently has longitudinal grooves extending down from the gills. [4]

Phylloporus rhodoxanthus produces an olivaecous yellow-brown spore print. Spores are elliptical to spindle-shaped, smooth, and measure 9–14 by 3.5–5  μm. [4]

Similar species

In North America, Phylloporus rhodoxanthus can be confused with: P. leucomycelinus , distinguished by the presence of white mycelium at the base of its stem; P. arenicola , associated with pines in western North America; P. boletinoides , present in southern North America and having a subporoid, olive-yellow hymenium; and P. foliiporus , also present in southern North America and microscopically distinguished by the presence of cystidia.

Fruit bodies are edible and considered good by some. [6] [7] The flavor has been described as "tender and nutty", and drying the fruit bodies first enhances the flavor. Suitable culinary uses include sauteing, adding to sauces or stuffings, or raw as a colorful garnish. [7] They are also used by hobbyists to make mushroom dyes of beige, greenish beige, or gold colors, depending on the mordant used. [8]

Habitat and distribution

The fruit bodies of Phylloporus rhodoxanthus grow on the ground singly or in small groups in deciduous forests of oak and beech. [5] The species has a wide distribution in North America, where it fruits from July to October, [9] and has also been reported from Belize. [5] The name was formerly applied to Phylloporus species from Asia (China, [10] India, [11] and Taiwan), [12] Australia, [13] and Europe, [14] but more recent research has shown that these non-American records refer to different species.

<i>Xerocomus subtomentosus</i> Species of fungus

Xerocomus subtomentosus, commonly known as suede bolete, brown and yellow bolete , boring brown bolete or yellow-cracked bolete, is a species of bolete fungus in the family Boletaceae. The fungus was initially described by Carl Linnaeus in 1753 and known for many years as Boletus subtomentosus. It is edible, though not as highly regarded as other bolete mushrooms.

<i>Aureoboletus mirabilis</i> Species of fungus

Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the Boletaceae mushroom family. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots.

<i>Xerocomellus zelleri</i> Species of fungus

Xerocomellus zelleri, commonly known as Zeller's bolete, is an edible species of mushroom in the family Boletaceae. First described scientifically by American mycologist William Alphonso Murrill in 1912, the species has been juggled by various authors to several genera, including Boletus, Boletellus, and Xerocomus. Found solely in western North America from British Columbia south to Mexico, the fruit bodies are distinguished by their dark reddish brown to nearly black caps with uneven surfaces, the yellow pores on the underside of the caps, and the red-streaked yellow stems. The fungus grows in summer and autumn on the ground, often in Douglas fir forests or on their margins. The development of the fruit bodies is gymnocarpic, meaning that the hymenium appears and develops to maturity in an exposed state, not enclosed by any protective membrane.

<i>Cantharellus lateritius</i> Species of fungus

Cantharellus lateritius, commonly known as the smooth chanterelle, is a species of edible fungus in the mushroom family Cantharellaceae. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface (hymenium) of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of C. lateritius is much smoother.

<i>Caloboletus rubripes</i> Species of fungus

Caloboletus rubripes, commonly known as the red-stipe bolete or the red-stemmed bitter bolete, is a mushroom in the family Boletaceae. It was known as Boletus rubripes until 2014. Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged. and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.

<i>Suillus pungens</i> Species of fungus in the family Suillaceae found in California

Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.

<i>Collybia cookei</i> Species of fungus

Collybia cookei is a species of fungus in the family Tricholomataceae, and one of three species in the genus Collybia. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like Meripilus giganteus, Inonotus hispidus, or species of Russula; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to 9 mm (0.35 in) in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of Collybia unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined.

<i>Hygrophorus purpurascens</i> Species of fungus

Boletus rubroflammeus is a species of bolete fungus in the family Boletaceae. First described from Michigan in 1971, it is found in the eastern United States and Mexico, where it grows in a mycorrhizal association with hardwood trees. The fruit bodies (mushrooms) of the fungus have caps that are deep red to purplish red, and dark red pores. The stem has coarse, dark red reticulations and a narrow yellow area at the top. All parts of the mushroom quickly stain blue when injured or cut. Lookalikes include Boletus flammans, a lighter-colored species that grows with conifers. Other similar species can be distinguished by differences in distribution, morphology, staining reaction, and microscopic characteristics. Boletus rubroflammeus mushrooms are poisonous, and can cause gastrointestinal distress if consumed.
