Harrya chromapes, commonly known as the yellowfoot bolete or the chrome-footed bolete, is a species of bolete fungus in the family Boletaceae. The bolete is found in eastern North America, Costa Rica, and eastern Asia, where it grows on the ground, in a mycorrhizal association with deciduous and coniferous trees. Fruit bodies have smooth, rose-pink caps that are initially convex before flattening out. The pores on the cap undersurface are white, aging to a pale pink as the spores mature. The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base. The mushrooms are edible but are popular with insects, and so they are often infested with maggots.

Contents

In its taxonomic history, Harrya chromapes has been shuffled to several different genera, including Boletus , Leccinum , and Tylopilus , and is known in field guides as a member of one of these genera. In 2012, it was transferred to the newly created genus Harrya when it was established that morphological and molecular evidence demonstrated its distinctness from the genera in which it had formerly been placed.

Taxonomy

The species was first described scientifically by American mycologist Charles Christopher Frost as Boletus chromapes. Cataloging the bolete fungi of New England, Frost published 22 new bolete species in that 1874 publication. [2] Rolf Singer placed the species in Leccinum in 1947 due to the scabrous dots on the stipe, [3] even though the spore print color was not typical of that genus. In 1968, Alexander H. Smith and Harry Delbert Thiers thought that Tylopilus was a more appropriate fit as they believed the pinkish-brown spore print—characteristic of that genus—to be of greater taxonomic significance. [4] Other genera to which it has been shuffled in its taxonomic history include Ceriomyces by William Alphonso Murrill in 1909, [5] and Krombholzia by Rolf Singer in 1942; [6] Ceriomyces and Krombholzia have since been subsumed into Boletus and Leccinum, respectively. [7] Additional synonyms include Tylopilus cartagoensis, described by Wolfe & Bougher in 1993, [8] and a later combination based on this name, Leccinum cartagoense. [9]

Molecular analysis of large-subunit ribosomal DNA and translation elongation factor 1α showed that the species belonged to a unique lineage in the family Boletaceae, and the genus Harrya was circumscribed to contain both it (as the type species) and the newly described H. atriceps . Javan species referred to Tylopilus pernanus are sister to the Harrya lineage. [1]

The specific epithet chromapes is Latin for "yellow foot". [10] It is commonly known as the "yellowfoot bolete" [11] or the "chrome-footed bolete". [12]

Description

Harrya chromapes 279859.jpg
The stipe base is chrome yellow.
Harrya chromapes 279857.jpg
The stipe surface has pink or reddish scabers.

The fruit bodies have caps that are initially convex before flattening out in maturity, reaching diameters between 3 and 15 cm (1.2 and 5.9 in). The cap surface is dry to slightly sticky. It is initially pink to rose-colored, fading to tan or pinkish tan in maturity. [12] The cap margin may curl upward in maturity. [13] The flesh is white, and does not stain blue when it is bruised or injured (an important diagnostic feature of many bolete species). It does not have any distinct odor or taste. The pore surface is initially white before becoming pinkish to flesh-colored in age. The individual pores are circular to angular, numbering two or three per millimeter, while the tubes are 8–14 mm (0.3–0.6 in) long. [12] Tubes near the top of the stipe are depressed and almost free from attachment. [14] The stipe measures 4–14 cm (1.6–5.5 in) long by 1–2.5 cm (0.4–1.0 in) thick and is equal in width throughout its length, or with a slight taper in either direction. The stipe surface has a scurfy texture from scabers that are colored white, pink or reddish. The underlying surface color is white or pinkish except for the yellow base. [12] The mushrooms are edible and good, but popular with insects, and so are often infested with maggots. [15]

Spores are smooth and translucent, measuring up to 17 mm long Harrya chromapes 223007.jpg
Spores are smooth and translucent, measuring up to 17 μm long

The spore print has been reported as ranging in color from pinkish, to pinkish-brown, [12] to rosy brown, to vinaceous-fawn. The variation in spore print color results in part from differences in moisture content when recorded. [16] Spores are roughly oblong to oval, smooth, hyaline (translucent) to pale brown, and measure 11–17 by 4–5.5  μm. [12] They are covered in a gelatinous sheath. [16] The basidia (spore-bearing cells) are club-shaped, two- and four-spored, thin-walled, and measure 25–35 by 10–14 μm. Pleurocystidia (found on the tube walls) are roughly cylindrical to fuse-shaped with rounded tips, and measure 37–50 by 5–8 μm. Cheilocystidia (on the tube edges) are fuse-shaped with a central swelling, thin-walled, and measure 23–40 by 6–8 μm. Caulocystidia at the top of the stipe have various shapes and dimensions of 25–45 by 10–15 μm; at the stipe base, the caulocystidia are 30–40 by 7–23 μm and are mostly club-shaped to roughly spherical to tear-shaped. The cap cuticle comprises a single layer of tangled hyphae that are 4–6 μm thick. [17]

Several chemical tests can be used to confirm the identify of the mushroom. A drop of ferrous sulfate (FeSO4) on the flesh turns it greenish, while potassium hydroxide (KOH) turns it brown. The cap cuticle turns yellow with nitric acid (HNO3), and yellow with ammonium hydroxide (NH4OH). [17]

Similar species

Fruit bodies of Harrya chromapes are readily identified in the field by their rosy color, bright yellow stipe base, and reddish scabers on the stipe. Tylopilus subchromapes is a similar species found in Australia. [8] Tylopilus ballouii has a more orangish cap and lacks the distinctive chrome-yellow stipe base. [13] Harrya atriceps is a closely related rare species from Costa Rica. In contrast to its more common relative, it lacks reddish color in its stipe scabers and has a black cap, although it has a similar yellow stipe base. [1]

Habitat and distribution

Harrya chromapes is an ectomycorrhizal species, [18] and its fruit bodies grow singly to scattered on soil. They are usually found in forests containing conifers, Betulaceae and oak in North America. The North American distribution includes eastern Canada south to Georgia and Alabama, [1] including Mexico. [19] It extends west to Michigan and Mississippi. [1] The fruit season extends from late spring to late summer. [13] In Costa Rica, where the species associates with oak, it has been recorded from the Cordillera Talamanca, the Poás and Irazu Volcano. [1] It is also in Guatemala. [20] In Asia, it is known from India (West Bengal), [21] Taiwan, [22] Japan, [23] and in China, where it associates with trees from the beech and pine families. [1]

Fruit bodies can be parasitized by the molds Sepedonium ampullosporum , S. laevigatum , and S. chalcipori . In Sepedonium infections, a white to powdery yellow mold covers the surface of the fruit body. [24] The mushrooms are a food source and rearing habitat for several insect species, including the fungus gnats Mycetophila fisherae and M. signatoides , and flies such as Pegomya winthemi and species of the genera Sciophila and Mydaea . [25] The cottontail rabbit species Sylvilagus brasiliensis has been recorded feeding on the mushrooms in Costa Rica. [26]

<span class="mw-page-title-main">Boletaceae</span> Family of fungi

The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.

<i>Leccinum</i> Genus of fungi

Leccinum is a genus of fungi in the family Boletaceae. It was the name given first to a series of fungi within the genus Boletus, then erected as a new genus last century. Their main distinguishing feature is the small, rigid projections (scabers) that give a rough texture to their stalks. The genus name was coined from the Italian Leccino, for a type of rough-stemmed bolete. The genus has a widespread distribution, especially in north temperate regions, and contains about 75 species.

<i>Caloboletus calopus</i> Species of fungus in the family Boletaceae found in Asia, Northern Europe and North America

Caloboletus calopus, commonly known as the bitter bolete, bitter beech bolete or scarlet-stemmed bolete, is a fungus of the bolete family, found in Asia, Northern Europe and North America. Appearing in coniferous and deciduous woodland in summer and autumn, the stout fruit bodies are attractively coloured, with a beige to olive cap up to 15 cm (6 in) across, yellow pores, and a reddish stipe up to 15 cm (6 in) long and 5 cm (2 in) wide. The pale yellow flesh stains blue when broken or bruised.

<i>Tylopilus</i> Genus of fungi

Tylopilus is a genus of over 100 species of mycorrhizal bolete fungi separated from Boletus. Its best known member is the bitter bolete, the only species found in Europe. More species are found in North America, such as the edible species T. alboater. Australia is another continent where many species are found. All members of the genus form mycorrhizal relationships with trees. Members of the genus are distinguished by their pinkish pore surfaces.

<i>Tylopilus felleus</i> Species of fungus

Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff or tan and typically measure up to 15 cm (6 in) in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring and it may be distinguished from Boletus edulis and other similar species by its unusual pink pores and the prominent dark-brown net-like pattern on its stalk.

<i>Bothia</i> Genus of fungi

Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of B. castanella to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.

<i>Exsudoporus frostii</i> Species of fungus in the family Boletaceae found in North America

Exsudoporus frostii, commonly known as Frost's bolete or the apple bolete, is a bolete fungus first described scientifically in 1874. A member of the family Boletaceae, the mushrooms produced by the fungus have tubes and pores instead of gills on the underside of their caps. Exsudoporus frostii is distributed in the eastern United States from Maine to Georgia, and in the southwest from Arizona extending south to Mexico and Costa Rica. A mycorrhizal species, its fruit bodies are typically found growing near hardwood trees, especially oak.

<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 trees, suggesting a saprobic lifestyle. Despite the occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms a close association with the tree's roots.

<i>Leccinum manzanitae</i> Species of fungus

Leccinum manzanitae is an edible species of bolete fungus in the family Boletaceae. Described as new to science in 1971, it is commonly known as the manzanita bolete for its usual mycorrhizal association with manzanita trees. Its fruit bodies (mushrooms) have sticky reddish to brown caps up to 20 cm (8 in), and its stipes are up to 16 cm (6.3 in) long and 3.5 cm (1.4 in) thick. They have a whitish background color punctuated with small black scales known as scabers. Found only in the Pacific Northwest region of the United States and Canada, it is the most common Leccinum species in California. The mushroom is edible, although opinions vary as to its quality. L. manzanitae can be usually distinguished from other similar bolete mushrooms by its large size, reddish cap, dark scabers on a whitish stipe, and association with manzanita and madrone.
