Strobilomyces glabriceps is a species of bolete fungus in the family Suillaceae found in China. It was described as new to science in 1948 by Wei-Fan Chiu. The type collection was made in Kunming in June, 1938.
Fruit bodies have convex brown caps measuring up to 10 cm (3.9 in) in diameter. The surface is initially smooth, but becomes cracked as the bolete ages. Tubes on the cap underside are 2–2.5 cm (0.8–1.0 in) long, while the large angular pores are 4–5 mm across. Spores are spherical or nearly so, and measure 9–11 µm. [1]
Strobilomyces glabriceps is characterized by its medium to large basidiomes (90–150 mm diameter), a nearly smooth, convex pileus that is 10 cm in diameter and "Carob Brown" in color, featuring gray-black, sizable, patch-like or pressed scales (5–14 mm diameter) or fine filaments. The stipe is 12 cm long, 15–30 mm thick, and "Russet Brown" with streaks and furfuraceous texture, usually tapering towards the base and slightly bulbous at the end. A cottony ring is present at the stipe's apex, with gray to dirty white and gray-black thin fluffy filaments on the upper and lower parts. The fungus has large hymenophoral pores (1–3 mm diameter) that are "Mikado Brown," decurrent on the stipe, angular or comb-like, and gray-black discolored upon exposure. The spores are dark brown under the microscope, globose to subglobose, reticulate, measuring 9-12(11) μm, with medium-sized meshes (2-4 μm diameter; Chiu 1948). [2]
The phylogeny of the genus Strobilomyces is recently being revised, and 49 phylogenetic species are being revealed in which 26 are potentially new species (Han et al. 2018). [3] Phylogenetically, S. glabriceps is closely related to S. pteroreticulosporus and they fall into a clade that shares reticulate basidiospore mash (Han et al. 2020). [4] Nevertheless, S. pteroreticulosporus stands out due to its petite, upright, conical scales (1–3 mm in height and 1–3 mm in diameter at the base) on the cap, a rusty red hue when exposed, and it is observed to found in forest dominated by Pinus spp. (Antonín 2015). [5]
Based on morphological analysis, S. glabriceps is similar to S. glabellus J.Z. Ying and S. latirimosus J.Z. Ying, two species native to Yunnan China; but it from the letters in having decurrent tubes, and larger spores that 9-12μm in diameter (Ying & Ma, 1985). [6]
Species of Strobilomyces sect. Strobilomyces typically develop ectomycorrhizal connections with plants of families such as Dipterocarpaceae, Myrtaceae, Casuarinaceae, Fagaceae, and Pinaceae (Sato et al. 2017, Han et al. 2018), [7] [3] but specific mycorrhizal relationship has yet been observed on S. glabriceps.
Subtropical regions of China, Japan, and India, and it can be found either alone or in small groups (Han et al. 2020). [4] A specimen is also identified from Kon Tum Plateau, Vietnam (Giang & Alexandrova 2021). [8] The type specimen of S. glabriceps was collected in Kunming, China, in June 7, 1938 (Chiu 1948). [2]
Forest dominated by Fagaceae trees or mixed forests of Fagaceae and Pinaceae are the most common habitats for this species (Han et al. 2020). [4]
This is an edible species in China, and it sometimes sold in market (Wang et al. 2004), [9] especially in Yunnan Province. This species is known as "光盖松塔牛肝菌" in Chinese (Dai et al. 2010). [10] Yu & Liu (2005) [11] believed that Yunnan pine (Pinus yunnanensis) forest, one of the habitats of S. glabriceps, was being destroyed, and with the commercialization, local people often over-collected edible fungi, so many edible fungi were being vulnerable or endangered. risk; however, the extent of the threat to this species has not been assessed.
Strobilomyces is a genus of boletes. The only well-known European species is the type species S. strobilaceus, known in English as "old man of the woods".
Suillus is a genus of basidiomycete fungi in the family Suillaceae and order Boletales. Species in the genus are associated with trees in the pine family (Pinaceae), and are mostly distributed in temperate locations in the Northern Hemisphere, although some species have been introduced to the Southern Hemisphere.
Suillus luteus is a bolete fungus, and the type species of the genus Suillus. A common fungus native all across Eurasia from Ireland to Korea, it has been introduced widely elsewhere, including North and South America, southern Africa, Australia and New Zealand. Commonly referred to as slippery jack or sticky bun in English-speaking countries, its names refer to the brown cap, which is characteristically slimy in wet conditions. The fungus, initially described as Boletus luteus by Carl Linnaeus in 1753, is now classified in a different fungus family as well as genus. Suillus luteus is edible, though not as highly regarded as other bolete mushrooms. It is commonly prepared and eaten in soups, stews or fried dishes. The slime coating, however, may cause indigestion if not removed before eating. It is often sold as a dried mushroom.
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.
Suillus bovinus, also known as the Jersey cow mushroom or bovine bolete, is a pored mushroom of the genus Suillus in the family Suillaceae. A common fungus native to Europe and Asia, it has been introduced to North America and Australia. It was initially described as Boletus bovinus by Carl Linnaeus in 1753, and given its current binomial name by Henri François Anne de Roussel in 1806. It is an edible mushroom, though not highly regarded.
Boletellus obscurecoccineus, known as the rhubarb bolete, is a species of fungus in the family Boletaceae, found in Australia, New Guinea, Java, Borneo, Japan, Korea, and Taiwan. It is a distinctive and colourful bolete of the forest floor.
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.
Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm, while the stipe is up to 6 cm long and 2 cm thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.
Suillus spraguei is a species of fungus in the family Suillaceae. It is known by a variety of common names, including the painted slipperycap, the painted suillus or the red and yellow suillus. Suillus spraguei has had a complex taxonomical history, and is also frequently referred to as Suillus pictus in the literature. The readily identifiable fruit bodies have caps that are dark red when fresh, dry to the touch, and covered with mats of hairs and scales that are separated by yellow cracks. On the underside of the cap are small, yellow, angular pores that become brownish as the mushroom ages. The stalk bears a grayish cottony ring, and is typically covered with soft hairs or scales.
Suillellus amygdalinus is a fungus of the bolete family found in western North America. The fruit bodies, or mushrooms, are characterized by their thick, red to brown caps, red pores, and the strong bluing reaction observed when the mushroom tissue is injured or cut. The cap can reach diameters of up to 12 cm (4.7 in) and the stipe 9 cm (3.5 in) long by 3 cm (1.2 in) thick at maturity. This mushroom has been found in manzanita and madrone woodlands of central California north to southern Oregon. Although the edibility of the mushroom is not known with certainty, it may be poisonous, and is not recommended for consumption. Other similar red-pored, bluing boletes from North America, including Rubroboletus eastwoodiae, Boletus luridiformis, and B. subvelutipes, can be distinguished from S. amygdalinus either by the color of the cap, the degree of reticulation on the stipe, or by location.
Hypomyces chrysospermus, the bolete eater, is a parasitic ascomycete fungus that grows on bolete mushrooms, turning the afflicted host a whitish, golden yellow, or tan color. It is found in Eurasia and North America, as well as southwest Western Australia.
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.
Butyriboletus regius, commonly known as the royal bolete or red-capped butter bolete, is a basidiomycete fungus of the genus Butyriboletus found in China and Europe. B. regius has a pink cap, yellow flesh, and a reticulate pattern on the stem. Harry D. Thiers described a similar mushroom from California as B. regius, though it is not the same species. B. regius in Europe does not stain when exposed to air, or stains weakly, but the California species stains blue. Both European and California species are considered choice edibles.
Tylopilus virens is a bolete fungus in the family Boletaceae found in Asia. It was described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; Japanese mycologist Tsuguo Hongo transferred it to Tylopilus in 1964. The fruit body has a convex to flattened cap that is 2.5–8 cm (1.0–3.1 in) in diameter. The tubes on the cap underside are up to 2 cm long, while the roundish pores are about 1–2 mm wide. The mushroom is similar in appearance to Tylopilus felleus, but unlike that species, has a greenish cap when young. T. virens typically grows near the conifer species Keteleeria evelyniana. It has elliptical spores measuring 11–14 by 5.5–6 µm.
Tylopilus albofarinaceus is a bolete fungus in the family Boletaceae found in China. It was first described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; F.L. Tai transferred it to the genus Tylopilus in 1979. The fruit body has a convex, white cap that is up to 5 cm (2 in) in diameter. The tubes on the cap underside are 3 mm long, while the pores are about 0.7–1 mm wide. The flesh in the stipe is white and does not change color with injury. It has ellipsoid spores measuring 11–14 by 5–7 µm. The type collection was made in Kunming in August 1938.
Tylopilus punctatofumosus is a bolete fungus in the family Boletaceae found in China. It was described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; F.L. Tai transferred it to the genus Tylopilus in 1979. The fruit body has a hemispherical to cushion-shaped, white cap measuring 2–3.5 cm (0.8–1.4 in) in diameter. The pores on the cap underside measure less than 1 mm wide. The flesh in the stipe is whitish to yellowish at the base, and does not change color with injury. It has ellipsoid spores measuring 9–11 by 5–6 µm. The type collection was made in Chichushan, in September 1938 growing under the conifer species Chinese white pine. Related Asian Tylopilus species include T. javanicus and T. roseolus.
Rubroboletus sinicus is a bolete fungus in the family Boletaceae. It is found in China. The species was first described by Wei Fan Chiu as Boletus sinicus in 1948, and transferred to the genus Tylopilus in 1979 by Fanglan Tai. In 2014, the genus Rubroboletus was created to accommodate this and allied species.
Leccinellum rugosiceps, commonly known as the wrinkled Leccinum, is a species of bolete fungus. It is found in Asia, North America, Central America, and South America, where it grows in an ectomycorrhizal association with oak. Fruitbodies have convex, yellowish caps up to 15 cm (5.9 in) in diameter. In age, the cap surface becomes wrinkled, often revealing white cracks. The stipe is up to 10 cm (3.9 in) long and 3 cm (1.2 in) wide, with brown scabers on an underlying yellowish surface. It has firm flesh that stains initially pinkish to reddish and then to grayish or blackish when injured. The pore surface on the cap underside is yellowish. Fruitbodies are edible, although opinions vary as to their desirability.
Imleria badia, commonly known as the bay bolete, is an edible, pored mushroom found in Eurasia and North America, where it grows in coniferous or mixed woods on the ground or on decaying tree stumps, sometimes in prolific numbers. Both the common and scientific names refer to the bay- or chestnut-coloured cap, which is almost spherical in young specimens before broadening and flattening out to a diameter up to 15 cm (6 in). On the cap underside are small yellowish pores that turn dull blue-grey when bruised. The smooth, cylindrical stipe, measuring 4–9 cm long by 1–2 cm thick, is coloured like the cap, but paler. Some varieties have been described from eastern North America, differing from the main type in both macroscopic and microscopic morphology.
Chroogomphus ochraceus is a species of fungus from the family Gomphidiaceae. Known for its close association with conifer trees–especially pines, it is often referred to as the "pine spike" or "spike cap" fungus. C. ochraceus was originally identified as a species limited to the Pacific Northwest because of its display of distinct yellowish colors, but recent research has concluded that this species is widespread across North America and that it is genetically distinct from Chroogomphus rutilus, which is limited to Europe.
