Fungi named in 2015

Hortiboletus rubellus, commonly known as the ruby bolete, is a small, dainty, brightly coloured member of the family Boletaceae, with a reddish cap and stipe, and yellow pores. Like many boletes, it stains blue when cut or bruised. It is found in deciduous woodland in autumn. There is some question over its edibility, and it is reportedly of poor quality with a taste of soap. Until 2015, the species was known as Boletus rubellus.

Rubroboletus lupinus, commonly known as the wolf bolete, is a bolete fungus of the genus Rubroboletus. Originally described by Elias Magnus Fries in 1838 as species of Boletus, it was transferred to Rubroboletus in 2015, a genus circumscribed to host other allied reddish-colored, blue-staining bolete species forming a distinct clade. The species epithet is derived from the Latin word lupus, meaning "wolf". Molecular studies have revealed considerable genetic variation among European populations of R. lupinus, placing it in a clade sister to Rubroboletus dupainii. The species is found in warm

Rubroboletus legaliae, previously known as Boletus splendidus, B. satanoides, and B. legaliae is a basidiomycete fungus of the family Boletaceae. It is poisonous, with predominantly gastrointestinal symptoms, and is related to Rubroboletus satanas. It's uncommon in Southern England, and Europe, and grows with oak (Quercus) and beech (Fagus) often on neutral to acid soils. It is considered vulnerable in the Czech Republic. In Britain, all of the boletes in the Satanas group are either very rare, endangered, or extinct.

Imperator torosus, commonly known as the brawny bolete, is a species of bolete fungus in the family Boletaceae. It is native to southern Europe east to the Caucasus and Israel. It is generally associated with deciduous trees such as hornbeam, oak and beech in warm, dry locales. Although generally rare in Europe, it appears to be relatively common in Hungary. Appearing in summer and autumn on chalky soils, the stocky fruit bodies have an ochre cap up to 20 cm (8 in) across, yellow pores on the cap underside, and a wine-red to brown or blackish stipe up to 6–15 cm (2.4–5.9 in) long by 3–6 cm

Lanmaoa fragrans is a rare species of bolete fungus in the family Boletaceae found in Europe. It has a brownish convex cap measuring 5–12 cm (2.0–4.7 in) in diameter that initially has a velvety texture before becoming smooth. The spindle-shaped stipe measures 7–9 cm (2.8–3.5 in) long by 3–5 cm (1.2–2.0 in) wide. It is yellow at the top and flushed with red in the lower portions, terminating with black at the very base. The yellow flesh is tinged with red under the cap cuticle. It bruises blue only after several hours of exposure to air. The pores on the cap underside are lemon-yellow to

The oldrose bolete, Imperator rhodopurpureus, is an inedible fungus of the genus Imperator, found under deciduous trees including oak and beech in neutral soils. Initially described as Boletus rhodopurpureus, it was transferred to the new genus Imperator in 2015. The bolete is considered critically endangered in the Czech Republic and endangered in the United Kingdom, reported most commonly from Berkshire and Hampshire, and typically very rare throughout, although up to a hundred fruiting bodies have been recorded at a few sites.

Aureoboletus projectellus is a species of bolete fungus in the family Boletaceae. Found in North America, and recently in Europe, it grows in a mycorrhizal association with pine trees.

Imperator is a genus of fungi in the family Boletaceae. It was circumscribed in 2015 by Boris Assyov and colleagues. The erection of Imperator follows recent molecular phylogenetic studies that outlined a new taxonomic framework for the Boletaceae. The type species is Imperator torosus, an "impressive and prestigious" species to which the generic name Imperator refers. All members of this genus are either toxic if consumed (causing gastroenteritis) or are of unknown edibility.

Geoglossum cookeanum is a mushroom in the family Geoglossaceae, commonly referred to as an "earth tongue" fungus. It is a member of the division Ascomycota, known for its dark, elongated, club-like fruiting body. Geoglossum cookeanum is found in nutrient-poor soils and plays an important role in ecosystem processes, particularly in decomposing organic material (Minter & Cannon, 2015).

Rheubarbariboletus armeniacus is a small mushroom in the family Boletaceae native to Europe. It was formerly placed in the genera Boletus, Xerocomus, and Xerocomellus. It acquired its current name when it was transferred to genus Rheubarbariboletus in 2015.

Hortiboletus bubalinus is a species of bolete fungus in the family Boletaceae. Originally described in 1991 as a species of Boletus, the fungus was transferred to Xerocomus in 1993. It was transferred to Hortiboletus by Bálint Dima in 2015.

Hortiboletus is a genus of fungi in the family Boletaceae. It was circumscribed in 2015 by Giampaolo Simonini, Alfredo Vizzini, and Matteo Gelardi. The erection of Hortiboletus follows recent molecular studies that outlined a new phylogenetic framework for the Boletaceae. Hortiboletus is derived from the Latin word hortus "garden", referring to a typical habitat of the type species, Hortiboletus rubellus. The bolete H. bubalinus, originally described as a Boletus and later placed in Xerocomus, was transferred to the genus by Bálint Dima. In 2015, Alona Yu. Biketova transferred Boletus

Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is a species of fungus in the Boletaceae mushroom family. The fruit body has 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

Suillellus caucasicus is a species of bolete fungus in the family Boletaceae. It was first described as a variety of Boletus luridus in 1947 by Rolf Singer, then as an independent species by Singer in 1966. The name change in the latter publication was invalid, so Carlo Luciano Alessio published the new combination validly in 1985.

Lanmaoa is a fungal genus in the family Boletaceae. It was circumscribed by Chinese mycologists Nian-Kai Zeng and Zhu L. Yang in 2015 to contain several species formerly classified in the genus Boletus (L. carminipes, L. flavorubra, L. pseudosensibilis), as well as the newly described Asian boletes L. angustispora and L. asiatica. The erection of this genus follows recent molecular studies that outlined a new phylogenetic framework for the family Boletaceae. Zeng and Yang named the genus after Chinese naturalist Lan Mao (1397-1476).

Baorangia bicolor, also known as the two-colored bolete or red and yellow bolete after its two-tone coloring scheme, is a species of fungus in the genus Baorangia. Its fruit body, the mushroom, is classed as medium or large in size, which helps distinguish it from the many similar appearing species that have a smaller stature. A deep blue/indigo bruising of the pore surface and a less dramatic bruising coloration change in the stem over a period of several minutes are identifying characteristics that distinguish it from the similar poisonous species Boletus sensibilis. There are also

Rheubarbariboletus is a fungal genus in the family Boletaceae. Circumscribed in 2014, it contains two species found in Europe: Rheubarbariboletus persicolor, and the type, R. armeniacus. The generic name is derived from the Latin rheubarbarum, meaning "rhubarb", referring to the color of the flesh at the base of the stipe. The genus is closely related to Xerocomellus, but differs by having smooth spores, the unchanging yellowish to orange-rhubarb coloring of the stipe base, and the distinctive dark-green to black color reaction with iron sulphate on both the surface of the cap and on the

Leucocybe is a small mushroom genus, consisting of 3 named species that were formerly placed in the genus Clitocybe, which they resemble in overall appearance and morphology. They occur in woodlands growing on tree litter or disturbed ground.

Imperator luteocupreus is a species of bolete fungus in the family Boletaceae. It is native to southern Europe, where it is found under chestnut (Castanea) and oak (Quercus). Although it was originally described in genus Boletus, it was placed in the new genus Imperator in 2015, based on phylogenetic inferences.

Baorangia is a fungal genus in the family Boletaceae. It was circumscribed by Chinese mycologists Gang Wu and Zhu L. Yang in 2015 with B. pseudocalopus (formerly classified in Boletus) as the type species. Baorangia emilei and B. bicolor were transferred to the genus from Boletus that same year. The erection of Baorangia follows recent molecular studies that outlined a new phylogenetic framework for the Boletaceae. The generic name—derived from the Chinese words bao ("thin") and rang ("hymenium")—refers to the characteristically thin hymenophore, which distinguishes it from all other

Tropicoporus is a genus of fungi in the family Hymenochaetaceae. It was circumscribed in 2015 with Tropicoporus excentrodendri as the type species, and six additional species transferred from Inonotus.

Exsudoporus permagnificus is a species of bolete fungus in the family Boletaceae, native to Southern Europe and Western Asia (Cyprus and Israel). Described as new to science in 1981, the fungus was originally placed in genus Boletus. Following molecular studies outlining a new phylogenetic framework for Boletaceae, the fungus was transferred to the newly erected genus Exsudoporus in 2014, to which it is the type species. Nevertheless, Wu and colleagues (2016) were reluctant to accept the newly proposed genus due to a lack of sufficient sequences and regarded it a synonym of Butyriboletus.

Sagaranella is a mushroom genus in the family Lyophyllaceae that has been segregated from both Lyophyllum and Tephrocybe using molecular analyses. The species resemble grey colored Collybias and grow in nitrogen-rich environments.

Rhizocybe is a genus of fungus in the order Agaricales. The species resemble Clitocybe and grow amongst litter in predominantly coniferous forests.

Myochromella is a mushroom genus in the family Lyophyllaceae that has been segregated from both Lyophyllum and Tephrocybe using molecular analyses and was first informally labelled clade 'mycochromella' or section 'Tephrophana p.p.' before being recognized as a genus. The species resemble grey colored Collybias and grow in forests.
