Boletinellus monticola, previously known as Gyrodon monticola, is a bolete fungus in the Boletinellaceae family with a pored hymenium rather than gills. [1] This species can be identified by its common ectomycorrhizal association and therefore close proximity to Alder trees (Alnus acuminata). B. monticola is most commonly found near the equator, specifically in Southern Mexico and stretching into northern South America.
Originally, B. monticola was associated with the Gryodon genus by Rolf Singer in 1957. [2] However, it was reassigned to the Boletinellus genus due to its closer genetic relation. [3] This reassignment was reinforced by R. Watling in 1997 who analyzed the description of Rolf Singer's observations in Argentina and concluded it to be related closer to the Boletinellus genus. This change in taxonomy also included the change of Gyrodon exiguus and Gyrodon rompelii to the Boletinellus genus as well. [4]
Boletinellus monticola has a yellow-brown cap with a yellow or orange fertile layer. The stalk extends a few centimeters from the ground and is commonly brown. The fertile layer is made up of large and yellow pores and tubes. B. monticola is also known to produce brown sclerotia in soil providing the ability for the fungus to survive under extreme environmental conditions. The flesh of the bolete is soft and often moist or even wet due to its favored climate of warm tropical areas. This species also produces highly differentiated rhizomorphs with brown dolipore hyphae. [5] B. monticola bruises blue then fades to reddish brown then to dark brown. [6]
Boletinellus monticola is considered to be likely edible, however there is no record of it being eaten. Boletes are known to be edible and are reasonably safe for human consumption. [7] Some closely related species such as B. merulioides have been known to taste “acidic and unpleasant”, [8] while offering very little nutritional value. [9]
This species is a terrestrial fungi which grows in top-soil. B. monticola is grown in warm tropical climates and in high elevations ranging from 1000 m - 3,800 m above sea level. [10] Due to its ectomycorrhizal association with Alder trees (Alnus acuminata) the fungus is restricted to the range of where these trees grow. Since most Alder trees grow north of the equator and B. monticola is only found in warm tropical climates, the fungus is generally rare due to this small geographical region. More specifically, Alnus acuminata is found in the highlands of Mexico to the Andes mountains. [11] In North America, the fungus can be found in Southern Mexico. [12] Stretching into South America, B. monticola has been found in Argentina, Bolivia, Colombia, Costa Rica, and Ecuador. [13]
Most of the species in the Boletinellus genus are ectomycorrhizal and B. monticola is no exception. This species is known to have an ectomycorrhizal relationship with Alder trees (Alnus acuminata). According to a study by Pablo Alvarado in 2021 this relationship could have evolved independently from a common ancestor of the Paxillaceae family nearly 98 million years ago. [14] Using sulpho-vanillin the root and Hartig net stain reddish, bleach with NH4OH and lactic acid, while no reaction occurs when exposed to 15% KOH, Melzer's reagent and 70% ethanol. [5] As a result of ITS PCR/RFLP analysis, B. monticola is identified molecularly and morphologically as a symbiont of A. acuminata in native Argentinean forests. [5]
Using Internal Transcribed Spacer (ITS), Alejandra Becerra et al. in 2003 identified 895 base pairs in the genome. The genome of B. monticola is what allowed for the reassignment of the species from genus Gyrodon to Boletinellus. [5] The work done by the University of California at Berkeley using PCR (Polymerase Chain Reaction) found the sequences of primers and other codons for specific genes didn't align with other species in the Gyrodon genus. This study found the first atp6 (mitochondrial locus) and cox3 sequences in the order Boletales allowing for the comparison of certain genes changing the distribution of various families under the order. [3] Despite the family Boletinellaceae is in the order Boletales, evidence suggests that the family is more closely related to the order Sclerodermataceae, however there appears to be some species exceptions. [15]
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types.
Boletus edulis is a basidiomycete fungus, and the type species of the genus Boletus. Widely distributed in the Northern Hemisphere across Europe, Asia, and North America, it does not occur naturally in the Southern Hemisphere, although it has been introduced to southern Africa, Australia, New Zealand, and Brazil. Several closely related European mushrooms formerly thought to be varieties or forms of B. edulis have been shown using molecular phylogenetic analysis to be distinct species, and others previously classed as separate species are conspecific with this species. The western North American species commonly known as the California king bolete is a large, darker-coloured variant first formally identified in 2007.
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.
Paxillus involutus, also known as the brown roll-rim or the common roll-rim, is a basidiomycete fungus that is widely distributed across the Northern Hemisphere. It has been inadvertently introduced to Australia, New Zealand, South Africa, and South America, probably transported in soil with European trees. Various shades of brown in colour, the fruit body grows up to 6 cm high and has a funnel-shaped cap up to 12 cm wide with a distinctive inrolled rim and decurrent gills that may be pore-like close to the stipe. Although it has gills, it is more closely related to the pored boletes than to typical gilled mushrooms. It was first described by Pierre Bulliard in 1785, and was given its current binomial name by Elias Magnus Fries in 1838. Genetic testing suggests that Paxillus involutus may be a species complex rather than a single species.
The Paxillaceae are a family of mushroom-forming fungi bearing close affinity to the boletes. Collectively, the family contains nine genera and 78 species. The type genus is Paxillus, containing fungi with decurrent gills, and Gyrodon, which has members with decurrent pores, among others. French mycologist René Maire had erected the family in 1902, placing it between the agarics and boletes and recognizing the groups' similarities with the latter group. Maire's usage of the name was later deemed to be invalid, and the genus authority is attributed to Johannes Paulus Lotsy. Molecular research confirms the relations of Gyrodon, with the decurrent-pored mushroom G. lividus, Paragyrodon, with the type species P. sphaerosporus, and Paxillus as sister groups, together lying near the base of a phylogenetic tree from which the genus Boletus arises. The name Gyrodontaceae, published by Belgian botanist Paul Heinemann in 1951, is considered synonymous with Paxillaceae.
Tapinella atrotomentosa, commonly known as the velvet roll-rim or velvet-footed tap, is a species of fungus in the family Tapinellaceae. Although it has gills, it is a member of the pored mushroom order Boletales. August Batsch described the species in 1783. It has been recorded from Asia, Central America, Europe and North America. Tough and inedible, it grows on tree stumps of conifers. The mushroom contains several compounds that act as deterrents of feeding by insects.
Chroogomphus is a genus of mushrooms commonly known as pine-spikes or spike-caps based on their shape and because they are often found growing in association with pine trees. The genus is distributed throughout the Northern Hemisphere including North America and Eurasia.
Gyrodon lividus, commonly known as the alder bolete, is a pored mushroom bearing close affinity to the genus Paxillus. Although found predominantly in Europe, where it grows in a mycorrhizal association with alder, it has also recorded from China, Japan and California. Fruit bodies are distinguished from other boletes by decurrent bright yellow pores that turn blue-grey on bruising. G. lividus mushrooms are edible.
Sarcodon is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales, known for its almost universal ectomycorrhizal ecology. The genus owes its name to the presence of teeth-like spines on the hymenophore, from ancient Greek; sarco = flesh and odon = tooth. For this reason they are commonly called "tooth fungi", or "Hydnoid fungi".
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.
Phlebopus is a genus of fungi in the family Boletinellaceae. The genus has a widespread distribution in subtropical and pantropical regions, and contains 12 species. The species are saprobic, with some possibly able to form mycorrhizae with exotic trees in certain conditions. It contains the gigantic Phlebopus marginatus, the cap of which can reach 1 m (3.3 ft) in diameter.
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.
Suillus salmonicolor, commonly known as the Slippery Jill, is a fungus in the family Suillaceae of the order Boletales. First described as a member of the genus Boletus in 1874, the species acquired several synonyms, including Suillus pinorigidus and Suillus subluteus, before it was assigned its current binomial name in 1983. It has not been determined with certainty whether S. salmonicolor is distinct from the species S. cothurnatus, described by Rolf Singer in 1945. S. salmonicolor is a mycorrhizal fungus—meaning it forms a symbiotic association with the roots of plants such that both organisms benefit from the exchange of nutrients. This symbiosis occurs with various species of pine, and the fruit bodies of the fungus appear scattered or in groups on the ground near the trees. The fungus is found in North America, Hawaii, Asia, the Caribbean, South Africa, Australia and Central America. It has been introduced to several of those locations via transplanted trees.
Boletinellus merulioides, commonly known as the ash-tree bolete, is a species of bolete fungus in the family Boletinellaceae. Described as new to science in 1832, it is found in Asia and eastern North America, where it grows on the ground near ash trees.
Calostoma cinnabarinum, commonly known as the stalked puffball-in-aspic,gelatinous stalked-puffball, or red slimy-stalked puffball, is a species of gasteroid fungus in the family Sclerodermataceae, and is the type species of the genus Calostoma. The fruit body has a distinctive color and overall appearance, featuring a layer of yellowish jelly surrounding a bright red, spherical head approximately 2 centimeters (0.8 in) in diameter atop a red or yellowish brown spongy stipe 1.5 to 4 cm tall. The innermost layer of the head is the gleba, containing clear or slightly yellowish elliptical spores, measuring 14–20 micrometers (μm) long by 6–9 μm across. The spore surface features a pattern of small pits, producing a net-like appearance. A widely distributed species, it grows naturally in eastern North America, Central America, northeastern South America, and East Asia. C. cinnabarinum grows on the ground in deciduous forests, where it forms mycorrhizal associations with oaks.
Sclerodermatineae is a suborder of the fungal order Boletales. Circumscribed in 2002 by mycologists Manfred Binder and Andreas Bresinsky, it contains nine genera and about 80 species. The suborder contains a diverse assemblage fruit body morphologies, including boletes, gasteroid forms, earthstars, and puffballs. Most species are ectomycorrhizal, although the ecological role of some species is not known with certainty. The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
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.
Aureoboletus betula is a species of mushroom producing fungus in the family Boletaceae. It is commonly known as the shaggy stalked bolete.
Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
Boletus nobilis, the noble bolete, is a species of edible basidiomycete mushroom of the genus Boletus found in eastern United States. Morphologically close to Boletus edulis, it is distinguished by an elongated stem, a beige skin and white pores, even when old.
