Question: What fungus, which is widely distributed across the Northern Hemisphere is related to the fungus Bloetus austroedulis?
Context: Guepinia is a genus of fungus in the Auriculariales order.  It is a monotypic genus, containing the single species Guepinia helvelloides, commonly known as the apricot jelly.  The fungus produces salmon-pink, ear-shaped, gelatinous fruit bodies that grow solitarily or in small tufted groups on soil, usually associated with buried rotting wood.  The fruit bodies are 4 – tall and up to 17 cm wide; the stalks are not well-differentiated from the cap.  The fungus, although rubbery, is edible, and may be eaten raw with salads, pickled, or candied.  It has a white spore deposit, and the oblong to ellipsoid spores measure 9–11 by 5–6 micrometers.  The fungus is widely distributed in the Northern Hemisphere, and has also been collected from South America. Boletus edulis (English: penny bun, cep, porcino or porcini) 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, and New Zealand.  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 ("Boletus edulis" var.  "grandedulis") is a large, darker-coloured variant first formally identified in 2007. Lactifluus volemus, formerly known as Lactarius volemus, is a species of fungus in the family Russulaceae.  It is widely distributed in the northern hemisphere, in temperate regions of Europe, North America and Asia as well as some subtropical and tropical regions of Central America and Asia.  A mycorrhizal fungus, its fruit bodies grow on the ground at the base of various species of trees from summer to autumn, either individually or in groups.  It is valued as an edible mushroom, and is sold in markets in Asia.  Several other "Lactifluus" mushrooms resemble "L. volemus", such as the closely related edible species "L. corrugis", but these can be distinguished by differences in distribution, visible morphology, and microscopic characteristics.  "L. volemus" produces a white spore print and has roughly spherical spores about 7–8 micrometres in diameter. Glutinoglossum glutinosum, commonly known as the viscid black earth tongue or the glutinous earthtongue, is a species of fungus in the family Geoglossaceae (the earth tongues).  Widely distributed in the Northern Hemisphere, it has been found in northern Africa, Asia, Europe, and North America.  Although previously thought to exist in Australasia, collections made from these locations have since been referred to new species.  "G. glutinosum" is a saprophytic species that grows on soil in moss or in grassy areas.  The smooth, nearly black, club-shaped fruitbodies grow to heights ranging from 1.5 to .  The head is up to 0.7 cm long, and the stipes are sticky.  Several other black earth tongue species are quite similar in external appearance, and many can be reliably distinguished only by examining differences in microscopic characteristics, such as spores, asci, and paraphyses.  First described in 1796 as a species of "Geoglossum", the fungus has gone through several changes of genera in its taxonomic history.  It was placed in its current genus, "Glutinoglossum", in 2013. Auriscalpium is a genus of mushrooms typifying the family Auriscalpiaceae and characterized by in part by rough-walled, amyloid spores that are produced on pendant spines, hence it is considered to be a tooth fungus.  The type species, "A. vulgare", is a common, easily identified fungus in the Northern Hemisphere found fruiting exclusively on mature, fallen, often buried conifer cones. Its wiry, long hairy stipe is topped by an eccentrically placed, shaggy pileus bearing the pendant, flexible, spore-bearing spines.  The entire fructification resembles and perhaps could be used as an ear pick (see etymology below).  Other species in the genus do not occur on cones or lack the eccentric pileus on a long stalk.  According to the "Dictionary of the Fungi" (10th edition, 2008), the genus contains eight widely distributed species. Tremella mesenterica (common names include yellow brain, golden jelly fungus, yellow trembler, and witches' butter) is a common jelly fungus in the Tremellaceae family of the Agaricomycotina.  It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus "Peniophora".  The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm diameter, has a convoluted or lobed surface that is greasy or slimy when damp.  It grows in crevices in bark, appearing during rainy weather.  Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain.  This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America.  Although considered bland and flavorless, the fungus is edible.  "Tremella mesenterica" produces carbohydrates that are attracting research interest because of their various biological activities. Paxillus involutus, commonly known as the brown roll-rim, common roll-rim, or poison pax, is a basidiomycete fungus widely distributed across the Northern Hemisphere.  It has been unintentionally introduced to Australia, New Zealand, and South America, where it has likely been transported in soil with European trees.  Various shades of brown in colour, the fruit body grows up to 6 cm (2.4 in) high and has a funnel-shaped cap up to 12 cm (5 in) 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. Boletus austroedulis is a species of bolete fungus in the family Boletaceae.  Described as new to science in 2014, it is found in Australia, where it grows in groups on the ground under pink bloodwood ("Corymbia intermedia") and rose she-oak ("Allocasuarina torulosa").  It is thought to be the first member of "Boletus" section "Boletus" (commonly known as the porcini) that is endemic to Australia.  Although "Boletus edulis" has previously been reported from the continent, it is always in association with introduced trees, suggesting that itself is also introduced.  The type collection was made in Davies Creek National Park in Queensland. Sarcoscypha coccinea, commonly known as the scarlet elf cup, scarlet elf cap, or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales.  The fungus, widely distributed in the Northern Hemisphere, has been found in Africa, Asia, Europe, North and South America, and Australia.  The type species of the genus "Sarcoscypha", "S. coccinea" has been known by many names since its first appearance in the scientific literature in 1772.  Phylogenetic analysis shows the species to be most closely related to other "Sarcoscypha" species that contain numerous small oil droplets in their spores, such as the North Atlantic island species "S. macaronesica".  Due to similar physical appearances and sometimes overlapping distributions, "S. coccinea" has often been confused with "S. occidentalis", "S. austriaca", and "S. dudleyi". Armillaria luteobubalina, commonly known as the Australian honey fungus, is a species of mushroom in the family Physalacriaceae.  Widely distributed in southern Australia, the fungus is responsible for a disease known as "Armillaria" root rot, a primary cause of "Eucalyptus" tree death and forest dieback.  It is the most pathogenic and widespread of the six "Armillaria" species found in Australia.  The fungus has also been collected in Argentina and Chile.  Fruit bodies have cream- to tan-coloured caps that grow up to 10 cm in diameter and stems that measure up to 20 cm long by 1.5 cm thick.  The fruit bodies, which appear at the base of infected trees and other woody plants in autumn (March–April), are edible, but require cooking to remove the bitter taste.  The fungus is dispersed through spores produced on gills on the underside of the caps, and also by growing vegetatively through the root systems of host trees.  The ability of the fungus to spread vegetatively is facilitated by an aerating system that allows it to efficiently diffuse oxygen through rhizomorphs—rootlike structures made of dense masses of hyphae.
