Question: What fungus, which is widely distributed across the Northern Hemisphere is related to the fungus Bloetus austroedulis?

<P0-S0> Armillaria luteobubalina, commonly known as the Australian honey fungus, is a species of mushroom in the family Physalacriaceae. <P0-S1>  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. <P0-S2>  It is the most pathogenic and widespread of the six "Armillaria" species found in Australia. <P0-S3>  The fungus has also been collected in Argentina and Chile. <P0-S4>  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. <P0-S5>  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. <P0-S6>  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. <P0-S7>  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. <SEP> <P1-S0> Boletus edulis (English: penny bun, cep, porcino or porcini) is a basidiomycete fungus, and the type species of the genus "Boletus". <P1-S1>  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. <P1-S2>  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. <P1-S3>  The western North American species commonly known as the California king bolete ("Boletus edulis" var. <P1-S4>  "grandedulis") is a large, darker-coloured variant first formally identified in 2007. <SEP> <P2-S0> 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. <P2-S1>  It has been unintentionally introduced to Australia, New Zealand, and South America, where it has likely been transported in soil with European trees. <P2-S2>  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. <P2-S3>  Although it has gills, it is more closely related to the pored boletes than to typical gilled mushrooms. <P2-S4>  It was first described by Pierre Bulliard in 1785, and was given its current binomial name by Elias Magnus Fries in 1838. <P2-S5>  Genetic testing suggests that "Paxillus involutus" may be a species complex rather than a single species. <SEP> <P3-S0>  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"). <P3-S1>  It is thought to be the first member of "Boletus" section "Boletus" (commonly known as the porcini) that is endemic to Australia. <P3-S2>  Although "Boletus edulis" has previously been reported from the continent, it is always in association with introduced trees, suggesting that itself is also introduced. <P3-S3>  The type collection was made in Davies Creek National Park in Queensland. <P3-S4> Boletus austroedulis is a species of bolete fungus in the family Boletaceae.
