what is the scientific name of Australia's most endangered marsupial and one of the world's most endangered mammals in which Gummivena is a fungal genus is found
Gummivena Gummivena is a fungal genus in the Mesophelliaceae family. The genus is monotypic, containing the single truffle-like species Gummivena potorooi, found in Western Australia. Described as new to science in 2002, "Gummivena" is intermediate in form between "Castoreum" and "Gummiglobus", and has a gleba with "veins" of gummy tissue and a three-layered peridium. The specific epithet "potorooi" refers the fact that the fungus is found only in the range of the rare and endangered species Gilbert's potoroo ("Potorous gilbertii").
Meridiolestida Meridiolestida is a clade of non-therian mammals from South America and Africa, and potentially also Australia. It is generally classified within Dryolestida, barring one study recovering them as the sister taxa to spalacotheriid symmetrodonts. However, more recent studies have stuck to the dryolestoid interpretation. They differ from northern dryolestoids in the absence of a parastylar hook on the molariform teeth and the lack of a Meckelian groove.
