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").
