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). References
