Paralpova Cabero & P. Alvarado, in Alvarado, Cabero, Moreno-Mateos, Vizzini, Alonso, Lebeuf, Siquier & Vidal, Mycologia 113(4): 835 (2020)
Index Fungorum number: IF833076; Facesoffungi number: FoF12590
Diagnosis: Sequestrate hypogeous fungi with a remark- able odor, gleba with gel-filled chambers when mature, bilayered peridium (prosenchymatic peridiopellis and pseudoparenchymatic subpellis), monosporic (rarely bis- poric) basidia, ellipsoid or fusiform spores >15 µm. Associated with Fagus sylvatica.
Etymology: Paralpova, the prefix para– (Greek) mean- ing “beside” in reference to the phylogenetic placement of this genus as sister to Alpova.
Type species: Paralpova artikutzensis, sp. nov.
Notes: – Paralpova is phylogenetically distinct from Neoalpova and the core clade of Alnus-associated species of Alpova. Paralpova and Neoalpova might be inter- preted as sections of Alpova because of the pseudopar- enchymatic structure of their subpellis that is absent in Melanogaster (which has a single-layered prosenchy- matic peridium). However, Paralpova has not been reported from Alnus roots by now, has monosporic or bisporic basidia, spores >15 µm long with Qm < 2.0, and lacks clamp connections, important features different from Alpova. Therefore, a new genus is here proposed to represent these differences.
