Rossbeevera is a genus of sequestrate (truffle-like) fungi in the family Boletaceae.

[2] The genus was created to contain species formerly placed in Chamonixia, but characterized by having ellipsoid to spindle-shaped spores with 3–5 longitudinal ridges, bluish-green to deep blue fruit body staining reaction, and a thin whitish peridium.

The Chinese species R. yunnanensis is the earliest diverging lineage within the genus, and has a close phylogenetic relationship with the bolete genera Turmalinea and Leccinellum.

[3] [4] The genus name Rossbeevera honours Ross Beever (1946–2010), a New Zealand botanist and mycologist.
