Taxonomy
editThe genus was circumscribed by the Finnish mycologist Tuomo Niemelä in 2005 to contain the species Rhodonia placenta.[2]
Species
editThe following species are recognised in the genus Rhodonia:[3]
- Rhodonia obliqua (Y.L.Wei & W.M.Qin) B.K.Cui, L.L.Shen & Y.C.Dai (2018)
- Rhodonia placenta (Fr.) Niemelä, K.H. Larss. & Schigel (2005)
- Rhodonia rancida (Bres.) B.K.Cui, L.L.Shen & Y.C.Dai (2018)
- Rhodonia subplacenta (B.K.Cui) B.K.Cui, L.L.Shen & Y.C.Dai (2018)

Description
editThe fruiting bodies of species of the genus Rhodonia are spread out (effused) on its substrate, poroid, fairly thick, juicy and soft, with a pale rose or white colouring. It has a monomitic hyphal system (containing only generative hyphae), and the hyphae have clamp connections. These hyphae are initially thin-walled but become thick-walled in mature fruit bodies. The spores are cylindric.[2]
