Description
The 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]
