  In Australia, reported from a single collection from Thursday Is., Qld. However the specimen in US is a mixed collection comprising mainly R. samoensis, with only fragments of a second species, possibly R. relicinula. Because of the quality of this specimen, the above description is from Malaysian collections. A widespread species in the Philippines, West Malaysia and Indonesia (Java). Grows on bark.
