psidium
on dead stumps, trunks, fallen branches, etc. It is apparently frequent on Calamus sp. in the East, but has also been reported on Alpinia aromatica (Berkeley 1856); Erythrina crista-galli (Spegazzini 1899); Ficus, Hevea brasiliensis, Plectocomia elongata, and Psidium guajava (Theodoro 1937). There is, however, one very interesting collection in the Kew Herbarium from Venezuela (Dennis 1335) with the following information "on flat stony soil, full of fragments of mica schist much permeated by the mycelium. Marked rhizomorphs present but no rotten wood or roots found beneath on digging." This is a most atypical habitat and despite the fact that no buried wood was found in the immediate vicinity it is almost certain that the fungus was connected with such a substrate, as the presence of rhizomorphs suggests.
