Perenniporia stipitata is a species of poroid fungus in the family Polyporaceae. Found in Brazil, it was described as a new species in 1987 by Norwegian mycologist Leif Ryvarden.

Taxonomy

The holotype of P. stipitata was collected in Caracaraí, a municipality in the state of Roraima.[2] According to Cony Decock and Ryvarden, the fungus Microporellus subincarnatus, described by E. J. H. Corner from Brazilian collections in 1987,[3] is the same species as P. stipitata.[1]

Description

The fungus features a stipe (up to 15 mm (0.6 in) long) that is laterally attached to its semicircular or fan-shaped cap. The presence of a stipe is unique in the genus Perenniporia. The cap surface is smooth, and ochre to pale brown in colour. The pores on the cap underside are tiny, measuring 8 to 10 per millimetre. It has a dimitic hyphal system with clamps in the generative hyphae; the skeletal hyphae are thick-walled and have a strong dextrinoid reaction with Melzer's reagent. Spores are more or less spherical to truncate, thick-walled, and measure 5–6 by 3–4 μm.[2]
