Pleuro- and caulocystidia none. Cuticle a cutis of repent cylindrical, pigmentless hyphae (6-12 µm diam.), membrane thill-walled, and not gelatinized. Clamp-connections present.

Notes

According to the descriptions E. peralbidum is related to E. albidum Murrill and E. murrillii Hesler, both native in North America. The species from New Zealand, however, is distinguished by its more robust habit, conspicuous cheilocystidia and presence of clamp connections.
