Examination of the type material (together with additional collection made in New
Zealand) justify this proposed combination. Spores oval to subcylindrical, neither
amyloid nor dextrinoid, hyaline, smooth, 7-8.5 X 4-4.5 µ. Cheilocystidia
conspicuous, thin-walled, with yellow plasmatic pigment in KOH, clamp
connections present. Pleurocystidia none.
