Dingleya Trappe 1979

Description

Ascocarps hypogeous, with a brown, verrucose peridium. Gleba white with rounded to narrow, labyrinthine chambers lined with a hymemal palisade and filled with asci, paraphyses and spores. Asci cylindric, mostly 8-spored. Spores globose to ellipsoid, hyaline to brown, ornamented with cyanophilic, rounded to irregular warts or ridges. Type species: Dingleya verrucosa Trappe.

Etymology: In honour of New Zealand mycologist, Miss Joan M. Dingley.

Notes

The type species, D. verrucosa, has ellipsoid spores in contrast to the other species, which have globose spores. In most other ways, however, D. verrucosa shows close affinity with the other species. Spore shape frequently is not a critical generic character in the Pezizales: other characters of ascocarps, especially ectal excipular (peridial) anatomy, often seems to more closely define affinities or differences between taxa.
