Used references: Arora, Mushrooms Demystified. I believe these are older specimens. The 2nd photo appears to show the dark charcoal weathered tufted hairs of Cyathus h. The interior cup is rather light for this species, but may have been caused by heavy rainfall.

most people haven’t. Jason. I’m developing a sense that C. helenae is often charcoal-gray or charcoal-purple in color; with thick-walled nests and tufted hairs on the exterior, which can become waterlogged and clumped together in age and very wet weather. Some specimens have a white or at least a lighter edged rim to the nest as well.

Neat, thanks!

C. helenae, and I mighty be wrong, Jason. According to Arora, helenae is found on arid or alpine habitats, has a thicker-walled nest with tufted hairs on the exterior (see other obs. on MO). Tufted hairs are more obvious on younger material as are the thicker walls. Not all obs. on MO include the exterior bases of the “nest” and can therefore be identified. There is often a whitish-cup rim on some specimens which is not noted in the description. Perhaps a remnant of the egg stage?
