Used references: Arora, Mushrooms Demystified. Key aspects are nest without a lid, spores embedded in red muscilage (5 of 6 present). Nidula has a lid on the nest, Nidularia has a fibrous top which tears irregularly to expose the nest, and is soon degraded.

Yes, but…

in Arora’s key to the Nidulariales, p. 779, Mushrooms Demystified, couplets 2a and 3a are:

“2a: Fruiting body lacking a “lid” when young, at first round to cushion-shaped and more or less covered with a felty or powdery material that ruptures irregularly; nest soon disintegrating; eggs embedded in a sticky mucilage which eventually dries out.

“3a: Eggs brown to reddish, round and flattened (lens-shaped); not common…”

Interior of most opened “nests” in this obs. show visible red mucilage. Only one species in Arora’s key has red mucilage. Since all nests that are opened show spores, I don’t think the distinction between cups and balls or sacs is appropriate.

You state “Both Nidula and Nidularia have small brown peridioles embedded in gel.” True. But only Nidularia farcta has red peridioles in red mucilage. In Arora’s key there are no Nidula that have red mucilage nor red peridioles.

There is a single sporocarp which has gray peridioles present. But the majority of sporocarps have red spores and/or red mucilage within them.

Nidula vs Nidularia

Nidularia does NOT form cups. They do not make persistent tubes. Nidularia forms sacs in the shape of a ball and the sac disintegrates after splitting open. They’re not splash cups. Nidula forms a cup that remains at maturity, like Cyathus and Crucibulum. Both Nidula and Nidularia have small brown peridioles embedded in gel.

Do you know something not mentioned in Arora, Darv?

In Mushrooms Demystified, the ONLY bird’s nest fungus with spores embedded in red muscilage is Nidularia farcta. In this photo, 5 of 6 sporocarps have red muscilage, making Nidula candida impossible.
