Summary:
Rimbachia neckerae is recognized by its small size, white pitcher-shaped or helmet-shaped to bell-shaped cap, a smooth to slightly wrinkled spore-bearing surface, fruiting on algal fluxes and amongst mosses on soil or old wood, and microscopically by the pip-shaped to broadly elliptic or almond-shaped spores.

Cap:
0.08-1.2cm across, urceolate (having the shape of a pitcher, with a large body and small mouth) to bell-shaped or conchate, thin, very delicate, translucent, margin incurved becoming uneven; white, (Redhead), 0.8-1.2cm across, urceolate, helmet-shaped to bell-shaped or conchate; white; smooth or minutely tomentulose, margin slightly fringed, incurved becoming even, (Watling)

Flesh:
thin; colorless (Watling)

Gills:
replaced by smooth surface that becomes wrinkled towards the center; white, (Redhead)

Stem:
eccentric rudimentary pseudostem, (Redhead), absent or replaced by eccentric rudimentary pseudostem (Watling)

Odor:
not recorded

Taste:
not recorded

Microscopic spores:
spores 8-10.5(12) x (4)5-6(7) microns, pip-shaped to broadly elliptic or almond-shaped, smooth, nonamyloid, thin-walled, with prominent apiculus; trama hyphae 5-11 microns wide, subparallel, only slightly interwoven, thin-walled, colorless, smooth, clamped, nonamyloid, the pellicular hyphae similar with the occasional end semi-erect and sometimes slightly clavate to capitate, (Redhead), pleurocystidia and cheilocystidia absent; clamp connections present, (Watling)

Spore deposit:
[presumably white or whitish, but not recorded]

Notes:
A collection was examined from BC (Redhead(7)), and it is also found (very rarely) in Europe.
