Nidula niveotomentosa

Nidula niveotomentosa

Nidula niveotomentosa is a fungi in the family Agaricaceae, and is a bird's nest fungi. Nidula niveotomentosa is easily recognized when young by its pubescent, white, cylindrical fruiting bodies and small brown peridioles embedded in mucilaginous gel. Older specimens may be matted, pale-grey to brown, leading to confusion with Nidula candida. The latter, despite the species name which means "white," is actually greyish to brown, and shaggy to finely squamulose when young. Nidula candida is also larger, up to 15 mm tall, 8 mm broad, and has a fruiting body that flares broadly at the mouth. Both species are common, but Nidula candida is more northern in distribution. Species of Cyathus and Crucibulum also bear a resemblance to Nidula tomentosa but can be distinguished by peridioles that are attached to the cup wall by a thin cord (use hand lens) rather than embedded in a mucilaginous gel.
