Species Information
Summary:
{See also Common Bird''s Nests Table.} Features include 1) an inverted cone-shaped, shaggy brown cup with setae on the edge, 2) strongly radially striate, brownish gray interior covered at first by a whitish membrane, and 3) slightly triangular dark eggs attached by a cord. The sides of the cup are angled so that raindrops falling into the mushrooms dislodge the spore sacs (eggs), (Lincoff(2)). In the air the cord attached to the egg acts like a whip, enabling the egg to become attached to blades of grass, (Lincoff(1)).
Microscopic:
spores 18-20 x 8-10 microns, elliptic, slightly narrower at one end, thick-walled, with a notch or apiculus at one end, (Brodie(1)), 18-22 x 8-12 microns, elliptic, white, (Lincoff(1)), spores 15-22 x 8-12 microns, elliptic, notched at one end, smooth, (Phillips)
Notes:
Cyathus striatus is found in WA, AL, CO, CT, GA, IA, IN, MT, NY, OH, PA, WI, Puerto Rico, and Mexico, (White). It is very widespread in the temperate world, Canada including BC and AB, United States, Mexico, India, China, Japan, (Brodie(1)). It also occurs in Europe (Courtecuisse). The University of British Columbia has collections from BC and Thailand, the University of Washington has collections from WA, IA, and VA, and Oregon State University has collections from OR, OH, and PA.

Habitat and Range
SIMILAR SPECIES
Cyathus helenae has tufted tomentum, has faint pleating, lacks setae, and has different habitat, as well as biochemical differences, (Brodie(1)). Spores of C. helenae are similar in size but mostly oval instead of elongate as in C. striatus, (Brodie(2)). Other Cyathus species in the Pacific Northwest are not pleated. See also SIMILAR section of Cyathus olla and Cyathus stercoreus.Habitat
in open woodland on small twigs and woody leaf mould, occasionally in gardens, (Brodie(1)), can grow in manure, but more common on sticks and other vegetable matter, (Arora), scattered or in groups on dead wood or vegetable debris in open woods, July to October, (Phillips), on dead wood, bark, twigs, and wood chips, in open woods, (Lincoff(2)), "on decaying plant materials such as wood chips, small branches, and needles", (Trudell)
