Observation 98621: Calicium
When: 2012-06-27
(47.4288° 117.5936° 701m)
Herbarium specimen reported

Notes: Substrate: underside of Ponderosa pine branch (~8cm diameter) leaning up against 50+year old Ponderosa pine.

Habitat: Ponderosa pine grove on edge of wetland. (southwestern edge of Upper Turnbull Slough). Nearby plants include shrubby Salix sp, sedges/rushes.

Description: primary thallus bright green. Stalk- about 1mm tall, uniform in thickness, black. Capitulum- black. Basal crust- bright green and yellow. Spores- greenish-black under LM, appear to be two-celled, each cell quite spherical some spores look single celled and spherical however this is probably due to orientation of spores (9-)10-11(-12) x 5-6 (n=6). Asci are unclear, cannot be seen, assuming this means the mazaedium is “true”. (LM photos to post later)

Heh, and it may be totally unrelated, too…

like black cherries, yum! Those are up next — thanks for the hint that they’re related to Basidia, hopefully the Basidia here are easier than over over in Europe, i.e. discussion thread on observation 92893.

Nice little nook!

Look at those juicy Bacidia-like crusts as well! Mouth-watering.
