Summary:
Also listed in Jelly category. Guepiniopsis buccina produces small yellow to orange gelatinous cups with conspicuous longitudinal striations on exterior surface, and microscopically with septate cortical hairs with inflated cells, and absent clamp connections, growing usually on hardwood.

Microscopic:
spores (11)12-14.5(16) x 4-6 microns, cylindric to curved-cylindric, thin-walled with thin septa, tinted, apiculate, becoming 3-septate at maturity, germination by colorless, spherical to nearly spherical conidia or by germ tubes, probasidia 35-56 x 4.5-5.5 microns, cylindric-subclavate, with basal septa, becoming bifurcate; hymenium confined to inside of cup, consisting of basidia; internal hyphae "compactly arranged, thin-walled, roughened, septate, often with bulbous septa, clamp connections absent"; cortex and stem "covered by a palisade of thin- or thick-walled, septate hairs, individual cells typically inflated and hairs appearing catenate", "hairs thin-walled and smooth near hymenium, thick-walled and roughened on stipe and base of pileus", (McNabb), spore bearing surface is limited to inside of cup (Reid)

Notes:
It has been found in BC, WA, OR, ID, AB, ON, CA, CO, IA, MA, MI, MN, NC, NY, OH, SC, and VT, (Ginns), and Jamaica, Ecuador, Argentina, British Isles, Czechoslovakia, Eire, France, Germany, Italy, China, Japan, Australia, and New Zealand, (McNabb). It has been reported from Estonia, Poland, and Russia, (Reid). Lowy''s cited collections may be dubious because of the report of clamp connections.
