Species Information
Summary:
Bisporella sulfurina is a minute, yellow, shallow cup with almost no stem, that grows on hardwood logs in association with pyrenomycetes which are often small, round, crust-like, and black. It can be minutely downy on the exterior but is otherwise bald. It tends to be tightly clustered, unlike Bisporella citrina which is not particularly associated with pyrenomycetes. But some authors regard the two species as synonyms. Bisporella sulfurina (Quel.) S.E. Carp. was synonymized with Calycina citrina (Hedw.) Gray by Baral(2) in 2013 who synonymized Bisporella citrina (Batsch: Fr.) Korf and S.E. Carp with Calycina citrina as well. |The original basionym was spelled ''sulphurina''.
Odor:

Microscopic:
spores 8-11 x 2-2.5 microns, narrowly elliptic to fusoid, "sometimes curved, smooth, 1-septate"; asci "inoperculate, tips inamyloid"; paraphyses filiform, with yellow granules, (Desjardin), spores 8-11 x 1.5-2.5 microns, cylindric, "smooth, often with oil droplets", (Siegel), spores 8-10(12) x 2 microns, elliptic-fusiform, "sometimes rather curved", smooth, colorless, "with 1 septum", usually with 4 droplets; asci 8-spored, 60-90 x 4-4.5 microns, iodine negative; paraphyses "filiform, filled with many yellow droplets", (Breitenbach)
Notes:
There are collections from BC at the University of British Columbia, identified by O. Ceska. It is included for CA by Desjardin(6) and Siegel(2).

Habitat and Range
SIMILAR SPECIES
Bisporella citrina "has larger fruiting bodies not growing in clusters and does not occur on Sphaeriales" (Breitenbach(1)). B. citrina forms slightly larger fruitbodies (0.1-0.3cm) "that grow gregarious but not clustered, is not associated with pyrenomycete crusts, and has slightly broader spores" 3-3.5 microns wide, (Desjardin(6)). Yellow species of Hymenoscyphus are distinctly stalked (Breitenbach(1)). There are many other yellow disc fungi that are difficult to identify.Habitat
gregarious or in small clusters "on hardwood logs, usually associated with old, black, crustose fruitbodies of a pyrenomycete", fall through early spring, (Desjardin), often "in small masses of many fruitbodies or in scattered troops on decaying logs, branches or woody debris, almost always with small, round, black fruitbodies of a Pyrenomycete present", generally "found on oak and Tanoak, but will occur on many different hardwoods", (Siegel), occasionally single, "but usually compactly clustered and fused at the base", growing on dead branches of hardwood trees, "usually on old fruiting bodies of Sphaeriales", fall-spring, (Breitenbach)
