Summary:
Features include 1) an amber to dark red-brown, firm-gelatinous, obconic to more irregular fruitbody with a central attachment, 2) growth on hardwood in loose clusters without much anastomosis, and 3) microscopic characters.

Microscopic:
spores 9-14 x 3.5-4(5) microns, cylindric with broadly rounded ends in face view, in side view somewhat curved, smooth, inamyloid, colorless, thin-walled; basidia 4-spored, (14)17-19 x 8-9 microns, narrowly clavate when mature, broadly ovoid, ellipsoid, or narrowly clavate when younger, sessile, with a basal clamp connection, longitudinally and cruciately septate, with 4 elongated epibasidia; spore-bearing surface about 30 microns thick of immature and mature basidia, and colorless dendrohyphidia; on non-spore-bearing surface there is in vertical sections from dried specimens "an external layer 15-30 microns thick, impregnated with a yellow-brown, resin-like substance, and comprised of rather closely arranged dendrohyphidia (similar to those in the hymenium)"; context of colorless thin-walled hyphae 1.5-3.5 microns wide, with clamp connections, and having some segments with a roughened surface due to minute amorphous deposits, these hyphae being loosely woven and embedded in a gelatinous matrix, (Ginns(9)), spores 14-15 x 3-3.5 microns, cylindric, allantoid (curved), smooth, inamyloid, colorless, often with several drops, also conidia 5-6 x 1.5-2 microns; hypobasidia 8-15 x 6-10 microns, nearly spherical to pyriform [pear-shaped], longitudinally septate, usually with 4 finger-like basidia; hyphae 1-3 microns wide, gelatinized, septa with clamp connections, (Breitenbach), spores 10.5-14 x 3-5 microns, allantoid, colorless, white in mass; probasidia 10-16 x 4-11 microns, elongate, becoming cruciate-septate; hymenium unilateral, mostly confined to inferior parts, smooth, the sterile upper parts covered with minute scale-like patches, (Martin)

Notes:
Klett(2) designates Bandoni 945 and 2743 from BC (the latter deposited at University of British Columbia as E. recisa), as well as six of his own collections from WA as Exidia crenata (Schw.) Fr., but says that he cannot say whether the latter species is the same as E. recisa of Europe. E. recisa has been reported from OR (Zeller). There are collections from BC at the University of British Columbia by R. Bandoni and others. The distribution of E. recisa includes ID, AB, NS, ON, PQ, YT, CA, GA, LA, MD, MN, NC, and OH, (Ginns), North America, Europe including Switzerland, and Asia (Breitenbach), Mexico and Germany, (Lowy), and the Philippines (Raitviir).
