Summary:
Features include 1) resupinate growth on conifer wood, 2) a whitish to grayish white fruitbody, very thin, porulose and discontinuous, thickening somewhat when old, slightly bristly from projecting cystidia, the margin thinning out and indistinct, 3) spores that are round, smooth, and inamyloid, 4) basidia that are clavate and inamyloid, with basal wall thickening, 5) cystidia that are subcylindric, strongly amyloid, bi-rooted, blunt, thick-walled in the lower part, the walls gradually thinning out toward the apex, and 6) a monomitic hyphal system, the hyphae with clamp connections.
Tubulicrinis globisporus has been found in BC (Ginns). It has also been found in Sweden and reported from France, Germany, and Italy, (Hjortstam(4)), as well as Norway and Sweden, (Hjortstam(6)).
Fruiting body:
resupinate, effused [spread out], "when young very thin and somewhat inconspicuous, with age thickening, whitish to greyish white, under a lens slightly pilose due to the projecting cystidia"; margin indistinct, (Hjortstam(4)), resupinate, as a rule very thin, porulose and discontinuous; whitish or in the herbarium sometimes pale ochraceous; pilose from projecting cystidia; margin thinning out, not determinable, (Hjortstam(6))
Microscopic:
SPORES about 4 microns across, nearly round, inamyloid; BASIDIA 4-spored, 13-15 x 5-7 microns, clavate, inamyloid, basal wall thickening; CYSTIDIA frequent, 90-120 x 5-7 microns, subcylindric, strongly amyloid, bi-rooted, "thick-walled in lower part, the walls gradually thinning out towards the apex, upper part not expanded"; HYPHAE monomitic, 2.5-4 microns wide, thin-walled to slightly thick-walled, inamyloid, with clamp connections, (Hjortstam(4)), SPORES 4.5-5(5.5) microns in diameter, obliquely round [also referred to as "subglobose", illustrated with definite apiculus], smooth, thin-walled; BASIDIA 4-spored, 10-15(18) x 5-7 microns, subclavate, "basally with slight wall thickening, forming rather loose clusters, inamyloid", with basal clamp connection; CYSTIDIA 70-120 x 5-7 microns, cylindric, "not or only slightly widened toward the obtuse apex, capillary lumen expanded gradually with the upper, thin-walled part more than 10 microns long", the cystidia usually very strongly amyloid; HYPHAE monomitic, 3-3.5 microns wide, with clamp connections, "thin-walled or with slight wall thickening", "arranged in a very thin and inamyloid tissue", (Hjortstam(6))
