E-Flora BC: Electronic Atlas of the Flora of British Columbia

Summary:
Also listed in Polypores category. Features include 1) effused growth on wood, bark, leaves, moss, old hyphae, bone, or gravel, 2) a thin, buff to pale yellow or ocher, loosely attached, membranous crust with a meruloid to poroid surface, the margin floccose to fibrillose and the same color or slightly paler, 3) spores that are (mostly) oval, inamyloid, colorless to slightly yellowish, presumably cyanophilic, with spines 0.5-1.0 microns long and small crests, 4) basidia that are 4-spored, with variable numbers of large globules, presumably with cyanophilic content, and 5) a monomitic hyphal system, the hyphae with ampulliform swellings at the clamp connections. The online Species Fungorum, accessed September 7, 2005 and September 8, 2012, gave the current name as Mycolindtneria leucobryophila (Henn.) Rauschert. The 10th Edition of Dictionary of the Fungi synonymizes Mycolindtneria with Lindtneria.

Collections were examined from BC, OR, ON, IA, Denmark, France, Germany, Italy, and the United Kingdom, (Liberta). It is known in Europe from Denmark, Germany, Spain, and Yugoslavia (Ryvarden).

Fruiting body:
"effused, adnate, appearing membranous, subpelliculose, to occasionally floccose under a lens", ''pale luteous'', ''buff'', or ''ochreous''; margin "floccose or fibrillose to occasionally rhizomorphic", the same color as the spore-bearing surface or slightly paler, (Liberta), resupinate, soft and membranaceous when fresh, brittle, loosely attached, hymenium meruloid (at first) to poroid (when more mature), pores 1-3 per mm, surface cream to pale straw or ochraceous; subiculum thin and white, (Ryvarden), resupinate, irregular, patchy, loosely attached to substrate; bruising rich yellow; smooth or poroid, context cottony, soft, pale yellowish; margin "variable, distinct to fibrous"; spore deposit "yellowish to white", (Buczacki)

Microscopic:
SPORES 5.5-11.5 x 4-7(7.5) microns, mostly oval, occasionally oval-elliptic, rarely broadly fusiform-elliptic, asperulate to spinulose, the spines 0.5-1.0 microns long, inamyloid, colorless to slightly yellowish, wall thin to slightly thickened (0.5 microns); BASIDIA 4-spored, 20-32(57) x 7-11 microns, "flexuous, subclavate to clavate", "containing variously sized oily droplets", sterigmata 5-6 microns long; in section up to 400 microns; HYPHAE "monomitic, crystalline material scattered among the hyphae", hyphae 3-5.5 microns wide (with ampulliform swellings at the clamp connections up to 13 microns wide), colorless to slightly yellowish brown, thin-walled to slightly thick-walled (0.5 microns), (Liberta), SPORES 8-10 x 6-7 µm (including ornamentation), elliptic, strongly ornamented with spines and small crests, yellowish to pale brownish, inamyloid, slightly thick-walled; BASIDIA 4-spored, 35-55 x 7-10 microns, clavate to sinuous and slender, with basal clamp connections, varying numbers of large globules; CYSTIDIA and other sterile elements absent from hymenium; HYPHAE monomitic: generative hyphae with clamp connections at all septa, in the trama usually 3-6 microns wide, in the subiculum much wider and up to 12 microns wide, (Ryvarden), SPORES 8-10 x 5.5-6.5 microns excluding ornamentation, markedly spiny with spines 1.5-2.5 microns long; BASIDIA 4-spored, 35-55 microns long, clavate; CYSTIDIA absent; HYPHAE monomitic, (Buczacki)
