Summary:
Also listed in Crusts category. Features include 1) flat growth on wood with pores facing outward, 2) a thin, soft fruitbody when fresh, the whitish then ochraceous surface with rounded pores or especially on vertical substrates lacerate or labyrinthine pores, 3) an indistinct, pruinose margin, and 4) microscopic characters including cylindric cystidia and relatively small allantoid spores. The description is derived from Eriksson(4) except where noted.
In the Pacific Northwest, Hyphodontia latitans is known from one collection in BC, (Ginns(28)). It has been found in AR, AZ, FL, GA, IA, IL, IN, MD, MI, MS, NC, NM, SC, TN, and VA, (Ginns(5)). It also occurs in central Europe and Siberia in Russia, (Eriksson).
Cap:
growing flat on wood, adnate [firmly attached], about 0.1-0.2cm thick, "at first whitish then ochraceous, when alive soft, when dried firm and friable"; margin indistinct, pruinose; subiculum very thin, (Eriksson), growing flat on wood, "usually fertile to the margin", (Gilbertson)
Flesh:
context less than 0.1cm thick, tan to pale buff, trama continuous with tube layer, (Gilbertson)
Pores:
spore-bearing surface "poroid with rounded pores" or, especially on vertical substrates, "with irregularly lacerate or labyrinthine pores", (Eriksson), spore-bearing surface tan, the pores 1-3 per mm, angular, "with thin, entire dissepiments that split deeply and become lacerate". tube layer up to 0.2cm thick, "tubes cream buff within", (Gilbertson)
Microscopic:
spores 3-4 x 0.8 microns, narrowly allantoid, more or less curved, smooth, thin-walled, inamyloid; basidia 4-spored, 8-10 x 3-3.5 microns, short-cylindric, more or less constricted, with basal clamp connection; cystidia numerous in the hymenium, 30-35 x 4-5 microns, slightly projecting, cylindric or slightly fusiform, "somewhat sinuous and constricted", thin-walled, "obtuse, without incrustation"; hyphal system monomitic, hyphae about 3 microns wide, with clamp connections, "with somewhat thickened walls, frequently branching from clamp-cells or opposite clamp", hyphae of dissepiments arranged in parallel fashion, "those of the subiculum irregularly intertwined", "hyphae of the thickening subhymenium densely united", narrower and more thin-walled, (Eriksson), spores 3.5-5 x 0.5-0.8 microns, narrowly allantoid, smooth, inamyloid, colorless; basidia 4-spored, 10-12 x 3-3.5 microns, clavate, with basal clamp connection; cystidia "cylindric, with refractive contents, thin-walled, smooth, mostly imbedded", projecting to 10 microns, 25-35 x 3-4.5 microns, with a basal clamp connection "or branching directly from a generative hypha"; hyphal system monomitic, generative hyphae in context 2-4 microns wide, thin-walled, with clamp connections, "with occasional branching", hyphae in trama similar
