 Scientific Name: Hyphodontia lanata

Hyphodontia lanata Burds. & Nakasone, Mycologia 73: 461. 1981.

 Description: Basidiocarp effuse, adnate, loose-membranaceous or membranaceous when young, sub-ceraceous and somewhat brittle when old, 70-250 μm thick in section (aculei excluded). Hymenial surface Warm Buff or Light Buff, odontioid, cracked when old; margin paler, thinning, pruinose-arachnoid, filamentose, or floccose. Aculei separate, occasionally fused, 12-20 per mm, subulate, 30-100 (-200) × 15-80 (-150) μm. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, with rather loose texture when young, rather dense when old; hyphae richly ramified, somewhat interwoven, colorless or yellowish, distinct, 2.5-4 μm diam., with 0.3-0.9 μm thick walls. Hymenial layer with dense or rather compact texture; hyphae vertical, narrower and with thinner walls than those of subiculum. Hymenium and adjacent subhymenium IKI brownish, ± CB+. Aculei at first arising as yellowish sterile hyphal pegs, which then elongate and widen, eventually becoming covered by basidial elements from their bases towards their apices. Terminal hyphae of aculeal trama usually projecting and encrusted. Capitate cystidial elements few and encrusted in hymenium, numerous and smooth in subiculum, 13-24 × 6-8 μm, thin- or slightly thick-walled. Basidia utriform or subutriform, basally slightly thick-walled, often guttulate, 17-25 × 3.3-4.5 μm, 4-sterigmate. Basidiospores ellipsoid or narrowly ellipsoid, adaxially flattened, smooth, thin-walled, usually with several oil-drops, (5.3-) 5.5-6.2 (-6.5) × 2.9-3.4 μm, IKI-, CB-.

 Note: As Odontia vesiculosa G.H. Cunn. is a later homonym of O. vesiculosa Burt, Burd-sall and Nakasone (1981) named and redescribed the fungus as Hyphodontia lanata. After examining the holotypes of O. vesiculosa G.H. Cunn. And H. lanata, I can confirm their identity. Two paratypes of O. vesiculosa G.H. Cunn. were also studied: specimen PDD 18113 is H. lanata, while specimen PDD 18118 belongs to another species, having much wider basidiospores, each of them containing one large oil-drop. The consistency and texture of this species are very variable, depending on the specimen, and range from soft and loose-textured when young to subceraceous, somewhat brittle and dense-textured when old.
