Public Note:
[GC] Pilei annual, scattered, waxy, fragile, 0.2-0.5 mm. diameter, attached by a narrow base, cupulate or as often pendent; exterior white, drying cream, tomentum of long, unbranched aseptate hyphae, tortuous, 3 µ diameter, finely crystal coated, tapering gradually to long-acuminate apices; margin inturned, lacerate when old; hymenial surface concave, even, pallid buff or cream. Context white, to 40 µ thick, base to 250 µ, of parallel hyphae radiately arranged; generative hyphae to 2.5 µ diameter, wall 0.25 µ thick, sparsely branched, septate. Hymenial layer to 35 µ deep, paraphyses subclavate. Basidia subclavate, 12-16 x 7-8 µ, 4-spored. Spores broadly fusiform or lemon-shaped, apiculate, 6-9 x 4.5-5.5 µ, smooth, hyaline. Notes: Tomentum hairs are long, unbranched, thin-walled and taper gradually to acuminate finely crystal-coated apices, the main stem being covered with coarse crystals. Abhymenial hairs and spores are the main features by which the species is separated from L. villosa, which it resembles in many macrofeatures. Hairs are filiform, unbranched, thin-walled, and taper gradually to long-acumiijate apices. Walls are crystal encrusted, crystals becoming smaller and more closely arranged towards the apices. Spores are broadly fusiform or limoniform with acuminate apices. [JAC] Frbs white, unlike coprosmae. A typical Flagelloscypha. No dextrinoid reaction. Basal hyphae yellowish brown. Hair encrustation granular, thinning to absent on tapered ends, thick walled. Spores (including apiculus) length=7.2–8.6µm (µ=7.9, σ=0.41), width=3.9–5.4µm (µ=4.6, σ=0.45), Q=1.4–2.1µm (µ=1.73, σ=0.19), n=20. Note that Incrustocalyptella p does not have whip-like hairs and they are supposed to be obviously branched, but the type (Horak 67/227) needs reexamining.
