On rotten wood in thickets. New Guinea, Lae Botanical Garden, 25 Sept. 1960.
Resupinate, subcoriaceous, rather dry, separable; margin minutel [sic] byssoid, determinate, white. Pores 70-110 µm wide, becoming c. 1 mm deep with rather gyrose and irpiciform thin dissepiments, arising as pores at the margin or as minute discrete hydnoid spines becoming confluent, white to pale cream and pale ochraceous buff; drying white pruinose from the cystidia. Flesh 50-150 µm thick, without a basal crust.Spores 2-2.5 x 1.3 µm, white, smooth, subcylindric ellipsoid, not amyloid. Basidia 8-10 x 3-3.5 µm, very small, clustered among the cystidia. Cystidia 25-60 x 4-7 µm, -15 µm overall, subclavate to obtusely subventricose, heavily encrusted, hymenial and subhymenial and projecting from the pore-edges; also with many subcylindric skeletal ends in the trama and thinly encrusted for lengths up to 100 µm; incrustation composed of minute crystals mostly within the thin outer membrane of the hyphal wall; not gloeocystidial. Hyphae dimitic, loosely interwoven in the flesh, irregularly longitudinal in the dissepiments, some more or less encrusted with granular or crystalline matter, not agglutinated, not dextrinoid, not swelling in KOH; skeletals 2.5-4 µm wide, walls -1.5 µm thick, aseptate, unbranched, apparently unlimited (traced for 400 µm), abundant, in the dissepiments mostly ending in cystidia, 2.5-3 µm wide on origin; generative hyphae 1.5-3 µm wide, clamped, with thin or slightly thickened walls, rather long-celled.
I collected this twice on the same day in Lae. If this fungus from New Guinea is correctly identified, then it has truly cystidiiform and encrusted ends to the skeletal hyphae and not merely encrusted hyphae as described by Ryvarden. Cunningham gave 'metuloids 50-150 x 6-10 µm' and 'skeletal hyphae 4-8 µm, walls 1-3 µm thick'. In the collections from Lae the skeletals were 2.5-4 µm wide with walls -1.5 µm thick but the stalks of the cystidiiform skeletal ends were 4-6 µm wide, and these may be what Cunningham measured.
This is not to be mistaken for T. ceraceicutis var. subochraceum with similar small spores but with pendent pileus, smaller regular pores, agglutinated hyphae and non-encrusted gloeocystidial skeletal ends.
