[GS] Pileus 7-8 cm. diam., ochraceous to saffron yellow thickly dotted with small brown fibrillose scales, convex with down-rolled margin becoming broadly concave; flesh creamy yellow continuous with that of stipe. Gills sinuate, moderately distant, yellow staining brown at edges. Stipe 3 x 1 cm., creamy above, ochraceous at base, fibrillose striate. Spores 8-8.5 x 4.5~5um non-amyloid, ovoid, moderately thin-walled (Fig. 1/32, p. 10); copious white spore print. Cuticle of loosely woven hyphae about 5um diam.; scales are coremia-like tufts of parallel hyphae 3-5um, diam., with thickened walls which are rusty brown in transmitted light. HABITAT: in mountain forest, Waiopehu, 20.4.1947, E. Cone in Stevenson (type). [EH] Examination of the type material (together with additional collection made in New Zealand) justify this proposed combination. Spores oval to subcylindrical, neither amyloid nor dextrinoid, hyaline, smooth, 7-8.5 X 4—4.5 p.. Cheilocystidia conspicuous, thinwalled, with yellow plasmatic pigment in KOH, clamp connections present. Pleurocystidia none. [JAC] cheilos collapsed. Spores length=7.0–9.4µm (µ=8.2, σ=0.7), width=3.8–5.4µm (µ=4.4, σ=0.4), Q=1.6–2.2µm (µ=1.9, σ=0.2), n=16

Tricholoma ornaticeps Stevenson (29 D) Fig. 19 = Tricholomopsis ornaticeps (Stevenson) comb. nov. (Basionym: T. ornaticeps Stevenson, Kew Bull. 19: 17, 1964)

Examination of the type material (together with additional collection made in New Zealand) justify this proposed combination. Spores oval to subcylindrical, neither amyloid nor dextrinoid, hyaline, smooth, 7-8.5 X 4-4.5 µ. Cheilocystidia conspicuous, thin-walled, with yellow plasmatic pigment in KOH, clamp connections present. Pleurocystidia none.

Pileus 7-8 cm diam., ochraceous to saffron yellow thickly dotted with small brown fibrillose scales, convex with down-rolled margin becoming broadly concave; flesh creamy yellow continuous with that of stipe. Gills sinuate, moderately distant, yellow staining brown at edges. Stipe 3 x 1 cm, creamy above, ochraceous at base, fibrillose striate. Spores 8-8.5 x 4.5-5 µm, non-amyloid, ovoid, moderately thin-walled (Fig. 32); copious white spore print. Cuticle of loosely woven hyphae about 5 µm diam.; scales are coremia-like tufts of parallel hyphae 3-5 µm diam., with thickened walls which are rusty brown in transmitted light.
In mountain forest, Waiopehu, 20.4.19471 E-Cone in Stevenson (type).
Pileus 7-8 cm diam., ochraceus usque croceus, squamulis parvis brunneis fibrillosis dense sparsus, convexus, margine deflexo-revoluto, deinde late concavus; came cremeo-lutea cum stipite continua. Lamellae sinuosae, modice distantes, luteae, marginibus brunneo-tinctis. Stipes 3 x 1 cm, superne cremeus, basi ochraceus, fibrilloso-striatus. Sporae 8-8.5 x 4.5-5 µm haud amyloideae, ovoideae, parietibus modice crassis, sporarum cumulo copioso albo. Cuticula ex hyphis laxe intertextis circiter 5 µm diam. sistens; squamae e crinibus coremiiformibus hypharum parallelarum 3-5 µm diam. sistentes, parietibus incrassatis luce transmissa ferrugineo-brunneis.
Spores inamyloid
Typus: E. Cone in Stevenson 237
