Cantharellula fistulosa G. Stev. 1964

[GS] Pileus 2.5-3.5 cm. diam., ochraceous buff overlain with sparse darker fibrils, moist at first drying subfibrillose, infundibuliform, opening at centre to stem cavity, margin down-turned, waved and becoming split; flesh thin, ochraceous. Gills decurrent, moderately distant, rather shallow, sometimes forking, ochraceous buff with a whitish bloom. Stipe 4-6.5 cm. x 2-3 mm., ochraceous, smooth, completely hollow, with a bulbous base. Spores 6 x 4um, amyloid, rather thin-walled, smooth (Fig. 1/37, p. 10); basidia 30 x 5um. Hymenophoral trama subregular with hyphae up to 5um diam. HABITAT: on fallen rotting wood, Korokoro, 1.5.1948 [EH] Spores oval, hyaline, amyloid, smooth, 5-6 X 3.5-4 um.; cheilocystidia club-shaped, thin-walled, 20-55 X 10—18 um, with clamp connection at the basal septum; cuticle of interwoven, cylindrical hyphae, forming a cutis, with scattered dermatocystidia-like cells. [JAC] cap tissue quite tough and elastic once revived (NH4OH). Stem base with a pad of radiating fibrils. Trama quite clearly sarcodimitic with long aseptate thick-wallled hyphae. Pileus a clamped cutis with brown and colourless vesicles (certainly Hydropoid). Vesicles usually broader than figured by Horak.The basidia are long. spores amyloid (neither strong nor weak). Cheilocystidia are present, collapsed, and generally cylindrical with occasional pleurocystidia-like - spherical/utriform. Occasional brown globose/utriform pleurocystidia present. Caulocystidia present on upper stem and like pleurocystidia and cap vesicles, some thick walled. Placement in Pseudoarmillariella (near Cantharellula in Lichenomphalia group) is understandable but more likely Clitocybula which is supported by sequence data from a morphologically similar collection. C. grisella is possibly just an immature version of this. Spores length=5.5–7.1µm (µ=6.4, σ=0.45), width=3.5–5.0µm (µ=4.1, σ=0.38), Q=1.3–2.0µm (µ=1.55, σ=0.14), n=30. Basidia 30 x 6 um.

Cantharellula fistulosa Stevenson (29 D) = Pseudoarmillariella fistulosa (Stevenson) comb. nov. (Basionym: C. fistulosa Stevenson, Kew Bull. 19: 18, 1964)

Spores oval, hyaline, amyloid, smooth, 5-6 X 3.5-4 µ; cheilocystidia club-shaped, thin-walled, 20-55 X 10-18 µ with clamp connection at the basal septum; cuticle of interwoven, cylindrical hyphae, forming a cutis, with scattered dermatocystidia-like cells.
