[GS]Pileus 3-4x5 cm. diam., fuscous to greyish sepia, overlain with radiating loosely anastomosing darker fibrils, concave to infundibuliform with a waved margin, sometimes with a small central umbo, sometimes opening at centre to stem cavity; flesh thin, greyish. Gills decurrent, thick, shallow, some forking, greyish. Stipe 2-3 cm. x 2-3 mm., fuscous to dark greyish sepia, smooth to cottony striate, rather tough, hollow, bulbous at base. Spores 7-8 X 5-6um, amyloid, smooth, moderately thin-walled (Fig. 1/33, p . 10). Hymenophoral trama regular with hyphae up to 10um, diam. Strong sour smell. HABITAT : on fallen wood, Eastbourne, 4.6.1949, Stevenson (type); Tararuas, Levin, 18.6.1949, Stevenson. [EH]Cuticle of repent, cylindrical, interwoven hyphae forming a cutis, with epimembranous pigment, clamp connections none. Spores oval, hyaline, neither amyloid nor dextrinoid, smooth, 5.5-7 X 5um.Cystidia none. [JAC] spores most certainly amyloid, thus imemdiately confirming later records as Pseudoclitocybe foetida. Gill edge dark macroscopically but without cystidia. Pileus an unclamped cutis with brown encrusting pigment. 4-spored basidia but spores very variable in size. length=6.2–8.5µm (µ=7.3, σ=0.71), width=4.9–6.4µm (µ=5.5, σ=0.42), Q=1.1–1.6µm (µ=1.33, σ=0.12), n=24 (minus apiculus). Basidia 40 x 10um. Interesting that Stevenson's notes in the packet indicate she originally thought it was (pseudoclitocybe) cyathiformis. Separated from C. fistulosa by clearly amyloid spores, membrane pigment, more equal and larger basidia and unclamped cap tissue.
 

Cantharellula foetida Stevenson (29 D) Fig. 10 = Omphalina foetida (Stevenson) comb. nov. (Basionym: C. foetida Stevenson, Kew Bull. 19: 18, 1964).
