Notes

Fayodia cystidiosa Stevenson (29 D) Fig. 6 = Mycena cystidiosa (Stevenson) comb. nov. (Basionym: F. cystidiosa Stevenson, Kew Bull. 19: 46, 1964)

This is a very peculiar species of the genus Mycena. The conspicuous cheilo- and pleurocystidia are apically ornamented with irregular thick-walled, hyaline excrescences. Spores 8.5-12 -X 6-7.5 µ, oval, hyaline, weakly amyloid, smooth.

Fayodia cystidiosa G. Stev. 1964

Description

Pileus 6-12 mm diam., light brown with dark brown umbo, indistinctly striate and fluted, somewhat velvety, margin paler and frilled; flesh white beneath umbo, fawn above gills. Gills sinuately adnexed, cream, some with dull pink blotches, moderately distant, bristling with cystidia. Stipe 6-8 cm x 1-2 mm, cream above, brown below, smooth, hollow, brittle, with spreading hyphal hairs at base. Spores 9-10 x 7 µm, amyloid, thick-walled, inner wall sieve-like. Cheilo- and pleurocystidia 25-40 x 8-13 µm, very abundant, thick-walled, weakly amyloid (Fig. 36). Hymenophoral trama and tissue of pileus pseudo-amyloid.

Habitat

Amongst litter, Wellington Botanic Garden, 2.6.1949, Stevenson (type).

Latin

Pileus 6-12 mm diam., laete brunneus, umbone fusco-brunneo, indistincte striatus et sulcatus, subvelutinus, margine pallidiore lacinioso; caro sub umbone alba, supra lamellas hinnulea. Lamellae sinuato-adnexae, cremeae nonnullae sordide puniceo-maculatae, modice distantes, cystidiis horrentes. Stipes 6-8 cm x 1-2 mm, superne cremeus, inferne brunneus, laevis, cavus, fragilis, basi pilis hyphalibus patentibus instructus. Sporae 9-10 x 7 µm, amyloideae, parietibus crassis, pariete interno cribriforme. Cheilo-et pleurocystidia 25-40 x 8-13 µm, copiosissima, leviter amyloidea, parietibus crassis. Trama hymenophoralis et textura pilei pseudo-amyloid

Notes

Half-sized spores were also seen in this collection. The species may be found to have 2-and 4-spored basidia, as it appears to have 2 sizes of spores. Although the spores are smooth in outline they appear as though rough because the inner wall is irregular.
