‘Fairy Clubs’.

Morphology. The fruit-bodies producing basidia and basidiospores; simple, or compound; clustered (mostly), or solitary; clavarioid, erect-linear and unbranched, or erect-clavate and unbranched, or branched (without a distinct head); medium sized to large; 3–12 cm high; white or whitish and pink, or white or whitish and grey. The hymenium ribbed, or smooth. The basidia ‘unmodified’ (though with only two sterigmata); with only two (distal) sterigmata, these strongly curved. The basidiospores ballistosporic; hyaline; smooth; inamyloid.

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae monomitic. The generative hyphae inflated.

Ecology. Saprophytic. The fruit-bodies borne on the ground (humicolous). Found in grassy places, in coniferous woodland, in broad-leaved woodland, and in mixed woodland.

British representation. 7 species in Britain; Clavulicium, Clavulina, Membranomyces.

World representation. 38 species; genera 3. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Cantharellales.
