Clavariaceae

‘Fairy Clubs’, ‘Club fungi’, ‘Coral fungi’.

Morphology. The fruit-bodies producing basidia and basidiospores; simple, or compound; clustered, or solitary; not sparassidioid (q.v.); erect-linear and unbranched, or erect-clavate and unbranched, or branched (without a distinct head); small to very large; (2–)4–15(–20) cm high; brightly pigmented to not brightly pigmented; yellowish-brown, or light brown, or reddish-brown, or dark brown, or orange, or yellow, or blackish. The hymenium ribbed, or smooth. The basidia ‘unmodified’; 4-sterigmate (these straight or only slightly curved). The basidiospores typically uniguttulate; ballistosporic; white, or yellow, or olive, or brown; smooth, or ornamented (then echinulate).

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.

Chemical reactions. The context hyphae not xanthochroic; negative to ferric chloride.

Ecology. The fruit-bodies borne on the ground (mostly), or on dead wood (Clavaria fistulosa, sometimes). Found in grassy places, or in heathland, or in coniferous woodland, or in broad-leaved woodland, or in mixed woodland.

British representation. Clavaria, Clavulinopsis, Macrotyphula, Multiclavula, Ramariopsis.

World representation. 54 species; genera 5. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Agaricales.

Comments. Some Clavulinopsis species may be lichenized.
