Description:Ileodictyon cibarium Tul. apud Raol in Ann. Sci. Nat., Bot. sër.3, 2: 114 (1844).
Clathrus cibarius (Tul.) E. Fisch. in Jahrb. K. Bot. Gart., Berlin 4: 74 (1826).
Selected descriptions: Cunningham (1944: 110, pl.XII-XIII); Dring (1980: 56, fig. 17); Reid & Dring (1964: 293).
Selected illustrations: Fuhrer (1985: 101 & 104); Reid & Dring (1964: fig.1).
Diagnostic characters: receptacle globose, white with radially symmetrical lattice; soon detached from volva; receptacle arms tubular, not spongy.
Immature fruitbody subhypogeous, subglobose to ovoid, up to 7 cm diam., consisting of an unexpanded receptacle with characteristic concertina-like folding, within a membranous peridium, attached by branching, white mycelial cords. Peridium off-white, with reticulate grooves, rupturing irregularly at the apex. Gleba olivaceous brown, mucilaginous, covering inner surfaces of receptacle, sometimes finally hardening and contracting to restricted zones. Receptacle sessile, pure white, translucent, more or less globose but becoming flaccid, 8-10(-25) cm diam., composed of a hollow sphere of anastomosing arms forming isodiametric, polygonal meshes (c. 10-30), showing a radial symmetry with no apico-basal differentiation; arms c. 1 cm diam., not thickened at intersections, hollow, simple tubular; detached from the peridial volva. Odour foetid or recalling Camembert cheese.
Basidiospores 4.5-7 x 2-2.8 µm, ellipso-cylindrical, subhyaline with a greenish brown tint, smooth, with a thickened wall.
Habitat: at the edge of woodland clearings or on disturbed soil.
Distribution and frequency: very rare and introduced, usually occurring in winter months. First British record from Hampton, Middlesex, in 1955 (Reid 1985), with several later collections found within a 5 km radius, in Middlesex (Hampton, Heston, Hounslow) and Surrey (Thames Ditton), all in garden localities. An apparently unrelated find, also in a garden, is known from near Ipswich, Suffolk. Not recorded elsewhere in Europe. Extremely common in New Zealand, less so in Australia (Cunningham, 1944)
Other remarks: the fruitbody may be adapted to tumbling in the wind to aid dispersal and distribution. Expansion can be extremely rapid once the receptacle is released, and a detailed account of this phenomenon is provided by Colenso (1893).
