Description:Phallales G. Cunn.
in Proc. Linn. Soc. N.S.W. 56:3 (1931).
Fruitbody comprising a gleba, borne on a receptacle, initially enclosed by a peridium, and remaining so in Hysterangiaceae; at first hypogeous, globose to ovoid, either indehiscent or epigeous and dehiscent; with conspicuous rhizomorphs. Peridium smooth, membranous, pale, often loose and detersile. Gleba embedded in a gelatinous matrix, attached to the peridium either basally or by a series of peridial sutures; pale ochraceous to olive-green or brown, deliquescent, autolysing into a foetid mucilage. Receptacle present in epigeous species, subtending the gleba, pseudoparenchymatous, spongy and rapidly expanding on release from within the peridium, ranging from cylindrical and resembling a stipe, to stellate or reticulate.
Hyphal system monomitic, often gelatinized; generative hyphae with clamp-connexions. Basidiospores elongate ellipsoid to oblong-cylindrical, hyaline to pale greenish brown, smooth, with a thin to slightly thickened wall, basally truncated by a broad hilar attachment. Basidia small, tetra- to octosporic. Hymenophoral trama regular, hyaline, gelatinized. Peridiopellis an epicutis, at times pseudoparenchymatous, usually subtended by a gelatinous mesoperidium. Development angiocarpic. Type family: Phallaceae Corda.
The Phallales fruitbody opens in epigeous species to release a rapidly expanding sterile structure, called the receptacle, which bears the spore-producing gleba above ground. The gleba autolyses to a mucilaginous slime and develops an extremely unpleasant, foetid odour in order to attract flying insects which enable spore dispersal. The Hysterangiaceae E. Fisch., or Stinkhorn Truffles, contain the hypogeous genus, Hysterangium Vittad., which is not considered further here, but a full account may be found in Pegler, Spooner & Young (1993).
