Alloclavaria purpurea: The Ultimate Mushroom Guide
About The Alloclavaria purpurea Mushroom
Alloclavaria purpurea is easy to identify by its cylindrical shape, clustered growth, and purple, purple-brown, or purplish-grey coloration. The fruiting body is made of numerous slender cylindrical spindles that may grow to a height of 12 cm (4.7 in), with individual spindles being 2–6 mm thick. The color is faded in older specimens. The spore print is white. It is reportedly edible but insubstantial. Fruit bodies are found in spruce-fir forests.
Formerly known as Clavaria purpurea, Alloclavaria purpurea (Hymemocheatales) is phylogenetically distinct from Clavaria (Agaricales). Its relatives in the family Repetobasidiaceae include Contumyces, Cotylidia, Loreleia, and Rickenella.
Other names: Purple Club Coral.
Alloclavaria purpurea Identification
Traditionally presumed to be saprobic--but Dentinger & McLaughlin (2006) suggest the possibility that it is mycorrhizal or associated with mosses (and given its range, I wonder whether it might be associated with spruces); growing in tightly packed clusters under conifers, often in moss; summer and fall (also winter in warmer climates); widely distributed in northern, montane, and western North America.
2.5-10 cm high; 2-6 mm wide; cylindrical to nearly spindle-shaped; unbranched; sometimes somewhat flattened, or with a groove or a twist; dry; soft; dull purple to purplish brown; paler at the extreme base; usually with a bluntly pointed tip.
Whitish to purplish; thin.
Iron salts are negative on surfaces.
Spores 8.5-12 x 4-4.5 µ; ellipsoid; smooth. Basidia 4-sterigmate. Cystidia up to 130 x 10 µ; cylindric; thin-walled. Clamp connections absent.
Alloclavaria purpurea Medicinal Properties
Antitumor effects. Polysaccharides extracted from the mycelial culture of A. purpureaand administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 80% and 70%, respectively (Ohtsuka et al., 1973).
