Fruit bodies up to 8 cm high, broadly fusiform in outline, fragile and brittle when dry. Rhizomorphic strands slender, delicate, white. Stipe up to 3 cm long, erect, single or connate with 1-2 others, suede-like texture, white to cream color when young, becoming darker with age. Basal branches several, slender, erect, off-white becoming pale ochre to pale ochraceous cinnamon. Internodes diminishing in length gradually. Apices acerose, white. Odor musty, taste very musty. On conifer duff, common in Appalachian Mountain chain, across northern US and Canada, rare in Rocky Mountains and Pacific coastal areas, central and Northern Europe, reported from USSR. Hymenium deep slate green in FSW, unchanging with added ETOH. Stipe surface quickly blue in GUA. Globose to subglobose swellings common. Basidia narrowly clavate, 4-sterigmate. Spores broadly ovoid to broadly ellipsoid, slightly flattened and roughened in profile, ochre in prints. Cultural characters: colony on malt agar pale, off-white. Aerial hyphae and hyphae of advancing edge more or less straight, slightly thick-walled. Rhizomorphic strands with three types of hyphae: generative, skeletalized generative, and skeletal. Branch trama hyphae also with generative, skeletalized generative, and skeletal hyphae. Microscopically, skeletal hyphae of fruit body trama are very apparent. Rhizomorphic strands have generative, skeletalized generative, and skeletal hyphae. Neotype specimen: L - herti, Persoon, Germania, prope Göttingem, leg. Persoon, L no. 910.262-1000.
