Summary: Features include 1) resupinate growth on dead wood, 2) a fruitbody that is reddish, red-brown, ocher, bluish, or violaceous, the surface smooth to tuberculate, often with a filling of crystals in the warts which finally emerges, 3) a margin that is fringed to indeterminate, 4) spores that are allantoid, smooth, inamyloid, and colorless, 5) cystidia that are awl-shaped to spindle-shaped, thin-walled, and not encrusted, and 6) a monomitic hyphal system, the hyphae with clamp connections.
Microscopic: SPORES 4.5-5 x 2-2.5 microns, slightly allantoid, smooth, inamyloid, colorless, with droplets; BASIDIA 4-spored, 25-28 x 3.5-4 microns, narrowly clavate, with basal clamp connection; CYSTIDIA 40-50 x 3-3.5 microns, subulate [awl-shaped] to fusiform, smooth, thin-walled; HYPHAE monomitic, 2-3 microns wide, thin-walled to thick-walled, with clamp connections; older fruitbodies with accumulations of crystals, (Breitenbach), SPORES 5-6 x 2-2.5 microns, suballantoid, smooth, inamyloid, acyanophilic, thin-walled, containing 1-2 oil droplets; BASIDIA 4-spored, 22-26 x 3.5-4 microns, subclavate, standing in a dense palisade, with basal clamp connection; CYSTIDIA "varying in number and often difficult to find, in other cases quite frequent", 40-50 x 3-4 microns, subulate [awl-shaped], thin-walled, not encrusted; HYPHAE monomitic, with clamp connections, "embedded into a conglutinate tissue", hyphae in the subhymenium 2-3 microns wide, thin-walled, and vertical, hyphae in the basal layer 3-5 microns wide, horizontal, +/- parallel, "with walls somewhat thickened and swelling in KOH"; in older fruitbodies often big heaps of CRYSTALS, "finally emerging through the hymenium", but these crystal eruptions absent in some specimens, (Eriksson)
Notes: Phlebia livida has been found in BC, WA, OR, ID, AB, NS, ON, PQ, AL, AZ, CA, CO, LA, MD, MT, NC, NH, NM, NY, PA, TX, VT, and WI, (Ginns). It has also been found in Denmark, Finland, Norway, Sweden, and central and southern Europe, (Eriksson). It occurs in Switzerland and Asia, (Breitenbach).
