Species Information
Summary:
Features include 1) growth spread out on conifer wood (especially pine), generally bent outward to form caps that are often shingled, 2) caps that are cream to gray when old, tomentose, and zonate, the spore-bearing surface dark purple to violet brown, with radiating folds that may be interrupted and may anastomose to form small pits, 3) spores that are oblong to oval, smooth, inamyloid, and colorless, 4) a monomitic hyphal system, the hyphae without clamp connections.
Microscopic:
SPORES (4.4)5.6-7.2(8.8) x (2)2.2-2.8(3) microns, oblong to oval, in side view "adaxially flattened or slightly concave, or sometimes basally bent", smooth, IKI-, colorless, colorless or quickly pale blue in lactic-blue, thin-walled; BASIDIA 17-30 x 4-5.5 microns, narrowly clavate to cylindric; CYSTIDIA none; HYPHAE monomitic, context hyphae generally horizontally woven, colorless, "predominantly thick-walled, occasionally branched at a right angle, simple-septate", 3.5-6.5 microns wide, adjacent to subhymenium "the hyphae are often thin-walled, closely packed, with yellow granules interspersed"; subhymenium "of thin-walled hyphae, closely packed, frequently branched", up to 3 microns wide, "oriented parallel to the long axis of the basidia", (Ginns(12))

Habitat and Range
SIMILAR SPECIES
Byssomerulius corium grows primarily on hardwoods, and has a pale orange-yellow to orange-brown spore-bearing surface (but intergradations in color can cause difficulty in assigning the species name), (Ginns(12)). Gloeoporus taxicola may be similar in color but has deeper folds, a thicker broader margin, and narrow spores 1-1.5 microns wide, (Ginns(12)). Byssomerulius albostramineus may also be violaceous or dark purple but has small, allantoid or basally bent spores, (Ginns(12) under Meruliopsis corium).

on bark and wood of conifers, primarily Pinus (pine), and rarely on hardwood; associated with a white rot; in the Alaska to Idaho area collections May through September, (Ginns(12)), primarily on Pinus, also Alnus, Picea, Salix, (Ginns(5))
