Summary:
Features include 1) a cup-shaped to flattened fruitbody with the upper surface dark brown to black, and the underside the same color or paler, 2) absent stem, 3) growth on burnt ground, and 4) microscopic characters including smooth spores.

Microscopic:
spores 8-10 microns in diameter, "round, smooth, typically with several small oil droplets", (Arora), spores reaching 10-12 microns in diameter, smooth, colorless or slightly yellowish, rather thick-walled, usually containing one large central oil droplet, 2-seriate becoming 1-seriate; asci reaching a length of 350 microns and a diameter or 15-18 microns, cylindric or subcylindric in upper part, tapering in lower part into stem-like base; paraphyses, slender, rather abruptly widened in upper part, densely granular within, reaching width of 7 microns, showing a tendency to stick together in bundles, (Seaver), spores 8-10 microns in diameter, round, smooth, with granular contents; asci 190-200 x 9.5-11 microns, J+; paraphyses filiform [thread-like], slightly expanded at tip, up to 4 microns wide and covered by an amorphous yellow-brown incrustation; medullary excipulum of textura globulosa and filamentous cells, up to 2 microns wide, ectal excipulum of textura globulosa, the cells smaller than in medullary excipulum, (Tylutki), spores 8.5-9.5 microns in diameter, smooth, (Hansen), spores 8-9 microns in diameter, smooth, colorless or faintly brownish, containing numerous small oil droplets, (Dennis)

Notes:
Plicaria endocarpoides is found at least in BC, WA, OR, ID, CA, and MT, (Larsen), New Zealand and the United Kingdom, (Dennis), and Denmark, Finland, and Norway, (Hansen).
