Summary:
Features include tiny brown cups on deer dung, the undersides brown and smooth with a network of brown hyphae, stem absent or short, and microscopic characters.
Pseudombrophila cervaria is found in WA (Kanouse), NY and the United Kingdom, (Brummelen(2)), and Denmark, Finland, Norway, and Sweden, (Hansen, L.). Oluna Ceska has reported Pseudombrophila cervaria (W. Phillips) Brumm. from Vancouver Island in BC on deer dung.
Upper surface:
0.15-0.3cm across, about 0.1cm high, at first nearly spherical then more or less scutellate; chestnut brown or purplish brown; margin "thin, crenulate or fimbriate", (Brummelen), 0.15-0.3cm across, cup-shaped; chestnut brown or purplish brown, (Hansen)
Underside:
chestnut brown or purplish brown, smooth and covered with a network of brown hyphae, (Brummelen), "with very pale, adnate hairs", (Hansen, L.)
Stem:
without a stem or with a short, stem-like base, (Brummelen), sessile or stem 0.1cm long; no sclerotium, (Hansen, L.)
Microscopic:
spores 14.4-17.0 x 7.0-8.5 microns, elliptic or oblong-elliptic, smooth, at first colorless, often finally with pale yellowish brown contents, without oil droplets or granules when mature, uniseriate in ascus; asci 8-spored, 150-175 x 10-12.5 microns, cylindric with very short stalk, wall not blue with Melzer''s reagent; paraphyses about 2 microns thick, filiform, not or only very slightly enlarged, 2-3 microns thick at tip, colorless "but near the tip often with pale brownish walls, with intercellular, amorphous, purplish-brown pigment covering the tips", septate, branched especially in the upper parts; hymenium about 150 microns thick, hypothecium about 25 microns thick, of closely compacted cells 4-10 x 3-7 microns; flesh up to 900 microns thick in central part, of small isodiametric cells 7-14 microns in diameter and of large oblong cells 19-53 x 5-12 microns, colorless; excipulum of subglobular, angular or slightly elongated cells 8-20 microns in diameter (textura angularis or textura globulosa), near the base up to 75 microns thick, (Brummelen), spores 14.5-18.5 x 7-9.5 microns, (Hansen, L.), spores 15-17 x 7-9 microns, colorless; paraphyses filiform, not enlarged at tips, colorless, often branched in upper part; asci abruptly attenuated at apices, (Kanouse)
