Habitat:
On soil.
Description:
Basidiomata coralloid, 50–110 mm high × 30–50 mm broad, solitary or caespitose, loosely branched, very pale purple when fresh, brownish gray when dried. Branches 3–7 mm diam., round in cross-section, polychotomous, dichotomous, or rarely trichotomous in direction to the apex, primary lower branches 5–7 mm diam., very pale purple, secondary branches 3–6 mm diam., very pale purple, terminal branches 2–5 mm diam., grayish purplish red, axils V-shaped, tips acute, white, fresh soft, fragile, and brittle. Stipe 10–20 × 2–3 mm, solid, grayish brown. Context yellowish white, slightly viscid, rather tough at the base of the stipe. All tissue unchanging where cut or bruised. Odor not distinctive.
Basidiospores 4.5–6.0 µm long, 3.0–4.0 µm wide, excluding ornamentation, ellipsoid, coarsely echinate, hyaline in 5% KOH. Ornamentation acute warts or spines 0.5–1.2 µm long. Basidia primarily 2- to 4-spored, clavate, barrel-shaped, approximately 11–26 × 5.5–11.0 µm with sterigmata 3–5 µm long, clavate, hyaline, clamped. Cystidia absent. Hyphal system monomitic; generative hyphae with clamp connections. Context hyphae hyaline, thin-walled, 1.25–6.25 µm diam., ampulliform septa 5.0–5.5 µm diam. Hymenium ≤ 37.5 µm thick. Subhymenium ca. 25 µm thick, composed of hyphae, 1.25–6.25 µm diam., thin-walled. Context with subparallel arranged hyphae 2.0–10.0 µm diam., thin-walled, branched, septate with clamped.
