Rossbeevera griseobrunnea

Ciri dan struktur

Basidiomata hypogeous, small; pileus grayish white to grayish brown, surface bluing slightly when injured; hymenophore dull white to very pale blue in some portion when injured, finally rusty brown to dark brown at maturity; stipe absent; basidiospores 17–20 × (8–)9–12 μm, fusoid, ornamented with 4-longitudinal ridges (star-shaped in cross section), brown to dark brown; pileipellis a subcutis, with terminal elements short cylindro-clavate. Basidiomata hypogeous, 15–35 mm broad, 12–25 mm high, small, globose to subglobose, napiform, sometimes deformed or reniform, fleshy when fresh, firm when dry. Pileus very thin, surface glabrous to slightly velvety, shiny, grayish white to grayish brown, whitish at the lower portion, turning to pale blue when touched or injured. Hymenophore off-white, white to dull white when young, becoming pale blue to bluish in some parts/patches then rusty brown to dark brown when exposed to air for 3–5 minutes, often greenish brown around insect damage, firm, composed of minute, irregular locules, becoming partially collapsed with many small empty chambers when dried. Stipe absent. Stipe base present but reduced, white, dull white to grayish white, somewhat dendroid or as a small basal pad or rhizomorph. Odor and taste not recorded. Basidiospores [50/2/2] 17–20(−21) × (8–)9–12(–13) μm [mean = 18.5 × 10.5 μm, Q = (1.52–)1.63–1.91(–2.1), Q m = 1.81 ± 0.18] fusoid, ornamented with 4-longitudinal ridges (star-shaped in cross section) (up to 2.5 μm high), inamyloid, non-dextrinoid, brown to dark brown in KOH and H 2 O, thick-walled up to 2 μm thick, hilar appendages 1.5–3 μm long.
