Unexpanded basidiomata epigeous, yellowish white (4A2), citriform to lacrimiform, 5–9 × 3–8 mm, surface tomentose to rugulose when mature, not encrusted. Subiculum white (4A1), covering the substrate, producing exudate in some basidiomata. Expanded basidiomata saccate, 3–8 mm high × 8–10 mm wide. Exoperidium splitting into 5–6 revolute, triangular rays, 2–3 mm diam, non-hygroscopic. Mycelial layer yellowish white (4A2) to orange white (5A2), surface rugose, tomentose to papery when mature, not encrusted, persistent. Fibrous layer papery, white (4A1). Pseudoparenchymatous layer brown (6D4) to orange grey (5B4), persistent. Endoperidial body greyish brown (6F3) to orange grey (5C3), subglobose to depressed–globose, 3–5 × 4–6 mm sessile, glabrous. Peristome fimbriate, with folds on apex, delimited by a line brownish grey (6F2) to greyish brown (5C3), lighter than endoperidium, mammiform, < 1 mm high. Columella ampuliform, 4.5 × 0.6 mm, central, inconspicuous, orange white (5A2). Subiculum composed of hyaline, filamentous, slender hyphae, 0.6–1.7 μm diam, dextrinoid, strongly sinuous. Rhizomorphs composed of hyaline, slender hyphae, 1.2–2.5 μm diam, surface encrusted, lumen not evident, surface covered by crystals, with narrow oblique prism shape. Mycelial layer formed of hyaline, thick-walled (0.5–1.2 μm diam) hyphae, 5.3–10.1 μm diam, dextrinoid, surface not encrusted, lumen evident, branched apex. Fibrous layer formed of hyaline, thick-walled (0.6–1.3 μm diam) hyphae, 5.1–9.5 μm diam, surface encrusted, lumen non–evident. Pseudoparenchymatous layer formed by brownish hyphal cells, subglobose to pyriform, 32.6–59.5 × 23.4–40.8 μm, thick–walled (0.9–1.8 μm diam). Eucapillitium dark brown, 2.7–4.0 μm diam, thin–walled (0.5–0.8 μm diam), surface slightly encrusted, no lumen evident. Basidia yellowish, thin-walled (0.4–0.7 μm), clavate, pyriform to lageniform, 9.2–18.7 × 7.5–15.5 μm. Basidiospores brownish, globose to subglobose, 3.8–5.1 × 3.7–4.9 μm (x = 4.3 ± 0.3 × 4.2 ± 0.3, Qm = 1.03, n = 90), ornamentation conspicuous in LM, densely verrucose under SEM, medium warts (0.43–0.91 μm high) with planar tips.
The species is known from several localities in the Neotropics, thus, we suggest this species to be categorized as Least Concern (LC).
This species has a Neotropical distribution (4 countries).
There are 10 records according to original description, most of them from Brazil (5).
Population Trend: Uncertain
This species has a Neotropical distribution. Found in the biome Tropical & Subtropical Moist Broadleaf Forests of the Brazil (Alto Paraná, Atlantic forests, Bahia coastal forests, Pernambuco coastal forests, Pernambuco interior forests, Uatumã-Trombetas moist forests) and the Guiana shield (Suriname and French Guiana, Guyanan lowland moist forest ecoregion), and in the Caribbean (Guadeloupe, Martinique). Cespitose basidiomata grow on abundant subiculum, on decaying wood
In Brazil, this species is found in the Atlantic Forest, a hotspot, and in the Amazonia (currently being deforested at the highest rates in the last decades).
Reports in Brazil are from protected and unprotected area.
It is important to better understand the species distribution in the neotropics.
