Habitat:
Solitary, growing under Dipterocarpaceae or mixed deciduous forest.
Description:
Basidiomes subglobose to ellipsoid, slightly compressed, hard, subepigeous 19-42.0 mm diam, dry, with woolly, adpressed covering forming felty, adpressed triangular to hexagonal scales, denser and more fluffy towards base where they are intermixed with date-brown to sepia rhizomorphs, splitting into concentric zones which fuse towards uppermost, exoposed parts, with thick, complex exoperidium, expanding to become star-shaped and then 40-100 mm broad, tough, surface often encrusted with soil particles, odour strong, penetrating, pleasant. When mature exoperidium buff to snuff-brown, squamulose, consisting of at least 3 distinct layers 3-5 mm thick when fresh, contracting to <1 mm when dry, leathery, splitting into 6-8 broad, stellate rays, innermost layer varying from buff to brownish, extensively scaly cracked to give almost regular pattern. Endoperidium shortly stipitate, globose to subglobose, 18-32 µm diam., white at first, becoming buff to hazel when mature, very fluffy-fibrillose, even velvety opening by apical, irregular tear and lacking defined peristome. Gleba purplish chestnut becoming umber to date-brown when mature, lacking columella. Exoperidial suprapellis 70-90 µm, brownish, consisting of interwoven, periclinal to perpendicular, thin- or thick-walled hyphae 4-7 µm broad, with central lumen and walls 1-2 µm thick. Exoperidial mediopellis, fibrous, 600 µm broad of interwoven periclinal to orthogonal hyphae 5-7 µm broad with hyaline, continuous lumen and walls 1-2 µm thick and becoming more parallel at junction with subpellis. Exoperidial subpellis pseudoparachymatous, 1050-1100 µm broad of hyaline, parallel to anticlinal, thick-walled hyphae with walls 1-2 µm thick. Clamp-connections absent in exoperidium. Endoperidium consisting of brownish, interwoven, unbranched, aseptate hyphae, 5-8 µm broad with continous lumen and walls 1-2 µm thick, clamp-connections absent. Capillitium of long, unbranched, interwoven, hyaline, aseptate threads 4-7 µm broad and lacking clamp-connections. Basidiospores globose, 6-9 µm diam, including ornamentation, brown.
