Scléroderme en forme d'oignon

(Fig. 5) Description: — Basidiomata small to medium-sized, 28 – 54 mm in diameter, 23 – 33 mm in height, subglobose to tuberiform, mostly sessile, rarely shortly stipitate; odor unknown; taste unknown. Peridium leathery, 1 – 2.5 (3) mm thick, merino white (# F 9 F 5 EC), lotus-root orange (# F 5 E 9 D 9) to butter orange (# F 2 DF 8 F), usually without a color change after damaged or turning reddish after damaged, with thin, flaky, concolorous or dull dirty orange (# EBD 087) to light brown (# B 39966) squamules. Gleba compact at first, becoming pulverulent, flint brown (# 736960) to dull black (# 0 B 0 C 0 E). Basal rhizomorphs abundant, whitish to yellowish. Basidiospores {40 / 2 / 2} 12.5 – 16 (17.5) [14.26 ± 1.17, 13.50] µm in diameter including ornamentation, mostly globose, rarely subglobose, thick-walled, with echinulate to subreticulate ornamentation 1 – 2 µm high, brownish to purplish, often surrounded by remnants of placental cells. Basidia collapsed. Gleba trama composed of 2 – 5.5 μm wide, thin-walled to slightly thick-walled, nearly colorless to slightly brownish, compact, moderately branching, subregularly arranged to interwoven hyphae without clamp connections. Peridial squamules composed of 3 – 6 μm wide, slightly thick-walled, brownish, moderately compact, moderately to frequently branching, subregularly arranged to interwoven hyphae without clamp connections. Peridial trama composed of 3 – 6.5 μm wide, slightly thick-walled, nearly colorless to slightly brownish, compact, moderately to frequently branching, subregularly arranged to interwoven hyphae without clamp connections.
