物种介绍

摄于福建
来源：哎呦

该种的主要特征是子实体小型；菌盖褐色，水浸状，干后略污白色；菌幕浅褐色，易脱落；菌褶直生至略弯生，浅褐色至深褐色；孢子色淡，淡黄褐色，芽孔明显但小；褶缘囊状体一般囊状至纺锤状，顶部钝。

相似物种

该种和可可色小脆柄菇Candolleomyces cacao宏观特征上相似，但后者的褶缘囊状体腹鼓状至宽烧瓶状，芽孔在5%KOH溶液中不明显，分布范围在热带地区。Psathyrella lacuum的淡褐色菌幕上有大量分散蛛网状的白色纤维；Psathyrella cordobaensis的菌盖小（10mm宽），芽孔不明显，褶缘囊状体袋状至椭圆形（Tolgor Bau & Jun-Qing Yan 2021）。

Candolleomyces subcacao T. Bau & J.Q. Yan, sp. nov. MycoBank No: 839231 Fig. 2
Holotype. China. Henan Province: Bird Island, Nanwan Lake, Xinyang City, 32°06'43.32"N, 113°06'03.06"E, 124 m elevation, 17 July 2016, Tolgor Bau, JunQing Yan, HMJAU37807 (holotype!)
Etymology. Referring to its morphological similarity to C. cacao.
Diagnosis. Differs from C. cacao in having a distinct spore germ pore.
Description. Pileus 11–35 mm, spreading hemispherically to planar, hygrophanous, brown (7E7–7E8), striate up to halfway from the margin or indistinct, becoming slightly dirty white (7B1–7B2) upon drying. Veil pale brown (7A5–7B6), thin, fibrillose, falling off easily. Context thin and very fragile, dirty white (7B1–7B2), approximately 1.0 mm thick at the centre. Lamellae 3.0–4.0 mm wide, moderately close, adnate to slightly adnexed, pale brown (C3–C4) to dark brown (7D6–7E6), saw-toothed under 20× magnification. Stipe 40–50 mm long, approximately 2.0 mm thick, white (7A1–7B1), hollow, equal, smooth, with white fibrils (7A1–7B1) at the base. Odour and taste indistinct. Spores 6.8–8.0(8.8) × 3.9–4.9 μm, Q = 1.4–1.8, ellipsoid to oblong-ellipsoid, profile slightly flattened on one side, rarely phaseoliform, inamyloid, smooth, pale yellow-brown, darkening in 5% KOH, pale brown, germ pores distinct, but small, approximately 1.0 μm wide. Basidia 17–22 × 6.1–7.3 μm, clavate, hyaline, 4-spored. Pleurocystidia absent. Cheilocystidia 22–36 × 9.8–14 μm, scattered to moderately numerous, various, utriform to fusiform, with an obtuse to broadly obtuse apex, rarely subcapitate or clavate, ovoid, thin-walled. Trama of gills irregular. Pileipellis consisting of 2–3 cells in the deep layer of the subglobose cell, 20–37 μm wide.
Habit and habitat. Solitary to scattered on rotten wood in oak forest.
