Heinemannomyces splendidissimus Watling, Belg. J. Bot. 131(2): 135 (1998) Figs 6, 7
Description. Basidiomata medium-sized to large. Pileus 35–65 mm broad, at first hemispherical, then convex to applanate with age, sometimes depressed at disc, pileus surface covered by snuff brown, chestnut brown, purple-brown or grayish red (9B4, 9C4, 10CD4), woolly-floccose or woolly arachnoid velar remnants, usually darker at center, outer zone showing dull white to whitish background when the velar remnants vanish; margin incurved with slightly appendiculate velar remnants, often slightly lacerated; context 3–4 mm thick at pileus centre, elsewhere thin, changes from white to slightly reddening when cut or injured. Lamellae free, depressed around the stipe, broadly ventricose, bluish gray to leaden gray (19B3, 18C3) when young, becoming dark blue (19E4–7) to bluish gray (19D3–5) when mature; 3–4 tiers of lamellulae. Stipe 50–60 × 5–6 mm, central, cylindrical, slightly tapering towards the base floccose-squamulose all over the stipe, often vanish from handling or rain, with lighter shade of the pileus color, fistulose; stipe context slightly reddening when cut or injured. Annulus delicate, fugacious. Odor and taste unknown.
Basidiospores [60/3/3] (5.5–)6–6.5(–7) × 3.5–4.5(–5) μm, [mean length = 6.25 μm, mean width = 4.15 μm, Q = 1.42–1.55(–1.63),
Q m = 1.50 ± 0.043], ellipsoid to ovoid-ellipsoid, inamyloid, slightly thick-walled (0.5 μm), smooth, dark brown, grayish brown to slightly leaden gray in H 2 O and 5% KOH. Basidia 13–19 × 7–9 μm, clavate to broadly clavate, colorless or pale yellow in H 2 O and KOH, 4-spored, rarely 2-spored, with sterigmata up to 2 μm long. Lamellar trama regular to subregular, composed of thin-walled cylindrical hyphae 4–8 μm wide. Cheilocystidia 15–22 × 6–10 μm, abundant and scattered colorless, clavate to cylindro-clavate, sometimes narrowly fusoid, smooth, hyaline, thin-walled. Pleurocystidia absent. Pileus trama hyaline or pale yellow, 4–10 wide hyphae; refractive hyphae very common, 5–8 μm wide. Pileipellis (woolly-floccose squamules on pileus) a complex of hyphal types, interwoven, loosely arranged, brick red in mass but hyaline to light red or pale red individually when observed in H 2 O and KOH, sometimes slightly puffy or swollen in some portion of some hyphae, smooth, thin-walled, cylindrical hyphae 4–10 μm wide; terminal elements measuring 20–50 × 4–10 μm. Stipitipellis similar to pileipellis but with paler color and slightly narrower hyphae measuring 3–8 μm wide. Stipe trama composed of parallel hyphae 4–9 μm wide, hyaline; refractive hyphae sometimes present 3–5 μm wide. Clamp connections not found in any tissue.
Habit, habitat and distribution. Solitary, scattered on the ground; known from Malaysia, Thailand, and now China.
Specimens examined. CHINA, Guangdong Province, Shantou City, Nanao Island, 8 May 2015, Iqbal, Tai-Hui Li & Ting Li (GDGM 46633); same location, 9 May 2015, Iqbal, Tai-Hui Li & Ting Li (GDGM 46634, GDGM46635).
海氏蘑菇属
Heinemannomyces Watling Belg. Journ. Bot.131:133,1999担子果群生或单生。菌盖小型,幼时半球形,成熟后多平展,表面密被絮状至绒状鳞片;边缘延生或悬垂有菌幕残余。菌褶离生,初期灰蓝色,后变深蓝色至灰黑色;菌柄中生,中下部被絮状至绒状鳞片;菌环往往撕破而消失。孢子印深蓝色至深紫罗兰色。菌褶菌髓为规则型。担孢子褐色至淡褐色,光滑,无芽孔。褶缘囊状体常见;侧生囊状体阙如。菌盖表面鳞片由不规则排列、不易断裂的菌丝组成。锁状联合阙如。

讨论:海氏蘑菇 H.splendidissimus 的主要特征是菌盖表面密被灰褐色至褐色絮状至绒状鳞片,菌褶灰蓝、深蓝色至灰黑色,菌柄中下部密被灰褐色至褐色絮状至绒状鳞片,孢子印深蓝色至深紫罗兰色,担孢子椭圆形至长椭圆形,5.5~7x3.5~4μm,无芽孔,光滑。
Watling(1999)报道该种有锁状联合,本卷作者在研究的标本中并未见锁状联合。作者未研究该种的模式标本,但分子系统发育分析显示,上述研究标本(如 HKAS 60216和90465)与Velling等(2011)提供的H.splendidissimus的DNA序列几乎是完全相同的。
