　Description： Pileus 3-4 cm broad, saddle-shaped with 2 or 3 lobes to irregularly convoluted in the center, margins appressed to the stipe then expanded; hymenium ivory to cream colored, pale to medium ochraceous when dried, rugulose over the disc; undersurface darker than hymenium when fresh, pale ochraceous when dried, pruinose and briefly ribbed near the stipe apex. Stipe enlarging downward to subclavate, 4-7 cm long, 5-10 mm broad at the apex, whitish or obscurely tinged with gray at the base, pale cream colored when dried, hollow, surface deeply lacunose, ribs angular to acute. Asci eight-spored, cylindrical, 255-290 × 16-19 μm, J- in Melzer,s reagent. Ascospores 20-24 × 13-15 μm , oblong-elliptic, with 1 central oil globule, walls smooth, slightly thickened. Paraphyses 9-10 μm broad above, hyaline with a yellow refractive content in Melzer,s, medium to pale blue in cotton blue, apical cell longer than 100 μm. Medullary excipulum 300-490 μm broad, textura intricata, colorless, hyphae 3-4.5 (-6) μm broad; ectal excipulum 150-275 μm broad, textura angularis, colorless, outermost cells catenuliform in long fascicled tufts, nearly colorless, evenly blue in cotton blue, end cells cylindrical to subclavate, 20-43 × 9-15 μm, walls slightly thickened. Stipe surface similar to pileus ectal excipulum.

　Note： Of the genus Helvella section, Helvella Dissing with stipe longitudinally sulcate-costate is the oldest and well known. It is typified by the common species H. crispa and H. lacunosa Afz.: Fr.. But the latter is greyish brown, and its head is more lobed than saddle-shaped. Dissing(1966) noted that this species has a northern distribution range near the latitude of 60°- 62°N, but he did not mention the southern range. The specimens were found in the area of 23°- 24° N at the altitude of 1700m.
