Helvella infula , Schaeff., Fung. Bavar. 4: Ind. 105, 1774; Seaver, Mycologia 12:4, pi. 1, 1920; Seaver, The North American Gup-Fungi (Operculate), p. 251, pi. 42. 1928.

 Description: The whole shape is similar to Agaricales. It possesses stalk and pileus but lacks pores and gills. Pileus saddle-shaped and occasionally forms two lobes, not disturbing in average, reaching a diameter of 4-5 cm, margin reflexed and free repand to the stem. Surface striate or contorted, color varying from brown to dark brown and almost brownish black, inside smooth and dark red. Stalk up to y.5-11 cm high, and diam 3-9 mm (not including the wall; wall 1.5-3mm thick) from base to the pileus, tapering and hollow, lacunose, one or two chambers, and strongly fluted on the surface, color paler than the pileus, nearly ochraceous. Asci, clavete, about 214-216 μm long, diam of 10-18 μm. Color of the apices of the asci not changed by iodine including eight ascospores, 1-seriate, partially 2-sweiate or irregular. Spores smooth-walled, ellipsoidal, 8-12 × 16-20 μm, contaonong two or sometimes one oil drop. Paraphyses slender but enlarged at their apices forming hemispheres 5-10 μm in diam with septa.

Specimen No. 201, at Ah-Li Shan in Chiayi, Altitude about 2200 m (April 5, 1981, K. Y. Chen). All specimens described above have been deposited in the Mycology Laboratory, Institute of Biological Sciences, National Taiwan normal University, Taiwan, R.O.C.

 Note: According to Ainsworth et al. (1973), the shape of the ascocarp of Gyromitra is gyros like the brain, while Helvella is saddle-shaped. Therefore, our species should be identified as Helvella infula.
