Subhymenium 30–170 µm broad, of textura globulosa-intricata . Asci (204.6–) 239.8– 242.4 (–310) × (13–) 14.9–15.1 (–18.6) µm, pleurohynchous, subcylindrical, eight-spored. Ascospores [90/3/ 3 in H 2 O] (20.8–) 23.3–24.3 (–26.7) × (10.3–) 11.3–11.7 (–12.5) µm, ellipsoid to broadly ellipsoid, subfusoid, smooth, hyaline, [Q (1.85–) 2.03–2.13 (–2.36), Q av 2.08 ± 0.15]. Paraphyses 3–4.3 µm, filiform, septate, hyaline. Apex of paraphyses 5.4–9.9 µm</p><p>Habitat and known distribution: Solitary or scattered on the ground in broad-leaved forest.</p><p>Additional specimen examined: SOUTH KOREA, Jeju, Jeju-si, 1100-ro 2073, elev. 1,055 m, 9 July 2023, S.Y. Park, KH027 (KA24-1348), SOUTH KOREA, Jeju, Jeju-si, 1100-ro 2073, elev. 1,055 m, 9 July 2023, S.Y. Park, KH028 (KA24-1349)</p><p>Notes: In the phylogenetic analysis, sequences of Helvella griseomacropus formed an independent branch with strong support within the Macropus lineage. Helvella macropus and Helvella submacropus were represented as the most closely related taxa. One of the distinct traits of H. griseomacropus is its grey-colored ascomata, which distinguishes it from H. macropus, whose ascomata are yellowish-brown to pale greyish-brown (Dissing 1966). H. submacropus is very similar to H. griseomacropus in many traits, including color, size, and microscopic features; however, several notable differences were observed. The color of H. griseomacropus is paler than that of H. submacropus, and its apothecia are more plane to discoid in shape (Fig. 2B), rather than shallowly cupulate as in H. submacropus (Li et al. 2023) . Microscopically, H. griseomacropus has a distinct subhymenial layer composed of textura globulosa-intricata . In addition, the ascospores of H. griseomacropus are longer (20.8–26.7 × 10.3-12.5 µm vs. 17–23 × 10-13 µm), and the average Q value (length/width ratio) is markedly higher than in H. submacropus (2.08 ± 0.15 vs.1.73 ± 0.12).</p></div>	https://treatment.plazi.org/id/AC44C14FCB79096118ADFF4C974A3D80	Public Domain	No known copyright restrictions apply.

Cap 1.0– 3.5 cm high, 1.3–3.6 cm broad, laterally compressed cup-shaped, margin deflexed to even, free from stipe. Hymenium grayish brown to dark brown. surface smooth. Receptacle surface concolorous with the hymenium, covered with whitish tufts. blunt ribs nearly absent or covering approximately one–third of the receptacle surface. Stipe 1.0– 5.2 cm high, 0.3–1.3 cm broad, cream to white at the base, gradually becoming dark brown toward the apex and concolorous with the receptacle surface, tapering upwards, glabrous but covered with tufts at the apex, ribbed and furrowed, ribs blunt, exhibiting both single- and double-edged forms, with anastomosis present.</p><p>Ectal excipulum 70–110 µm broad, of textura angularis, 10.4–28.4 × 6.3–21.6 µm.

Park &amp; H.P. Choi, KH088 (KA25-0480).</p><p>Notes: Helvella koreana belongs to the Solitaria lineage and forms a sister relationship with Helvella taiyuanensis in the phylogenetic tree. However, morphologically it shows a closer resemblance to Helvella solitaria . The apothecia of H. koreana remain laterally compressed cup-shaped throughout development, whereas those of H. taiyuanensis are irregular to saddle-shaped, and H. solitaria develops from a compressed form when young to a regular cup shape at maturity.</p><p>Ascospore dimensions of H. koreana (17.8–22.1 × 13–16 µm) are comparable to those of H. solitaria (19–24 × 12–15 µm) (Dissing 1966), but larger than those of H. taiyuanensis (15–18.9 × 11.3–13.4 µm) (Liu 1985). The stipe of H. koreana is cream to white and glabrous, becoming concolorous with the receptacle surface toward the apex and bearing scattered tufts. In contrast, H. solitaria has a whitish to grayish-white stipe, and H. taiyuanensis is white to cream, both showing uniform coloration from base to apex, with H. taiyuanensis bearing a single rounded longitudinal ridge (Wang et al. 2019).</p></div>	https://treatment.plazi.org/id/AC44C14FCB78096118ADFC9E93A43770	Public Domain	No known copyright restrictions apply.
