Bres.
Study description
General: Belongs to the Morchella elata clade, characterized by paler pileus color ranging from grey to yellowish-ochre, with regular elongated pits separated by straight longitudinal ridges.
Asci: Cylindrical, hyaline, 8-spored, uniseriate, 250-350 x 18-23 µm, inamyloid in Melzer's reagent.
Paraphyses: Scarce, cylindrical, septate, shorter than asci, up to 200 µm long, 7-10 µm wide, apices swollen up to 12 µm.
Ascospores: Ellipsoid, smooth, hyaline, measuring 20-30 x 13-20 µm in this collection (literature standard: 20-26 x 13-18 µm), smooth and homogeneous internally without vacuolar contents.
Herbarium voucher: JTP2466/25.
