Notoscyphus grollei sp. nov. in Bitterfeld amber rather than the extant Notoscyphus lutescens (Lehm. & Lindenb.) Mitt. [2015/8]

Diagnosis

Ca. 3 mm long, pale yellowish to reddish brown, sterile gametophyte fragment. A second shorter gametophyte fragment represents either a single intercalary branch of the large plant or a second unbranched gametophyte (base not visible but basalmost leaves smaller than subsequent ones). Stem cylindrical, 80–100 μm in diameter, strongly degraded, the preserved cortical cells rectangular, ca. 15–25 x 25–45 μm, papillose, with thin to slightly thickened walls. Rhizoids colorless, ca. 7–10 μm in diameter, in bundles at the base of underleaves. Leaves succubously inserted, remote to slightly imbricate, bent upwards or obliquely spreading, flat or weakly concave, ovate rectangular to elongate-triangular, up to 0.36 mm long and 0.25 mm wide, apex rounded or truncate, rarely emarginate, margins not recurved, dorsal bases not or shortly decurrent, ventral bases not decurrent. Lamina cells +/- isodiametric, 25–35(–40) μm in diameter, thin walled, possibly with nodulose trigones, often distinctly mammillose, with numerous small, rounded to slightly elliptical papillae. Underleaves spreading, smaller than stem, deeply bifid, with uniseriate lobes.
