Description
Single, or occasionally a few, blades arising from often long stipes on small discoidal holdfasts, blades not adhering well to paper; rosy-red blades simple, to 1.3 cm tall, obovate, elliptical to subspherical in outline, margins entire; blades 40-100 µm thick in vegetative portions, medulla comprised of a compact cavity with few to many intertwining, elongate filaments, 1.5-4.5 µm diam. and large, oddly lobate to stellate swollen ganglial cells; medulla giving rise to a 2-(3-) layered cortex, subsurface cells small, subglobose to flattened reaching 10 µm diam., outer cortical cells 3-6 µm diam., irregularly globose to elongate in transverse section, irregularly angular to rounded in surface view; dioecious, subglobose auxiliary cells in ampullae, 10-17 µm diam., produced from medullary filaments; carposporophytes immersed in blades, globose, 100-250 µm in diam., with stretched involucral filaments, dramatically swelling both blade surfaces to 270 µm thick; carposporangia subglobose to irregularly elongate, 9.5-14.5 µm diam.; spermatangia formed in extensive sori on both blade surface from elongated spermatangial mother cells produced directly or on one-celled pedicels produced from outer cortical cells, spermatia ovoid to ellipsoidal, 1 µm diam.; tetrasporangia ellipsoid, cruciately divided, 10-12 µm diam., 9-18 µm long, clustered over the surface of both blade surfaces and compressing adjacent cortical cells.
