Description
Plants erect and lax, saxicolous or conchicolous, dark rosy-red, 2-3.5 cm tall, arising from small discoidal holdfasts, at times secondarily attached by rhizoidal outgrowths from margins; axes flattened, 2-3 mm broad in main axes, tapering to 1 mm in lesser branches, 300-450 µm thick, alternately and suboppositely branched to four orders from the margins, appearing pinnate, often arcuate, with marginal linear-lanceolate proliferations in lower portions, apices acute; axial row obvious in cross-section, cells 7-20 µm in diam., to 500 µm long, surrounded by a medulla of large hyaline, transversely compressed cells to 200 µm wide, decreasing in size from center outwards to a two-layered, densely pigmented cortex, surface cells forming an incomplete, rosette-like layer around subsurface cortical cells, rosette cells occasionally bearing short, unicellular hairs to 500 µm long; rosette cells 5-30 µm in diam., subglobose to highly irregular in surface view, subsurface cells subglobose to irregularly ellipsoidal in surface view; tetrasporangia ellipsoidal to obovoid and arcuate, zonately divided, 28-43 µm in diam., 50-75 µm long, in extensive irregular sori covering the main axes and branches, occasionally restricted in small, distinct sori in youngest portions; monoecious, spermatangia globose to obovoid, formed on rosette cells in small rosettes throughout, 2-3 µm in diam.; procarpic, carpogonial branches 3-celled, carposporangia subglobose to obovoid, 17-30 µm in diam., formed in terminal chains on gonimoblasts surrounding large-celled tissues; cystocarps marginal, rarely on laminae, hemispherical with globose carposporophytes, 425-625 µm in diam., surrounded by stretched cortical cells and producing thin pericarps without ostioles.
