Description
Thalli saxicolous, prostrate, dorsiventrally organized, firm and smoothly textured, brownish-red; blades originally reniform to transversely ovate, 1-3 cm wide, initially attached by short, submarginal holdfasts, the primary blade then proliferating new blades from the margins, some fusing with other blades in the same plane; blades overlapping and affixed to one another by occasional secondary holdfasts issued from the ventral surface; blades 400-450 microns thick with nearly squared-off margins, medulla loosely filamentous with long, thin, mostly periclinal filaments 2-6 microns in diameter and flaring somewhat at the branching ends; cortex 6-8 layered with irregular to sub-globose large inner cortical cells 45-55 microns diameter, grading to smaller outer cortical cell layers, the surface cells irregularly rounded to spherical and small, 3-6 microns in diameter; tetrasporangia obovate, irregularly cruciately divided, 10-15 microns diameter, 20-35 microns long, amongst elongated outer cortical cells in raised surface patches on the ventral surface; thalli dioecious, spermatangia produced from transformed elongated outer cortical cells; spermatia spherical to elongate, 0.5-1 micron diameter; carposporophytes scattered and embedded in the dorsal cortex, to 125 microns diameter; carposporangia subglobose to irregularly angled, 7.5-12.5 microns diameter.
