General Environment
This is a marine species.
Description
Rosy-red plants composed of irregular ligulate blades to 3.5 cm long from small discoidal holdfasts, stipes lacking; blades 135-250 µm thick, margins with irregular dentations of varying sizes; blade structure multiaxial with cell layers increasing in size from the outermost pigmented cell layer to the innermost non-pigmented cell layer connecting to the filamentous medulla; pigmented cortex composed of a single layer, the small cells globose to ovoid and sub-rectangular to irregular in surface view, transversely elongated in section, 7-12 µm in diameter; inner cortex of two layers of elongated cells increasing inwardly in size and stretching and thinning, some appearing stellate, the innermost 28-67 µm in length and connecting to the filamentous medulla; medulla composed of a spiderweb-like network of elongated filaments 2-5 µm in diameter, connected to occasional large darkly staining stellate ganglia; sporangia in scattered loose sori on blade surfaces under and displacing outer cortical cells, obovoid to ellipsoidal in shape, irregularly cruciately divided, 12-17 µm in diameter and 17-22 µm long; gametangia unknown.
Key Characteristics
Distinguished from the generitype, N. crouaniorum, by its COI-5P (GenBank MH777606) and rbcL (GenBank MH777609) sequence data, its ligulate blades with erose margins and smaller-sized tetrasporangia formed in sori.
