General Environment
This is a marine species.
Description
Algae form strap-shaped thalli which grow in a prostrate
manner attached by abundant 1-2 (-3.5) mm
long peg-like stipes produced from ventral surfaces;
algae are spreading and lobed with entire colonies to
4.0 cm broad and individual axes to 7.0 mm across;
branching occurs irregularly from margins; the lobed
branches slightly expanded distally and frequently
anastomosed; younger branches frequently overgrow
older blades; thalli are 250-300 µm thick with three
cortical cell layers and to five layers of medullary cells,the largest medullary cells measuring to
100 ¥ 200 mm; open cavities are common in the
medulla and medullary cells surrounding the open
spaces frequently support pyriform, to 8 mm long, or
elongated gland cells, to 14 mm long; tetrasporangia
are borne in irregularly shaped superficial sori, to 8 mm
across, on ventral surfaces; tetrasporangial mother cells
are borne on filaments of elongated cells and support
one to three tetrasporangia distally; tetrasporangia are
ovate and cruciately divided, measuring to 19 x 25 mm;
gametophytes are monoecious; carposporophytes
produce highly conspicuous hemispherical cystocarps
on dorsal surfaces which measure to 900 µm in diameter
and 600 µm high.
