Olive green to olive brown, growing in depressed mats: stems 
0.06 mm. in diameter, not closely appressed to the substratum, 
loosely and irregularly pinnate, the branches widely to obliquely 
spreading, tending to become parallel in old mats, similar to the 
stem: leaves imbricated, the lobe widely spreading, slightly convex, 
somewhat falcate, ovate, 0.35 mm. long, 0.3 mm. wide, arching 
partially or wholly across axis, antical margin strongly outwardly 
curved to the apex, postical margin straight or slightly curved, 
forming an obtuse angle with the keel, apex broad, rounded to very 
obtuse, margin entire or vaguely and irregularly sinuate; lobule 
conforming to the type normal for the genus,* though sometimes 
poorly developed, inflated throughout, ovate, 0.1 mm. long, 0.08 
mm. wide, keel arched, very slightly roughened from projecting 
cells, free margin straight or slightly curved when explanate, 
involute to apex and arched in natural position, apical tooth short 
and curved, tapering to a blunt point, hyaline papilla in a slight 
depression, sinus lunulate; cells of lobe plane or a little convex, 
averaging about 9u at the margin, I5u in the middle, and 18 X 
15u at the base, walls apparently uniformly thickened, the pits 
very indistinct; ocelli mostly two (rarely three to five), situated

broadly cuneate to rounded at the base, bifid about one half with 
suberect triangular divisions, acute (rarely obtuse) at the apex, 
and an acute sinus, margin entire or nearly so, rarely with vague
