Gen. Cuar. Root scutulate. Frond pencil-like. Stipes cylindrical, uni- 
cellular, nodulose, crowned with a tuft of obovoid, saccate, unicellu- 
lar ramuli, filled with grumous endochrome. Syores spherical, formed 
out of the contents of the ramuliimPotypnysa (Lamarck), from 
Tonv, many, and duaa, a sac. 
Radia scutata. rons penicilliformis. Stipes cylindraceus, unicellulosus, no- 
dosus, apice ramulis vesiceformibus obovoideis membranaceis succo grumoso 
repletis coronatus. Spore globose, perisporio hyalina rigide membranaceo 
donate, ex succo ramulorum demum evolute. 
Potypnysa Cliftoni ; stipes membranaceous, filiform ; ramuli very narrow, 
club-shaped.

Derscr. Root a small disc. Fronds tufted. Stipes 2-3 inches long, capillary, 
membranaceous or very thinly coated with carbonate of lime, distantly no- 
dulose, the nodes not much swollen, pierced with minute holes. Ramuli 
10-12, linear-cuneiform, about eight times as long as their greatest diameter, 
obtuse, at first filled with bright-green grumous matter; when mature, filled 
with spores. Spores spherical, with a tough hyaline perispore and full- 
green granular contents. The colour of the stipes is a very pale, of the 
ramuli a full grass-green The substance is softer and more flaccid than in 
P. Peniculus, but the frond scarcely adheres to paper in drying.

In our first volume, under Polyphysa Peniculus (Plate XI.), I 
named the present species and gave a brief description of it. 
I now complete its history, so far as I am able, by adding a figure 
and correcting a misstatement made from imperfect observation 
in the place above referred to. I had characterized it “xodis 
inperforatis.’ A more careful examination has revealed the
