Small, globose, somewhat flattened, dull yellow, surface minutely

Gurr. Proc. Boy. Soc. (1857), y?. 119, with figs.
Growing gregariously on fragments of wood, on the sands by
the sea shore at Sketty, near Swansea.
Each individual presents the appearance of a small round somewhat flattened
body, of a dull yellow colour, and with an unevenness of surface caused
by numberless convolutions of theintegument. The diameter of the largest
did not much exceed Jth in. Externally with a strong resemblance to Dacry-
myces deliquescens. The integument is of considerable thickness formed of
several layers of cells, the outer large and rounded, the inner long and flat.
The asoi are broadly clavate, with a very short stem springing from threads
proceeding from tbe inner surface of the integument. They are absorbed at
an early period, and the sporidia form a dense mass. Sporidia globular,
colourless, furnished with long delicate sharp rays, projecting from the surface
in every direction. Each sporidium with an internal nucleus, or oil
drop. Spores « h Jh in. diameter.
