August.—Frond of an olive-brown colour and cartilagineo-membranaceous
texture, but adhering
cut nearly to the base into
to paper when dry, broadly flabelliform,
3— 5 cuneate primary segments, and those
again copiously divided into numerous, irregular, but more or less
linear ones. Fructification scattered over both surfaces of the frond,
consisting of clavate pedicellate capsules, arranged in small clusters.
These capsules Dr. Greville aptly compares to the little black Fungus
so common on rose-bushes in gardens, the Phraemidium mucronalum.

ceiltric lines (rarely spots), mostly on one surface of the frond.
