WE put this among the Sphæpria from its resemblance, although it seems destitute of the common covering of the genus. It bursts the cuticle in so rough a manner as to give the stick it grows on the appearance of a rasp or file.

THE mouth of this Sphæria perforates the cuticle, and the edges turn back upon it, forming a broad whitish border: sometimes these have 2 or 3 perforations in them, and 2 or 3 mouths beneath.

ABOUT half of each sphærule rises, swelling the cuticle hemispherically, and giving it a dark greyish tinge.

THE sphærule is nearly round, buried in the upper part of the cortex. The mouth perforates the cuticle, and has round it a blackish stain.

THIS bursts through the cortex, forming a mouth under the cuticle, with a spreading black circle round it, occasionally perforating the cuticle with a smaller circle or stain round it.

THE crustaceous cover of this Fungus spreads on the outside of the wood, in parts forming little pustulate sphærulæ, with somewhat pointed mouths.

ALWAYS on the outside of the wood, or nearly so; sometimes confluent, roughish and hard.
