This is a small species of somewhat characteristic form, 



approaching C. ivipressuhwi Elfv. in outline, but with less 



marked lobulations and more truncate apex, not to mention 



the prominent, almost peg-like, protuberance on each side of 



the vertical view. We have not yet seen it from England.
