Easily known when perfect by the grey frosted perithecia,^ which are deeply
umbilicate beneath, by collapsing and separate, together with the epidermis,
from the inner bark ; sometimes, however, they are retained by the ba,rk,
and in th at case the mealiness is seen only with great diffionlty. Ostiola
bursting through the cuticle and making the matrix rough, like a nutmeg
grater, pierced with a round, depressed orifice.—M.J.B.
