Receptacle or stroma produced under the epidermis, black, gelatinous, homogeneous,
apparently quite simple, roundish, depressed. The sporidia
detaching themselves from the stroma, first burst through the epidermis
in the form of a little black cone, and then resemble a Stilbo-
spora; at length they are protruded in cirrhi of various forms, from h a lf
an inch to an inch or more in length, some being broad, thin, and
curved, while others are even quite filiform, and much curled and entangled
; after exposure to the atmosphere, the cirrhi become very
brittle and carbonaceous.
This is the largest species of Ncemaspora we are acquainted
with, and though not of frequent occurrence, is produced occasionally
in astonishing abundance. S o w e r b y observed some
trunks of Hornbeam in Hainault Forest in Fssex to be nearly
covered by it. Mr P u r t o n mentions that Mr R u f f o r d
