beneath it ; from them is developed the wall of the apothecium. In Ascoholus pulcherrimus 
the carpogonium consists of a vermiform body, which Tulasne calls the Scolecite. It is 
a branch of the mycelium, consisting of a row of short cells which are much broader 
than those of the mycelium. The adjacent threads put out small branches, polHnodia, 
the terminal cells of which attach themselves firmly to the anterior part of the scolecite. 
It is subsequently covered over, together with this fertilising organ, by branched hyphae 
apothecium is developed.

which spring from the neighbouring mycelium ; and a ball is thus formed in the middle 
of which lies the scolecite; and this finally grows into the apothecium. In all these 
cases the origin of the ascogenous filaments from the carpogonium has not as yet been 
observed, but according to analogy there can be no doubt that such is the case. 
In this group of the Discomycetes there are some individuals of which the mycelium 
forms conidia, and the unripe fructification is in inactive Sclerotium. Pe%tz.a Fuckeliana ^
