329. The carpogone inside of the pericarp gives rise, by 
branching, to one or more large cells filled at first with 
granular protoplasm, which soon forms two to eight spores 
(Fig. 82). Upon its outer surface the 
spore-fruit develops long filaments 
(known as appendages), probably for 
holdfasts. In some genera: these ter- 
minate in hooks (Fig. 81); others are 
dichotomously branched; still others 
are needle-shaped; while many end 
irregularly. The spore-fruits remain 
during the winter upon the fallen

330. The Herbarium-mould (Euro- 
tium) is a near relative of the Blights. It is common on 
poorly dried specimens in the herbarium, and also on de- 
caying fruits, wood, etc. It sends up vertical branches, 
which swell at the top and bear a great number of small 
protuberances (the sterigmata, A, c, st, Fig. 83), each of 
which produces a chain of conidia. 
331. The sexual organs appear a little later than the 
conidia. The end of a branch of the plant becomes coiled 
into a hollow spiral (A, as, Fig. 83), which constitutes the 
carpogone. From below the spiral an antherid grows up- 
ward, and brings its apex in contact with the upper cells 
of the carpogone (B, Fig. 88). 
332, After fertilization, other branches grow up around 
the carpogone, and finally completely enclose it, as in the 
Blights described above (C, D, Fig. 83). In the mean 
time, from the cells of the enclosed carpogone branches
