1907] SHEAR & WOOD—ASCOGENOUS GLOEOSPORIA 265 
which seem to indicate that they may have some other function as 
well. They have frequently been found in our cultures, and occur 
also in cranberries that have been destroyed by the cranberry 
anthracnose. They vary considerably in size and shape, and the germ 
pore which is attributed to them is frequently indistinct or wanting. 
Most writers who have studied the ascogenous stages of these fungi 
have described them as without paraphyses. SHELDON'S has recently 
mentioned finding paraphyses in ascogenous perithecia produced 
from the apple. We have occasionally found organs surrounding 
the outer portion of the mass of asci which bear a close resemblance 
to the paraphyses of certain other pyrenomycetous fungi. A 
careful study of these organs shows that they are not intermingled 
with the asci, but are about the outer portion of the mass, next to the 
wall of the perithecium. In many instances they suggest aborted or 
malformed asci. In any case they would be more correctly called 
periphyses than paraphyses. Their rare occurrence would seem to 
indicate that they are of no great importance for taxonomic purposes. 
Since these organisms have been found to produce ascogenous 
perithecia in cultures, it would be expected that they would also 
produce them under natural conditions upon their host plants. The 
conidial forms are so numerous and so widely distributed that if the 
ascogenous forms occur often they would probably have been found 
and described by mycologists before now. DELAcRorx'® describes 
Glomerella (?) Artocarpi as found on Artocarpus leaves associated 
with Gloeosporium and Colletotrichum. The description and 
figures agree well with our ascogenous forms. Since beginning this 
investigation we have examined carefully various plants attacked by 
anthracnose in the hope of finding ascogenous perithecia under 
natural conditions. Thus far, however, we have been able to ‘find 
them in only two cases; that of the apple, which had already been 
reported by CLinTon (J. ¢.), and that of the rubber plant, Ficus elastica. 
The ascogenous perithecia are frequently found in abundance upon 
fallen leaves of the rubber plant, which have been attacked by the 
anthracnose, Gloeosporium elasticae Cke. & Mass. They agree in
