DopGE: RELATIONSHIPS OF FLORIDEAE AND ASCOMYCETES 187 
arise from the parent hyphae of both sex organs, as well as from 
the stalk of the archicarp. I have not found that the stalk of the 
antheridium gives rise to any enveloping hyphae. At first these 
sterile hyphae grow upward from all sides of the ascogonium. 
They are very coarse strands which branch profusely, some scat- 
tering branches wandering up and over the trichogyne and ascog- 
enous cell, but at no time is there a weft or layer of hyphae com- 
pletely surrounding the ascogenous cell such as is formed in A sco- 
bolus furfuraceus, A. carbonarius, etc. The inner branches of the 
enveloping hyphae give rise to the paraphyses. I have been able 
to trace connections between the enveloping hyphae that arise

from the parent mycelial hyphae and the paraphyses in many 
cases, but I believe that many paraphyses likewise arise from the 
branches of the ascogonium stalk. In sections of young apothecia 
just visible without a lens we find immediately above the ascog- 
€nous cell a number of somewhat parallel hyphae running 
Vertically upward. Some of these are ascogenous hyphae, others 
are paraphyses or hyphae which have pushed in among the 
ascogenous hyphae and which by further branching will give rise 
to paraphyses. The two kinds are easily distinguished by the 
larger nuclei of the ascogenous hyphae and the fact that in 
Sections 10 » or more thick the ascogenous hyphae are easily
