DopGE: RELATIONSHIPS OF FLORIDEAE AND ASCOMYCETES 165 
The ascogonium of Lachnea scutellata (Woronin, 96, W. H. 
Brown, 19) is not known to have a trichogyne. These authors ex- 
amined only the comparatively well-developed young fruits and 
were of course unable to determine the exact form of the archicarp. 
Miss Fraser’s latest paper (44) describes the trichogynes of 
Lachnea cretea (F1G. 1, F) as long and branching. No antheridium 
was found and Miss Fraser regards the form as wholly apogamous. 
The archicarps of L. cretea as described are very similar to those 
of L. abundans, which I have been able to grow and bring to ma- 
turity in great numbers in artificial cultures. In L. cretea the 
cross walls are sometimes perforated but later these perforations

are closed by thick pads. Miss Fraser believes that the antherid- 
ium has only recently disappeared. Branching trichogynes are 
not, however, confined to the Laboulbeniaceae as stated by this 
author. Stahl (86) figures a branched trichogyne in Collema 
microphyllum, Lindau (59) describes and figures such a form in
