of protoplasm that begins adjacent to the centrosome and con- 
tinues progressively. 
Faull has procured additional cytological evidence for placing 
the Laboulbeniales among the true Ascomycetes. It should be 
noted, however, that the method of ascogonous formation here 
described is entirely unlike anything known among the asco- 
\ 
mycetes. Although he has heretofore been inclined to view the 
ascus as having been evolved from the zoosporangium of the 
Oomycetes, he now admits that there may be some grounds for 
relating the Ascomycetes to the Florideae. “ Such features as a , 
uninucleate antheridium, the possibility of proliferation of sper- 
matia from the same antheridium, and the exogenous types of 
spermatium organization suggest similar phenomena in the rusts, 
many Ascomycetes, and in the Florideae.”

Maire’s Remarks on Some Hypocreaceae 
Under the title “ Remarques sur quelques Hypocreacees R. 
Maire discusses a number of species belonging to the genera Pyx- 
idiophora, Peckiella, Hypomyces, and Nectriopsis, the last being 
a new genus. In this paper a number of data are given which 
add to our knowledge of the North American Hypocreales. 
In the “ Hypocreales of North America the writer made 
Hypomyces boletinns Peck a synonym of Hypomyces chryso- 
spermus (Bull.) Tul. with a note that the spores in the North 
American specimens examined were smaller than usually indi- 
cated for European specimens. On this difference Maire retains 
the American form as a variety of the European. At the time 
this note was made it was the opinion of the writer that the dif- 
ference in size of the spores was due to immaturity of the plants 
examined. It still seems likely that this apparent difference 
would fade out if a careful comparison could be made of a suffi- 
cient number of plants from both America and Europe. The 
species is common on Boletus but the conidial phase is more 
common than the perfect and is identical in the European and
