Material is also being accumulated for carrying on a series 
of experiments in the culture and artificial inoculation of cer- 
tain species of the order mentioned, with the hope of gaining 
information concerning their life-histories. Many of the 
ascomycetes are connected in their life-histories with certain 
of the so-called imperfect fungi and very careful and critical 
study is necessary in order to determine this relationship in 
the various species.
