1914] THAXTER—ASCHERSONIA 309 
sistency of the different species pointing to this conclusion. It has 
been suggested that they might be imperfect conditions of species 
of the ascomycetous genus Hypocrella, with which, owing to their 
similar mode of life, they are apt to be associated; and this sug- 
gestion is still further supported by the fact that when a flat hemi- 
spherical type of Aschersonia has become blackened by age and 
exposure, or colored by the sooty disintegrated material of accom- 
panying Capnodia, which grow on the excreta of various hemip- 
terous insects, it is often difficult to distinguish the two by their 
§t0ss appearance. Definite information in regard to this con- 
nection, however, has hitherto been lacking, and, as already men- 
tioned, I have found no record of observations which might throw 
light upon it. P. Hennincs in the ASCHERSON Festschrift, where 
he discusses the validity of the generic name and certain other 
matters, states that he was informed by ZIMMERMAN, whose con- 
tributions to the knowledge of Javan entomogenous fungi are well 
known, that although he sought for them with care he never 
€ncountered any individuals which showed indications of an 
ascosporic fructification. 
During the past year (1912~1913) I had an opportunity to spend 
Some months on the islands of Grenada and Trinidad, and having 
the matter in mind made a special effort to discover this proble- 
matical ascosporic form. In the locality where I remained during 
Practically my whole stay in Grenada, Aschersoniae were by no 
means numerous, and only three species were met with. These 
forms, moreover, were comparatively rare, although one of them, 
the well known and characteristic though very variable A. turbi- 
"ata, was found several times. A few specimens of this species 
In the original gathering from a certain locality showed, when 
carefully examined, certain not very conspicuous but suspicious 
looking pustules, containing cavities unlike those of the pycnidia, 
which appeared to be young perithecia, and by a systematic search 
in the same spot I was able to obtain numerous specimens bearing 
the perfect form fully and characteristically developed. Unluckily, 
the majority of these specimens were accidentally destroyed by 
fire, together with many other mycologic treasures, but a sufficient 
humber were saved, both dry and in alcohol.
