Cryptococcus neoformans

Abstract

Conclusions

These observations would seem to indicate that Cryptococcus neofor-mans and Lipomyces starkeyi may be one and the same organism, and that it is frequently isolated from the soil. Thus another of the fungi pathogenic to man may take its place in that large and important class of the Ascomy-cetes. It remains but to find ascospores in a strain isolated from a human case. A large number of strains from various sources must be studied and comparisons made both as to virulence and other characteristics. For absolute proof that the structure represents a true ascus one would need to know how the spores are delimited. The final and complete story will be told only by cytological investigations.
