The micromorphology displayed by one north american strain (Illinois) of Manilia albicans is identical to the classical morphology of Endomyces albicans Vuill. or E. Vuillemini. From the study of the strain, the conclusion is that the very abundant and early production of acrogenous spherical, double-walled chlamidospores were considered as asci, only for the superficial analogy with true species of the Genus Endomyces. The original Vuilleminian strain, conserved up to-now appeared as one asporogenous, while no exhaustive proof of the original sporogenicity were presented by Vuillemin. In conclusion, our strain, with the Vuillemin's strain and E. Cruzi (and probably E. fulmonalis and E. bonaerensis) has been considered as a variety [var. Vuillemini (Landrieu ex Cast, et Chalm.) nobis] of Mycotorula albicans (Rob.) Lang. et Tal.
