Since this is the form given prominence in cheese studies by the work of Georges Roger,21 it seems most natural to regard it as a variety of the former species and designate it by Roger's name. In Lafar's Handbuch der Technischen Mykologie, Professors Weigmann88 and Wehmer84 refer to this fungus as probably iden-. Fra. 17.

However this may appear from examina- tion of the lit etat life alone no one actually familiar with the cultures will claim such identity. If the possession of colorless spores be regarded as a case of albinism, this form may perhaps be regarded as a variety of P. camemberti. It has been kept separate and re- mained constant in culture for several years, It would seem, there- fore, equally proper to regard it as a different species were it not so closclx associated with /'. camemberti in every other Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thom, Charles, 1872-1956.
