P. glaucum to a special form, this does nol mend matters. Long 

 cultivation docs show, however, thai this organism is closely related 

 fco the one already described as P. camemberti. 95 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 

 Weigmann 88 and Wehmer 84 refer to this fungus as probably iden- 



Fra. 17. PeniciUium camemberti, vax. rogeri: o, 6, c, types of branching of conidial fructification ( < 900); 

 e, ripeconid J, h, j, k, sketches of conidial fructifications (> 140); 



/, in. germinal ion '>i conidia by several tul 



tical with P. camemberti. 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 character.
