MOXOVERTICILLATA

Species description based iipon Thorn's notes made on Biourge's type 

 (Thorn's No. 4733.58 — now lost from this collection) prior to 1928, and 

 upon comparative observations made during the current study on a number 

 of strains regarded as representative of the species. Among such cultures 

 may be listed NRRL 746, received in 1935 from Dr. Oscar W. Richards, 

 then at Yale University; NRRL 1196 received in 1940 from Dr. G. A. 



Fig. 59. Penicillium fellutanum Biourge, XRRL 746. A, B, and C, Two-week-old 

 colonies on Czapek, steep, and malt agars. D, Detail of penicilli, X 900. 



Ledingham, Ottawa, Canada; and numerous strains isolated by various 

 investigators from deteriorating military equipment in tropical and sub- 

 tropical areas and submitted to us for identification. 



Strains included within the species have the same morphology of conidial 

 structures, but show considerable individuality in rates of growth and in 

 cultural aspects — such as the compactness of superficial growth, color, 

 and in the specific character of the colony margin.
