Cuba, and Central America. Strains differing from the above in the 

 absence of any yellow, thick-walled hulle-like cells are occasionally isolated 

 from soils. NRRL No. 1928, isolated from Arkansas soil, is representative. 

 In the absence of any yellow component, the color of these strains is more 

 accurately described as pale to light grayish-vinaceous-fawn (Ridgway, PI. 

 XXXIX). 



The name Aspergillus carneus is revived to cover the forms under con- 

 sideration since their most obvious identifying characteristic is the pale 

 flesh color of their massed conidial heads. It is the belief of the writers that 

 van Tieghem probably had in hand some member of this series when he 

 proposed the name S. carnea, although, due to the inadequacy of his descrip- 

 tion, it is now impossible to establish this point with certainty. In any case, 

 the name is excellently descriptive of strains commonly encountered, hence 

 its application in this connection. 



In describing Aspergillus carneus as a new species, Blochwitz (1933) 

 acknowledged the earlier use of this specific name by van Tieghem but dis- 

 regarded its validity. He undoubtedly applied it to a member of the 

 species as it is considered by us since he noted that it differed from A. 

 terreus (A. galeritus) principally in the flesh to rose color of its conidia. It 

 is believed that Blochwitz's A. niveus var. nubila (1934) likewise represented 

 a strain of A. carneus characterized primarily by conidia of darker rose, a 

 condition which in older cultures is frequently suggested by NRRL No. 

 1928 cited above. 



Oilman and Abbott in their "Summary of Soil Fungi" (1927) called atten- 

 tion to the repeated isolation, from Louisiana soils, of forms with the 

 "general morphology of the Aspergillus candidus group but producing bright 

 pink conidial heads." While the writers think the affinities of these forms 

 lie more with Aspergillus terreus (columnar heads, colorless conidiophores) 

 and Aspergillus fiavipes (elongate, irregular hiille cells) than A. candidus, 

 we have every reason to believe they were dealing with forms similar to 

 those here designated A. carneus. 



S. albo-rosea Sartory, Sartory, and Meyer (Ann. Mycol. 28: 358-359, PI. Ill, 

 fig. 1-6, 1930) apparently represents a member of this series. This is indicated by 

 the described coloration of colonies and more particularly by the detailed measure- 

 ments cited for it.

Synonym: A. eburneus Biourge, name attached to a culture received by 

 Thorn (No. 5402.1 : NRRL No. 515). 



Colonies upon Czapek's solution agar white, plane or radially furrowed, 

 rather slow growing, forming a dense felt of mycelium and conidiophores up
