232 A MANUAL OF THE ASPERGILLI 



tiania, 1885. Described as showing smooth globose spores, 3.0 to 3.5m and a single 

 series of sterigmata in culture, up to 20m in length, but with some secondary sterig- 

 mata seen in the original material. The separation of this from A. niger appears 

 questionable. 



Aspergillus pyri English n. n., in Doctoral Thesis, State College of Washington, 

 Pullman, Wash. pp. 76-78, 1940; cited in abstract. A form described as showing a 

 single series of sterigmata 14.4 to 19.2m by 3.6m and spinulose conidia 3.6 to 4.8m in 

 diameter. In personal correspondence of June 1943, English stated that as a result 

 of continued study of this strain and the finding of double sterigmata, he ques- 

 tioned the desirability of maintaining the species designation. 



SYNOPSIS OF SPECIES PROPOSED BY MOSSERAY 



Biourge, who was a discriminating collector, accumulated 63 strains of 

 "black" (or related) Aspergilli for each of which he could see sufficient 

 individuality to warrant preservation. Mosseray, working in Biourge's 

 laboratory, studied these strains, attempted to establish species lines among 

 them, and proposed new specific names for all forms which he believed 

 undescribed. With the whole 63 strains in parallel culture, all bearing the 

 names applied by Mosseray, Biourge and Simonart were inclined to with- 

 draw part of Mosseray's new species names, a position with which the 

 writers heartily agree. Nevertheless, to present one concept of the range 

 of variation confronted by the student of this group, Mosseray's synopsis 2 

 has been translated with minor emendations, and is herewith presented. 



Mosseray's Synopsis 



A. Conidia 6 to 10m in diameter, rough; vesicles subglobose; primary sterigmata often 

 100m or more in length; colonies jet-black. 



a. Sporulation more or less dense ; heads large ; reverse fumose or very dark olive 



with mycelium more or less wrinkled. 

 Conidiophores 2, 4, or even 6 mm. long; sclerotia present in "natural" media 



A. carbonarius (Bainier) Thorn and Currie 



Conidiophores 1 to 2 mm. long; sclerotia not reported A. pulchellus (Speg.) 



Thorn and Church, Syn. S. acini-uvae Caballero 



b. Sporulation less dense; heads small, also with very small heads with single
