THE ASPERGILLUS CANDIDUS GROUP 211 



S. alba Bainier (Bull. Soc. Bot. France 27: 30. 1880) was isolated from oatmeal, 

 and while incompletely described, obviously represents a member of the A. candidus 

 series. Several publications present elaborate comparative tables to separate strains 

 accepted as A. Candidas and A. alb us, but the many strains obtainable vary into each 

 other so completely that little or no basis for separation exists in fact. 



A. albus Wilhelm (Beitr. z. Kenntn. d. Pilzgattung Aspergillus, Inag. Diss. Strass- 

 burg, p. 69, 1877) was described with characters which clearly ally it with A . candidus 

 but without sufficient differences to separate it from other members of this group. 



S. blanc-jaune Bainier nomen nudum — A culture from Bainier's collection received 

 by Thom under this name (No. 4640.490) represents a somewhat diminutive but other- 

 wise typical member of this series. 



S. albo-lutea Sartory and Meyer (Cited by Blochwitz in Ann. Mycol. 31: 73. 1933). 

 Conidia were reported as turning yellowish in age. This character is common to 

 many members of the group and has been so noted by Wehmer (1889-1901), Thom and 

 Church (1926), and others. Retention of the species name is not warranted. 



A. basidiosepla Sartory, Sartory and Meyer (Ann. Mycol. 27: 317-320, PI. 7. 1929) 

 apparently represents a member of the A. candidus series with comparatively long 

 (28 to 30m) primary sterigmata which in age are characteristically septate. This char- 

 acter, which appears also in some members of the A. niger and A. ochraceus groups, 

 however, is not sufficiently unique to warrant specific separation. 



A. niveus var. major Blochwitz (Ann. Mycol. 32(1/2): 86. 1934). Described as 

 showing vesicles globose, rarely oboval, or pear-shaped entirely covered with radiat- 

 ing sterigmata which are rarely absent toward the base; closely growing conidio- 

 phores 2 to 2.5 mm. high. These characters suggest relationship with A. candidus 

 rather than A. niveus. 



A. okazakii Okazaki, in Centralb. f. Bakt. etc., 2 abt., 19, p. 481-484, taf. I. 1907; 

 see also Centralb. f. Bakt. etc., 2 abt., 42, p. 225. 1914. This is cited by Saccardo 

 in Syll. 22: 1260. 1913, as S. okazakii Saito but apparently without adequate ground 

 for attributing the name or description to Saito. 



Colonies described as white to sulphur yellow; conidiophores hyaline, straight or 

 sinuate, smooth or asperulate, 200 to 500m by 8 to 12m figured as undulate, especially 

 toward the base, with walls 2 to 3m thick; heads 80 to 100m in diameter; vesicles 12 to 

 40m in diameter; primary sterigmata 15 to 20m by 6 to 8m, secondary 8 to 14m by 2.5 to 

 4m; conidia globose, hyaline, 2.5 to 5.4m, smooth, with connectives. In the event that 

 continued study of these white forms reveals the existence in nature of strains with 

 more or less roughened conidiophores and conidial heads ranging to yellows, recogni- 

 tion of A. okazakii as a separate species would be warranted. Based upon current 

 information, however, we believe it preferable to consider it synonymous with A. 

 candidus Link. 



A. sachari of Chaudhuri and Sachar (Ann. Mycol. 32: 95. 1934) is more or less 

 arbitrarily left where the authors put it — as one of the A. sulphureus series near A. 

 quercinus in the A. ochraceus group. The heads are pale yellow, the sclerotia are 

 near the colors of that group, but the conidiophore is described as colorless and 

 smooth which would put it in A. candidus. 



A. sterigmatophorus Saccardo, in Mycologicae Venetae Specimen. Atti d. Soc. 

 Ven. Trent, d. Sci. Nat. 2, fasc. 2: 232. Tab. XVII, fig. 5-8. 1873; Syn. S. italica 

 Sacc. in F. italici no. 109, 1881 ; changed to S. italica Sacc. as a note only in Michelia 

 1:91. 1877; Latin diagnosis of S. italica in Saccardo Sylloge 4: 72. 1886. Described 

 from decaying corn kernels (Zea mays): white, sparse, with conidiophores un- 

 branched, 2 to 3 septate above; with vesicles globose; sterigmata described as dicho- 

 tomously or trichotomously branched with ultimate cells bearing conidial chains;
