GENERIC DIAGNOSIS AND SYNONYMY 19 



Corda's figure and description have been interpreted as covering certain 

 fruiting forms occasionally encountered. We have had several cultures 

 showing a penicillus-like structure in which the column of conidia assumed 

 the appearance indicated by Corda's figures, but the branching system 

 lacked the definite verticils of 4 sterigmata at each node prescribed by 

 Corda. The}^ did, however, reproduce the figure of Penicillium roseum 

 as given by Thom, 1910, Avhich were subsequently recognized as repre- 

 senting a Gliocladium (Thom, 1930). In fact, many observations suggest 

 that the rosy or salmon forms which may show a penicillate condition at 

 one stage, a Gliocladium-like fruit at another, and again Clonostachys 

 heads upon the same mycelium, should be restudied and some usage de- 

 vised which will indicate the real relationships involved. Other names 

 should be reduced to proper synonymy. 



Coremium Link, in "Observationes," p. 19. 1809. 



Link described Coremium glaucum on p. 19 after describing Penicillium 

 expansum on p. 17 of his "Observationes." Comparative study of de- 

 caying fruit has led us to believe that C. glaucum was the coarsely core- 

 miform development that we now know to occur from the growth of P. 

 expansum upon such fruits as apples in storage. The name has continued 

 to be loosely applied by some to coremiform fruiting masses wherever 

 found. The generic name Coremium is, therefore, commonly listed among 

 the Stilbaceae. We can see no purpose in using the name for any lvno\vn 

 Penicillium-like organisms. 



Corollium Sopp, in Monogr., pp. 98-103, fig. 108. 1912. See also Olav 

 Johan-Olsen (Sopp) in Pharmacia, No. 22 and 23. 1904. 



Probable synonym: Paecilomyces Bainier, in Bui. Soc. Myc. France 23: 



26-27, PL VII. 1907. 



Sopp's generic description can scarcely be separated from that of his 

 t^'pe species, Corollium dermatophagum.. Corollium is reported to be 

 most nearly related to Acaulium but to connect with the true Penicillia 

 through Penicillium olivaceum and P. italicum. It appears upon moist 

 leather as a clear brown to yellow-green, close felted mycelium becoming 

 powdery or mealy in age, with conidial masses of the penicillate type borne 

 at the apices of fertile hyphae, but accompanied by abundant verticils of 

 sterigmata broadly and irregularly distributed on the fertile hyphae. 

 The type species of this genus was found upon a pair of old boots in a 

 military depot in Norway. It grows readily upon a wide range of media 

 and is thermophilic.
