20 A MANUAL OF THE PENICILLIA 



Dadylormjces SoipTp, in Monogr., pp. 33, 35-42, fig. 20; Taf. IV, figs. 21-30. 

 1912. Type species: D. ihermopMlus Sopp. 



Probable synonym: Thermoascus Miehe (1907). 



Sopp's diagnosis hinged on the follomng items: Conidiophores bear 

 finger-Hke branches at the apex, each enlarging to a vesicle-like apex, 

 suggestive of the basidia of Tomentella, these branches produce similar 

 secondary verticils and such branching may be repeated three, four, or 

 more times, hence the name Dactylomyces, perithecium formation begins 

 quicldy and the cycle from ascospore to ascospore requires only a few 

 days. Aside from the general resemblance of the perithecium to that of 

 certain Penicillia and the rough similarities of the conidial apparatus, 

 the true affinities of the organism studied by Sopp are difficult to deter- 

 mine. 



Professor Ralph Emerson, studying the retting of guayule shrub at 

 Salinas, California reisolated a strain beheved to represent Sopp's species 

 and sent it to us. Conidial structures are very large and coarse, evanes- 

 cent, but somewhat penicillate. Perithecia are strongly suggestive of 

 those seen in Penicillium vermiculatum and P. wortmanni but larger; 

 ascospores are quite large, elliptical, echinulate. The species is thermo- 

 philic. 



Eidamia, in Home and Williamson, Ann. Bot. 37; 393^32, figs. 1-13. 



1923 



These authors assigned two new species to Lindau's genus Eidamia. 

 One of these, when examined, proved to be a common Trichoderma and 

 the other some strain of Paecilomyces. Assignment to Eidamia, unjusti- 

 fied in either case, was in the latter instance based largely upon the pro- 

 duction of enlarged, more or less heavy-walled "macrospores" which were 

 either terminal or intercallary. 



Ewpenicillium Ludwig, in Lehrb. niederen ICrypt., pp. 263-265. 1892. 



Stuttgart. 



Ludwig merely accepted Bref eld's discussion of Penicillium glaucum 

 and made it the basis of a new ascomycetous genus, Eupenicillium. His 

 discussion was headed, "Der gemeine Pinselschimmel, 'Eupenicillium 

 crustaceum (L.) Fr. (P. glaucumy", and consisted of an abstract of Bre- 

 feld's discussion of P. glaucum with the generic name changed to Eupeni- 

 cillium. Ludwig offered no real contribution to our knowledge of the 

 genus and his proposals have been justly ignored by most workers.
