700 A MANUAL OF THE PENICILLIA 



We have made a limited examination of all strains available from our 

 Collection, and also of many strains representing "species" received from 

 the Centraalbureau in 1946. We hesitate to attempt any separation of 

 species until the whole group can be thoroughly restudied. Nevertheless, 

 with the view that our observations may be of some value to the user of 

 this Manual, we are hsting below certain patterns of growth and mor- 

 phology represented by the strains in our possession. Named cultures are 

 cited as they are represented in the different groupings. 



Group I: Represented by the species Scopidariopsis hrevicaulis (Sacc.) 

 Bain, in its typical aspect as described above. Contained herein are numer- 

 ous strains maintained in our Collection and two received from Baarn under 

 this name. Cultures in our possession, designated S. hrevicaulis var. 

 hominis Brumpt and Langeron (in Brumpt, 1913) differ from the species, 

 if at all, only in producing conidia of slightly darker color with walls gener- 

 ally more conspicuously roughened. 



Group II: Colonies differing from the above in showing increased ropi- 

 ness and Ughter colors in white to light beige shades, and conidia irregularly 

 roughened with many cells appearing smooth. Growth on malt agar is 

 very slow or lacldng. Represented by two strains received from Baarn 

 as Scopulariopsis hrevicaulis var. alba Thom, and two strains received as 

 S. insectivora (Olsen-Sopp) Biourge. A tliird strain received under the 

 latter name represents a typical strain of S. hrevicaulis. 



Group III: Colonies similar to Group I in general texture and pattern 

 and consistently hght colored as in Group II, but showing conidia con- 

 sistently smooth-walled. Growth on malt agar is restricted, usually non- 

 sporulating. Represented by cultures in our Collection, and by strains 

 received from Baarn as Scopulariopsis hrevicaulis var. glahra Thom, and 

 others from Baarn as S. candelahrum Loub., S. hrumptii Salvanet-Duval, 

 and *S. hestae (Poll.) Nann. 



Growp IV: Colonies hke the preceding in texture and appearance, with 

 conidia similarly smooth-walled; producing cellular bodies ranging from 

 white to blacldsh which we presume to be abortive perithecia (no asco- 

 spores have been seen). Represented by two strains from Baarn as S. alho- 

 flavescens Zach. This species was described originally as ascosporic, with 

 small black perithecia. 



Group V: Colonies conspicuously furrowed, dark dull broAvn in color; 

 conidia heavy-walled but consistently smooth. Colonies growing very 

 restrictedly on malt agar. Represented by strains received from Baarn as 

 Scopulariopsis arnoldi Mang. and Pat., and S. fusca Zach. 



Group VI: Colonies deeper, with margins tending to be abrupt; conidial 

 areas in dull grayish to deep brown shades, conidia smooth with walls 

 thick and greenish brown in color. Growth on malt agar is restricted.
