GLIOCLADIUM, PAECILOMYCES, AND SCOPULARIOPSIS 697 



A considerable number of new species have been described by Zach 

 (1934), van Beyma (1935, 1937, 1939), von Szilvinyi (1941), and others 

 since the pubHcation of Thorn's Monograph in 1930. It is estimated that 

 upward of 100 names for species of Scopidariopsis appear in the hterature. 

 No one has made a careful and thorough study of the group. Until some- 

 one can study in comparative culture upon various substrata all of the so- 

 called species and varieties obtainable, the taxonomy and the relationships 

 of species in the genus Scopulariopsis will remain in its present confused 



state. 



In the meantime, we believe that our wisest course is to present a fairly 

 general description covering the forms most commonly encountered which 

 are, at the same time, representative of the type species Scopulariopsis 

 hrevicaulis (Sacc.) Bainier. Following this presentation a few notations 

 will be made relative to groups of strains which we beheve to be recog- 

 nizable. In some cases these may be correlated with certain described 

 species and varieties. No attempt mil be made to give a complete and 

 critical coverage of the genus Scopulariopsis.

Colonies on Czapek's solution agar spreading rather broadly in most 

 strains (fig. 172A), more or less restricted in others, comparatively thin, 

 plane, or irregularly but not deeply furrowed, at first grayish white, then 

 avellaneous, or yellowish brown even to light chocolate, with surface char- 

 acterized by closely crowded, short conidiophores to produce powdery 

 conidial areas overgrown by loosely trailing floccose hyphae and ropes of 

 hyphae in most strains, deeper and less heavily sporing in others, with 

 margin usually indeterminate and broadly spreading, azonate or broadly 

 zonate from an uneven production of conidia. Conidiophores short, 

 mostly 10-30^, arising directly from the submerged hyphae, or irregularly 

 borne as lateral and perpendicular branches from trailing aerial hyphae 

 and ropes of hj^ihae (fig. 172B). Conichal fructifications either simple 

 and unbranched, sparingly branched, or consisting of verticillate and irregu- 

 lar branching systems bearing numerous divergent chains of conidia (fig.
