THE FUNGI IMPERFECTI AND THE ASCOMYCETES 



which P. janthellinum is typical, belongs here. The soil species show 

 yellow to red colors in the mycelium ; the spores are green. 



Funiculosa. Trailing ropes or bundles of hyphae are found at the 

 edge of the growing colony. 



Fasciculata. Species forming coremia, or tending to form coremia, 

 are grouped together in this section. P. expansum and P. italicum 

 are important.

Fig. 55. Paecilomyces. 

 Single sterigmata (a) bend 

 (b) away from the main 

 axis. Sterigmata (c) are 

 elongated. Conidia (d) 

 are oval. Many conidio- 

 phores resemble those of 

 Penicillium. From Conant 

 et al, Manual of Clinical 

 Mycology, 1944. 



Although species of Penicillium have been found from time to time 

 in various pathological lesions of man, it is doubtful that any of 

 them is truly pathogenic. 



Gliocladium. Members of this genus form branched spore heads 

 resembling those of Penicillium, but the conidia become surrounded 

 by a mass of slime which bind together all the spores of one spore 

 head into a rounded mass. But the conidia, in some species at least, 

 are formed in chains, as in Penicillium. 



Paecilomyces. Paecilomyces is differentiated from Penicillium 

 by its longer tubular sterigmata, the tubular processes being bent 

 away from the axis of the sterigma, and by greater irregularity of 

 the branching, which is only in part verticillate. The perfect stage 

 of this fungus has been found at least once.^- Spicaria is a generic 

 name sometimes used instead of Paecilomyces.
