124 A MANUAL OF THE PENICILLIA 



b. Colonies quickly developing some shade of green in conidial areas 



P. commune series 429 



3. Colonies with surface typically ropy or funiculose from aggregation 



of aerial hyphae; conidial structures arising primarily from aerial 

 hyphae or ropes of hyphae Funiculosa Sub-section 445 



a. Conidial areas in yellow-green, blue-green, or gray-green shades; 



penicilli large as in the Lanata and Fasciculata; conidia sub- 

 globose to elliptical P. terrestre series 446 



b. Conidial areas variously colored but never in green shades; peni- 



cilli often comparatively narrow; conidia strongly elliptical to 

 cyclindrical P. pallidum series 458 



4. Colonies with surface growth appearing mealy, tufted, fasciculate, or 



coremiform due to aggregation of conidiophores into upright fas- 

 cicles or bundles Fasciculata Sub-section 467 



a. Sclerotia characteristically produced P. gladioli series 471 



b. Sclerotia not produced. 



1'. Colonies with simple conidiophores and fascicles intermixed, 

 but with simple conidiophores usually predominating, 

 aa. Conidial areas not developing true green colors in areas of 



ripe conidia P. ochraceum series 475 



bb. Conidial areas typically in bright yellow-green shades, 



conidiophores rough P. viridicatum series 481 



cc. Conidial areas typically in blue-green shades with the blue 

 element predominant or at least clearly evident; conidio- 

 phores rough or smooth P. cijclopium series 490 



dd. Conidial areas typically in yellow-green or glaucous shades ; 



conidiophores rough or smooth P. expansum series 508 



ee. Conidial areas typically in pale to dull gray-green shades; 

 conidiophores smooth-walled. 

 1". Sterigmata usually 8^ or more in length 



P. italicum series 523 



2". Sterigmata 6^ or less in length P. urticae series 531 



2'. Colonies with most conidiophores aggregated into fascicles or 

 definite coremia. 

 aa. Coremia predominating but interspersed with abundant 



simple conidiophores P. granulatum series 539 



bb. Coremia very prominent, with simple conidiophores lack- 

 ing or very few in number P. clariforme series 548 



III. Penicilli characteristically biverticillate and symmetrical, but sometimes 

 fractional in some species and strains; sterigmata typically lanceolate, 

 with apices long-tapered, acuminate 



Biverticillata-Symmetbica Section 557 



A. Colonies producing perithecia or sclerotia. 



1. Colonies producing soft perithecia upon most substrata, usually 



bright yellow in color P. luteum series 564 



2. Colonies producing sclerotia or masses of thick-walled cells, com- 



monly embedded in the substratum 



P. novae -zeelandiae (and scattered strains in other conidial series) 665 



B. Colonies not producing perithecia or sclerotia. 



1. Colonies regularly developing abundant, erect coremia 



P. duclauxi series 609
