312 A MANUAL OF THE PENICILLIA 



discussion (5f Biourge's treatment (1923) of P. sulfureum Sopp. It is our 

 belief that Zaleski's P. miczijnshii and Biourge's conception of Sopp's 

 species were based upon essentially similar molds. Sopp's P. sulfureum 

 is believed to have represented a form approximating P. purpurogenum 

 Stoll. 



Another culture, NRRL 2134, received from the Centraalbureau in 

 June 1946, as PenicilUum mangini Duche and Heim, duplicates almost 

 exactly that received from them in July as P. sulfureum Sopp. This 

 culture was received originally from Duche in 1931 and presumably repre- 

 sented their type. The culture received by us was submitted to Duche 

 when he visited our Laboratory in December 1946, but he failed to verify 

 it as satisfactorily representing his species, maintaining that the culture 

 studied and described by them produced larger sclerotia predominantly 

 in light brown shades. 



The presence of aggregates of inflated, heav>'-walled cells in strains 

 which otherwise closely approximate PenicilUum miczynskii, is believed to 

 indicate a relationship of this species to P. soppi in the P. raistrickii series. 

 PenicilUum, miczynskii is accordingly keyed in that portion of the Di- 

 varicata also.

Colonies on Czapek's solution agar growing rather restrictedly, attain- 

 ing a diameter of 2.5 to 3.0 cm. in 2 to 3 weeks at room temperature, con- 

 sisting of a fairly thin tough felt, strongly folded and wrinkled, irregularly 

 in central area and more or less radially toward the colony margin (fig. 

 83C), predominantly white but in some cultures developing abundant 

 conidial structures in marginal areas, in light blue-green shades near ce- 

 landine to artemisia green (Ridgway, PL XLVII), in other cultures appear- 

 ing "wet", definitely funiculose and producing few conidia; odor indefinite 

 or lacking; exudate limited in amount, colorless; reverse colorless to faint 

 yellowish; penicilli varying greatly in size and pattern but typically di- 

 varicate; conidiophores variable in size and origin, from 50 to 300/i in 

 length by 1.5 to 2.2^ in diameter, arising either directly from the substra- 

 tum or as branches from aerial hyphae, with walls smooth; penicilli con- 

 sisting of single verticils of sterigmata or irregular verticils of 2 to several 

 divergent unequal branches (metulae) about 10 to 15m in length, some 

 shorter about 7 or 8m, bearing strongly divergent sterigmata and conidial 

 chains; sterigmata mostly in clusters of 5 to 7, occasionally up to 10, 

 typically 6 to 7m by 2.0 to 2.2m but very commonly swollen and up to 4.0
