GLIOCLADIUM, PAECILOMYCES, AND SCOPULARIOPSIS 677 



(2) Gliocladium cateiiulatum series. A predominantly floecose series 

 in which the colonies show abundant radiating floecose or funiculose 

 aerial hyphae and produce abundant green masses of conidial structures 

 distributed in characteristic manner. The series is typified by G. catenu- 

 latum Oilman and Abbott, in which the conidia may either remain in 

 chains which adhere into wet columns or form slime balls wholly typical 

 of the genus. 



(3) Gliocladium deliquescens series. A dark green to fuscous series, 

 represented by such forms as G. deliquescens Sopp which is common in 

 soil, and which develops a widely spreading, submerged mycelium on 

 Czapek agar with scattered areas or clumps of conidial structures above 

 the surface. The conidia of these forms regularl}'^ collect into conspicu- 

 ous slime balls. 



The more common and easily recognized members of the genus Glio- 

 cladium may be separated as shown in a simple key, as follows : 



Page 

 I. Conidial areas colorless, cream-colored or in salmon to rosy pink shades. 



G. roseum series 677 



A. Conidia colorless, cream, or pale pink in color, wholly or in part collect- 



ing into slime balls G. roseum (Link) Bainier 678 



B. Conidia in rosy pink to vinaceous pink shades, usually remaining adherent 



in chains G. vermoeseni (Biourge) Thom 680 



II. Conidial areas in pale yellow-green to dark green shades. 



A. Conidia typically in pale yellow-green shades, commonly remaining in 



chains to form wet columns G. catenulatum series 682 



G. catenulatum Oilman and Abbott 682 



B. Conidia typically in dark green to almost black shades, always collecting 



into slime balls G. deliquescens series 686 



G. deliquescens Sopp 686 



Gliocladium roseum Series 



Tjrpe Species: Gliocladium penicilloides Corda, in Icones Fungorum IV: 



31, Taf. VII, figs. 88 and 89. 1840. 



Corda described mold colonies found fruiting upon the hymenial surface 

 of rotting Thelephora ^^^th the follo\ving characters: Colonies small, whits; 

 conidiophores erect, flexuous, enlarging above, septate, pulverulent, color- 

 less; penicillus with primary branching opposite, branchlets verticillate in 

 fours, appressed; heads of conidia globose, white; conidia 6,Lt in long axis, 

 oblong, embedded in a mucilaginous mass. 



By this description, as pointed out by Oilman and Abbott (1927), the 

 type of the genus falls in the non-green section — with the type species, 

 Gliocladium penicilloides, designated white by Corda. As seen in cultures, 

 many gradations from white to rosy, pink, or salmon shades can be found.
