HAPLOGRAPHIUM 



Haplographiuni Berkeley & Broome, Ann. Mag. Nat. Hist. Ill, 3 : 360, 1859. 



The type species is Haplograpliium deUcatum Berkeley & Broome. 



Hypliae repent, often not seen ; conidiophores erect, not branched, septate, 

 brown, branching at the tip, each branch bearing a chain of spores, spherical 

 or ellipsoid, green, brown, or almost hyaline, unicellular. 



This seems to be a black analogue of Penicillium, but it has not been 

 sufficiently investigated in the saprophytic species to know whether the termi- 

 nal branches are metulae and phialides or not (Fig. 135). Apparently these 

 are in the pathogenic species.

given by deBella and Marengo, in Giorn. Ital. Mai. Ven. Pelle 63: 690-697, 

 1922.] 



Isolated from a gummatous cutaneous lesion on the jaw. Pathogenic to 

 guinea pig and rabbit. 



Mycelium septate, abundantly branched, at first hyaline, then brown. 

 Sterile hyphae repent, branched, hyaline, then brown, SAfi in diameter ; conidio- 

 phores repent or erect, simple septate, black, 50-80/1. long, little or much 

 branched above, phialides 10-12/x long, ending in chains. Gonidia spherical 

 or ovoid, black, smooth, 4-5/* in diameter, ends pointed. 



Colony hemispheric, dirty white, then pea green with lanuginous center, 

 then very dark grayish green. After 30 days, colony black, dry, rugose; 

 reverse dirty white and then black. On glucose agar, colony black, zonate, 

 orbiculate.
