I. — Phallogaster saccatus, Morgan, n. sp. , 



Fetid, single or caespitose, often several arising from an 

 abundant slender, white, fibrous, branching myceHum. 

 Peridium obovoid, usuallj^ tapering below, thick, tough-fleshy, 

 the surface smooth and glabrous, glaucous-pink or flesh-color; 

 rupturing b}- the gradual decay of the wall. The interior of 

 the peridium is at first filled above by the gleba, below by a 

 white floccose substance, both are transformed into mucus 

 upon the maturity of the spores. The gleba consists of 

 numerous green lobes, or masses, sometimes quite distinct 

 from each other, seated on the white glairy inner wall of the 

 peridium. Spores abundant, floating in the mucus, trans- 

 parent and colorless under the microscope, linear-oblong, 

 4-5 X 1.5 mic. 



Growing singly or in clusters of three or four attached to 

 the same stringy mycelium, which penetrates the rotten wood 

 of an old stick or trunk. Peridium 1-2 inches in height and 

 ^2-1 inch in diameter. I observed upon the fibers of the 

 mycelium abundant crystals of calcium oxalate, as figured by 

 DeBary on the mycelial strands of Phallus canimis. 



The peculiar phalloid odor is not so powerful as in other 

 members of the family.
