North American Fungi. 171 



Growing on the ground in woods. Pennsylvania, Schweinitz, 

 Ellis; Maryland, James; S. Carolina, Atkinson; Mississippi, 

 Tracy; Ohio, Morgan; Missouri, Trelease ; Iowa, Mc Bride. Per- 

 idium commonly 3-6 inches in diameter and 4-5 inches in height, 

 but much larger specimens are sometimes met with. This species 

 abounds in the woods of Southern Ohio, growing in great patches 

 of numerous individuals. It was first described by Schweinitz 

 under the name Bovista craniiformis, N. A. Fungi No. 2256. 

 Lycoperdon delicatum, B. &: C.=Z. Ba'keleyi, Massee, and L. Mis- 

 souriense, Trelease, are more recent names for this species. I am 

 indebted to Mr. J. B. Ellis for specimens from Pennsylvania and 

 for the identification of them with the original specimens in the 

 herbarium of Schweinitz. I do not know that the edible qualities 

 of this species have been tested. 



9. C. rubro-flava, Cragin. Peridium obconic, tapering gradu- 

 ally downward to the rooting mycelium. Cortex a very thin fur- 

 fur aceous or granulose coat, with a few short, scattered spinules 

 above; inner peridium thin and fragile, at first whitish, soon 

 becoming orange-red to orange-brown in color, after maturity the 

 upper part breaking up into fragments and falling away. Subgleba 

 occupying about a third part of the peridium ; miss of spores andl 

 capillitium reddish-ochre then olivaceous-orange ; the threads very 

 long, rather thicker than the spores, branched ; spores globose, 

 even, 3-3.5 mic. in diameter, sometimes with a minute pedicel. 



Growing on the ground. Kansas, Cragin, Kellerma?i. Peridium 

 l / / 2~3 inches in height with a breadth of 1-2 inches. The pecu- 

 liar orange or rather reddish-ochre color with which the whole 

 plant is pervaded at maturity is very remarkable. 



§3. Stipitat^. Peridium depressed-globose above, abruptly 

 contracted below into a long stem-like base; subgleba not defi- 

 nitely limited above, continuous with the capillitium, persistent. 



10. C. saccata, Vahl. Peridium depressed-globose above, 

 plicate below and abruptly contracted into a long stem-like base ; 

 the base thick and stout, often lacunose, nearly equal, rarely 

 tapering downward; mycelium fibrous and filamentous. Cortex 

 a very thin coat of minute persistent spinules or granules ; inner 

 peridium white or gray becoming brownish, very thin and fragile, 

 after maturity the upper part soon breaking up into fragments and 

 falling away. Subgleba occupying the stem-like base, persistent ; 

 mass of spores and capillitium brownish-olivaceous ; the threads
