covered with minute teeth (Fig. 712) visible to the eye, which the 

 microscope shows aie bundles of sterile hyphae, the base of the bundles 

 imbedded in the hymenium (Fig. 713). 



This is not a rare plant in tropical America, and one of the first 

 foreign species to reach Europe, having been labeled Peziza flava-by 

 Swartz, from Jamaica, over a hundred years ago. It has been found 

 by Langlois in Southern United States, and I have recently col- 

 lected it in Florida. 



SYNONYMS. Originally named Peziza flava by Swartz, it was changed to Hydnum flavum by- 

 Berkeley, who also called a pale form of it from Brazil, Hydnum brunneoleucum.
