INTRODUCTION TO CRYPTOGAMIC BOTANY. 



there are distinct gUls, as decided as those of Xerotus. The 

 genus is, in fact, scarcely distinguishable from a true Hymeno- 

 mycete. The spores exhibit few pecuharities ; and where they 

 have been observed in situ, they are borne by short spicules 

 upon the sporophores. The flocci of Podaxon (Fig. 5, c) ex-

on the Swan Eiver, is said to be one of the most delicious of 

 esculent Fungi. A species of Podaxon has been used to cure 

 ulcers. Podaxon affects mostly the nests of white ants, but

 grass in Teneriffe, and Egypt. None of the species ascend 

 higher than the shores of the Mediterranean. Podaxon occurs
