fore him when he described the genus. His fig. 1 no doubt portrays 

 the third species in our present list. More recent writers, from Persoon 

 down, have used Micheli's designation, but differed in regard to the 

 limits to which the name should be applied. It is here used substan- 

 tially as in 1729. Fries and after him Rostafinski make a mistake 

 in quoting Retzius as writing Lycogala. Retzius wrote Lycoperdon 

 sessile (Kongl. Vetenskaps Acad. Handling, for Ar 1769, 254).

^Ethalia solitary or clustered, depressed-spherical, or, when crowded, 

 irregular, olivaceous or blackish, minutely warted, 3-10 mm. in di- 

 ameter, dehiscing irregularly, but more often near the apex; peridium

 flattened tubules extended inwardly among the spores, everywhere 

 marked by transverse wrinkles, ridges, and warts, the free ends of the 

 ultimate branchlets rounded, concolorous with the spores; spore-mass,
