XII. — A Monograph of the Genus Lycoperdon (Tournef.) Fr. 



By G. Masses, F.E.M.S. 



(Bead hth June, 1887.) 



Plates XII. and XIII. 



The earliest systematic account of the genus Lyeoperdon is contained in 

 Fries' ' Systema Mycologicum,' published in 1829, where nine species are 

 described, including L. BrasUiense Fr., the only extra-European species 

 then known. Afterwards (1841) Vittadini published his ' Monographia 

 Lycoperdineorum,' in which sixteen species, all European, are described. 

 Of these, two have been removed to the allied genus Bovista. During 

 the past forty years, botanical research in every quarter of the globe has 

 added over one hundred additional species, the Eev. M. J. Berkeley alone,
