Four examples of this species sent by Vittadini to the Rev. 
M. J. Berkeley are now in the Berkeley collection of fungi in 
the Kew Herbarium. Liable to be confounded with G. 
Michelianus , from which the present species differs in the 
sessile endoperidium, and the presence of a silky zone sur- 
rounding the peristome. 
Geaster Michelianus, W. G. Smith (Fig. 27). Exoperidium

coming dry and crumbling away ; endoperidium subsessile, 
peristome piano-conic, ciliato-fimbriate, pale ; columella large,
