BURT—THELEPHORACEAE OF NORTH AMERICA. VIII 239 
The collections which have been available seem to indicate 
that Соторһоға is more abundant in temperate than in trop- 
ical regions. 
Our few species which have cystidia are not segregated 
as Coniophorella, because such segregation would place two 
common species, C. suffocata and C. olivascens, in the posi- 
tion of troublesome intermediates with some of their speci- 
mens seeming to belong in Coniophora in the restricted sense 
and others in Comophorella. The per cent of connecting 
species is obviously too large for cleavage into natural genera. 
KEY ro THE SPECIES 
E эне incrusted nor hair-like cystidia present in the hymenium, with

distingalaheble from the basidia, and of С. olivascens, some sections of
