The species here represented is the one to which we misapplied 
the name pyriforme in our previous paper. In gross appearance it 
resembles somewhat the genuine pyriforme although it is usually 
on the smaller branches or stems while the latter is more often on 
larger limbs or trunks. In general appearance and in the habit 
of attacking the stems of seedlings and small trees this species is 
perhaps more closely allied to the white pine rust. It differs from 
that species very materially in microscopic spore characters, hav- 
ing larger, thicker-walled spores, which are verrucose with coarse, 
irregular, deciduous tubercles, rather than with uniform, perma- 
nent tubercles.
