the measurement of the spores of E. Vaccinii is given as 5-8p. 
On turning to Woronin’s paper,” to which both of these de 
scriptions are referred, it is seen that the measurement given 
by him is 14-17 x 3y. 
Besides the basidiospores there are found certain forms of 
conidial fructification. The first form is like that described 
by other writers on Exobasidium Vaccinii and consists of 
small acicular spores borne on much branched hyphz among 
the basidia. The conidia of the second form are larger and are 
borne singly on rather stout hyphe not occurring with the 
basidia (fig. 11). In germinating both of these forms send 
out the small acicular secondary spores, like those produced 
in the germination of the basidiospores. The large hollow 
distortions are also found on other species of Andromeda. 
Specimens of an Exobasidium on Andromeda floribunda wert 
sent me by Dr. W. C. Sturgis, collected by him in West Vir- 
cine. which resembles exactly in all respects the E. Androm- 
ede. 
these distortions resembles Woronin’s figures.? There is 
not a very great derangement of the leaf tissues; the palisade 
cells are somewhat enlarged and the parenchyma consider 
ably thicker than is normal. The hyphz and basidia are in
