REPORT OF THE BoTANIST. 75 
separated localities is an interesting and remarkable feature in 
these singular plants. 
POLYPORUS NIGROPURPURASCENS Schw. 
A resupinate form was found on elm in Bethlehem. In some 
of these specimens the hymenium was much paler than is usual 
in this species. The pores are seated on a thin but tough elas- 
tic membrane which is separable from the substance of the 
pileus. 
STEREUM BALSAMEUM PA. 
The hymenium in this becomes red or blood-stained where 
wounded as in S. sanguinolentum. Its general color is darker 
than in that species. 
STEREUM PURPUREUM FY. 
I find this a very variable plant. One form has the hymenium 
very pale with only a slight purplish tint. Another has the 
pileus zoneless and when moist it is darker than when dry. 
CoRYNEUM CLAV =sPoruM Ph. 
This proves to be the same as Hzosporium Tilie Lk. Ihave 
never been able to find it with flocci and therefore doubt if it 
should be referred to the genus Helminthosporium as some 
authors think. 
Pucorn1aA HrERAct Mart. 
Mr. M. Ruger sends specimens of a Puccinia found on leaves 
of hawkweed, at Woodhaven, L. L., which should perhaps be 
referred to this species, but I fail to find any good mark of 
distinction between it and P. variabilis. 
PucctntA AMPHIBII A'ch. 
This is now regarded as distinct from P. Polygonorum, and 
our specimens of Puccinia on leaves of P. amphibium should 
be referred to.it. 
USTILAGO URCEOLORUM 7727. 
This occurs in the Adirondack region on Carea stricta, C. 
stellulata, C. crinita, C. utriculata and C. oligosperma. 
TRICHOBASIS Hower Ph. 
I would change this name to Uromyces Howei Pk. since I 
find that the pedicels, though very short and obscure, are 
permanent.
