tufts of white mycelium appeared on some of the stems. By 
December 22 the growth had spread so as to form colonies 
about 2—3™" in diameter. Very little mycelium could be seen, 
but one pink mass of conidia was borne on the upper portion of 
one of the stems. On examination the mass was found to be 
composed of closely packed basidia, bearing at the end elliptical 
or oval conidia 6-7 in length, although occasionally one was 
found measuring 12 or r4u. These were sometimes united by 
short.germ tubes. Dilution cultures were made in potato-agat 
from this colony. Growth took place very slowly; some of the 
conidia gave rise to two or three germ tubes, these branched 
frequently and became closely septate. The resulting colonies 
did not advance beyond a diameter of 3~4™™, At first they 
presented a stellate, or snowflake appearance, but later became 
quite dense and compact, with a close even marginal growth. 
The mycelium assumed a deep red color, darker at the center 
and shaded to a light pirk toward the margin, and: presented a 
glazed, shining appearance. The production of conidia was not 
observed. Subsequent transfers to tube cultures on bean stems, 
as well as on sterilized raspberry stems, resulted in a very slight 
mycelial growth in scattered tufts. Some of these tufts floated 
freely on the surface of the infusion, in small stellate colonies; 
and often became attached to the sides of the tubes. In cof- 
nection with the mycelial growth were small, pink, elevated 
masses. 
So peculiar was the growth and unlike that of any other 
Species of anthracnose studied, that in order to satisfy myself 
that the growth was that of the anthracnose, fresh material was 
again obtained the following July: The growth in agar and om 
bean stems manifested the same peculiarities as before, but upon 
closer examination of the newly formed patches on the stems 
the conidia were found. These quickly fall away and form the 
small colonies which were before mentioned floating freely on a 
the infusion. The colonies in agar did not attain a diametet ©
