摘要:

SummaryThis account presents photomicrographs depicting the appearance of the anthracnose organism of snowberry,Sphaceloma Symphoricarpi, as represented by sections of snowberry leaves gathered at Grantsville, Maryland, August, 1928. The sectioning was not done until several months later, the leaves in the meantime having been dried and preserved as herbarium specimens. Several hours previous to sectioning the leaves were placed in a moist atmosphere. At the time of sectioning theSphacelomamay have been still viable, as was definitely noted by Scribner for specimens of the raspberrySphacelomaof similar age. Not all of the characteristics of the organism depicted have been reported hitherto, but essentially all of them had been observed and discussed in one way or another for closely related species.
