M. ERUMPENS E. & E., Proc. Phila. Acad., 1894, 386. Type habitat : On dead limbs of Tsuga Canadensis, March, 1895 (Nuttall, discov. 1398, 371). Sporodochia scattered, depressed-globose, .5 mm. diam eter, at first covered by the epidermis, raising it into little whitish pustules, then erumpent and closely embraced by the ruptured epidermis, at first orange-red, then becoming nearly black, and finally leaving subcupuliform cavities in the bark, when dry. Conidia falcate to fusiform, multinu cleate, and finally three or more septate, 60 to 83 x 3 to 4.5 ц hyaline, narrowing to a slender point at each end, borne on short sporophores (20 to 35 ц), which are more or less branched above. Differs from M. coccophila Desm. in the shape of the sporodochia and their subcuticular origin. (The additional description, incorporated in this relation of the specific characters, is by E. & E.)
