long, browa. Brauches issuing from tlie middle portion of the 

 hyphffi, spreading, simple or 2-o-parted, hyaline at first, becoming 

 brown, 15-30 x 22//, faintly septate, bearing at their tips the cylin- 

 drical, hyaline, straight; obtuse, 3-4-nucleate, 8-10 x l2-2;/. conidia. 



The effused hyph?e appear like a thin, pale rose-colored pubes- 

 cence on the bark. 



Closely allied to C. stachyobola Sacc, but the color is different, the 

 branches often divided and the hyphse not perceptibly swollen at the 

 base. 



Stachylidium carioinum E. & E. 



On dead leaves of Carex Fraseri, Nuttallburg, West Va., Feb. 

 1894 (L. W. Nuttall, No. 335). 



Hyphse fasciculate, brown, septate, 600-700 x Si/s simple or 

 occasionally forked above, towards the top, with short-cylindrical, 

 hyaline branches opposite or in whorls of thi-ee, beai-ing at their tips 

 the elliptical, hyaline, 4-5 x 12-2// conidia, collected into a globose 

 head 10-12// diam. 



Coniosporium microsporum E. & E., n. sp. 



On dead herbaceous stems (Senecio triangularis), Medicine Bow 

 Kange, Colo., July, 1894 (Prof C. S. Crandall, No. 23). 



Acervuli at first covered by the thin epidermis, soon erurapent, 1- 

 3 mm. diam., black, consisting of a mass of minute (3//), globose, 

 olive- brown, conidia. 



Torula (Tracliytora) sporodesmoides E. & E. 



On bark of dead limbs, Pasadena, Cala. , Jan. 1894 (Prof A. J. 

 McClatchie, No. 622). 



Pulvinate or subeffused, pulvinuli, hemispherical, sooty black, i- 

 f mm. diam. Creeping mycelium scanty, hyaline at first, sending 

 up short, fertile branches, from which the concatenate conidia are 

 formed by constriction. Conidia elliptical, 8-10 x 5-6/-, nniseptate 

 but not constricted, yellowish-brown at first, becoming nearly opake 

 and distinctly roughened. Often where 2 or more threads lie in con- 

 tact, the cells of the different threads become laterally connate, form- 

 ing irregularly shaped aggregations of conidia resembling Sporodes- 

 miiim. 



This differs from T. dimidiata Penz. in the nniseptate, rough 

 conidia.
