but merely an abuormal or imdeveioped state of some higher fungus. 

 Compare Coccospom, Wallr. 



Glceosporium SEPTOiiioiDss, Sacc {Marsonia quercina, Winter. 

 Hedw. 1884, p. 171.) 



Spots determinate, round or irregular, 2 — i mm., occasionally con- 

 fluent, yellowish brown, with a dark margin. Acervuli generally solitary 

 in the center of the spots, sometimes 2 — 4 on a spot, covered, slightly 

 elevated, finally collapsing. Spores fusoid, more or less curved, acute at 

 each end, hyaline, nucl^olate, endochrome at length indistinctly parted 

 in the middle, 15—24 x i— 2 



On leaves of Quercus imbricaria, Missouri (Demetrio.) On leaves of 

 Q, coccinea, Newfleld, i^. J. This should be placed in Marsonia, if 

 that genus is to be retained as distinct from Gloeosporium, for the 

 mature spores have the endochrome more or less distinctly di^dded 

 in the middle, often as distinctly so as in 3L Martini, S. &E., from 

 which this differs in its loi;ger and narrower spores. The appearance of 

 the collapsed acervuli and of the spots is almost exactly the same as that 

 of Cryptosvoriiim epiphi/llum, C. & E., which is also a closely allied pro- 

 duction. 



BoTKYTis PATULA, Sacc. & Berlese. 



Tufts minute, whitish becoming yellowish, cottony, suborbicular, 

 fertile hyphge ascending, continuous, filiform, subhyaUne, sending out 

 branches and branchiets nearly at a right angle and forming an imperfect 

 panicle. Conidia large, globose-ellipsoid, 30 fJ-. hyaline or yellowish. 



On dead branches of Bubus strigosus, Newfield, N. J. 



BoTRYTis ciNER^LLA. Sacc. & Winter. 



Tufts pulvinulate, suborbicular, U mm. diameter or confluent- 

 effused, velutinous, cinereous. Ilyphse fasciculate, ascending, septulate, 

 pale brown below, 2—3 times alternately or oppositely branched, branches 

 acute at the tips. Conidia globose, minute, 4—5 /-'-, subhyaline, terminal. 



On bark of Carya aVoa, Missouri, C. H. Demetrio. 



Cercospora PULViNULATA, Sacc. & Winter. 



Spots amphigenous, suborbicular, ruf of errugineous. Tufts hypophyl- 

 lous, punctiform arising from a hemispheric, dark-olive cellular base. 

 Hyphse short, continuous, subdenticulate, simple, pale olive. -Conidia 

 bacillary, subobtuse, obsoletely 3-septate, 40—50 x 3^ /^-, pale olive. 



On fading leaves of Morus rubra, Missouri (Demetrio). The specific 

 name is badly chosen, differing so little from 0. pulvinula, C. & E. 



The following species was overlooked in the Enumeration of Cerco- 

 s poise. 



Cercospora glomerata, Hark. Bull. Cal. Acad., Feb. 1885, p. 164. 



Hyphse short, springing from a tubercular, stroma-like base. Coni- 

 dia brown, slightly attenuated upwards. 3— 5-septate, 60— 70x 10—12 



On living leaves of Garrya elliptica, Tamalpais, Cal., March, 1884 

 (Harkness.) The parts of the leaf occupied by the fungus soon assume 

 a dry, dead look.
