hoped to publish at an early day, as a bulletin of the Alabama 
Experiment Station. During the course of the work a number 
of species have been found that seem to be undescribed. As the 
Experiment Station Bulletins do not have a sufficiently wide cir- 
culation among botanists to justify their use as a medium for pub- 
lishing new species, I give below descriptions of some Fungi 
Imperfecti which appear to be new. Type specimens* are de- 
posited in the herbaria of the Alabama Polytechnic Institute, 
the Agricultural Department at Washington, Harvard Univer- 
sity, Columbia University and in the private herbarium of the , 
writer. A number of other seemingly new species have been de- 
tected, but publication is withheld for the present for lack of 
sufficient material, or for further study. 
COLLETOTRICHUM JUSSIAEAE N. sp. 
On orbicular, yellowish-white, arid, purple-bordered spots, 
2-10 mm. in diameter; acervuli scattered, not erumpent, small, 
about 100 p43 setae few, brown, transparent, occasionally septate, 
obtuse, mostly straight, from a somewhat enlarged base, about 
70—-100x6-8 [ss : 
On living leaves of /usstaea decurrens, Auburn, Ala., August 
27, 1891. G. F. Atkinson. 
CYLINDROSPORIUM CELTIDIS n. sp. 
Spots small, yellowish, indefinite and. indistinct ; acervuli hypo- 
phyllous, scattered, often only one on a spot, yellowish brown; 
Spores cylindric or clavate, guttate, at length obscurely several 
Septate, 20-25x3 yu. 
On living leaves of Celtis Mississippiensis, Montgomery, Ala. 
November 10, 1891. G. F. Atkinson. ‘ 
_ This somewhat closely resembles Cylindrosporium ulmicolum 
E. &. E.,on Ulmus, but the spores are only half as long. 
DIPLODIA MACROSPORA N. Sp. 
Perithecia scattered, large, carbonaceous, buried, ostiole erum- 
Pent, elevating and. rupturing the epidermis; spores very long,. 
dark fuliginous, irregularly clavate, on short slender hyaline ba- : 
*It seems useless among the fungi to attempt to distinguish between types and — 
duplicate types. The descriptions have always been drawn from an examination cf 
all the available materialand this has been divided into as many “type specimens” 
#8 the quantity justified. . ee ee
