FUNGI IMPERFECTI. 



Faded spots appear on the leaA'es, becoming later greyish brown dotted 

 over with minute bhick points, the couidial patches.^ 



C. ampelinum C'av. causes little dry spots on the leaves of vine, fre- 

 quently in such numbers that the whole leaf dries up. 



C. kentiae Hals, attacks palm -seed lings so 

 that tlieir leaves do not unfold. 



C. cyclameneae Hals, occurs on Cyclamen. 



Scoleco-Allantosporae. 



Cylindrospormm. 



The white and shiniiio- couidial 

 cushions are embedded in the host- 

 plants. The conidia are filamentous, 

 frequently somewhat twisted. 



Cylindrospormm Tubeufianum Alles- 

 cher. This attacks the livino- oreen fruit 

 of the bird-cherry, and causes the forma- 

 tion of brown spots from which pustules 

 break out ; the premature dropping of 

 diseased fruits follows. In the locality 

 where I observed this disease, numerous 

 trees were attacked and most of the frnit 

 on each was badly diseased. The my- 

 celium spreads through epicarp and 

 mesocarp, but does not penetrate into 

 the endocarp, so that the development 

 of the embryo is not directly interfered 

 with. The conidia originate in pycnidial 

 cavities without any- special peridium ; 

 their shape is given in the annexed 

 diagnosis.^ The pycnidial cavities arise 



under the epidermis which is afterwards ruptured and witli the 



cells underlying it becomes brown and dead.

 mention is made of it in the later paper by Webber and Swingle (" Diseases of 

 Citrous Fruits in Florida," U.S.A. Dapt. of Agriniltiire Bvilefin, 8, 1896). (Edit.)
