The same name had also been used by Passerini in his " Erb. 
Critt. Ital." issued in 1873, and Cooke regards this fungus as 
identical with the one named by him. However, Passerini* sub- 
sequently in 1887, on further consideration, pronounced this to 
be the stilbospore condition of Puccinia pruni, Pers. This name 
of Uromyces amygdali is now being used in the different Colonies, 
having such a high authority at the back of it, but as we shall 
presently see, it is a misnomer, or rather a synonym of Puccinia 
pruni, Pers., as already decided by Passerini. 
Puccinia pruni-spinosce was tirst employed by Persoon in his 
" Synopsis Methodica Fungorum," published in 1797, the specific 
name being derived from the host-plant, Prunus spiuosa or black- 
thorn, but as the fungus is now known to have different hosts 
belonging to the genus Prunus, the spinoscv is dropped as a matter 
of convenience. 
Next, Link in his " Species Fungorum," published in 1825, 
named the same fungus Puccinia prunorum. Uromyces prunorum, 
Lk., var. amygdali, Yize, was applied by J. E. Yizef to a Calif or- 
nian specimen on peach leaves in 1878, and the same name was 
used by the Rev. C. Kalchbrenner| for a fungus on peach leaves 
from Caffraria in 1882. Next, in 1883, Dr. Cooke§ recorded 
Puccinia prunorum, Lk., for Victoria, then in 1886 Uromyces 
amygdali, Cooke, for Queensland, and finally in his " Handbook 
of Australian Fungi " for Queensland, Victoria and New South 
Wales on peaeh and almond leaves in 1892. It was suggested 
in Tryon's " Report on Insect and Fungus Pests "|| that this 
fungus belonged to Puccinia pruni, but Dr. Cooke repudiates the 
suggestion in the " Handbook," and with dogged determination 
sticks to his point in the following note : " We decline to accept 
this as agreeing with any form of Puccinia pruni with which it 
is commonly associated."
