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 Fuccinia 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 Fuccinia 

 pruni, Pers., as already decided by Passerini. 



Fuccinia pruni-spinosce was tirst employed by Persoon in his 

 *' Synopsis Methodica Fungorum," published in 1797, the specific 

 name being derived from the host-plant, Frunus spinosa or black- 

 thorn, but as the fungus is now known to have different hosts 

 belonging to the genus Prunus, the spinoscn is dropped as a matter 

 of convenience. 



Next, Link in his " Species Fungorum,'"' published in 1825, 

 named the same fungus Fuccinia primorum. Uromyces prunoriim, 

 Lk., var. amygdali, Yize, was applied by J. E. Yizet 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 

 Faccinia prunoram, Lk., for Victoria, then in 1886 Uromyces 

 amygdali, Cooke, for Queensland, and finally in his " Handljook 

 of Australian Fungi " for Queensland, Victoria and New South 

 Wales on peach and almond leaves in 1892. It was suggested 

 in Tryon's " Report on Insect and Fungus Pests "|| that this 

 fungus belonged to Fuccinia 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 oi'^Faccinia pruni with which it 

 is commonly associated."
