410 BULLETIN OF THE BUSSEY INSTITUTION, 
Of fungi occurring on olive-trees, we have an early account by 
Montagne in the Annales des Sciences Naturelles, 3 série, tome 12, 
1849, of a fungus mentioned in the “ Bull. Soc. centr. d’agric.,” 2 série, 
iv. p. 267, under the name of Antennaria elzophila, which had been 
found at Perpignan in 1829, which caused ravages somewhat the same 
as the California fungus, and which had previously been referred by 
him to Cladosporium Fumago: It was probably the same plant as the 
Torula Olez of Castagne. Tulasne, however, in the “ Carpologia 
Fungorum,” vol. ii. p. 279, showed that the Friesian genus Antennaria 
was the pycnidial state of species of fungi of which Capnodium was 
the ascigerous state. He restored the old name, Fumago, and gave a 
detailed account of Fumago salicina, which was illustrated in his un- 
rivalled manner. 
The fungus from California is evidently the same as that which has 
been known in Europe since 1829. We have examined two authen- 
tic specimens of Antennaria eleophila Mont.,—one from the Duby 
Herbarium, the other from that of De Notaris, — and the structure is 
precisely that of the pyenidial-bearing portion of the California fungus. 
The stylospore-bearing portion of our fungus is the Capnodium Citri 
of Berkeley and Desmaziéres, to which they refer the Fumago Citri 
of Persoon and Turpin. Montagne had observed only the pyenidial 
form — his Antennaria eleophila — on olives; whereas, on the orange, 
he found only the stylospore form, — his Capnodium Citri. Berkeley 
and Desmaziéres make mention only of stylospores on species of Cit- 
rus. We have been so fortunate as to find, on the specimens from 
California, both pycnidia and stylospores, and on both olives and 
oranges, — which proves the identity of Antennaria eleophila (Mont.) 
and Capnodium Citri (Berk. and Desm.). The perfect ascigerous 
state of the fungus we have not found; nor do Berkeley and Desma- 
zieres seem to have met with it, for they add to their description, 
“asci have not been observed.” We have not been able to find any 
recorded instance of asci having been found in Capnodium Citri. 
Tulasne remarks, — quite pertinently, as it seems to us, — that, until 
better known, Capnodium Citri and Antennaria eleophila can scarcely 
be considered distinct from Fumago salicina.* The specimens from 
* “Donec melius cognoscantur, a Fumagine salicicola supra descripta egre 
etiam discriminantur, nisi sede sibi singulis assueta, tum /’umago Citri, Persoonio 
seu Capnodium Citri Montanio; tum etiam Antennaria eleophila, Montanio,” &¢.
