ASCOBOLUS ATROFUSCUS. Phillips. 
By oversight Mons. Boudier has conferred the name of Ascohohs 
carhonicoia upon the species which he confounded in his Memoir 
(published in “ Annales des Sciences Naturelles”), with Ascohohs 
viridis^ Curr. He evidently had not observed the description by 
Mr. W Phillips in “ Grevillea,” Vol. II., p. 186 (June, 1874), of 
Ascoholus atrofuscus, Ph. & PL, with its synonym ^sco5o/ws viridis, 
Bond. Mem., t. 5, fig. 4, to which must now be added, as a seeond 
synonym, Ascohohs carhonicoia, Bond. Bull. Soc. Bot. France, 
1878, p. 310. The same species occurs, with its correct name, at 
p. 357 of the same journal.

Belonia Nerculana. Hazs. Grevillea, vi., p. 109. — Having 
received intimation from Dr. Kehm that this species had already 
been published as Segestrella herculina, Rehm, we communicated 
wdth Prof. Hazslinszky, who informs us that it was first published 
by Nylander as Verrucaria hungurica, Nyl., and that the more ac- 
curate name would be Belonia hungarica (Nyl.), Hazs. The genus 
depends upon the views of the different authors. Koerber’s Belonia 
is not Ny lander’s Belonia ; one having paraphyses, the other 
none.
