I doubt if Penicillwn Bioti be different from Penicillum 
glaucum. The latter is produced in all mucus, sweet, and 
vegetable acid solutions, also in solutions of salts which con- 
sist of vegetable acids. 
Gardner has discovered a new phosphorescent fungus in 
the Brazils. Description of a New Phosphorescent Species 
of Agaricus, by George Gardner ; with Bern arks upon it by 
the Eev. M. J. Berkeley. Hooker’s Journal of Botany, vol. ii. 
(1840), p. 406. It belongs to the tribes of pileo-eccentrica, 
and Berkeley states, that it might be classified in the sub- 
genus Panus of Fries. The characters of it are, Pileo 
carnoso-coriaceo, subindfundibiliformi, glabro, flavo, lamellis 
longe decurrentibus pallidioribus, stipite brevi, coriaceo, gla- 
bro, cinerascente. Hab. in Brasilia, ad folia Palmarum, quae 
ab incolis dicuntur Pindoha. During a dark night, at the 
commencement of the month of December, in the town da 
Natividade, in the province Goyazes, Gardner witnessed some 
boys knocking about a shining fungus with sticks; this in- 
duced him to get the perfect fungus, in which he succeeded, 
and thus was enabled to give a description of it. Berkeley 
adds, that there are several species of fungus which emit 
light in the dark, and mentions the Ag. olearius, Dec. ; he 
also proposes to change the name of Ag. phosphor escens into 
A. Gardneri. It is a question whether these species of fun- 
gus are always shining. The Rhizomorphoe do not shine 
under all circumstances. 
Chrysomyoca ahietis, a fungus and eruption (exanthem) of 
the red fir, is described by F. Unger. See Froriep’s Neue 
Notiz. xvi. (1840), p. 10. The following is an abstract of 
Unger’s remarks on its comparative pathology ; Vienna, 1840. 
He first gives an exact anatomical description of the leaves 
of the fir, and then proceeds to the description of the exan- 
them. It is found on the last annual shoot, and on almost 
every leaf. There are yellowish discolourations on the upper 
side of the leaf, and similar discolourations on the under side; 
also one or several rust yellow spots, but only where there 
are rows of stomates. The yellow rust spots are elevated 
into a wart-like substance, and the upper membrane is torn
