FUNGUS FORAYS, 1883. 
years.” Perliaps the most interesting specimens found were some 
very large Ag. {Amanita) excelsus, and a cluster of Ag. {Hypho- 
loma) storea. 
This completes our brief record of the Fungus Forays of 1883. 
No frost, in the neighbourhood of London, occurring till the 13th 
of November, the Fungus season has this year been prolonged 
later than usual. 
ON THE LICHENS IN DR. WITHERING’S 
HERBARIUM. 
By the Rev. J. M. Crombie, F.L.S. 
Having recently been engaged in determining Dr. Withering’s 
lichens now in the Herbarium at Kew, I here record the results 
of my examination. The lichens were contained in a small cabinet, 
each drawer of which had numerous divisions in which the 
specimens were arranged according to the order of the “ Arrange- 
ment of British Plants ” (Edition hi.), of which they are illustra- 
tive. Amongst the specimens which it contains are many from 
Dickson, Relhan, Griffith, and not a few from Robert Brown. 
Those from Dickson are especially interesting and valuable in the 
absence of his Lichen-Herbarium, of which no trace can be found, 
though it is no doubt somewhere in existence. Though sometimes, 
as in all old Herbaria, several distinct species appear under the 
same name, yet in what follows, the lirst identification immediately 
after Withering’s own name, may, in most instances, be regarded 
as exclusively denoting the species, of which he gives his own 
short diagnosis. 
A. Substance like powder. 
Of the few species enumerated in this section there are no 
specimens, but they are evidently, as in other Herbaria, only 
leprarioid states of other lichens. 
B. Crustaceous, granulated. 
(1) With Black lines. 
L. Tcvi^os>xis = Dichcena rugosa (Fr.), — (specimen from Dickson). 
It. scriptus = Grap/izs scripta (Ach.), — (specimen from Relhan) 
and = Graphis dendritica (Ach.), — (specimen from Dickson). 
Var. 2. — (?) Hypoxylum fuscum, Fr., as it appears, but 
without spores, — (specimen from Griffith). 
(2) With Tubercles. 
It. fa,^XTievi^ = Pertnsaria amara (Ach.), sterile, and P. gr/oJzz/z/z'ra 
f. discoidea (T. & B.), — (specimens from Dickson). 
Var. 2. — Phlyctis agelcea (Ach.), — (specimen from Dick- 
son, s.n. Lichen carpineus). 
It. l>etulinus. Of this there is no specimen, but it is evidently 
some young state of a PerUisaria.
