462 MR. G. MASSEE—REDESCRIPTIONS OF 
Retain of Berkeley’s Types of Fungi. By Grorex

Herbarium, Kew.

(Prarzs XVI.-XVIII.) 
Tue magnificent mycological herbarium of the Rev. M. J. 
Berkeley, M.A., F.R.S., presented to Kew in 1879, illustrates 
the numerous mycological publications by the author, dating 
from the appearance of the volume on Fungi in Smith’s ‘ English 
Flora’ (1836) to “Notices of Fungi collected in Zanzibar” 
(1885). The collection contains just over 11,000 species, of 
which 4866 are types described by Berkeley, either alone or in 
union with other authors. Many of the species were established 
half a century ago, consequently the diagnoses are brief, the 
characters comparative rather than positive, dealing almost 
entirely with superficial features, and hence are not sufficiently 
exact to secure identification of the species intended at the 
present day, when microscopic characters are considered of 
primary importance. 
The object of the present contribution is to furnish full 
descriptions, with figures, of Berkeley’s types, drawn up in 
every instance from the actual specimens used by the author in 
the first instance. The name originally given by Berkeley is in 
every case retained ; the synonymy will indicate what changes have 
been introduced by other authors.

There is no specimen of the present species at Kew, and 
for that reason it would not have been alluded to here had 
not Cooke figured it in his * Mycographia? with the assuring 
remark, “figured from drawings communicated by the Rev. M. 
J. Berkeley." On investigating this matter, it proved that 
Berkeley’s drawings consisted of a pencil sketch of the smallest 
figure in Cooke's illustration, marked “n. s.," and two spores, 
marked “+355,” with the following, “ Helvella pusilla, B. & C., 
Behring's Straits. U.S.E.E. Stem whitish, hollow." The second
