FIFTY YEARS OF BOTANY IN BRISTOL. 33 
and Jungermannia Wilsoniana. The latter is a small foliose plant 
that seldom fruits in Britain, but fruits freely with us. Frullania 
dilatata, with a habitat on the bark of trees throughout the district, 
is of interest because it harbours a small rotifer (Callidina 
symbiotica) in pitchers .at the back of its leaves. Lunularia 
vulgaris, with Marchantia polymorpha, has nourished and fruited 
abundantly around our Cathedral Close, and between kerbstone 
and gutter in some of the back streets of Bristol. Hepatics and 
their kindred orders have long been under observation by Sir 
Edward Fry and his daughter, Miss Agnes Fry. Miss Fry reports 
that Riccia sorocarpa was new to Somerset when she found it on 
Failand Hill a few vears ago ; and Fossombronia pusilla. in fruit, 
has been gathered by her at Failand in the month of February. 
Lichenes. There is a long list of species in the Victoria County 
History of Somerset ; but Mr. Watson remarks that very much 
remains to be done in regard to their distribution. To those who 
feel inclined to enter upon this branch of research it may be hinted 
that they can have the advantage of an accessible referee in the 
present Secretary of the B.N.S., Dr. Darbishire being a European 
authority on lichens. And a collection of British Lichens has its 
place in the University Herbaria. 
Fungi. Mr. Cedric Bucknall's scrutiny of Bristol fungi has 
already been referred to. He eventually gave us a series of lists 
illustrated by excellent drawings of the more interesting species. 
His Part I. appeared in 1878, and the work ended with Part XIII. 
in 1891. Mr. Bucknall has furnished me with the following notes 
that give details not hitherto published : — 
" The Fungi of the Bristol District contains 1,431 species 
collected between 1876 and 1891, with figures of those newly- 
discovered. Of these more than 100 species were new to Britain or 
to science, consisting of about 30 Agaricini with 5 other 
Hymenomycetes ; 9 Melanconei ; 18 Elvellacei (Pezizse, etc.) ; 1 
Phacidiacei ; and 41 Pyrenomycetes (Sphceriacece, etc.). Of the 
20 species new to science seven belong to the Agaricini and are 
mostly large and conspicuous plants: — Agaricus Bucknalli 
B. and Br., A. electicus Bucknall, A. eustygius Cooke, Cortinarius 
nitrosus Cooke, C. testaceus Cooke, C. bicolor Cooke, Paxillus 
lividus Cooke. The remaining new species are mostly small or 
microscopic, viz : 6 Elvellacei, 1 Phacidiacei and 7 Pyrenomycetes. 
Of the figures in Cooke's Illustrations of British Fungi 
(Hymenomycetes) 8 vols. (1881-1891) forty-four are taken from my 
coloured drawings of Bristol specimens ; and about a dozen other 
Bristol Fungi are figured in that work from drawings made b^ 
Berkeley, Broome, W. G. Smith or M. C. Cooke himself." A 
notice of the more prominent mycologists who have worked in the 
Bristol district is contained in Mr. Bucknall's paper in the Victoria 
History of Somerset, Vol. I., p. 59. 
Mycetozoa. Miss Agnes Fry writes respecting this remarkable 
family that they were but little studied prior to the inception of
