cipal harvest of the Islanders, who collect them in large quantities for 
sale to the farmers on the mainland, who use them extensively as 
manure. Fine examples of some of the more showy species of the 
Floride section were observed, affording sufficient indication that 
some of the rarer kinds might be found if properly sought for.

Contributions to British Lichenology. 
By Joun G. Baker, Esq. 
Dourtine part of the past winter I have been occupied arranging my 
collection of lichens, and examining the accumulated stores of the 
Yorkshire Philosophical Society ; and have also been favoured with 
the loan of an extensive series of specimens, belonging to my friend 
I. Brown, of Ackworth. Through the medium of the ‘ Phytologist’ I 
propose to describe a few species, or forms, which have either not 
been known before as inhabitants of Britain, or have been in some 
way involved in confusion or misunderstood. 
1. Evernia vulpina (L. vulpinus, Z.) — Thallus pale yellow, much 
branched in a divaricate manner, irregularly angular and lacinose.

On trunks of trees, Killiney Hills, Co. Dublin, 1842, R. Jacobs in 
herb. J. Brown. Several examples are also included amongst an 
extensive series of English specimens, collected by the Rey. J. Har- 
riman, preserved in the Daltonian herbarium, which are not labelled 
with their special stations. This beautiful and conspicuous lichen 
has been well known upon the Continent from the days of Haller and 
Linneus downwards. In the ‘ Enumeratio,’ Scherer marks it as 
* Some of these references are taken on the authority of the ‘ Lichenographia 
Europea’ and the ‘ Enumeratio,’ as I have not had an opportunity of consulting 
all the works and fasciculi mentioned.
