VIlI.—Memoir on the Spermogones and Pycnides of Filamentous, Fruticulose, and 
Foliaceous Lichens. By W. Lauper Linpsay, M.D., F.L.S. Communicated 
by Professor BaLrour. 
(Read 7th March 1859.) 
Preface. 
The following Memoir contains the results of researches made during the last 
three years. My investigations were originally directed to British lichens only, 
but they have subsequently and gradually embraced lichens from all parts of the 
world. The majority of Scotch species examined were collected by myself while 
on botanical tours in various parts of Scotland during the last ten years. Low- 
land species were collected chiefly in the counties of Perth, Edinburgh, and Dum- 
fries; but also in Forfar, Fife, and others of the midland counties. In order to study 
alpine species I made a special tour among the highest of our Scotch mountains in 
the summer of 1856. I then visited the Braemar Highlands, Ben Lawers, Ben 
Nevis, and the Coollin Hills, in Skye. Ihave likewise studied the lichens of Don, 
now in the possession of Mr M‘Naz, of the Royal Botanic Garden, Edinburgh ; the 
lichens collected by Maucuan, M‘Mizan, and others, in the Herbarium of the Bo- 
tanical Society of Edinburgh ; those collected by the late ALEXANDER MENZzIgs, in 
the Menziesian Herbarium belonging to the Botanic Garden of Edinburgh; those 
collected by Borrer, Hooxer, CARMICHAEL, GARDINER, and others, in the magni- 
ficent Hookerian Herbarium at Kew ; and I have also examined the valuable her- 
barium of the University of Edinburgh, under the care of Professor BaLrour, and 
the herbarium of Dr Grevitte. The examination of specimens in the herbaria of 
Hooker, Menzizs, and Don, has been especially valuable, in so far as they contain 
species authenticated by the earlier British lichenologists,—lichenologists to whom 
I am proud to have an opportunity of expressing my deep obligations. Iam fur- 
ther indebted for interesting specimens of Scottish lichens—now in my own her- 
barium—-to Mr James Harpy, of Penmanshiel, in Berwickshire,—to Mr ALEx- 
ANDER CROALL, of Montrose, and to Professor GEorGE Lawson, of Kingston, Canada 
West. The two latter gentlemen supplied me with many alpine species, chiefly 
from Clova and the Forfarshire hills. For English species I am indebted to the 
kindness of the Rev. W. A. Lerauton, of Shrewsbury, who has repeatedly sent me 
lichens from Shropshire, and Wales, more especially; to Mr Wiuram Moupo, of 
Cleveland, Yorkshire; to Dr Carrineron, of Yeadon, near Leeds; and to Dr 
Deieuton, of Clapham, near Lancaster, all of Whom have frequently sent in-
