IV.—The Ferns, Mosses, and Fungi. 
By Dr Buchanan White, F.L.S. 
(1) THE FERNS AND THEIR ALLIES. 
From the general dryness of Kinnoull Hill, it is not on 
the whole very rich in ferns, and possesses one species 
only which has any claim to be considered rare. The 
species in question is the Scaly Spleenwort (Asplenium 
CeterachJ, which has been known to grow there for about a 
century, as the locality is mentioned in Lightfoot’s Flora 
Scotica. It is by no means abundant, and I do not intend 
to indicate the precise locality, but should any one find it, 
it is hoped that they will not do anything to make the 
plant rarer than it is at present. 
Three other ferns are interesting from the places where 
they grow, as they are within the municipal boundaries. 
The most remarkable of these is the Brittle Bladder-Fern 
f Cystopteris fragilis), of which a single specimen grows 
(or grew) on a dry wall on the Muirhall Road, a very 
curious place for a plant which prefers damp and shady 
rocks and banks. I know no other locality for it in the 
district. It is a species, however, that grows very readily, 
and I find it springing up of itself in my rock-garden, 
where it is the only fern that is self-sown. The other 
town ferns are the Wall-rue ( Asplenium ruta-muraria), 
and the Male Fern ( Lastrea filix mas). Of these, the first 
abounds on the back of my garden wall (it is common on 
other walls outside the municipal boundaries); and the 
second on the top of a wall at Bowerswell. (Both species 
I have seen even nearer the centre of the town.) Another 
fern—the Hart’s Tongue—has been reported to me as 
having been found not far from Kinnoull churchyard, and 
I believe the report was correct; but whether it is there 
now, or whether it could be claimed as a native, I cannot 
say. The other ferns of Kinnoull Hill do not merit any 
lengthy notice. The Oak Fern has been reported to me, 
but I have not seen it; nor can I remember ever having 
seen the Bracken, whose absence is more remarkable. Of 
the allies of the ferns there are two, of which one only 
needs special mention, namely, the Fir Club Moss (Xyco- 
podium Selago). Of this I once saw a single specimen 
close to the highest point of the hill. 
(2) the MOSSES. 
The moss flora of the hill has not been worked to the 
extent that it deserves. In fact, almost all that we know 
of it is the result of a very few days’ labour when I was 
interested in mosses some years ago. The result of that 
work is a list of upwards of 120 species, or more than one- 
fifth of the British mosses; and the list could probably 
have many additions made to it by further explorations. 
Though the cliffs afford the best field to thebryologist, the 
woods and the banks of the river at Barnhill yield some 
species that are not on the rocks. Of the rock-loving 
mosses, the most interesting are Grimmia subsquarrosa, a 
species which was first discovered on Kinnoull Hill during 
the days I have mentioned, but which has since been 
found in various other places; and Grimmia orbicularis, a 
species of very local distribution. Amongst the wood- 
frequenting species may be mentioned the beautiful 
ostrich-plume feather-moss,—the most lovely, I think, of 
all our larger mosses ; and the very rare Campylopus 
brevifolius. Of the river-side mosses, Lcskea polycarpa 
and Thuidium recognitum are the most notable for their 
rarity. As illustrating the way in which species may 
disappear from the flora of the district we have under 
consideration, we may instance Ehynchostegium murale.
