PROCEEDINGS OF THE SOCIETY. 155 
Campsie range of hills. The day was very fine, and the view 
from the summit was much enjoyed by the members present. 
The hill did not seem to be rich in vegetation, as no plants of 
any rarity were observed. 
Mr. D. A. Boyd showed specimens, from Moffat and Duntocher, 
of ‘silk-button galls” produced on the under surface of oak-leaves 
by Weuroterus numismatis (Oliv.) Mayr, one of the Cynipide. 
These galls, which adhere closely to the leaf-surface, are round, 
depressed in the centre, and covered with silky-brown hairs. 
Mr. Boyd also made some remarks on the characters and 
affinities of the Magnoliacez, and exhibited a specimen of the 
fructification of the Tulip-tree (Liriodendron tulipifera, Willd.), 
which has its carpels arranged in the form of a cone. 
Mr. George Russell showed a fine specimen of Oncidiwm cartha- 
genense, Willd., an exotic orchid with racemes of red-spotted 
flowers. In this species the pseudo-bulb is absent, but its place 
is supplied by the fleshy green leaves which store up abundant 
nutriment for the growing plant. 
Professor Thomas King made some remarks on the conference 
of the Cryptogamic Society of Scotland held last week at Moffat. 
Numerous specimens of Fungi, gathered at excursions in connec- 
tion with the conference, were also exhibited by him. Among 
these were Agaricus (Amanita) virosus, Fr., A. (A.) mappa, Fr., 
A. (Tricholoma) sulphureus, Bull., Canrtharellus infundibuliformis, 
Scop., Lentinus cochleatus, Pers., Polyporus perennis, Linn., T're- 
mellodon gelatinosum, Pers., Craterellus cornucopioides, Linn., 
Pexiza (Cochlearia) badia, Pers., Ustulina vulgaris, Tul., and 
Anthina flammea, Fr. 
Professor King also reported that Lactarius fuliginosus, Fr., and 
Polyporus fragilis, Fr., had since been gathered at Moffat by 
the Chairman (Mr. Stewart), these being additions to the list 
of nearly 200 species observed during the conference. In the 
course of some remarks on the various specimens, he stated that 
Tremellodon gelatinoswm had already occurred in the South of 
Scotland, examples having been obtained during the conference 
of the Cryptogamic Society held at Dumfries in 1883. It was 
recently discovered in four localities near Moffat, and therefore 
seems to be widely distributed throughout Dumfriesshire, 
although it has not yet been detected in any other Scotch county.
