PLANTS FROM NEW CALEDONIA. 
Nylander’s specimen from Penang is sterile. The above, which is alike 
in thallus, bears numerous apothecia up to 2 mm. wide, the margins crenate 
when young but becoming subentire, the margin and under side beset with 
black setze which tend to dhe less visible in the more developed fruits ; the 
hypothecium is colourless; hymenium 50-60 y high; asci clavate 40-50 u x 
10-12 4; paraphyses concrete, the tips involved in reddish-brown mucilage ; 
spores small, ovoid, or subglobose, 5u x Tu. 
Tt would be necessary to secure fertile specimens from Penang to be quite 
sure of the specific identity of the specimen from New Caledonia. The 
black setze, up to 1 mm. long, are a distinctive feature of the amens : 
they recall those of Parmelia tiliacea subsp. earporhizans (Tayl.) N
