There is a variety with larger apothecia, narrow black subhymenial stratum, and broad 
rellow thalline hypothecium. In other respects similar. 
44, PHYSCIA MELANOCLINA, sp. n. (Tab. VII. fig. 10.) Thallus membranaceus stra- 
mineo-albus у. glauco-albus arcte matrici toti adglutinatus glomerulosus, glomerulis 
sorediosis, laciniis lobato-crenatis rugosis confluentibus in centro congestis, subtus 
nigricantibus v. fuscescentibus extremis partibus incoloratis. Apothecia rubiginosa 
mox livido-fusca, disco plano tandem subconvexo, margine pallido tenui prominente 
subintegro, excipulo mere thallino albo ; hymenium ex hypothecio fusco-atro enatum, 
paraphysibus adglutinatis. Spore in ascis cylindraceis, fuscee, fusiformi-ellipsoidex, 
l-septate, longit. ‘018, crassit. "006 mm. Ad truncos arborum. 
An P.picta? Р. picta, No. 164, Spruce. Lich. Amaz. et And., is closely allied; but 
the thallus is free from soredia, and the spores 4-locular, the cells united by a central 
tube. In Montaigne's description of Р. picta the remarkable dark-coloured hypo- 
thecium in contrast with the white thalline excipulum is not noted.
