Авт. XXXIX.— Descriptions of some New Zealand Lichens, collected by 
John Buchanan in the Province of Wellington. By James STIRTON, 
M.D., Glasgow. Communicated by JoHN BUCHANAN. 
[Read before the Wellington Philosophical Society, 16th January, 1874.] 
Beomyces pertenuis, Stirton. 
THALLUS scarcely discernible ; apothecia pale buff, concave, with a paler border, 
attached by a central axis; spores eight, exceedingly minute, elongate-elliptical, 
apparently simple, although there are occasional indications of a septum which 
a j objective cannot distinctly resolve, in nearly single file in asci, which 
scarcely differ in size or thickness from the ordinary paraphyses. А section 
presents the characteristic appearance of lichens of this genus. In such an 
extreme case as this, it is necessary to remark that I have carefully discriminated 
between the oil globules that are seen in the paraphyses of one or two of the 
species of this genus and these minute spores, which still preserve their outline 
when free of the asci, and which, by the aid of a better objective, I find now 
are nearly constantly three-septate.
