Art. XXXIX. — Descriptions of some New Zealand Lichens, collected hy 

 John PuchoMan in the Province of Wellington. By James Stirton, 

 M.D., Glasgow. Communicated by John Buchanak. 



\Read before the Wellington PMlosoplucal Society, 16th January, 1874.] 

 Pceomyces p)ertemds, Stirton. 

 Thallus scarcely discernible ; apothecia pale buff, concave, with a paler boi'der, 

 attached by a centi-al axis; spores eight, exceedingly minute, elongate-elliptical, 

 apparently simple, although tliere ai'e occasional indications of a septum which 

 a -^ objective cannot distinctly resolve, in nearly single file in asci, which 

 scarcely differ in size or thickness from the ordinary paraphyses. A 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 thesepminute 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.
