 minora) marginata, margine granulato tandem fiexuoso, excipulo thallino 

 albido V. dilutissime colorato gonidia continente, excipulo proprio fibrato 

 supra evanescente, parapliysibus non bene discretis apice minute granulosis 

 non dilatis. Sporae in ascis saccatis subarcuataa v. leviter curvatse aciculari- 

 fusiformes S-septatse, longit. 'OSS, crassit. '004 mm.

Probably Babington'sL.ptmem, Ach. (Flora N.Z., p. 292). Comparing 

 our lichen with Leighton's L. jninicea (Ceylon Lichens, No. 62), it is seen 

 that the thallus of the latter is fusco-cinereous, while the spores are '07 mm. 

 in length, and the septse from 7-15 in number (v. fig. No. 11, b.), and these 

 measurements agree with Nylander's figure, v. Nylander's Lichenes Novo- 

 Granatenses, p. 82, fig. 7, tab. 1, reproduced here to the same scale as all 

 the other figures are drawn, v. fig. No. 11, c.

 juniore pallide fusca — margine concolore tenui, excipulo dilute fuscescente a 

 lateribus v. a basi et lateribus per lineam tenuem fuscam contento, strato 

 subhymeniale e pseudo-gonidiis liberis sph^ricis incoloratis — aliis minutis 

 aliis sat grandibus — formato, paraphysibus brevibus subcrassis adglutinatis
