NEW LICHENS FROM KERGUELEN's LAND. 21 



25. Lecidea subalbicans, Nyl. Thallus whitish, subopaque, thin, 

 minutely areolato-diffract, subrugulose (K4- yellowish) ; apothecia 

 brownish, small, plane, the margin paler ; spores ellipsoid, paraphyses 

 not well discrete ; spermatia arcuate. Approaches to L. albicans, 

 Nyl. Saxicole. 



26. Lecidea granulosiila, Nyl. Differs from L. enteroleuca, Ach., 

 chiefly in the yellow, minutely granulose or subleprose thallus. 

 Apothecia convex, immarginate, entirely whitish within. Saxicole, 



27. Lecidea incuriosa, Nyl. Thallus whitish, thin, granulated or 

 granulato-subareolate, unequal (K -(-yellow) ; apothecia black, at length 

 convex, immarginate, concolorous within ; spores Snae, brown, 1- 

 septate. Belongs to the section of Lecidea (or perhaps rather Leca- 

 nora) spuria, Schser. Saxicole. 



28. Lecidea subtristis, Nyl. Thallus brown, very thin, smooth, 

 rimulose ; apothecia black, plane, margined, whitish within ; spores 

 Snae, brown, bilocular. Spermogones not seen. Saxicole. 



NEW LICHENS FROM KERGUELEN'S LAND. 



Br THE IIev. J. M. Crombie, F.L.S. 



No II. 



In addition to those enumerated in the Journal of Botany, 

 1875, pp. 333-335, there occur also the following novelties in the 

 collection made by Mr. Eaton. 



1. LicMna antarctica, Cromb. At first sight not unlike some small 

 state of L. confinis. Apothecia and spermogones enclosed in subglo- 

 bose, crowded, fastigiate clavuli ; spores ellipsoid ; spermatia oblong. 

 Saxicole. 



2. Lecanora diphyella^ Nyl. A peculiar species, allied apparently 

 to Lecanora diphyes, Nyl., but differing in the smaller apothecia, the 

 black hypothecium(K-f- violet-purple), and the thicker spores. Sper- 

 mogones not seen. Saxicole. 



3. Lecanora broccha, Nyl. Thallus whitish, very thin ; apothecia 

 brown, moderate, psoromoid in appearance ; spores ellipsoid, simple. 

 Spermogones not seen. Caulicole and muscicole. 



4. Lecanora sublutescens, Nyl. Entirely similar in appearance to 

 Z. lutescens, DC , but saxicole, and the spores not seen rightly 

 evolute. Thallus sulphur-coloured, subleprose (Ca. CI. -j- saffron- 

 coloured). 



5. Lecidea sub assentiens, Nyl. Allied to Z. diasemoides, Nyl., but 

 differing in the somewhat smaller spores and longer spermatia. In 

 external appearance it suficiently agrees with Z assentiens, Nyl., but 

 a microscopical analysis shows it to be quite different. Saxicole. 



6. Lecidea asbolodes, Nyl. Thallus fuliginous, thin, determinate ; 

 apothecia black, margined, sufficiently small ; spores shortly ellipsoid, 

 paraphyses slender. In external appearance it bears a near resem- 

 blance to Lecidea leiotea, Nyl., which, however, differs in the immar- 

 ginate apothecia and the thicker paraphyses. Saxicole.
