COLLECTED AT THE CAPE OF GOOD HOPE. 173 



This species is referred to the section of i. sophodes, or almost 

 to that of L. atrocinerella, NyL 



On rocks (sandstone) ; rare. 



Lecanora glauco-li vescens, NyL, sp. n. Thallus glaucescens tenuis 

 rimosus, hypothallo nigricante limitatus ; apothecia lurido-fusca vel 

 livido-fusca, plana (latit. 0*5-0*6 inillim.), subzeorina vel margine 

 thallino tenui evanescente cincta ; sporae 8nae, incolores, ellipsoideae, 

 1-septatae, longit. 0009-0*01 1 millim., crassit. 0*004-0005 millim. ; pa- 

 raphyses graciles, sursum clava fuscescente. Iodo gelatina hymenialis 

 vinose rubens. Spermogonia arthrosterigmatibus munita; spermatia 

 oblonga, longit. 00035 millim., crassit. 00005 vix superantia. 



This species belongs to the section of L. disparata. 



On rocks ; only sparingly gathered. 



L. ELiEOPHiEA, NyL, sp. n. Thallus olivaceus, depresso-granulatus vel 

 potius granulato-rugosus, tenuis, determinatus (hypothallo nigricante 

 indistincto aut magis visibili limitatus) ; apothecia fusca, convexula 

 (latit. 0*5-0*7 niillim. ), margine thallino tenui integro cincta aut magis 

 convexa margine hoc excluso ; sporae 8nae incolores ellipsoideae aut 

 fusiformi-ellipsoideae, uniseptatae, longit. 0012-0*016 millim., crassit. 

 0004-0*006 millim. ; epithecium fuscum ; paraph} r ses gracilescentes. 

 Iodo gelatina hymenialis vinose rubescens. Spermogonia arthrosterig- 

 matibus munita longiusculis sat breviter articulatis (articulis crassit. 

 0*002-000*3 millim.); spermatia ellipsoidea vel oblongo-ellipsoidea, 

 longit. 00015-00025 millim., crassit. vix 0010 millim. 



This, like the preceding, as shown by the character of the sper- 

 mogones, belongs to the section of L. disparata, although it might 

 otherwise be readily supposed to be of the section of L. erysibe. 



On rocks ; rare. 



L. galactiniza, NyL, sp. Thallus albidus tenuis subareolato-rimosus ; 

 areolae ambitu interdum subcrenatae; apothecia fusca parva (latit. 

 0*3-0*5 millim.), margine thallino integro vix prominulo cincta; sporae 

 ellipsoideae, longit. 0*010-0*013 millim., crassit. 0*006-0*007 millim. ; 

 paraphyses gracilescentes non bene discretae et supra granuloso-in- 

 spersae ; epithecium fuscescens. Iodo gelatina hymenialis caerulescens, 

 dein thecae violascentes. 



L. galactinella, NyL (in Obs. Lich. Pyr. Or., p. 53, erroneously 

 written as " L. galactina "), differs from L. galactina, Ach., espe- 

 cially in the brown smaller apothecia ; but L. galactiniza, which 

 is subsimilar, is at the same time distinguished by the reaction of 

 the thallus, K+ , yellow; wherefore it may belong to the section 

 of Id. subfusca. 



On rocks (quartzose) ; apparently rare.
