134 LICHENOLOGICAL MEMORABILIA. 



79. "Lecidea impavida. Th. Fr.— Inalpibus Njammelst et Nam- 

 mats." — A very curious and distinct looking lichen, carefully cha- 

 racterized in Th. M. Fries " Lichenes Spitzbergenses," p. 42. 



80. " Lecidea perfidiosa. Nyl. — In rupibus muscosis infra 

 Snjarrak." Nyl. Scand. 244. Probably the true plant, but state 

 of specimen unsatisfactory for correct examination. 



81. " Spoxastatia Moxio (.Ram.) (3 coxacina (Smrflt.) — In alpibus 

 Nunnats & Passo prope Aktse." A poor specimen, externally 

 resembling Lecidea nitida, Sch^r. (K — C — ), but polysporous, 

 and according with Sornmerfelt's description in his Suppl. Fl. 

 Lapp., 142. 



82. "Buellia insignis. (N^g.) — In terra muscosa alpis Snjarrak 

 = Lecidea insignis var. muscorum, (Wulf.), Hepp. 40, Fellm. 201. 

 Anzi Ital. Sup., 292. The var. corticicola Korb., is Hepp. 39, 

 Anzi Ital. Sup., 297. Both vars. have reaction, K yellow C orange 

 or orange-red. The spores are brown, 1-septate, and the hypothe- 

 cium dark fuscous. I have the var. corticicola from Bornere Pool, 

 Shropshire (1871), not as yet recorded as British. 



83. "Buellia Rittokensis. Hellb. — In rupibus infra Rittok et 

 Nammats." A very remarkable lichen, well described by M. Hell- 

 bom in Kongl. V. A. Fordh. 1866, p. 463. On a black hypo- 

 tballus, the roundish, fuscobadious shining areolae, plane or concave, 

 with an elevated albopulverulent margin, are distantly and disper- 

 sedly scattered, and the larger black apothecia are sessile on the 

 hypothallus. The hypothecium is very large and thick, nigro- 

 fuscous, the hymenium very narrow, paraphyses cohaerent or indis- 

 tinct,' and spores 8, fuscous, very broadly and obtusely oblong or 

 ellipsoid, 1-septate. Reaction K — C — 



84. " Rhexcphiale coxonata. Th. Fr.— In terra muscosa infra 

 alpem Nammats." Assuredly a very distinct and beautiful species, 

 described in Th. M. Fries Lichenes Arctoi, p. 205, but I cannot see 

 any particular reason why it should be removed from the genus 

 Lecidea of Ach. & Nyl. into a new and separate genus. It is 

 Lecidea rhexoblejdiara, Nyl. Scand. 240 and 293. Leight. Lich. 

 Fl. 333. 



85. " Buellia coxacina. (Hoffm.) — In summo cacumine alpis 

 Passo prope Aktse." Identical with Fellm. Lapp. Or. 193, and 

 our British plant and Lecidea coracina, Ach. Leight. Lich. Fl. 

 307. 



86. " Rhizocaxpon geogxaphicum (3 alpicolum. (Wnbg.) — In 

 rupibus infra Njammelst." This specimen has reaction K yellow 

 then reel, whereas in L. alpicola (Sch^er.), the reaction is K — C — , 

 according to Schasr. 173, Hepp. 151, and specimens from Dr. 

 Nylander. The spores are colourless in a young state, but brown 

 1-septate when mature. Can it be L. atyestris, Scha^r. En. 107 ?
