* 



saepe curvulae, epithecium luteo-fuscescens, paraphyses gracilescentes, 



hypothecium cum perithecio nigrum. Iodo gelatina hymenialis cseru- 



lescens, deinde vinose rubescens. 

 Facies externa fere Sarcogynes simplicis (Dav.), sed revera stirpis Lecidea 



coniopis. Spermatia arcuata, longit. 0*01 6-0' 022 millim., crassit. 



0*0005 millim. Variant apothecia magis gyroso-corrugata et aggregata. 

 On rocks. Royal Sound and Swain's Bay. 



Probably not uncommon. 



L. cerebrinella, Nyl. Similis L. cerebrincB (Ram.), sed minor; 

 apotheciis minoribus (latit. circiter 0*5 millim.) et sporis minoribus 

 (longit. O'009-O-Oll millim., crassit. 0006-0007 millim.). Iodo 

 gelatina hymenialis leviter caerulescens, dein vinose fulvescens. 



Apothecia valde plicato-corrugata. Thallus aibus tenuis rugulosus, K+ 

 (flavens), evanescens quidem adest, at minime proprius. Verus thallus 

 L. cerebrinella videtur obscure cinerascens tenuissimus continuus 

 obsoletus. 



On rocks. 



L. geographica (I/.)* The specimens are entirely similar to the 

 European plant. Spores 0024-0031 millim., crassit. 0012-0014 

 millim. 



On rocks. At all the stations. 



Yery sparingly gathered. This is the only crustaceous species 

 from Kerguelen in which the medulla gives a bluish reaction 

 with I. 



Tribe Pyrenocarpei. 



Verrlcaria tessellatula, Ay/., sp. n. Thallus cinereo-fuscescens 

 sequabilis areolato-diffractus, sat tenuis (crassit. circiter 03 millim.) ; 

 apothecia innata, pyrenio incolori, solum supra (ostiolo parum pro- 

 miuulo) nigra ; spore 8nae ellipsoideae, longit. 0010-0015 millim., 

 crassit. 000/-0008 millim. 



Affinis Verrucarice virenti, Nyl., et V. Nova Anglice, Tuck., sed mox 

 distans thallo laevigata (fere ut in V. polysticta 9 Borr., et areolis etiam 

 magis discretis), sporis brevioribus &c. Gonidia, diametro transverso 

 0*016-0-022 millim., ssepius 2 vel plura syngonidio (crassiusculo) 

 juncta, interdum subseriata (chroolepoidea). 



On rocks. Swain's Bay and Royal Sound. 



Very sparingly gathered; and the specimen from the latter 

 station atypical, in consequence of having been submersed in 

 water. 



V. obpuscata, Nyl., sp. n. Thallus umbrino-nigricans 



nigro 



niastoideo-prominulo (latit. basi fere 0\'i millim.), epithecio vix iui-
