In the vicinity of Floeberg Beach, a single small specimen. 



77. Lecidea scrobiculata, Th. Fr. Crusta crassa, contigua, 

 verrucis jugisve ina^quali, supra plus minus rimosa insuperque 

 tenuiter rimulosa, albida, sordide ochroleuca argillaceave ; hyphis 

 non amyloideis ; apotheciis majusculis, atris, disco scabridis, pri-

 vatis saepeque quasi pedieellatis, convexis, immarginatis, varie 

 flexuosis tuberculatisque ; sporis minutissimis vel subminutis, 

 globosis vel globoso-ellipsoideis. 



On stones in many localities in the vicinity of Floeberg Beach, 

 even at an altitude of 500 feet ; Lincoln Bay. 



From L. elata, as a subspecies, under which I, in ' Lich. Spitsb.' 

 p. 41, described this plant, it is very distinct, and of a very pecu- 

 liar habit. It is much more allied to L. brachyspora. To 

 complete the above-given diagnosis may be added : — Thallus 

 usque ad 5 mm, et ultra crassus, neque K neque Ca CI tinctus ; 

 apothecia 1-2 mm. lata, adultiora verrucis elevatis vulgo insiden- 

 tia, unde quasi pedicellata, subtus plus minus distincte pallida ; 

 hypothecium omnino incoloratum ; paraphyses graciles, cohae- 

 rentes, apice plus minus obscure olivaceo- vel smaragdulo-fuli- 

 ginese ; asci clavati ; sporse 0006-0*008 mm. longse et 0005- 

 0'006 mm. crassae vel diam 0005-0*006 mm. metientes ; gelatina 

 hymen, iodo caerulescens, dein nonnihil sordidescens ; spermatia 

 acicularia, recta (vel leviter curvula), 0012-0014 mm. longa. 



78. Lecidea despecta, n. sp. Crusta tenui, riinuloso-diffracta, 

 albida, hypothallo csesio imposita, vel indistincta ; hyphis medul- 

 laribus non amyloideis ; apotheciis sessilibus, diu planiusculis et 

 margine crassiusculo cinctis, demum nonnihil convexis margme
