 tionem purpurascenti-dissolventem ostendunt. Spermogonia non visa. 

 On rocks. Royal Sound. 



Perhaps not uncommon. 



Lecanora macrophthalma (Tayl.). Etiam forma apotheciis ni- 

 gricantibus. Sporre longit. 0*021-0*023 millim., crassit. 0-01 1-0-015 

 millim. 



Est e stirpe Lecanora cinereee. Maxime notabilis thallo CaCl + 

 (erythrinoso). 



On rocks. At all the stations. 



Apparently abundant.

 aequabilis, subrugulosus vel rugosus, hypothallo nigro limitatus. 

 Apothecia atra, in receptaculis demum nonnihil protuberantibus 

 recepta, margine thallino non prominulo, plana (latit. 0*8-1 '5 millim.), 

 subopaca, intus concoloria. Sporae 8nae incolores ellipsoidese, longit. 

 0-010-0-012 millim., crassit. 0*006-0*007 millim., totum apothecium 

 in lamina tenui visum obscure violascens. 



Affinis L. atrce, sed certe distincta species, differens jam thallo alio et 

 spermatiis curvulis (apice supero curvatisj brevioribus (longit. 0*009- 

 001 1 millim., crassit. vix 0*001 millim.). Thallus K+ (virescenti- 

 flavens. 



On rocks. At all the stations. 



Frequent. 



L. broccha, Nyl., sp. n. Thallus albidus tenuissimus (K+flavens); 

 apothecia fusca mediocria (latit. 1-2 millim.), margine thallino 

 crenato-dentato subplicato et involvescente recepta ; sporae ellipsoidese 

 simplices, longit. 0015-0*017 millim., crassit. 0*006-0*007 millim.; 

 paraphyses mediocres vel subcrassiusculae ; epithecium fuscum. Iodo 

 gelatina hymenialis cserulescens, dein incolor thecis violaceo-tinctis. 

 Spermatia bacillaria recta longit. 0007-0008 millim., crassit. 0*0007 



millim. 

 On decayed mosses, and on dead stems. Royal Sound. 



Apparently not uncommon. The apothecia in appearance are 

 as in Psororna, though their anatomic structure is not as in that 

 genus. As shown by the spermogones, it belongs to the section 

 of i. atra. The apothecia are rarely the host of a parasitic

0005- 



00006 millim. thick. 

 On stems. Observatory Bay.
