Admiralty Islands. — On thin bark of trees: sparingly gathered. (Spores - 016- 

 0-022 millim. long, 0'006-0-007 millim. thick.) 



This species was founded on Bermudan specimens collected by Mr Moseley, and these 

 two distant localities are the only ones hitherto recorded for it.

 flexuosa, intus albida ; sporse 8-nse aciculari-fusiformes 7-9 septatse, longit. 0'030-0 - 035 

 millim., crassit. - 004 millim., paraphyses irregulares graciles, hypothecium incolor. Iodo 

 gelatina hj^meuialis dilute vinose rubescens. 



Species apotheciis elongatis thallino-obductis (epithecio solo nudo) bene distincta, facie 

 fere Graphidis pavonianw. Spermatia arcuata, longit. 0'018-0 - 023 millim., crassit. - 0005 

 millim. 



Admiralty Islands. — On the bark of trees ; probably not uncommon.

Graphis dendrogramma, Nyl. ex Crombie in Journ. Linn. Soc. Lond., xvi. p. 226. 



Affinis Graphidi settee, sed apothecia csesio-pruinosa longiora dendroideo-divisa, thal-

 millim. 



Admiralty Islands. — On the bark of trees ; very sparingly gathered. 



Verrucaria paramera, Nyl. 



Verrucaria paramera, Nyl. ex Crombie in Journ. Linn. Soc. Lond., xvi. p. 227. 



Thallus macula luteo-pallescente indicatus ; apothecia pyrenio integre nigro, parte 

 dimidia superiore nuda convexa prominula (latit. 0-5-07 millim.) ; sporse 8-nse, fuscas vel 

 fuscescentes, ellipsoidese vel oblongo-ellipsoidea;, 6-loculares vel demum loculis quibusdam
