Obs. — In specimine archetypo a Gaudichaud lecto in Brasilia sporae 

 sunt omnino similes(l). — Cornparari possit Lecidea furfurosa Tuck., 

 cui thallus cinerascenti-granulosus tenuis, granulis minutis globulosis sub- 

 dispersis, hypothecio fusco vel nigricanti tenui impositis ; apothecia fusca 

 mediocria (latit. circiter 1 millim.) plana marginata, margine nigricante; 

 sporse 8 nœ incolores ellipsoideae simplices, longit. mm , 012-18, crassit. 



(I ) Observetur, primo in Bolivia lectam Lecideam hypomelam Nyl. , Lich. exot. , 

 p. 223, etiam obvenire ad cortices inCuba(ex hb. Tuck.) apotheciis obscuriori- 

 bus (fuscis vel fusco-rufescentibus, margine cinerascente), sporis paulio mino- 

 ribus (longit. mm ,04 8-2i, crassit. mu \0<10-l 4). Verisimiliter haud deest in 

 Nova Granata. Nec forte frustra ibiquairatur L. intermixla Nyl. late dislributa. 

 Huic proxima est Lecidea melaleuca Tuck. (scilicet arcte, sin nimis, accedens ad 

 ejus varietatem obscuriorem, Nyl.,Iic/i. Scandin.,p. 194), sed thallo albo tenui 

 granuloso-inaequali, apotheciis nigris marginatis, sporis oblongo-ellipsoideis 

 1-septatis, longit. mm ,0'18-23, crassit. nm ,007-8 ; ad corticem in Cuba, ex 

 hb. Tuckerman. — Lecidea polycampia Tuck. valde est affinis L. hypomelœ, nisi 

 ejusdem varietas, sporis paulio minoribus (longit. mm , 01 4-1 8, crassit. inin , 008- 

 mm ,010); apothecia lurida, margine cinereo-lurido, mediocria, hypothecio 

 crasso nigricante, paraphysibus fere mediocribus vel gracilescentibus, gelatina 

 hymenea iodo cœrulescente (dein thecis sordide violaceis). Etiam hsecce corti-
