 thallo KOH non reagente ab hac specie differunt. 



Ad folia arborum. St. Ann's Valley (No. 56). La Seiva Valley 

 (No. 60). Supra thallum parce etiam observavi Cyphellam (conf.

 stramineo-glaucescens, sat opacus, KOH flavescens, hypothallo indis- 

 tincto. Apothecia lat. 0.5-0.4 mm., dispersa aut subaggregata, 

 basi constricta, disco piano, pallido, pruinoso, margine sat tenui, 

 haud aut leviter prominente, parum verruculoso, stramineo-albido, 

 opaco, persistente. Hypothecium rufeseens. Hymenium circ. 0.0S0 

 mm. crassum, totum decoloratum aut epithecio pallido, jodo persist- 

 enter caerulescens. Paraphyses ramoso-connexae. Sporae singulae, 

 decoloratae, demum pallidae, oblongae, apicibus rotundatis, murali- 

 divisae, cellulis numerosissimis, long. 0.05 6-0. 060 (-0.030), crass. 0.018 

 (-0.012) mm. Conidangia (pycnidia) prominentia, depresso-sub- 

 globosa, albida. Conidia (stylosporae) decolorata, ovoideo-oblonga, 

 altero apice rotundato, altero obtuso, recta, simplicia, long. 0.007, 

 crass. 0.002 mm. Gonidia globosa, diam. 0.006-0.008 mm., tantum 

 simplicia visa, membrana tenui, forsan pleurococcoidea. 



Sporopodium glaucophacodcs (Nyl. Lich. Guin. p. 19) sporis majori- 

 bus margine apotheciorum laevigata et disco carneo-fuscescente, haud 

 pruinoso ab hac specie differt. 



Ad folia arboris. Maraval Valley (No. 70). 



16. Lecidea coronulans (Nyl.) Vain. {Lecanora granifera var. 

 coronulans Nyl. in Fl. 1874, p. 72), var. Gaspareina Vain. (var. n.) 

 Sporis subglobosis aut breviter ellipsoideis, long. 0.00S-0.011, crass. 

 0.005-0.007 mm. a Lcc. coronulanie (Nyl.) differt. Apothecia disco 

 cinereo fuscescente aut fusconigro, margine verruculoso, verruculis 

 albidis, gonidia continentibus, ceterum perithecium intus fuscofuli- 

 gineum, hyphis conglutinatis. Hypothecium fuscofuligineum, hyphis 

 conglutinatis. Thallus albidus aut albido-glaucescens, verruculis 

 minutis, intus albis inspersus, KOH flavescens, verruculis fulvescen- 

 tibus (in No. 44 reactio minus distincta). 



Ad hanc speciem non pertinet Lecanora coronulans Nyl. (Fl. 1876, 

 p. 510). 



Ad corticem arborum. Maraval Valley (No. 44). Gasparee 

 Island (No. 38).
