A forma typica differt prœsertim pagina thalli infera nigrescente et adambitum tanlum 

 albicante atque rhizinis nigris. In Wright exsicc. n. 87, cortex superior 20 u lalus et 

 pseudoparencbymaticus, sed cellulac minores 2-3 p. latae et parietibus magis incrassatis 

 atque in parte externa zona amorpha 5-6 p. crassa. In cortice inferiore 20-30 u lato et 

 nigrescente, hyphae superficiel parallelae et oblique ramosae atque in parte externa pas- 

 sim subliberae seplataeque, lumine parvo et rotundo. Apothecia saepe in excipulo et in 

 margine sorediata. Caeterae nota? congruunt. 



Viget hœc species in Asia (Japonia, India et ins. Labuan) ; in Africa (Senegambia, ins. Borbonia, 

 Comor et Principis, atque saxicola in Socotra) ; in Ameiica utraque ; in Oceania (Polynesia). 



In Japonia, in ins. Nippon, in Aomori, n. 169, aprili 1897, legit R. P. Faurie, formam 

 hujus speciei forsan nomine proprio distinguendam, sed sterilem. Ejus laciniœ pleraeque 

 apice breviter ascendenti-recurvee et non semper sorediatœ ; caetera? passim granulato- 

 sorediata? ; subtus albidae atque rhizinis albescentibus, sat copiosis, non omnibus fulcran- 

 tibus, munitœ. Cortex superior pseudoparenchymaticus, cum cellulis 6-9 jjl latis, 

 20-30 alatus, sed passim inter stratumgonidiale interruptum usque ad medullam descen- 

 dens et tune 60-65 \l latus. Gonidia majora quam in forma genuina, 9-15 \l lata. Cortex 

 inferior a medulla vix distinctus ; in hoc hyphae solummodo strictiuscoadunatae.
