strato 80 y lalo et in ima parte passim subliberæ. Apothecia ignota. 
In specimine in ins. Taili a Vesco anno 1847 lecto cilia similiter nigra et elongata, sed 
breviter ramosa, ramis tenuibus, ideoque notis anatomicis cum hypoleuca omnino 
convenientibus, hæc dendrilica ab ïilla specifice separari posse non videtur. Jam lecta

Inter exemplaria satis numerosa a fr. Rodriguez in ins. Borbonia lecta, quædam 
laciniarum margines vel passim coralloideos seu microphyllino-dissectos (eadem forma 
laciniis lateraliter in centro speeiminis aut centrum versus microphyllino dissectis lecta 
fuit in Japonia a R. P. Faurie in Togakuski, n. 784 pr. p., 16 septembris 1898), vel simul 
sorediatos isidiatosque præbent. Alia formam distinguendam fortasse exprimunt. In ea 
laciniæ 1-1,5 mm. latæ, dichotome aut trichotome ramosæ, ramulis raro subimbricalis, 
sæpius discretis et tunc sub pulvinulo a rhizinis formato reponentibus; supra cineras- 
centi-albidæ, passim nigræ aut nigro-variegalæ (an morbose ?), laleraliter ciliis raro 
simplicibus sæpius ramosis ciliatæ ; subtus lateraliter cortice superiore recurvo corticatæ, 
in medio late cortice denudatæ, albidæ vel nigrescentes atque araneosæ, etrhizinis multum 
numerosis et ramosis munitæ. In cortice 70-80 y lato, albido etextusflavido et corpusculis 
repleto,hyphæ superficieiparallelæ ramosæque etinzonaflavidaramos verticales anastomo- 
santesque emittentes; gonidia10-12y latainstrato crasso et continuo sub corticesuperioreet 
sub cortice subtus lateraliter curvato ; hyphæ gonidiales laxe implexæ et dein stratum sat 
densum, 120-140 x latum, formantes et in ima parte sæpe nigrescentes et passimsubliberæ. 
Apothecia 1,5-3,5 mm. lata, cupuliformia, supra lacinias subpedicellata, excipulo lævi, 
margine primum integro et demum vix crenulato atque disco obscure fusco ornata. 
In excipuli cortice 80-120 y lato et albido hyphæ verticales et ramosæ, atque in zona 
exteriore, obscurius colorato, strictius coadunatæ cum ramis anastomosantibus ; gonidia 
sub cortice et sub hypothecio albido; epithecium rufescens et granulosum; paraphyses 
130 y altæ, 1 u crassæ, ramosæ, ramis increbre anastomosantibus, apice paulum incras-
