In Asia : in China, prov. Yun-nan ramulicolam legit R. P. Delavay in sylvis circa 
fauces Yent-ze-hay, 8 augusti 1888 et prope fauces Hee-chan-men, 31 maii 1889. 
Thallus albido-glaucescens, parum expansus, 3-6 cent. latus (in exemplaribus corticolis 
15-20 cent. iatus), membranaceus, rigidus el opacus, K supra flavens, intus non reagens 
sed K (CaCl) leviter rubescens, laciniæ 15-20 mm. latæ, parum lobatæ, lobis ambitu 
rotundatis simulque sinuatis, ad peripheriam applanatæ ; in centro convexæ concavæque, 
marginibus passim crenalæ, ciliatæ ciliisO,5-2,5 mm. longis, nigris simplicibusque etomnino 
læves; intus albæ ; infra nigræ et rugosæ, parce rhizinosæ, rhizinis nigris parvisque, ad peri- 
pheriam brunneæ aut obscure brunneæ, nitidæ, late nudæ sed passim rhizinis 2-3,5 mm. 
longis, non fulcrantibus, aliquando sat confertis munitæ. In cortice superiore 18-20 y lato, 
fuscidulo, hyphæ superficiei perpendiculares, indistinctæ, etiam in lobis vetustioribus rete 
maculis parvis et inæqualibus formantes atque strato amorpho 4 & lato tectæ. Gonidia 
9-12 y lata. In medulla hyphæ 3-4 u crassæ. Cortex inferior 11-13 x latus, brunneus aut 
niger, superiori similis. Apothecia 0,5-20 mm. lata, breviter pedicellata, cupuliformia 
et demum applanata, raro perforata, excipulo primum lævi et dein subreticulatim rugoso, 
margine subcrenato, raro breviter ciliato et disco obscure rufo munita. In excipuli cortice 
40-50 y lato hyphæ rete maculis majoribus ac in cortice superiore formantes ; epithecium 
rufum ; hypothecium albidum ; paraphyses 2 & crassæ, articulatæ, ramosæ, ramis anas- 
tomosantibus, apice incrassatæ et 6-8 & metientes ; thecæ 70-80 p longæ et 38-48 y latæ, 
apice valde incrassatæ ; sporæ 26-28 y longæ et 14-16 y latæ, episporio 3-3,5 4 crasso. Gela- 
tina hymenialis fugaciter iodo cœrulescens, thecis persistenter tinctis. Spermatia cylin- 
drica recta, 6-7 & longa et 0,6-0,7 y lata; sterigmala 30-50 x longa, articulata, raro 
et breviter ramosa.

Variat thallo supra fuscidulo. Affinis ?. Yunnanæ, sed sæpe minor et aspectu alio, 
spermatiis minoribus atque sporis magis pachydermeis atque reactione recedens.
