glutinatis formata, gonidia protococcoidea, ca. 10 a diam. stratum continuum 
ca. 40 u lat. formantia ; medulla ea. 150 u lat. ex hyphis ca. 2-3 p lat. intricatis

paraphyses tenues, non bene discrete septate, sursum nigro-brunneæ, 70u alt. ; 
asci clavati, 55-65 ax 15 p ; spore ellipsoideæ, hyaline, 12-14 u x 5-7 a. 
Ad saxum ferrugineum pulverescens. Mont Dore, May. On serpentine

L. Comproni A. L. Sm., sp. nov. 
Thallus tenuis, determinatus, stratum continuum formans, superficie minute 
plicatus vel granulatus, flavo-ochraceus. Apothecta prominentia, 05-1 mm. 
lat., novella disco plano flavo-ochraceo, margine integro nigro parum elevato

The thallus forms a thin layer over the inequalities of the bark; it 
resembles somewhat an Australian species, L. ludibunda Müll.-Arg. (Lich. 
Beitr. n. 1162 in Flora, Ixx. 321, 1887).
