Thailus large, up to 20 cm. in diam., loosely affixed to the substratum, 

 rather firm, but fragile. Laciniae discrete at the circumference, otherwise 

 densely contiguous or imbricate, or even interlaced and congested. Laci- 

 niae parallel to the substratum or towards the centre slightly ascendant, 

 stellate, narrow, 0,5 — i (2) mm. broad, linear, elongate, multifid, repeatedly 

 furcate, or short, unbranehed to almost papillaceous. Laciniae more or less 

 convex, flattened at the circumference of the thalius, with regular contours 

 and minutely rugulose or even surface, epruinose or rarely slightly bluish 

 pruinose. Secondary laciniae well developed, short, narrowly fixed, 

 unbranehed, papillaceous or digitately incise, towards the centre occasio- 

 nally covering the whole thalius, giving it a microphylline appearance. 

 I'hallus opaque, rarely with a faint lustre, colour chestnut brown or 

 greyish brown, at the circumference paler, wetted with a strong 

 tinge of green. (Morbid plants discoloured, greyish or greyish-white, 

 old herbarium specimens often intensely castaneous). Lower side un- 

 coloured or greyish- white or yellow at the circumference, otherwise brownish 

 black or black. Rhizinae scattered, black, unbranehed or furcate, 

 80 — 95 u thick. 



Thalius covered with a thin, amorphous stratum. Gonidia glomerate, 

 disposed in an incontinuous irregular stratum, 180 — 190/« thick, sometimes
