BERNT LY.NGE. 



M.-N. Kl. 



Upper pseudocortex {30 — 160 u) with a thin brownish part at the 

 surface, otherwise uncoloured, hyphae thin-walled, but densely interlaced, 

 especially at the exterior part; many hyphae regularly growing out 

 to hairlike, undivided, furcate or even stellately branched, to 60 // long 

 emergences, forming the tomentum of the thallus. Gonidia glomerate, dis- 

 posed in a subcontinuous stratum under and in the pseudocortex, occasio- 

 nally in the whole medulla, more rarely in the cilia. Medulla white, hyphae 

 loosely interlaced, much branched. Lower pseudocortex like the upper 

 one in structure, well developed near the margin, poorly deve- 

 loped or wanting at the middle o f the laciniae; sometimes the two 

 cortices meet, excluding the medulla. 



Apothecia very numerous, pedicellate or subsessile, orbicular, to 8 mm. 

 in diam. Receptacle smooth, of the same colour as the thallus, minutely 

 tomentose (under a strong lens) Margin thick, persistent, incurvate, 



crenate or furnished with pointed or lacerate 

 lacinulae. Pseudocortex 40—210 // thick, 

 slightly darkened at the surface, otherwise 

 uncoloured; hyphae more or less parallel to 

 the surface and more densely interlaced at the 

 exterior part, otherwise of no definite direc- 

 tion ; many hyphae growing out as hair-like, 

 pellucid emergences. Gonidia glomerate, arran- 

 ged in an incontinuous stratum at the margin and within the pseudocortex, 

 wanting under the hypothecium. Disc plane, dark brown or brownish- 

 black, naked or with a thin white or caesious pruina. Hypothecium greyish 

 or uncoloured, 50 — Sou thick. Disc covered with a thin, broken, amor- 

 phous stratum. Hymenium 130—160« thick, at the exterior part brownish 

 or brownish-red, otherwise uncoloured. Paraphyses easily discrete, 0,8 — lu 

 thick, grown-out paraphyses slightly clavately incrassate and distinctly septate 

 at the apices, they are undivided or occasionally furcate, rarely branched 

 from the base. Asci narrowly clavate, 105 — 120// long, 34—37," thick, 

 octo- or rarely tetra-sporous. Spores obliquely biseriate, ellipsoidical or 

 fabiform, rounded at the ends and constricted at the septum, sometimes ot 

 an irregular form (one half less developed, apices protruded &c.|. Cell- 

 wall relatively thin, cell-room large, rounded, pore distinct in young spores, 

 indistinct or filled up in the old, opaque, dark brown or greyish black 

 spores. Size: 26,5 — 44,7," long, 13,2 — 24 /< thick. 



Pycnides frequent, occasionally immersed in low and broad papillae, 

 containing one or more pycnides. Pycnides globose, large, to 300 u in 

 diam. Perifulcrium black at the protrudent ostiolum, otherwise pale or
