 sis it is a rare tiling to find an apotheciuni with many fertile asci, the latter 

 species also has moi'e easily discrete paraphyses, and the coloured external 

 part of the hymcniiim is broader and darker than in the former species. 

 Apothecia diam. 2 — 3 (usque 7) mm., \ulgr) numerosa, thallum inter- 

 clum totum tegentia. Discus primo concavus, dein subplanus vel varie un- 

 dulato-rugosus, castaneus, nitidus, epruinosus, margo te n u i s, i n tege r vel 

 crenulatus, receptacuUim pallide I'inereo-fuscescens, + plicato-rugosum. 

 Cortex reccptaculi marginem versus tenuis (13 — 15 [x), centrum versus cras- 

 sus (50 55 \J^, angusta parte exteriori obfuscatus, praeterea incoloratus; 

 hyphis sat distinctis, vakle pachydermaticis, formatus. Cortex interior 

 bene evolutus, crassus (50 — 65 p.), hyphae distinctae, subperpendiculares, 

 pachydermaticae. Gonidia sub cortice interiori numerosa, praeterea in tota 

 medulla tenui dispersa. Hypothecium levissime obscuratum, 18 — 25 |x altum, 

 hyphae subtangentiales. Hymenium angustum, 45 — 55 [j. altum, parte ex- 

 teriore late fusco-nigrescens vel obscure fuscescens, ceterum incoloratum, 

 Strato amorpho incolorato tectum. Paraphyses baud difficile 

 discretae (KOH), apice clavato-incrassatae et fusco-capitatae, distincte 

 constricte articulatae (KOH), indivisae. Sporae vulgo parce evolutae, 

 angustae limbatae, parvae, ellipsoideae 4 — 7 [x longae, 2,5 — 4 ;v. crassae.
