Stromate corticali, cra,sso, ramuli dimidlam partem ambiente, extus fusco-
nigro, intus subfusco, ex filamentis mycelicis dense contextis formato, in partes
polygonales fracto, 6 cm. circa longo, 2 cm. lato, 2-3 mm. crasso; peritheciis
cortice immersis, sparsis vel subgregariis, erectis, in collum longum cy lindraceum,
crassum productis, ostiolis stngule peridermium perforantibus,
conoideo-obtusis, prominentibus; ascis clavatis, valde evanidis et vix visibi-
libus, polysporis (?); sporidiis allantoideis, curvulis, pallide umbrinis, 5-6 » 2'/,.
Si asci vere polyspori sint, dubium est, nam nimis evanidi et vix visibiles
sunt. Si asci octospori, ut sporidia saepe in libértate in acervulos octonos
collecta demonstrare videntur, aptius species haec, propter etiam stromatis
naturam, in genus Eulypa transferenda est, ubi speciebus nonnullis {E. spinosa
etc.) afpnis videtur.
