Obs. — Thallo, apotheciis convexis, epithecio, et sporis minus septatis 

 difïert a L. endoleuca var. Laurocerasi (Del. in Dub. Bot. GalL, p. 653), 

 pro qua eam olim habui (Flora, 186/j, p. 620), atque rêvera L. propo- 

 sita si stère possit varietatem L. endoleucœ. Nomen « atrogrisea » Del. 

 accipere non potui, nam in herbario Deliseano mdoleucam invenimus 

 nominatam « L. enteroleneam Acb. », « L. enteroleucam var. abietinam 

 Del. », etc., et illud nomen nihil certi spectat; contra nomini endoleuca,' 

 jam 1853 (in Bot. Notiser, p. 98) sensum fixum dedi. — L. endoleuca 

 etiam prope Chiquinquira, corticola, altit. 2700 metr. obvenit (Lindig,
