Cenomyce acuta Tayl., New Lich. Herb. Hook. (1847) p. 186, 

 his verbis descripta est: „Thallo foliaceo, minuto, crenulato; po- 

 detiis subulatis, brevibus, ramosis, teretibus, fusco-cinereis, sub- 

 pellucidis; gemmis confertis rufescenti-albidis. Hab. Islands of the 

 Pacific; Hook. herb. — Tufts dusky brown, rigid, scarcely 1 inch 

 high. The buds may be observed expanding into minute crenu- 

 late scales at the bases of the podetia; these resemble in colour 

 and semitransparency shreds of glue: they are much acuminated 

 and tipped with black. Allied to C. pityrea b. acuminata Ach., 

 differing essentially by the subpellucid and brown podetia." — ■ 

 Observante Nyl. in Syn. Lich. (1858—60) p. 196 not. esset „C1. 

 fimbriata minor cornutiformis, podetiis decorticatis subhyalinis". 

 In Fl. 1888 p. 19 n. 1224 a Miill. Arg. nominatur CI. squamosa 

 var. acuta, „quae habitu etiam ad CI. fimbriatam var. adspersam 

 Tuck, valde accedit, at validior (semipoUicaris et humihor), hinc 

 inde lacerato-hians et podetiorum apices baud nudati vel sal- 

 tem non farinulenti, magis cartilaginei, subulato-acuuiinati, recti 

 et subdeflexi, baud raro confertim acute ramuligeri" (ex specim. 

 orig., teste Mull. Arg.). Ob annotationes meas mancas cerium 

 judicium de hac planta melius est in posterum differre. Ad 

 Cenomycetes clausas ochro- vel phaeocarpas tamen pertineat.
