Infrared Space Observatory 3 - 25 $\mu$m spectra of the R Coronae Borealisstars V854 Cen, R CrB, and RY Sgr are presented and discussed. Sharp emissionfeatures coincident in wavelengths with the well known Unidentified EmissionFeatures are present in the spectrum of V854 Cen but not of R CrB or RY Sgr.Since V854 Cen is not particularly H-poor and has a 1000 times more H than theother stars, the emission features are probably from a carrier containinghydrogen. There is a correspondence between the features and emission fromlaboratory samples of hydrogenated amorphous carbon. A search for C$_{60}$ inemission or absorption proved negative. Amorphous carbon particles account forthe broad emission features seen between 6 - 14 $\mu$m in the spectrum of eachstar.Comment: 11 pages with 2 tables and 4 figures in ApJ print page form.
