  Infrared Space Observatory 3 - 25 $\mu$m spectra of the R Coronae Borealis
stars V854 Cen, R CrB, and RY Sgr are presented and discussed. Sharp emission
features coincident in wavelengths with the well known Unidentified Emission
Features 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 the
other stars, the emission features are probably from a carrier containing
hydrogen. There is a correspondence between the features and emission from
laboratory samples of hydrogenated amorphous carbon. A search for C$_{60}$ in
emission or absorption proved negative. Amorphous carbon particles account for
the broad emission features seen between 6 - 14 $\mu$m in the spectrum of each
star.
