Recent results on charm fragmentation and hadron spectroscopy in e+/e- p collisions at HERA with the ZEUS and H1 detectors are presented. The measured fragmentation ratios and fragmentation fractions are in agreement with those measured in e+e-, thus supporting the assumption of universality. Measurements of the inclusive photoproduction of the neutral mesons η, ρ0, f0(980) and f2(1270) are also presented. At the same time results on production of pentaquarks are shown. Cross sections of observed states and upper limits on the production cross section of unobserved states are extracted in order to enable comparison between experiments.
