The Boltzmann equation for the diffusion of Hawking radiation from microscopic black holes is solved using the test particle method. Formation of a dense cloud of interacting particles analogous to the photosphere of the Sun is confirmed. We find that at least two kinds of photospheres may form: a quark-gluon plasma for black holes of mass MBH ≃ 5 x 1014 g and an electron-positron-photon plasma for MBH ≃ 2 x 1012 g. The QCD photosphere extends from the black hole horizon for a distance of 0.2--4.0 fm for 109 g ≃ MBH ≃5 x 1014 g, at which point quarks and gluons with average energy of order ΛQCD hadronize. The QED photosphere starts at a distance of approximately 700 black hole radii and dissipates at about 400 fin, where the average energy of the emitted electrons, positrons and photons is inversely proportional to the black hole temperature. Possible consequences of these photospheres are discussed.
