In a study from eight Slovenian show caves: Črna jama, Kostanjeviška jama, Krška jama, Pekel pri Zalogu, Pivka jama, Postojnska jama, Škocjanske jame, Županova jama and two mines, Idrija mer­cury mine and Mežica lead and zinc mine, equipped for tourist visits, 37 taxa of Bryophyta and Pteridophyta were identified. The most frequent organisms were mosses <em>Amblystegium ser­pens, </em>B<em>rachythecium </em>sp., <em>Eucladium verticillatum </em>and <em>Fissidens taxifolius</em>. The highest diversity of bryophytes was recorded in Mežica mine with16 identified taxa where lamps are on con­tinuously. Bryophytes were collected at wide range of photo­synthetic photon flux densities (PPFD) from 0.2 to 530.0 μmol photons/m</span><span class="A10" style="font-family: ’Minion Pro’;"><span style="font-size: 5pt;">2</span></span><span style="color: black; font-size: 9pt; mso-bidi-font-family: "Minion Pro";">/s. <em>Eucladium verticillatum </em>had the highest span of PPFDs, ranging from 1.4 to 530.0 μmol photons/m</span><span class="A10" style="font-family: ’Minion Pro’;"><span style="font-size: 5pt;">2</span></span><span style="color: black; font-size: 9pt; mso-bidi-font-family: "Minion Pro";">/s.
