One species of Lasallia Mérat [L. pustulata (L.) Mérat] and 20 species of Umbilicaria were found in the Polish Tatra Mts. The Umbilicaria Hoffm. species were U. aprina Nyl., U. cinerascens (Arnold) Frey, U. cinereorufescens (Schaer.) Frey, U. crustulosa (Ach.) Frey, U. cylindrica (L.) Delise ex Duby, U. decussata (Vill.) Zahlbr., U. deusta (L.) Baumg., U. grisea Hoffm., U. hirsuta (Sw. ex Westr.) Hoffm., U. hyperborea (Ach.) Hoffm., U. laevis (Schaer.) Frey, U. leiocarpa DC., U. microphylla (Laurer) A. Massal., U. nylanderiana (Zahlbr.) H. Magn., U. polyphylla (L.) Baumg., U. polyrrhiza (L.) Ach., U. proboscidea (L.) Schrad., U. subglabra (Nyl.) Harm., U. torrefacta (Lightf.) Schrad. and U. vellea (L.) Hoffm. Umbilicaria aprina Nyl. was reported for the first from the Carpathians and U. subglabra (Nyl.) Harm. from the Polish Tatras. Umbilicaria arctica (Ach.) Nyl. was not confirmed from the Tatra Mts. A key to all taxa determination as well as detailed descriptions of their morphology and anatomy are supplied. The distribution and ecology of all species occurring in the Polish Tatra Mts are characterized by diagrams and maps.
