Abstract
The genus Petroderma never been reported from the coast of Korea. In this
study, our collection from Chaeseokang is matched with P. maculiforme morphologically.
Petroderma maculiforme is characterized by having small irregular light to dark brown
crusts, a basal layer of irregularly shaped cells giving rise to erect parallel filaments
which easily separate with pressure, single chromatophore per cell, small spherical
to cylindrical unilocular sporangia in a terminal position, and plurilocular sporangia
narrower than erect filaments or wider and shorter than erect filaments in a terminal
position. In addition, Hineksia sordida was also collected from Korea. It is mostly
epiphytic and characterized by uniseriate filamentous thalli forming loose tangled
masses, sparse and spiral branching, some long lateral branches, rhizoids occurring
throughout the plant, plurilocular and unilocular sporangia scattered on separate
plants. Our molecular analyses based on the rbcL gene reveal that our samples of P.
maculiforme and H. sordida are nested within the clades of Petroderma and Hincksia,
respectively. Therefore P. maculiforme and H. sordida are reported as new records from
Korea based on morphological and molecular analyses
