A survey of thelotremoid lichens (Ascomycota: Ostropales) in subantarctic regions excluding Tasmania.

Thelotremoid lichens (Ostropales, Ascomycota) with a trentepohlioid photobiont in Tierra del Fuego, the Falkland Islands, the South Island of New Zealand, and subpolar islands of the southern Hemisphere are studied. Twenty-five species are accepted, with three species described as new to science: Melanotopelia blepharostoma Lumbsch & Divakar, Topeliopsis athallina Lumbsch & Mangold and Topeliopsis patagonica Mangold & Lumbsch. The new combination Topeliopsis novaezelandiae (Szatala) Lumbsch & Mangold is proposed. [ABSTRACT FROM AUTHOR]
