Abstract

A new species and genus, Kalbionora palaeotropica, is described for a crustose lichen occurring in coastal forests in Thailand, Vietnam, and northeastern Australia. It is morphologically similar to Malmidea and Eugeniella, but differing in morphological and chemical characters. The single known species in the new genus contains atranorin, zeorin, the stictic acid chemosyndrome and chlorinated xanthones. Morphologically it is characterized by having asci of the Catillaria-type, a yellowish brown colour, a granulose epihymenium, dark brown hypothecium, hyaline, 1–3 transversely septate ascospores. Molecular data strongly support a phylogenetic position in Malmideaceae, sister to a clade including Malmidea, Savoronala and two species currently placed in Lecidea s. lat. (including L. cyrtidia and L. plebeja).
