Porpidia albocaerulescens (Wulf.) Hertel & Knoph var. polycarpiza (Vain.) Rambold & Hertel

Porpidia albocaerulescens is characterized by a whitish grey thallus and immersed apothecia with whitepruinose discs. The norstictic acid containing chemotype has a center of distribution in the subtropical and tropical regions of South-East Asia. It has been reported from the southern Mediterranean region, eastern North America, the tropical parts of eastern Australia ( Rambold 1989), the Philippines, India, China, Taiwan, Japan and Indonesia ( Hertel 1977). Therefore the finding in Thailand is not surprising. It is a further addition to the Thai lichen biota.
