Parmotrema adspersum

Parmotrema adspersum is a species of lichen in the family Parmeliaceae. It was originally described as a species of "Parmelia" by Edvard August Vainio in 1907. John Elix transferred it to "Parmotrema" in 2002, reasoning that its thick-walled ascospores (measuring 16–18 by 6–8 μm) are typical of that genus. "Parmotrema adspersum" is common in Thailand and the Philippines.
