Studies in the lichen family Pannariaceae VIII. Seven new parmelielloid lichens from New Zealand

Abstract

Seven new lichen species are described, two from alpine/subalpine habitats (Parmeliella crassa and Santessoniella brunnea), three from dark and humid lowland bush‐vegetation (Fuscopannaria granulans, Pannaria delicata, and Parmeliella subtilis), one from open, but moist mountain forests (Fuscoderma pyxinoides), and one from lowland valleys (Parmeliella aggregata). The delimitation of the parmelielloid genera is discussed and a key is given to distinguish them. An emended key to the sorediate species of Fuscoderma is also included, as well as one to the genus Fuscopannaria in New Zealand and Australia. Several species are transferred to this genus: Fuscopannaria crus tata (from Pannaria), Fuscopannaria decipiens (from Pannaria), Fuscopannaria minor (from Parmeliella), and Fuscopannaria subimmixta (from Pannaria). F. minor is identical with material which has been mistakenly called Pannaria fuegensis in South America, the type of which clearly belongs in Psoroma; the necessary transfer to that genus is done here.
