Hypotrachyna paraphyscioides is a species of foliose lichen in the family Parmeliaceae.[2] Described in 2011 from a single specimen collected in Colombia's Sierra Nevada de Santa Marta at nearly 2,900 metres elevation, this lichen is distinguished by its unusual forked marginal hairs and complete lack of attachment structures on its underside. It forms loose, rosette-shaped colonies on tree bark and is known only from its original discovery site in montane forest.
Hypotrachyna paraphyscioides was described in 2009 by Harrie Sipman from a single collection made on the northern slope of the Sierra Nevada de Santa Marta, Colombia, at 2,880 m elevation. Its epithet reflects the close external resemblance to H. physcioides: both share narrow, grey lobes and the same medullary chemistry. Molecular data were not available, but morphologically the new species is set apart by two striking features—forked marginal cilia and the complete absence of rhizines on the lower surface. These characters, together with a suite of barbatic acid derivatives in the medulla, distinguish H. paraphyscioides from all other described members of the genus.[3]
