Canoparmelia Quintarigera
''Canoparmelia'' is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. ''Canoparmelia'', a segregate of the parmelioid lichen genus ''Pseudoparmelia'', was circumscribed by John Elix and Mason Hale in 1986. Description ''Canoparmelia'' lichens have grey or rarely yellow-green thalli containing the secondary chemicals atranorin and chloroatranorin, or rarely usnic acid, in the cortex. The thallus is made of more or less rotund lobes that are 3.0–5.0 mm wide and lack cilia; the medulla is white. The underside of the thallus is black or brown with naked brown margins and simple rhizines of the same colour. ''Canoparmelia'' produces small ellipsoid ascospores that measure 10–14 by 6–8 μm. The conidia are fusiform (spindle-shaped) or bifusiform, measuring 7–10 μm long.

John Alan Elix
John Alan (Jack) Elix (born 1941) emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology. Education His first degree, B.Sc., and his Ph.D were both in organic chemistry from the University of Adelaide. This was followed by post-doctoral years at the University of Cambridge and then a D.Sc. in natural products chemistry from the Australian National University. Career Elix spent a post doctoral year in 1966 at Cambridge, returning to Australia in 1967 to a lectureship in chemistry at the ANU. He retired as professor of chemistry in 2002, becoming professor emeritus. By 1975 he had already published several papers on the organic chemistry of lichens, and ultimately leading to work on the evolution, taxonomy and phylogeny of liche ...
