Leprocaulon gracilescens (Nyl.) I.M. Lamb & A. Ward
Nomenclatural data
J. Hattori Bot. Lab. 38: 523 (1974)
Stereocaulon gracilescens Nyl., Ann. Sci. Nat. Bot. ser. 4, 11: 210 (1859)
Morphology
Morphologically identical with L. albicans, for the description see under that species.
Chemistry
Contains atranorin and fatty acids. In Greenland, two chemotypes are recorded: (1) with atranorin and roccellic/angardianic acid (n = 1); (2) with atranorin and rangiformic acid (n = 1).
Remarks
This species may alternatively be considered a chemotype of L. albicans (Lamb & Ward 1974, Brodo et al. 2001) but proper nomenclatural change has not been proposed.
Ecology and distribution
