Lepraria lobificans

	*Lepraria lobificans* Nyl.


	Nomenclatural data
	Flora 56: 196 (1873)
	Morphology
	Leprose, cottony, soft, usually thick, green to light grey; thallus margin diffuse, rarely delimited or with sublobes (not in Greenland material); medulla prominent, white; soredia loosely packed, variably sized, with medium to long projecting hyphae.
	Chemistry
	Atranorin, zeorin and the stictic acid complex.
	Remarks
	Large and prominent thalli are often common for this widely distributed species elsewhere in the world. In Greenland L. lobificans forms only small woolly patches, often in cracks and crevices between other lichens and mosses. Roccellic/angardianic acid was additionally detected in one specimen from Greenland which was morphologically very similar to L. lobificans. The fatty acids are normally not encountered in that species. The specimen with roccellic/angardianic acid is chemically identical with another recently described species L. santosii Argüello & A.Crespo (Crespo et al. 2006) which is morphologically distinct by the raised rim at the thallus margin and lobate, often subsquamulose growth form.
	Ecology and distribution
Greenland	On soil and bryophytes. L. lobificans has a western distribution in Greenland, being confined to the Low Arctic zone.
