nulls squamisque destituta aut raro parcissimo squamosa, cortice

Distributio geograpMca. Cosmopolitica fere est, at in re- 

 gione aequinoctiali raro observata ibique solum in montibus alti- 

 oribus provenire videtur, distributione autem adhuc defecte cog- 

 nita. In Europa passim — sat frequenter provenit, nee regio- 

 nibus maxime arcticis deesse videtur („f. admodum gracilis cae-
