Dorcadion speciosum Lindb. Muse, scand. 28 (1879). 



Autoicous ; tufts loose, more or less dense, yellow-green, fuscous at 



base, the stems branched, i — ij in. high. Leaves laxly imbricated 



when dry, patulous or slightly recurved when moist, oblong-lanceolate, 



more or less longly acuminate, acute, all margin revolute, nerve nearly 



reaching apex ; cells at base elongato-rectang., with unequally incrassate 



walls, gradually passing upward into rounded strongly incrassate cells with 



one or more simple or bifid papillae. Caps, emersed or emergent, 



leptodermous, faintly narrowed below the mouth, passing gradually into 



the pedicel by a longish neck, cylindric or rarely oval-oblong when dry, 



smooth, greenish, afterwards pale yellow, more or less furrowed ; stomata 



superficial ; bands 8, faint or at most marked by a short row of large 



quadrangular longitudinal cells ; teeth 8 bigeminate, rarely cleft in 



median line, pale, densely papillose, opake, revolute, with the upper part 



applied to capsule wall, cilia 8 white, large papillose, sinuose at margin. 



Lid conic with red border. Cal. conic-campanulate, blackish at apex, 



covering all caps., and with yellow hairs. Male infl. axillar, gemmiform, 



the bracts ovate, acuminate. 



Hab. — Trees in alpine districts, not common. Fr. 7 — 8.

Larger than 0. affine, with less dense leaves, the capsule longer and 

 cylindraceous, pale yellow, the bands indistinct ; the branches also are 

 longer, and the seta is variable in length, but the capsule is always more 

 exserted than in 0. affine, the bands being most evident after sporing ; the 

 leaves are frequently of a reddish-brown colour with areolation varying in 

 density.
