ON A NEW BRITISH SPECIES OF XYLOGRAPHA. 

 By the Rev. J. M, Cuombie, F.L.S., &c. 



Xylogxapha laxicicola, Nyl,, in Flora, 1875, i . 13. Thallns 

 effuse, very thin, greyisli-white, or scarcely any visible; apothecia 

 minute, superficial, oblong, or slightly flexuose, irregularly scattered, 

 at length somewhat explanate, with evanescent margin, black, in- 

 ternally whitish ; spores 8na3, ellipsoid, simple, colourless, 

 0.0012-15 mm. long, 0.007-8 mm. thick, apothecium brown, 

 paraphyses none, or not seen in a normal condition ; hymenial 

 gelatine tawny, wine-red with iodine. 



On the bark of larch trees, near the base. Ben Lawers, Crombie, 

 August, 1874. 



The above characters sufficiently distinguish the present species 

 from all the others of this genus. It probably derives its greatest 

 interest from being a purely corticole species, growing on the bark 

 of living trees, a habitat hitherto unknown for any other Xylo- 

 grapha, though, according to M. Fries, Scand II., p. 638, 

 X. parallela has been gathered corticole in Finland. The present 

 species was not met with but very sparingly on a single tree in 

 Lawers glen.
