MNIUM. 35I 



an irregular network of lines ; plates of the outer surface of the 

 teeth only 2-4 times as wide as high ; transverse bars of inner 

 face less numerous (15-25) and more distant at the base of the 

 teeth. Synoicous. 



HAB. Bogs and marshes, rare. Fr. spring. 



This species, according to Amann, often grows intermixed with the foregoing, 

 and can hardly be separated from it without the inflorescence or the capsule with 

 peristome. 



79. OINOLIDIUM Swartz. 



A genus of mosses closely resembling certain species of 

 Mnium, such as M. punctatum, in habit and foliage. Capsule 

 similar, lid convex; peristome teeth short, obtuse, incurved; 

 inner peristome of 16 narrow-linear processes from a very 

 narrow basal membrane, supporting a dome-shaped cupola. 

 Spores large. ■ 



The peristome with its elegant dome-like membrane 

 supported on slender pillars, between which the obtuse outer 

 teeth curve inwards, forms the main character by which 

 Cinclidium is separated from Mnium. There are several other 

 species, all confined to northern latitudes. 



1. Cinclidium stygium Sw. (Tab. XLVIII. B.). 



Resembling the less luxuriant forms of Mnium punctatum ; 

 but always with a strong reddish tinge, often deep purplish 

 black, the young shoots only being green ; stems densely 

 interwoven with dark purple tomentum. Leaves rather small, 

 lower distant, upper crowded in a terminal rosette, rounded-ovate 

 or obovate, from a narrow base, obtuse with a short wide 

 apiculus ; when dry crisped and undulate. Border strong, red, 

 not thickened, of several rows of narrow cells, entire or 

 denticulate in the apiculus only ; nerve strong, red, reaching apex 

 and confluent with the border in the apiculus. Cells resembling 

 those of Mnium punctatum. Seta long ; capsule pendulous, 

 elliptic-oblong, rather wide-mouthed when empty; lid conical, 

 obtuse; peristome pale yellow, the inner orange. Synoicous. 



Hab. Deep bogs on mountains and moors, rare. Fr. summer. 



Although much resembling Mnium punctatum this interesting moss will readily 

 be distinguished by the characters italicised above. The peristome is a beautiful 

 object.
