nat. size, in moist and dry state; b, b, b, b, b, b, leaves K 30; c, basal 
areolation of a leaf < 260; d, point of the same x 260. 
Resembling the small forms of T. crispulum Bruch, but quite distinct 
by the leaves not being cucullate at apex.—I have found only some 
sterile stems of this little moss amongst a tuft of Hypnum cupressiforme.
