On stems of decaying trees, etc. Observed at present only 

 in Kent and Yorkshire. Bearing fruit in spring. 



Forming pale-green tufts. Stem prostrate ; branches and 

 branchlets proceeding from the rooting base, arched ; leaves 

 secund, directed upwards, lanceolate or oblongo-lanceolate, 

 strongly acuminate, obscurely if at all toothed; cells rather 

 loose ; fruitstalk an inch high ; sporangium cylindrical, slightly 

 arched, even; lid conical, obtuse. 



The longer leaves and sporangia, besides the difference of

 toothed, which comes very near to Schimper's description. 



Sect. III. Leaves complanate ; stems procumbent.

 slightly branched, divisions erect; leaves complanate, inequi- 

 lateral, ovate, apiculate, two-nerved; margin recurved; spo- 

 rangium oblong, incurved, cernuous ; lid conical, acute. — Hook.

Forming depressed, green, shining patches. Stem prostrate, 

 slightly divided ; branches and branchlets erect ; leaves flat- 

 tened, ovate or oblongo-ovate, inequilateral, attenuated up- 

 wards with a short apiculus, entire or slightly toothed above, 

 with two short nerves at the base ; margin recurved ; cells nar- 

 row, larger at the base; fruitstalk about an inch long, red- 

 dish, produced at the origin of the branches ; sporangium ob- 

 long, curved, cernuous ; lid conical, acute.
