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 

 habit, easily distinguish this species from the last. Wilson

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



Sect. III. Leaves complanate ; stems procumbent. 



82. H. denticulatum, L. ; monoicous ; stem prostrate, 

 slightly branched, divisions erect; leaves complanate, inequi- 

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

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

In woods, on banks, etc., common. Bearing fruit in spring

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.
