Sporophyte a dark brown oval capsule 0.7-0-8 mm. long, on a 

 short seta 0.5-2 cm. high ; spores 6-8 p. in diameter, nearly 

 spherical, dark brown; elaters 250 long, wider than the spores, 

 bispiral. 



A very common species on rotten wood distributed from the 

 mountain region of Georgia to Wisconsin and northeastward; 

 also European. 



It has been distributed by Sullivant : Muse. Alleg. 242 (as 

 Jungermajinia cmvifolid); Austin : Hep. Bor.-Am. 60 ; and in Hep. 

 Amer. 17. Several figures exist; of these. Hooker, Brit. Jung. //. 

 I J, and Suppl. //. /, and Ekart, Syn. Hep. Germ. //. 8.f. jp, are 

 among the best ; that in Smith, Eng. Bot. //. ijo^ poorly repre- 

 sents the plant.

Gametophyte a slender creeping, usually pale green leafy stem; 

 leaves often wider than long, decurrent, slightly imbricate, bifid 

 one third their length with an obtuse or rarely lunate sinus and 

 acute connivent segments; leaf-cells mostly uniform, 36-40 // in 

 diameter: dioicous ; perianth on a very short branch, linear-fusi- 

 form, fleshy, formed of three layers of cells at base and two above ; 

 antheridia usually near the apex of a branch. Sporophyte a 

 short-stalked, oblong-cylindric capsule enclosed at first in a fleshy 

 calyptra formed of three layers of cells; spores cinnamon-colored. 



One of our most common species growing in large patches on 

 decaying logs and rarely on the ground from Florida to Virginia, 

 California and generally distributed over the northern portion of 

 America ; also European. The species was long confused with 

 C. connivcns (Dicks.) both in this country and in Europe. During 

 this period it was distributed under the original name of Junger- 

 inannia connivens by Sullivant. Muse. Alleg. 246, and as CepJialo- 

 zia cofinivens by Austin, Hep. Bor.-Am. 57. Lindberg, thinking 

 that this species was the true C. connivens, gave to that species the 

 name of C. viultiflora. Later, Spruce, identifying the true C. con- 

 nivens, unfortunately gave the same name {C. inultiflom) to the 

 present species. Under this name the species was distributed by
