X. FIMBRIARIA Nees. 



Carpocephalum pedunculate from the apex of the thallus 

 or its innovations, conic or hemispheric, concave beneath and 

 expanded at the margin into usually 4 large, pendent, campan- 

 ulate, 1-fruited involucres. Inner involucre oblong-oval or 

 subconic, protruding half its length beyond the involucre, with 

 the projecting portion cleft into 8-16 fringe-like segments 

 which are often more or less coherent at the apex. Calyptra 

 with a long style, fugacious. Capsule scarcely pedicelled, glo- 

 bose, irregularly circumscissile near the middle. Spores angu- 

 lar, slightly reticulate, apparently margined. Elaters rather 

 short, uni-quadrispiral. Antheridia immersed in the thallus, 

 without receptacle. Thallus thickened in the middle, with a 

 keeled costa, which in some species throws out lateral innova- 

 tions, usually conspicuously porose above, and with dark pur- 

 ple scales beneath. Gemmae wanting. Name from Lat. fim- 

 bria', a fringe. 

 * Pedundes more or less pilose; divisio?is of inner involucre 

 coherent at their apices. 

 f Inner involucre 8-cleft. 



1. F. elegans Spreng. Thallus 0.6 — 2.1 cm. long, 2 — 4 

 ram. wide, producing innovations from the costa underneath 

 and also from the apex, linear-oblong, the innovations obcord- 

 ate, emarginate or bilobed at the apex, glaucous-green and mod- 

 erately porose above, abruptly carinate and usually dark purple
