CARPOMITRA INERMIS, Kutz. 



Gen. Char. Frond YmQ2iT, filiform, compressed or flat and midribbed, irre- 

 gularly branched. Fructification : mitriform receptacles terminating 

 the branches, composed of horizontal branching filaments whorled 

 round a vertical axis, and producing elliptic-oblong spores. — Carpo- 

 MiTRA [Kutz.), from Kaptro^, fruit, and /xirpa, a cap or mitre. 



Frons linearis, fiViformis, compressa v. plana, cosiata, vage ramosa. Fruct. : 1, 

 receptacula apice ramornm mitrcpformia, sporis paranematibusque undique ves- 

 tita. SporcB oblongce. 



Carfomitra. inermis; frond caulescent, alternately branched; branches long, 

 virgate, filiform, densely ramulous ; ramuli setaceous, long or short, 

 erecto-patent ; receptacles ovoid, ending the uppermost ramuli.

 Hab. Port Pairy and Port Phillip. In the Tamar, Tasmania. 

 Geogr. Distr. South coasts of New Holland. Tasmania. 

 Descr. Root tuberous, densely clothed with reddish-brown woolly fibres. Frond 

 1-2 feet high, dendroid or bushy. Steins one or several, densely clothed 

 near the base with brownish woolly filaments, and rough or spiny with the 

 remains of broken branches, undivided, closely set with alternate branches 

 in the upper half. Branches 6-1 2 inches long or more, virgate, once or 

 twice compound, the primary and secondary divisions more or less copiously 

 fin-nished with erecto-patent ramuli. Ramuli bristle-like, long or short, 

 few or copious, straight, subacute. Fructification not perfectly known ; se- 

 veral of my specimens produce ovoid or conical, swollen, gland-like bodies 

 (receptacles ?) at the ends of the upper ramuli, but in none of them have I 

 succeeded in finding spores. The substance is very rigid, quite wiry when 

 dried. The crAour is a clear brownish-olive, becoming very dark or black- 

 ish in the herbarium.
