ENDOSPOREiE. 
[CORNUVIA, 
differs in the inner sporangium-wall being furnished with de- 
pressed thickened lines, and breaking up, when mature, into 
quadrangular or pentagonal fragments. 
Hah. On dried roots of Rohinia. — Poland. 
This species is referred to in Hedwigia, 1887, p. 110,«by Raxjiborski, 
as being indistinguishable in the description from C. circumscissa ; the 
structure of the sporangium-wall suggests rather Perichcena populinci 
or P. depressa. 
3. C. anomala Karst., in Bidr. Kann. Finl. Nat. (1879), 
iv., p. 131. Sporangia scattered or gregarious, sessile, sub- 
globose, dirty ochraceous, shining, 1-5 mm. diam. Tubes of the 
capillitium 4 to 6 /x, diam., cylindrical, with numerous truncate, 
often clavate, free ends, provided with close-set, ring-shaped 
thickenings. Spores globose, smooth, dull ochre, or pale yellow, 
6 to 7 )u, diam. — Trichia anomala Karst., in Not. Sallsk. Faun. 
Flor. Fenn., ix., p. 354 (1868). 
Hab. On bark and wood of pine. — Finland. 
The numerous free ends and ring-shaped thickenings of the elaters 
and the smooth spores suggest that this is an irregular form of 
Trichia scabra. 
4. C. leocarpoides Speg., in Ann. Soc. Cient. Argent., xii., 
p. 256 (1881). Sporangia subglobose or pyriform, 0*6 to 0-8 mm. 
diam., yellowish-red or fulvous, not or scarcely shining, smooth ; 
the wall rather thick, subcartilaginous, soon evanescent above, 
often forming a persistent cup below. Stalk rigid, erect, brown 
or blackish, slender, smooth or subrugulose, hardly exceeding the 
diameter of the sporangium. Capillitium elastically protruding, 
adnate at the base, long persistent, tobacco-coloured or fulvous- 
ohve ; threads slender, 5 to 6 /x thick, forming a dense net with 
many terete, rounded-truncate free ends; spiral bands three or 
four, smooth, not papillose. Spores globose, smooth, filled with 
granules, fulvous-olivaceous, 8 to 10 /a diam. 
Hab. On rotten wood. — Apiahy, Brazil. 
This description applies well to a form of Hemitrichia clavata with 
many free ends to the capillitium.
