from a stout hypothallus, and also in the characters of the capillitmm 

 threads and spores. Plants 2-3 mm. high. Usually not more than 

 one complete polygon is present on a hemisphere of the spore. 



Trichia Kalhreyeri, Mass. (n. sp.), fig. 8. 



Sporangia crowded, sessile, often irregular from mutual pressure, 

 pale yellow, smooth; mass of capillitium and spores pale primrose- 

 yellow ; threads of capillitium cylindrical, 9-10 yu. thick, with short, 

 smooth, tapering ends, spirals not prominent, thin, close; spores 

 glohose, with raised narrow flat hands forming an irregular p'jlijgonal 

 network, 11-14 fj, diam. 



(Type in Herb. Kew.) 



On wood and living leaves. New Granada ! (W. Kalbreyer). 



Externally resembling Trichia chrysosperma, but readily distin- 

 guished by the absence of the ridges between the spirals on the 

 capillitium threads, and the narrow bands forming more numerous 

 polygons, from two to three complete ones being present on a hemi- 

 sphere of the spore. 



** Bands with minute depressions on the surface. 



Trichia affinis, De Bary, fig. 7. 



Sporangia sessile on a broad base, crowded, circular or elliptical, 

 often seated on a well-developed hypothallus, clear pale yellow ; mass 

 of elaters and spores pale yellow ; elaters cylindrical, 4-7 yu, thick, 

 ending in short, tapering, smooth tips, spirals thin, rather close, not 

 prominent, sometimes furnished with scattered rudimentary spinules ; 

 spores globose, with broad, slightly raised, flat bands combined into a 

 few irregular polygons, surface of hands with a central row of minute 

 pits, 10-14 jjb diameter.

Superficially resembling T. chrysosperma, from which it is known 

 by the row of pits on the raised bands of the spores. The bands are 

 united into very few polygons, rarely more than one being complete 

 on a hemisphere of the spore. Barely there is a free end to the band. 

 For distinctions from T. intermedia and T. superha, see under these 

 species. It is doubtful what species is intended in Sacc. Syll., as the 

 spirals of the elaters are said to form a network, and the punctae on 

 the bands are not mentioned.
