Trichia. 187 



Trichia sulphurca, Mass., -Rev. Trich., p. 339, fig. 3. 

 (Type in Herb. Berk., Kew, n. 10906.) 



On wood. Ceylon. 



A very fine, large species with sporangia up to 1 mm. 

 diameter, forming densely crowded patches of considerable size. 

 Characterized by the thick cylindrical elaters with crowded 

 spirals, and the numerous short flat bands on the spores, which 

 look like warts under a low power. Most nearly allied to 

 T. nitens, but the spores of the latter have true rounded warts, 

 and the spirals on the elaters are further apart. 



Sands with minute depressions. 

 Trichia abrupta, Cooke. 



Sporangia densely gregarious, sessile on a broad base, hypo- 

 thallus firm, usually angular from mutual pressure, pale yellow ; 

 mass of elaters and spores orange ; elaters cylindrical, 7 9 /x 

 diameter, spirals rather distant, not prominent, with scattered, 

 rudimentary spinules, tips usually smooth and equal in thick- 

 ness to elater for a length of 8 10 p, then terminating abruptly 

 in two or three thin, straight or curved spines 8 10 /^ long; 

 spores globose, with numerous slightly raised, straight or curved 

 short lands of irregular width, furnished with minute, scattered 

 pits, 10 16- ju, diameter.

 (Type in Herb., Kew.) 



On wood. Britain (Ken Wood, Hampstead ; Kew, Carlisle) ; 

 United States. 



Allied to Trichia Jaclrii, but distinguished by the more 

 numerous and shorter bands on the spores and the different 

 elaters; separated also from T. intermedia by the numerous 

 hands on the spores not anastomosing, and by the absence of 

 thin ridges parallel to the long axis of the elaters.
