Trichia. 187 



Trichia sulphnrca, Mass., Rev. Trich., p. 330, 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. 



§ Bands with minute dejjrcssions. 

 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 ju., then terminating ahra^My 

 in tioo or three tldn, straight or curved sjnncs 8 — 10 /x long; 

 sjwres globose, toith numerous slightly raised, straight or c^irvcd 

 short lands of irregidar width, furnished with miivute, scattered 

 flits, 10 — 16 /x diameter.

 (Type in Herb., Kew.) 



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

 United States, 



Allied to Trichia Jachii, but distinguished by the more 

 numerous and shorter bands on the spores and the different 

 elaters; separated also from T. intermedia by tlie numerous 

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

 thin ridges parallel to the long axis of the elaters.
