A Eevision of the TricMaeese. By G. Massee. 333 



minutely verruculose, elaters fusiform, spirals close, not prominent. 

 In some plants the elaters are simple, and often in other plants all 

 branched, the number of ends varying from three to ten. 



Eostafinski in his monograph represents a portion of an elater 

 belonging to the present species (fig. 222) as h&.Ymg JlaUened spirals, 

 which is not coiTect.

Trichia nitens, Fries, fig. 11. 



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

 bright yellow, smooth and shining ; mass of elaters and spores dull 

 orange ; elaters cylindrical, 14-16 yu, thick, rather short, ending in a 

 very short, abrupt, smooth apiculus, spirals rather prominent, distant, 

 not spinulose ; spores globose, ivarted, 14-16 /x diameter. 



(Specimen from Fries in Herb. Kew, and named by him " Trichia 

 nitens, Fr.") 



On wood. Upsala ! 



A very fine and distinct species, externally closely resembling 

 Oligonema nitens (Lib.), Efki., distinct from T. varia in the polished, 

 shining sporangia, and the thicker elaters with very short, abruptly 

 apiculate tips. 



Trichia varia, Eost., fig. 17. 



Sporangia scattered or aggregated, sessile on a broad base, tur- 

 binate, or subspherical and distinctly stipitate, smooth, yellow, dirty 

 ochraceous, sometimes tinged olive, stem when present, blackish ; mass 

 of capillitium and spores yellow ; elaters cijliadrical, 4—5 /^ thick, 

 spirals distant, prominent, more especially on the convex side when 

 the elaters are curved, tips smooth, tapering, straight or bent, 8-10 yw.
