186 A Monograph of the Myxogastres. 



species, the question that naturally suggests itself is, has 

 Schroeter had the true species in view ? In Rostafinski's 

 Monograph, fig. 220, the spirals of the elaters are represented 

 as broad and fiat, no spines are shown in the figure. 



C. Spores with elongated, raised, fiat hmds not comhined to 

 fm^iii a netioorh. 



§ Bands not jntnctate. 

 Trichia Balfourii, Mass. 



Sporangia sessile, base broad or narrowed, crowded, hemi- 

 spherical or angular from mutual pressure, clear primrose-yellow ; 

 mass of elaters and spores deeper and duller yellow; elaters 

 cylindrical, 9 — 10 jx thick, sometimes swollen near the apex, 

 which is abrwptly narrowed into from 1 — 3 sliort, smooth spines, 

 generally more or less bent, spirals thin, not prominent, rather 

 distant, furnished with scattered, rudimentary sp)ines ; spores 

 globose, with a few broad, slightly raised, fiat lands, not punctate, 

 nor combined in a reticulate manner ; 16 — 18 ju. diameter. 



Trichia Balfourii, Mass., Rev. Trich., p. 339, fig. 4. 

 (Type in Herb., Kew.) 



On wood. Cape of Good Hope. 



Closely allied to T. JacJcii, but known by the absence of 

 punctiform markings on the raised bands of the spores. In 

 T. verrucosa the bands on the spores are much shorter and 

 more numerous, the elaters of the last-named species also differ 

 in the crowded spirals without spines and the simple stout 

 tips. 



Trichia sulphurea, Mass. 



Sporangia densely crowded, subdepressed, circular, angular, 

 or reniform in outline, pale yellow, smooth, mass of elaters and 

 spores pale lemon-yellow; elaters cylindrical, simple, or fre- 

 quently branched, especially near the tips, 9 — 10 /x thick, spirals 

 crotvded, not very prominent, tips not thickened, smooth, acute, 

 straight or slightly curved, 10 — 14 /u. long; spores globose, with 

 numerous short, slightly raised, straight or crescent-shaped fi,at 

 s, 10 — 14 iM diameter.
