the elatcrs ; in the latter character it agrees with T. varia, but 

 differs in the spirals not being markedly more prominent on 

 the convex side of the bent elaters, the abrupt tips, and smaller 

 size of every part. The elaters are rarely more than 200 ^ 

 long. 



Trichia minima, Mass. 



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

 or irregular from mutual pressure, _2-^a/c ^^'rimrosc-ydlow ; mass 

 of elaters and spores same colour; elaters cylindrical, 5 — 7 \j. 

 thick, ending in smooth, tapering points about 8 — 10 ^i long, 

 spirals thin, rather distant, not prominent, without spines; 

 spores globose, very minutely warted, 10 ft diameter. 



Trichia minima, Mass., Rev. Trich., p. 836, fig. 18. 



On wood. Britain (Oldham). 



Sporangia o mm. diameter, forming dense clusters. Allied 

 to T. scahra, but distinct in the smaller size of every part, and 

 in the absence of spines on the spirals of the elaters. 



Trichia contorta, Rost. 



Plasmodiocarp creeping, fiexuous, suhronq^orsscd, umler or hay- 

 hrown ; mass of elaters and spores yellow ; elaters 2'5 — 3"5 /x, 

 cylindrical, tips usually stvollcn and terminated by a long, 

 slender spine; there is sometimes an interstitial swelling ; spirals 

 indistinct ; spores globose, minutely warted, 12 — 15 ju diameter.

I have seen no specimen of the present species, which is 

 said to have occurred in Britam. The cylindrico-compressed 

 flexuous plasmodiocarp of a dark brown colour, and the elaters 

 with long, spine-like tips and indistinct spirals mark the species. 

 The elaters appear to agree in structure with those of Trichia
