Trichia. 189 



The spores somewhat resemble those of Trichia Jackii, Host., 

 but are smaller ; the raised bands are narrower and anastomose 

 irregularly, and the minute depressions more constantly arranged 

 in a single row. Agreeing with Trichia chrysospcrma, Host., in 

 having the spirals on the elaters connected by ridges, but at 

 once distinguished by the bands on the spores being furnished 

 with minute depressions. I was at one time led to believe, 

 from examination of a specimen supposed to be authentic, 

 communicated by Mr. H. Wingate, of Philadelphia, who received 

 it from the author, that the present species was synonymous 

 with Trichia proximella, Karst., but a second authentic speci- 

 men of the last-named species agrees with the characters given 

 by Karsten, hence T. intermedia will remain as a distinct species. 



Var. persimilis, elaters very much and irregularly branched, 

 Ranches usually short, and as thick as the elaters; rest as in 

 typical form.

 Fenn., Forh., 1868, ix., p. 353; Karst., Myx. Fenn., p. 139;

An authentic specimen from the author proves the present 

 form to be a variety, or more probably an abnormal form, of 

 the present species. 



D. Spwes with raised flat bands combined to form a network. 



* Sands plain. 

 Trichia chrysosperma, Rost. 



Sporangia crowded or scattered, sessile, base broad or narrow, 

 yellow or ochraceous cinnamon; mass of elaters and spores 

 bright primrose-yellow; elaters cylindrical, 5 7 /x thick, tips 

 short, smooth, straight or curved, spirals not very prominent, 

 rather distant, sometimes with a few scattered spinules, con- 

 nected by thin ridges running parallel to the long axis of the 

 elater; spores globose, with deep, narrow raised bands combined 

 to form an irregular polygonal network; surface of bands not 

 punctate, 12 14 /* diameter.
