On decayed wood. Appin. [United States.]

 times found T. varia with echinulate threads."— Cwrr. 



1189. Txichia serpula. P. "Eeticulated Trichia." 



Peridia creeping, vein-like, flexnons, and reticulated, yellow ; 

 capillitium and spores of the same colour. — Fr. S.M. iii. 29. 188.

 Trichia reticulata. Grev. ^.266. 



On rotten branches, leaves, &c. [United States.] 



Peridium more or less bright yellow, sometimes bay, spores and flocci of a 

 golden yellow, even more bright than in T. chrysosj)erma. — Eng.Fl. 



Threads very long, sometimes branched, sparsely echinulate, obtusely 

 pointed. 



1190. Trichia (?) flagellifer. B. d: Br. "Anomalous 



Trichia." 



Globose, sessile, metallic ; flocci flagelliferous at their tips ; 

 spores flesh-coloured. — B. ^ Br. Ann. N.H. (1866) no. 1143, t. 

 2,/ 4. 



On spruce fir. Dec. Badminton. 



Perfectly globose, but fixed only by a small portion of the surface, which 

 slightly projects, smooth, bay, reflecting metallic tints like a Physarum ; flocci 

 divided above two or three times. Spores CUUOS— '0004 in.) -OO/S— '01 m.m. 

 diameter. Perfectly distinct from every other Trichia by the colour of the 

 spores and metallic coat, in addition to the flagelliform threads. — B. d: Br. 



This is certainly not a good Trichia, as the threads are attached to, and 

 spring from, the inner surface of the peridium. It will more properly con- 

 Btitute the type of a distinct genus.
