often assuming a black hue, as is the case with the specimens figured by 

 Bulliard. 



4. T. clavdta, Pers. (club-shaped Trichia) ; gregarious, peri- 

 dium obovate yellow shining even, stem rugose nearly of the 

 same colour, capillitium and sporidia ochraceous. Pers. Syn.

On rotten stumps. Not uncommon The lower part of the peri- 



c?m?/i, which has a shining, transparent skinny appearance, remains when 

 the sporidium and capillitium have vanished ; and in this state it resem- 

 bles a Craterium. This and the three foregoing species have more or 

 less the habit o^ Arcyria, splitting, though irregularly, all round. 



5. T. turhindta, With, {turbinate Tiichia) ; crowded, peridla 

 obovate sessile even tan-coloured, capillitium and sporidia 

 ochraceous. With. v. 4. p. 368. Soto. t. 85. Fr. Syst. 3Iyc,

On rotten wood. Common " Early in the morning whitish and 



resembling cream. At noon of the same day it becomes of a drier tex- 

 ture with an outward skin and is then yellow. The skin often begins 

 to separate and the seeds to ripen the same evening. If the sun shines 

 upon them they may happen to dry into a little horny substance." Sow. 

 I. c. The sporidia are not bright yellow, as in the following species. 



6. T. chrysosperma, Dec. (yellotv-seeded Trichia) ; crowded, 

 peridia rounded nearly sessile yellow inclining to cinnamon-red, 

 sporidia and capillitium ochraceous golden-yellow. Fr. Syst.

On rotten wood. Common. — The colour of peridium varies in 

 this and the foregoing species; the principal dependance is to be placed 

 in the sporidia. 



7. T. vdria, Pers. (variable Trichia) ; scattered, peridia 

 sessile subrotund or reniform at length yellow, capillitium and 

 sporidia ochraceous. Pers. Syn. p. 181. Fr. Syst. Myc. v. 3.

8. T. Serpula, Pers. (reticulated Trichia) ; peridia creeping 

 vein-like flexuous and reticulated yellow as well as the capilli- 

 tium and sporidia. Pers. Syn. p. 181. Fr. Si/st. 3Iyc. v. 3. p.

On rotten branches, leaves, &c. Not uncommon. — The peridium is 

 of a more or less bright yellow, and sometimes even bay ; the sporidia 

 and Jlocci of a golden yellow, even more bright than in T. chryso- 

 sperma. There are specimens of this species in Dr. Hooker*s Herba- 

 rium, from St. Vincents.
