forms of T, affinis would perhaps be deemed Trichia jackii 

 by some authors, as the spores do not nearly all show com- 

 plete reticulations. T, -proximclla^ Karsten, N. A. Fungi, No. 

 2690 undoubtedly belongs to this series. At least in our speci- 

 men the spores resemble those of varieties b and c above. 



All phases here are common in the fall, from September to 

 December, on decaying logs of every sort. 



25. Trichia scabra, Rostafinski. Plate IV. Figs. 4, 4« 



and 4^. 



Sporangia sessile, crowded, on a well developed hypothal- 

 lus, bright yellow. Elaters cylindrical, acute at the apex, 

 straight or scarcely curved; spiral bands, three or four cov- 

 ered with numerous short acute spinules, the intervals quite 

 wide and smooth. Spores minutely warted, .008-.011. 



Species not rare, occurring on fallen limbs, stumps, etc., 

 handsome. Easily recognized by the above characters, espec- 

 ially those pertaining to the elaters. The color is sometimes 

 rusty. The papillae which cover the spore show, when highly 

 magnified, a distinct net-like pattern, as described under T. 

 fallax; not at all rough, as hitherto described and sometimes 

 figured. September. 



26. Trichia, inconspicua, Rostafinski. Plate III, Figs. 5, 



5« and %b. 



Sporangia small, more or less spherical, collected in heaps 

 or scattered (discrete), brown, shining, inconspicuous, desti- 

 tute of hypothallus. Elaters cylindrical, extended at tip into 

 spines curved to one side and twice as long as the elater- 

 width, sometimes also inflated near the tip. Spiral bands 

 three or four, not conspicuous, with narrow intervals. Spores 

 delicately warted, .012-.013. 



Specimens have been referred to this species without com- 

 parison. The form is rare, but corresponds in all essential par-
