A Bevision of the Trichiacese. By G. Massee. 337 



Tricliia reniformis, Peck. 



Sporangia gregarious or clustered, sessile, suhglohose or reniform, 

 small, brown ; flocci few, short, sparingly branched ; spores globose, 

 minutely echinidate, yellow-ochre, sometime !S tinged with green, 

 •0005 in. in diameter (.— 12-13 /x).

 p. 76; Sacc, SylL, n. 1510. 



Owing to the scanty information respecting the elaters, the 

 affinities of the present species are doubtful ; may possibly be allied to 

 Trichia inconspicua. 



Trichia contort a, Eost. 



Plasmodiocarp creeping, jiexuous, siibcompressed, umher or hay- 

 brown ; mass of elaters and spores yellow ; elaters 2 • 5-3 • 5 /*, 

 cylindrical, tips usually swollen and terminated by a long slender 

 spine, there is sometimes an interstitial swelling ; spirals indistinct ; 

 spores globose, minutely warted, 12-15 yu, diameter.

On rotten wood. Britain ; Germany ; France ; Denmark ; 

 Sweden ; Australia. 



The peculiar cylindrico-compressed, flexuous plasmodiocarp of a 

 dark brown colour, and the elaters with long spine-like tips and 

 indistinct spirals mark the present species.

 Trichia scabra, Eost., fig. 13. 



Sporangia rarely scattered, typically gregarious, sessile on a broad 

 base, seated on a hypothallus, circular or polygonal from mutual 

 pressure, varying from yellow through orange to pale brown ; mass 

 of elaters and spores orange ; elaters cylindrical, 6-8 /x, thick, ending 

 in smooth, acute, straight or slightly bent tips 7-10 fi long, spirals 

 not very prominent, rather distant, bearing numerous short acute 

 spines ; spores globose, epispore warted, warts rather large, numerous, 

 8-12 fju diameter.
