The following analysis of the results of the examination of a large 
number of specimens of Trichia^ obtained from widely separated local¬ 
ities by personal collection or from correspondents, shows some interest¬ 
ing and unexpected facts, and permits conclusions to be drawn which 
may necessitate a revising of specific lines. By far the larger number of 
specimens examined were, undoubtedly. Tv. chrysosperma, Bull., and as 
they, with two exceptions, dilfer in no respect from the typical descrip¬ 
tion, I have omitted them from the list: 
1. West Fairmount Park, Philadelphia, Pa. Spores distinctly of 
the Tr. Jackii type with bands pitted, irregularly branched and zigzag in 
outline; elaters spinulose, 4.5 mic. m. wide; interspiral ridges present, 
but few in number, irregular and indistinct. 
2. Fairmount Park, Philadelphia, Pa. Spores of the Tr. Jackii 
type ; elaters spinulose, 4.5 mic. m. wide; interspiral ridges present and 
distinct. 
3. Fairmount Park, Philadelphia, Pa. Spores of the Tr. Jackii 
type; elaters very spinulose, 4.5 mic. m. wide ; interspiral ridges present 
and very distinct. 
4. Fairmount Park, Philadelphia, Pa. Spores of the Tr. affinis 
type principally, with a small proportion of Tr. Jackii spores; elaters 
spinulose with short spines, 4.5 mic. m. wide; interspiral ridges pres¬ 
ent, but not all parallel to axis of elater, some connecting with the ad¬ 
jacent spirals at acute angles. 
5. Fairmount Park, Philadelphia, Pa. Spores of the Tr. Jackii 
type ; elaters spinulose, 4.5 mic. m. wide ; interspiral ridges present but 
indistinct. 
6. Chestnut Hill, Philadelphia, Pa. Spores distinctly of Tr. affinis 
type; elaters slightly spinulose, 4.5 mic. m. wide; interspiral ridges 
present. 
7. Gray’s Ferry, Philadelphia, Pa. Spores with broad bands, in a 
polygonal mesh, with only a single row of pits ; elaters 4.5 mic. m. wide, 
spinulose, spines 1.5 mic. m. long and broad interspaces between spirals ; 
iiiterspirai ridges present and distinct. 
8. East Park, Philadelphia, Pa. Spores of Tr. affinis type, with 
some Tr. Jackii spores ; elaters 4.5 mic. m. wide ; spinulose with spines 
1.5 mic. m. long; broad interspaces between spirals and interspiral 
ridges present and distinct. 
9. Fairmount Park, Philadelphia, Pa. (L. Thomas); spores distinct¬ 
ly of Tr. affinis type, but the bands with broken or interrupted meshes ; 
elaters 4.5 mic. m. wide and spinulose, ends of elaters long and thin ; in¬ 
terspiral ridges present and distinct. 
10. Thousand Isles, St. Lawrence river. Spores of both Tr. affinis 
and Tr. Jackii types, the former somewhat in excess ; elaters spinulose, 
4.5 mic. m. wide ; interspiral ridges present and very distinct. 
11. NewTield, N. J. (J. B. Ellis). Spores distinctly of Tr. affinis 
type, occasionally varying to the Tr. Jackii type; elaters spinulose, 4.5 
mic. m. wide; interspiral ridges present and very distinct.
