TRICHIA 2 1 / 



or rarely branched, long-fusiform, about 4 /* thick at the centre, 

 tapering gradually to the long acuminate but finally blunt tips, 

 the spirals four, even, smooth, rather closely wound and trace- 

 able almost to the apex ; spores concolorous in mass, under the 

 lens pale, globose, more or less closely minutely warted but not 

 reticulate, 10-12 /JL. 



A species remarkable for its variations in color. More com- 

 monly the unopened sporangia are almost black, and the capil- 

 litium crimson or brick red, resembling that of Hemitrichia 

 vesparium. In other cases the peridium is dull, opaque brown, 

 by reason of a dense outer layer of brown granules, and pallid 

 streaks of dehiscence show plainly. The sporangia reach some- 

 times 4 mm. in height, but are usually much shorter, the stipe 

 one-half. 



By the descriptions of the earlier authors it is impossible 

 to distinguish this from H. vesparium on the one hand, and T. 

 dccipiens on the other. T. botrytis Pers., I.e., gives us first secure 

 foothold. Fries discards Persoon's appellation as unsuitable 

 and improperly applied, and takes up what he deems an older 

 specific designation, T. pyriformis Leers. But Rostafinski is 

 certain Leers had A. punicea in mind, and that other early 

 names are equally ill applied. Rostafinski rejects Persoon's 

 name simply as not pertinent in every case. Massee examined 

 the specimens of Leveille, and finds them belonging here. 



Not common, but with wide range. Maine, Massachusetts, 

 New York, Pennsylvania, Ohio, Oregon, Washington.

1890. Trichia subfnsca Rex, Proc. Phil. Acad., p. 192. 



Sporangia gregarious, scattered, dull tawny brown, shading 

 to dark brown below, about \ mm. in diameter, globose, stipi- 

 tate ; stipe short, about equal to the sporangium, stout, brown 

 or brownish black, rugulose, solid ; capillitial mass bright straw 

 color ; the elaters long cylindrical, 3-4 p wide, adorned with 

 spirals four, which wind unevenly, are perfectly smooth, and 

 terminate in abrupt tips about twice the diameter of the elater ;
