TRICHIA 275 



A species remarkable for its variations in color. More commonly 

 the unopened sporangia are opaque brown, by reason of a dense outer 

 wall, and more frequently simple, or if compound, show but two or 

 three united. The reddish variety, vinous or scarlet-black in color, is 

 remarkably fasciate. Some clusters show twenty or more stipitate, glo- 

 bose sporangia, conjoined by their distinct but coherent stems. In 

 such fruitings the sporangia are small, .5 mm. In the brown sporan- 

 gia the dehiscence, as stated, is often definitely prefigured; in the 

 multiple, red, obscurely, if at all. As presented in collections from 

 the eastern United States, the two forms might well be disjoined. 

 Persoon, however, discussed both together and so they remain. 



Saccardo includes Craterium floriforme Schw. here. 



By the descriptions of the earlier authors it is impossible to dis- 

 tinguish this from H. vesparium on the one hand, and T. decipiens 

 on the other. T. botrytis Pers., /. c, 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. Rosta- 

 finski rejects Persoon's names simply as not pertinent in every case. 

 Massee examined the specimens of Leveille, and finds them belong- 

 ing here; but see our No. 14, seq. 



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

 York, Pennsylvania, Ohio, Colorado ; Toronto.

Sporangia gregarious, scattered, dull tawny brown, shading to 

 dark brown below, about ^^ mm. in diameter, globose, stipitate ; 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 jx wide, adorned with spirals four, which wind 

 unevenly, are perfectly smooth, and terminate in abrupt tips about 

 twice the diameter of the elater; spores yellow, under the lens yel- 

 low, minutely and closely warted, globose, 12 fj..
