TRICHIA 273 



above the abandoned vasiform peridia. The figures of Bulliard are 

 unsatisfactory, although the description he gives and the name he sug- 

 gests, still current, may lead us to concede that he had our species 

 before him. The spores are larger than in T. persimilis, and the 

 episporic net different, the "border" wider. The Plasmodium in the 

 latitude of Iowa not uncommon in woods in June, after emerging 

 passes into fruit in the laboratory in about forty-eight hours, and the 

 rupture of the peridia follows presently. The hypothallus is quite 

 distinct, extra-marginal, and in substance like to the peridial wall. 



Not rare. Throughout the northern forests, Maine to Washington 

 and Oregon, south to Alabama, Louisiana, Mexico. 



8. Trichia verrucosa Berk. 



I860. Trichia verrucosa, Fl. Tasm., II., p. 269. 



Sporangia pyriform, or obovoid, shining, ochraceous from the color 

 of the contents, stipitate, more or less botryoid or connate ; stipe twice 

 the height of the spore-case, reddish brown, simple or consolidated 

 with others, weak, inclined, or procumbent ; hypothallus distinct ; 

 spore-mass ochraceous yellow, the elaters simple, with smooth tapering 

 points, with spirals three or four, the spores beautifully and strongly 

 reticulate, after the manner of the spores in the species preceding, 

 with the meshes generally complete and always large, quite variable 

 in size 12—16 /n. 



Rostafinski quotes the species {teste Lister) from Chile. Specimens 

 in the herbarium of the State University of Iowa are from Jalapa, 

 Mexico, collected by Mr, C. L. Smith. The species may be therefore 

 expected in the southern United States. Berkeley described it from 

 Tasmania. T. superba Mass. from description would seen to be the 

 same thing. 



9. Trichia pulchella Rex. 



1893. Trichia pulchella Rex, Proc. Phil. Acad., p. 366. 



Sporangia solitary or in groups of four or five, bright vitelline yel- 

 low, sessile ; the peridium thin, transparent, opening irregularly above ; 

 hypothallus none ; capillitium bright yellow, not emergent, the threads
