TRICHIA 2 1 5 



A common and beautiful species recognizable at sight, after 

 the peridia break, by the aggregate capillitium constantly in 

 evidence above the abandoned vasiform peridia. The figures 

 of Bulliard are unsatisfactory, although the description he 

 gives and the name he suggests, 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 Wash- 

 ington and Oregon, south to Alabama, Louisiana, Mexico. 



8. TRICHIA VERRUCOSA Berk. 



1860. 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 gener- 

 ally complete and always large, quite variable in size, 12-16 /n. 



Rostafinski quotes the species (tcste Lester) from Chili. 

 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 seem 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
