south to Arkansas and Alabama; Europe, North Africa, India, Ceylon, 

 Manchuria. 



Var. olivacea Brandza differs only in the olivaceous color of the 

 sporangium and the Plasmodium. 



9. Trichia scabra Rost. 



Mon. 258. 1875. 

 PL XIX, Figs. 502, 503. 



1889. Trichia nitens Fr. ex Mass., Jour. R. Micr. Soc. 333. 



Sporangia sessile, closely crowded upon a well-developed hypothal- 

 lus, regular, globose or turbinate-globose, 0.6-0.8 mm. in diameter, 

 orange or golden brown, smooth, shining; capillitial mass clear golden 

 yellow, or sometimes rusty orange, the elaters simple, long, 4-5 ju in 

 width, the spirals three or four, closely wound, spinulose, even and 

 regular, the apices short, acuminate; spore-mass concolorous; spores 

 yellow under the lens, covered by a delicate fine-meshed network, 

 often incomplete, appearing simply spinulose under low power, 10- 

 12 ju. Plasmodium white. 



Generally a well-marked species, easily recognized by its regular 

 but roughened capillitial threads. Under an oil immersion objective 

 the spores are also diagnostic. To the unaided eye it resembles T. per- 

 similis both in color and habit. Fructifications two inches or more in 

 length and half as wide are not infrequent on the lower side of fallen 

 stems in forests of deciduous trees. 



Not uncommon. Maine to Washington, Oregon, Alaska, and south 

 to Missouri and Arkansas. North temperate regions generally. South 

 Africa, Ceylon. 



Trichia asiatica Skvortz., 1931, is probably this species. The spores 

 are said to be minutely warted, but this is often their appearance under 

 a dry lens. 



10. Trichia favoginea (Batsch) Pers, 



Roemer N. Mag. Bot. 1 : 90. 1794.

1805. Trichia chrysosperma (Bull.) DC, Fl. Fr. 2 : 250. 



Sporangia closely crowded, cylindric or prismatic by mutual pres- 

 sure, obovoid, sessile, 0.6-0.7 mm. in diameter, 0.7-1.6 mm. tall, 

 olivaceous yellow, smooth and shining; peridium thin, opening above 

 somewhat stellately, persistent; capillitium golden yellow, escaping
