Trichia persimilis Karst. Concepcion, Chile, November, 1905. 
Trichia decipiens (Pers.) Macbr. Punta Arenas, Chile, Eeb- 
ruary and March, 1906. These specimens vary considerably in 
general appearance from that usually presented. The sporangia 
are yellowish clay-colored, in some cases almost or quite sessile, 
and the upper half of the wall breaks away in an even line, leav- 
ing the lower portion as a well-defined cup. These crowded, 
nearly sessile sporangia bear a peculiar resemblance to those of 
Cribraria argillacea.

Arenas, Chile, Eebruary, 1906. 
Trichia Botrytis var. munda List. Corral, Chile, December, 
1905.

ber, 1905.

ber, 1905. 
Arcyria insignis Kalchbr. & Cke. Llavallol, Argentina, 
March, 1906. This specimen lacks the characteristic color, being 
weathered to a dull-yellowish-brown. In other respects it is 
typical. 
Arcyria incarnata Pers. Concepcion, Chile, November, 1905 ; 
Punta Arenas, Chile, March, 1906.
