Seated on a widely elfused, black crust. Peritliecia short, scat- 

 tered, thick, oI)long-ovate, sul>truncate, generally contracted into a 

 I)seudo-stipitato base, obtuse at the ends, Idack: lips ga|)ing, infle.xed. 

 This is the diagnosis given by Schweinitz. The specimen in Ileili. 

 Schw. does not show any black crust, nor can the peritliecia be called 

 even pseudo-stipitate; they are only erumpont-superficial, |-1^ iiiiii.

 overlapping, sul)biscriate, fnsoid, slightly curved, G-8-septate, with one 

 joint (about the third from the top) slightly swollen, reddish-brown, 

 ends narrowed but subobtusc, 25-30 x 0-8 /«. 



I^und by Schweinitz in Carolina, on hard, decaying wood. Speci- 

 mens collected at Pouglikeepsie, N. Y., on old chestnut wood, have 

 the sporidia 30-40 x 7-9 /z, which is about the size of those in a spec. 

 on an old pine shingle found at Newlield, N. J. Sec. Cooke, Grev.

The specimens in N. A. F., 400, were determined by Gerard frnia 

 authentic specc. of ^. complanafiim, sent him by Duby. '{'he species 

 seems to be a variable one, both in the form of the peritliecia and in the 

 nuinl»er of septa in the sporidia. Duby says 3-5-sei)tate. In the 

 X. A. F. specc. the spoi'idia ai-e 3-7 (mostly 5-) septate and 25-30 .\
