Illinois. Urbana. McDougall, coll. (U. N. C. Herb.). 



Colorado. Seavcr, coll. (N. Y. B. G. Herb., as P. impcrialis). Seaver says this rosy plant is common 



in the West and is a rosy form of /. impudicus. 

 Minnesota. Elk River. Baitey, coll. (U. S. Nat'l. Herb., as P. Ravendii). 

 Kansas. Lawrence. Det. by Underwood. (U. N. C. Herb.) 



Ithyphallus rubicundus (Bosc) E. Fischer 



We have not seen this and adapt the following from Long (I.e., p. 109): 



Eggs white, solitary or in groups of 2-6 individuals from a common mycelium, 

 when in groups usually one large plant surrounded by small ones, ovate to globose, 

 2-3 cm. tall by 1-3 cm. thick. Stipe cylindric-fusiform to fusiform, hollow, scarlet, 

 9-15 cm. tall by 1.5 to 2.5 cm. in diameter, walls of several chambers thick, which open 

 onto outer and inner surfaces of stipe as pits; chambers isodiametric, pseudo-paren- 

 chyma tous; apex perforate or imperforate, but usually perforate as the plant ages, by 

 scarlet top of apex falling entirely off of plant; joined to pileus by a narrow irregular 

 scarlet collar or ring. Pileus conic, smooth or rugose, scarlet, sometimes extending 

 below gleba into a narrow sterile border, whose edges are finely crinkled to dentate, 

 pseudo-parenchymatous, 1-2 cm. wide to 2-3 cm. tall. Gleba at first isabella color, 

 becoming a dirty yellowish brown when deliquescing, odor very foetid. Veil wanting 

 or when present, membranous floccose, white beneath pileus or in bands or patches on 

 the stipe or clinging to stipe within volva as in /. impudicus. Spores oblong, 2 x 4/j. 

 In lawns and open grassy places, Austin, Tex., April, May, and Nov., 1900, or in old 

 sandv fields near rotting oak stumps and along fences in sandy soil. Denton, Tex., 

 Nov. to Jan., 1902 and 1903. 



Lloyd thinks that Phallus aurantiacus Mont, is the same as this (Myc. Notes, p. 

 330 and Syn. Known Phalloids, p. 14).

DICTYOPHORA Desv. 



With the characters of Ithyphallus except that there is a large campanulate, veil- 

 like, netted indusium that is attached to the stem tip under the cap and extends far 

 below it. Atkinson has shown (1. c.) that this indusium is a distinct organ and not 

 homologous with the short, membranous veil of Ithyphallus. The species here included 

 is the only one known in the United States.

Plates 11-14 and 105 



Our largest and most massive Phalloid, arising from a large egg which is subspheri- 

 cal, ovate or sometimes flattened, about 4-4.5 x 4.5-5 cm., when flattened up to 7 cm. 

 broad and 5 cm. high, white and plicate below as in a peeled orange, the upper half 

 smooth, pale flesh color to deep fleshy brown; in the center below is given off a large,
