Ithyphallus impudicus (L.) Fr. 



Plate 10 



This is a rare plant east of the Mississippi and, except for doubtful early records, 

 as Schweinitz and Curtis, seems to have been recorded only twice in that territory. 

 The American form seems to have consistently a pink volva which is elongated or egg- 

 shaped and may be best considered as I. imperialis or as a variety of /. impudicus. 

 The latter is said by some to have in Europe a round, white volva (see Lloyd, Myc. 

 Notes, p. 327 and 328, also p. 508), but Rea (British Basidiomycetae, p. 23) says the 

 volva is round or oval and Hollos shows one with an oval, very pink volva. We have 

 not seen the plant alive and take the following measurements from Dr. W. B. 

 McDougall. 



Buttons oblong or egg-shaped, pinkish, much like those of /. Ravenelii, 3-4.5 x 

 3.5-6 cm.; expanded plant 7.5-15 cm. tall; cap up to 4.5 cm. long, deeply reticulated 

 with large chambers, which are at first filled with olivaceous slime, apically attached 

 (in the plant we have) to a broad (1.3 cm.) white expansion of the stem apex which is 

 not perforated; a thin, membranous, non-perforated veil is present between the cap 

 and the stem and a thicker basal portion surrounds the stem attachment in the volva 

 base. Odor very putrid. 



Spores (of plant from Urbana, 111.) color of the slime, 1.4-1.7 x 3-3.7/a, short- 

 elliptic, smooth. Spores of a typical plant from England in the New York Botanical 

 Garden (Kew Gardens; Murrill, coll.) are 1.3-2 x 3.2-4.2/1.
