adjacent surfaces of contact stands out clearly, and is continuous 
from its attachment with the primordial tissue at the base of the 
stem and volva below to the apex of the stem at the point where 
the latter joins the pileus. 
While, as previously stated, there is quite a widespread belief 
that a veil is wanting in J. impudicus, there is abundant evidence 
that it was observed by the earlier students of these plants. CORDA 
(2) figured and described it as early as 1842. His figs. 1, 2, and 3 
show a thin veil. He calls it outer stem veil (dussern Strunke- 
schleier?). DEBARY (3, p. 207) speaks of it as a thin, white mem- 
brane between the pileus and stem, which is torn into fragments 
as the stem elongates. His language’ shows that various authors 
spoke of it as a veil (velum), and he himself uses the term after 
the expansion of the plant, when fragments of it cling to the stem. 
KALCHBRENNER (8a, p. 63) describes and figures it as present in 
Phallus imperialis Schulzer, which is but a form of I. impudicus 
(see Ep. FiscHer 6, p. 84). Fiscuer (6, p. 27) describes it 
as a hyphal weft between the stem and pileus in the mature egg. 
He regards it as a remnant of the primordial tissue, but does not 
speak of its appearance after the expansion of the plant. Burt 
(1b, p. 384) says that the veil is wanting in J. impudicus. In his 
characterization of the genus Jihyphallus he says “‘veil wanting.” 
By this he probably means that a persistent, entire veil, such as 
is usually present in Phallus ravenelii, is wanting in the genus 
Ithyphallus as interpreted by him. 
In Phallus ravenelii the veil is usually persistent, is composed 
of a thicker hyphal weft of primordial tissue, and is therefore not 
so easily torn into fragments, but persists as a campanulate, mem- 
branous collar suspended around the stem under the pileus from
