ing stipe and cap would use most of this in their development, 

 so that at elongation of plant no real veil would appear. In other 

 words, it would cling to the under side of the cap and to the 

 inner surface of the volva ; but if the amount of water during 

 the growing season was in excess of the quantity usually present, 

 then this tissue with others v/ould be more strongly developed 

 than normally and therefore would be more likely to appear as a 

 veil at maturity of the plant ; or if from any cause, as cold, re- 

 moval from earth, etc., the later developm.ent of plant should be 

 checked, then this tissue would appear as a veil ; this is only an 

 hypothesis the proof of which remains yet to be worked out. At 

 any rate the fact remains that in these two species the veil may 

 or may not be present, and when present may be a mere thin 

 membrane or one of appreciable thickness and permanency that 

 will and does persist when the plants are dried or when kept in 

 fluids. The presence of a A^eil on Phallus impudicus has been 

 noted and discussed before by Van Bambeke,* also by Ed.

Phallus impudicus. L. var. imperiatis, Schw. (Figs. 1-4). — 

 Eggs usually solitary, but sometimes in groups of two to eight 

 individuals from a common root like rhizomorph, the mycelium 

 and eggs pink changing to a dark purple tint when injured. 

 Eggs ovate to irregularly globose, from two cm. tall by one and 

 a half to two cm. thick to twelve cm. tall by ten cm. thick. Stipe 

 fusiform hollow, white changing to cream white with age, four 

 to twenty cm. tall by two to four cm. thick. Walls of stipe of 

 several layers of chambers thick, which open into both inner and 

 outer surface of the stipe as pits, chambers isodiametric pseudo- 

 parenchymatous, stipe open at apex (perforate) and joined to 

 pileus by a broad white collar. 



Pileus conic-campanulate, strongly and deeply alveolate, 

 reticulate, white, three to seven cm. tall and two to five cm. 

 broad, floccose. gleba at first a greenish brovrn turning black- 

 brown in age, strongly foetid. Veil wanting or when present 

 membranous floccose, white beneath pileus or in bands and 

 patches on stipe or clinging to stipe inside volva, attached to 

 and continuous with inner cup-like part. Spores oblong, one and 

 a half by four /a. Volva pink rupturing irregularly. 



In rich loose soil, in open fields or near margins of thickets, 

 along creeks, etc., never in well shaded places. Denton, Texas, 

 and one specimen from Austin, Texas, Nov. to Jan. 



This was our most abundant Phallus in Fall of 1902. It was 

 first collected October the twentieth and specimens were found 

 from then till the middle of January, 1903. On October the
