8 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



Our plate 3 shows an abnormal variation of two plants springing from one volva 

 and fused at their tips. This is apparently of not rare occurrence as a similar example 

 is shown in Lloyd's Myc. Notes No. 24, fig. 133, from a photograph of a Brazilian plant 

 by Rick, and another such is illustrated by Gerard in his plate 2 (as cited below).

ANTHURUS Kalch. 



Phalloids with a hollow, spongy, subcylindrical stem springing from a volva and 

 bearing at the top several spongy arms which in youth embrace the dark gleba which 

 covers their inner faces and sides; at maturity either remaining connivent at the tips or 

 bending more or less strongly outward. 



There is a difference of opinion as to the correct definition of the genera Lysurus 

 and Anthnrus. As originally described, in Lysurus the gleba is borne on the outside 

 faces of the arms, while in Anthurus the gleba is described as enclosed within the arms 

 in youth and covering their inner and side faces at full maturity, a dorsal zone remaining 

 bare. We are following Burt and Fischer (Phalloideen, part 3, p. 41) in including our 

 species in Anthurus. Lloyd (Syn. Known Phalloids, p. 35) and Rea (Trans. Brit. 

 Myc. Soc. 2: 57. 1904) would put the species in Lysurus, modifying that genus to 

 include certain species with the gleba on the inner surfaces of the arms. 



The genus Anthurus is described by Kalchbrenner (Grevillea 9: 2. 1880) as 

 having the stem conspicuously flaring at the top and passing into several broadly spread- 

 ing arms which bear the spore slime on the inner surface. The description does not 

 state that the arms pass directly into the stem without a groove or abrupt change of 

 texture, but the original figure of the type species (A. Mullerianus) has this appearance, 

 and Fischer's figures of the same species are in agreement. Anthurus aseroeformis, a 

 better known plant, is said to have this structure. Lloyd thinks these two species may 

 be the same (Myc. Notes, p. 408, fig. 244). 



In the eastern United States there is but one representative, and that is found in the 

 northern and central sections. There may be another American species, as a name 

 (Lysurus Texensis Ellis) has been referred to without description (Bull. Torr. Bot. 

 Club 7: 30. 1880), and Lloyd mentions a red Lysurus in Texas seen by Prof. Long 

 (Syn. Known Phalloids, p. 40; also Myc. Notes, p. 407). In Mycological Notes, pp. 

 586 and 647, Lloyd reports L. Mokusin from hothouses at Chico, California, where it 

 was probably introduced from the Orient. 



Anthurus borealis Burt 



We take the following description from Burt (Mem. Boston Soc. Nat. Hist. 3: 

 504. 1894) : 



"Solitary or subcaespitose. Stipe white, clavate, divided above into 6 erect, 

 narrowly lanceolate, hollow arms incurved above, and with pale, flesh-colored backs
