PHALLACEAE 9 



which are traversed their entire length by a shallow furrow having its surface con- 

 tinuous with the surface of the stipe; cavity of the stipe nearly closed at the base of the 

 arms by a thin diaphragm opening above into a closed chamber with dome-shaped 

 wall even on its inner surface and adherent to the arms for about one-sixth their length; 

 gleba brownish olive-green, supported upon the dome and closely embraced by the 

 arms; spores simple, olive-green, ellipsoidal, 3-4 x 1.5/x, 5-8 on septate and constricted 

 basidia. 



"Total height of plant 10-12 cm. ; arms one-sixth of this; greatest diameter of stipe 

 15 cm." 



As Lloyd supposes, this species is almost certainly introduced from the tropics or 

 south temperate regions. 



The basidia as described by Burt are most remarkable. They are constricted at 

 intervals so as to appear like a row of beads, a form apparently unknown in other 

 Basidiomycetes. Individual plants vary greatly in size: in those we have seen, the 

 arms in the dry state varying from 1 to 3.6 cm. in length. In addition to plants seen 

 which are cited below, the species has been reported from Ohio, Connecticut, Mas- 

 sachusetts, England and Germany. (See Lloyd, Myc. Notes, pp. 183, 219, 386, 515; 

 Beardslee, Ann. Rept. Ohio St. Acad. Sci. 9: 19. 1901; Sumstine, Ohio Naturalist 

 6: 474. 1906; Stockberger, Ohio Naturalist 6: 517.) 



Lloyd thinks it very probable that L. anstraliensis (see figure by Rea in Trans. 

 Brit. Myc. Soc. 2: pi. 3, fig. A. 1904), L. Clarazianus and L. Gardneri are all the 

 present species (Myc. Notes, p. 594). 



A variety of this species ( Klitzingii Hennings) has been described from Germany 

 (Hedwigia 41: 167. 1902), differing only in paler color and absence of green in the 

 gleba (see Rea, as cited under the genus).

MUTINUS Fr. 



Receptaculum formed of a distinct, delicate, hollow stalk as in Simblum, but 

 differing in the spore slime being borne on the outside of the upper part of the stalk 

 itself, which is smooth and more or less pointed, the tip often perforated. Color rosy 

 red above (under and below the deep olive slime), fading downward. Volva soon col- 

 lapsing against the base of the stalk.
