Mutinus Curtisii (Berk.) E. Fischer 

 M. hovinus Morgan 

 M. elegans Mont. 



Plates 75 and 76 



Plant about 10-17 cm. high, the white volva at first spherical then 

 elongating and on rupturing at the apex collapsing against the stalk 

 which is almost cylindrical for the first third and up to 2.5 em. thick, 

 then tapers gradually upward to the blunt point; spore-bearing 

 (slimy) part composing about 3-5 cm. of the apical end, similar in 

 superficial appearance to the rest of the stem except for the slime; 

 color bright rosy red under and below the slime, gradually fading to 

 watery white or flesh color below; apex perforated by a small open- 

 ing ; volva rooted by a strong cord ; odor of the brownish slime very 

 strong and offensive. 



Spores (of No. 5113) smooth, elliptic, 2-3 x 4-7/x. Wall of the 

 very hollow stem about 2-3 mm. thick and composed of one or two 

 layers of small thin-walled chambers which are irregularly isodiamet- 

 rical ])elow and change gradually to radially elongated and definitely 

 to a single layer in the slime-bearing part. Walls of the chambers of 

 the stalk 90-95)u, thick, with only 3-4 layers of cells ; of the spore-bear- 

 ing part 55-75/x thick with 3-4 layers of cells. 



The plants usually appear singly in woods or groves.

ITHYPIIALLUS 



Volva and stalk as in Mutinus, l)ut the spore slime is borne on 

 the outside of a thin, pendent, campanulate membrane or cap which 

 is free from the stem except at the tip. Between this cap and the 

 stalk above and between the volva and the stalk below another deli- 

 cate, white membrane or veil is obvious (at least in /. Ravenelu).
