14. Elvela Underwoodii Seaver, nom. nov. (Plate 43.) 

 Gyromitra brunnea Underw. Proc. Ind. Acad. Sci. 1893: ii. 1894. 



Pileus much contorted, irregularly lobed and plicate, in 

 places faintly marked into areas by indistinct anastomosing 

 ridges, adhering to the stem at various points, whitish under- 

 neath, reaching a diameter of 5-12 cm. in the widest point; 

 hymenium chocolate-brown (lighter when covered by leaves) ; 

 stem reaching a length of 8-13 cm. and a diameter of 2-5 cm., 

 rarely slightly lacunose, hollow or loosely stuffed, white; asci 

 cylindric or subcylindric; spores ellipsoid, 14 X 28-30 /i, usually 

 containing two rather large oil-drops, becoming sculptured; 

 spore-sculpturing consisting of small warts or faint reticulations; 

 paraphyses slender, enlarged above. 



In rich woods on leaf-mould. 



Type locality: Putnam County, Indiana. 



Distribution: Indiana and Ohio. 



Illustration: Hard, Mush./. 419. 



The name assigned by Underwood is untenable in this genus 

 since the Elvela brunnea was used by Linnaeus for an entirely 

 different species. The name Elvela Underivoodii is therefore 

 adopted.

 of 2-3 cm. and a length of 4 8 cm., whitish or slightly pinkish, 

 deeply lacunose or fluted, the ribs extending up underneath 

 the pileus like the ribs of an umbrella; asci cylindric or sub- 

 cylindric, reaching a length of 150 )U and a diameter of 10-12 ^; 

 spores 1 -seriate, globose, reaching a diameter of 10 /x; paraphyses
