are truly parenchymatous, whilst a central zone consists of- 

 densely interwoven, hyaline hyphae. 



Otidea auricula. Mass. (non Bresad.), Grev., vol. xxii, 

 p. 65. 



Somewhat caespitose or solitary, rather fleshy, elongated 

 on one side, the short side cut down, narrowed below into a 

 more or less distinct stem-like base, the two margins 

 involute and approximate when young, then expanding into 

 the form of a hare's ear, or sometimes shorter and blunter ; 

 coriaceous when fresh, becomitg rigid when dry, 3-6 cm. 

 high, and 3-4 cm. across ; disc yellowish-brown, with a 

 flesh-coloured tinge, externally similar or a shade paler ; 

 excipulum parenchymatous, cells very large, mostly elon- 

 gato-hexngonal, 35-60 x 25-30 fi, becoming suddenly small, 

 but yet parenchymatous towards the surface; asci cylin- 

 drical, base narrowed into a slender, usually flexuous pedicel, 

 apex truncate, S-spored; spores obliquely 1 -seriate, hyaline, 

 continuous, smooth, eguttulnte, 25-30 X 12-14 /i ; para- 

 physes scanty, equal in length to the asci, slender, septate, 

 the upper third gradually expanding into a clavate tip 

 5-6 /A broad, hyaline.

On the ground. 



We consider the fungus figured by Cooke, in Mycogr., 

 fig. 213, called Peziza {CocMeata') auricula, to be identical 

 with the plant in Sohaeffer's Icon., t. 156, called Elvela 

 auricula, notwithstanding the remarks of Bresadola and 

 Eehm to the contrary. Schaeifer's description com- 

 mences with "Est fungus unicolor," which is true of 

 Cooke's fungus, whereas the fungus upheld by Bresadola 

 and figured in Fungi Tridentini, t. Ixxiii., is described as 

 being externally " Ex albido-luteola, marginibus ochraceis, 

 disco laete fuho-odhraceo, demumque badio-fulvo." Eehm 

 has the same species in view as Bresadnln, and in the 

 comments of his Ascom., Fasc. xiv., in " Hedwegia," 1883, 

 p. 34, has ■' 1)52, Otidea auricula (Cooke sub Peziza) ; com-
