Disc bright scarlet ; stem equalling the height of the cup, 

 4 mm. 



Not examined. 



Var. atromarginata, Phil. & Plow., Gard. Ohron., 

 Feb. 11, 1882, with fig. ; Phil., Brit. Disc, p. 67. 



Ascophore 1-2 • 5 cm. across, disc blood-red, wrinkled ; 

 margin black, owing to the presence of minute, septate, 

 bristle-like hairs ; the tuberculate spores are frequently 

 furnished with thread-like appendages at the extremities, 

 pointing in opposite directions obliquely to the long axis of 

 the spores. 



Not examined. 



The " septate, bristle-like hairs " at the margin appear to 

 separate this variety from the, neighbourhood of P. aurantia. 



Otidea fibrillosa. Mass. 



Ascophore sessile or with a very short stem-like base, 

 2-3 cm. broad, when young the margin is involute, after- 

 wards erect, often divided on one side, rather fleshy ; disc 

 orange ; excipulum composed of large cells, the external 

 ones of which give origin to thick, wavy, interwoven, 

 colourless, septate hyphae, 5-6 fj. thick, which form a dense 

 whitish tomentum outside, quite up to the margin; asoi 

 cylindrical, attenuated at the base, spores 8, uniseriate, 

 arranged obliquely or straight, hyaline, smooth, elliptical, 

 ends obtuse, eguttulate, 15-17 X 9 /*; paraphyses cylindrical 

 2 fj, thick, ending in a globose, orange-coloured head, 4-5 /j. 

 diameter.

On the ground. Autumn. 



Somewhat resembling P. aurantia, but known from this 

 and allied species by the globose heads of the paraphyses, 

 apparently constantly smooth, eguttulate spores, and tomen- 

 tose exterior of ascophore. 



Otidea luteo-nitens. Mass. 



Ascophore J-1^ cm. broad, globose when very young, then 

 concave, at length more or less plane, wavy, and irregular ; 

 disc bright orange-yellow, externally rather paler, glabrous 

 for a short distance from the margin, then the large cells of
