450 FUNGUS-FLORA. 



the excipulum give off numerous colourless, septate hyphae, 

 5-6 p thick, which fix the fungus to the ground ; asci 

 cylindrical, base narrowed and often slightly curved, 

 spores 8; obliquely uniseriate, elliptic-oblong, ends obtuse, 

 hyaline, often 1 2-guttulate, smooth at first, then becoming 

 distinctly asperate, 12-13 X 6-7 /j.; paraphy.ses cylindrical, 

 1-5 p thick, becoming slightly clavate and yellowish at the 

 apex.

On the bare ground. 



Gregarious or sometimes crowded ; the disc is sometimes 

 of a deep primrose yellow colour. Distinguished from P. 

 aurantia by its smaller size, but probably nothing more than 

 a small form of the last-named species. This affinity was 

 observed by Berkeley and Broome, who say in a note 

 following the diagnosis, " resembling at first sight stunted 

 specimens of Pez. aurantia, but essentially different, not only 

 as proved by the habit, but the smooth, not echinulate or 

 pointed spores." The spores are certainly rough when 

 perfectly mature, as first observed by Phillips, so that now 

 there remains but little more than the smaller size of the 

 ascophore and the spores. Type specimen examined. 



Otidea leuculenta. Mass. 



Ascophore 13 cm. across, sessile, fleshy, subglobose then 

 expanded and concave, often wavy ; disc bright orange- 

 yellow, externally paler in colour and downy, the down 

 becoming more abundant away from the margin, and fixing 

 the fungus to the soil, excipulum parenchymatous, cells 

 large; asci cylindrical, slightly narrowed at the base, 

 spores 8, obliquely uniseriate, elliptic-oblong, hyaline, for a 

 long time perfectly smooth and 2-guttulate, finally the 

 epispore becomes oraamented with delicate raised lines 

 anastomosing to form a polygonal network, 23-25 x 10-11 /A; 

 paraphyses cylindrical below, the upper half very slightly 

 and gradually expanding to form a clavate apex which is 

 filled with orange granules, sometimes sparsely septate.
