TEZIZA. 427 



roundish, depressed, the margin very connivent, and the base 

 within umbilicate and plicate. Dining the period of growth, 

 the general form becomes more depressed, and a number of 

 lacerations are produced, of which one or more often reach to 

 the centre. In the last stage the pileus is nearly spread out 

 on every side, so as to rest on the ground, the extreme 

 margin, however, still retaining its involute tendency ; the 

 centre is now much reticulated with anastomosing ribs, un- 

 dulate and unequal, especially when there is a stipes, from 

 the sides being partly deflexed. Stipes either present or 

 nearly wanting : when present, half an inch high or more, 

 and nearly as thick, lacunose. Substance carnose, fragile, 

 one-tenth to one-eighth of an inch thick. Sporules 8, oval.

Scattered, narrowed below into a short, stout, stem-like 

 base, globose and closed at fir&t, then cup-shaped, finally 

 almost plane, or arched near the margin and the extreme 

 edge slightly raised ; flesh thick, brittle, 2-10 cm. across, 

 2-4 cm. high ; disc irregularly wrinkled or nodulose, greyish- 

 brown, often with a purple tinge, externally whitish with 

 more or less prominent ribs spreading from the base; hypo- 

 thecium and excipulum formed of stout, interwoven hyphae 

 which become compact to form the cortex ; asci cylindrical, 

 apex slightly truncate, 8-spored; spores obliquely 1-seriate, 

 smooth, continuous, elliptical with a prominent apiculus at 

 each end, usually 3-guttulate, 27-34 x 11-13 /x; paraphyses 

 stout, septate, clavate and brown at the apex, which is 7-9 /a 

 thick.

On damp ground. 



Eeadily distinguished by the large ascophore, which is 

 wrinkled and plane at maturity, and by the large elliptical, 

 strongly-apiculate spores, which are slightly tinged brown 

 at maturity. Iodine does not colour apex of ascus blue.
