 as in the typical form. 



Peziza tectoria, Cooke, Grev., iii. p. 119; Mycogr., fig. 263 ; 

 Phil., Brit. Disc, p. 77 ; and Sacc, Syll., viii. n. 325. 



On damp plaster walls and on wood. 



Type specimen examined. 



At first appearing as a small white furfuraceous ball, seated 

 on a white mycelium ^ in. across ; when old becoming very 

 irregular in form, If in. across ; margin rather thick and jagged. 

 The tips of the asci are clear blue with iodine. (Cooke.) 



I can discover no specific difference between P. tectoria and 

 the specimens previously mentioned as being accepted and 

 figured by Cooke as P. ampliata, neither can I indicate a 

 varietal distinction, except in habitat. As stated by Cooke, 

 the tip of the ascus becomes deep blue, the remainder very 

 pale blue when treated with iodine.

Scattered or gregarious, closed at first, soon almost plane, 

 sessile, rather fleshy, margin minutely crenulate ; disc pale 

 buff or with a tinge of tan-colour, externally paler, delicately 

 farinaceous, 8-12 mm. across, hypothecium and excipulum 

 hyaline, formed of interlacing hyphae which pass into a 

 parenchymatous cortex consisting of irregularly polygonal or 

 almost circular cells 10-15 p diameter, the marginal teeth 

 are formed or smaller, slightly elongated cells ; asci elongated, 

 cylindrical, apex obtuse, 8-spored, pedicel long and stout ; 

 spores obliquely 1 -seriate in the upper portion of the ascus, 

 hyaline, smooth, continuous, broadly elliptical, ends obtuse,

 thickened at the tips. 



On the ground ; on charcoal beds, &c. 



Cups scarcely J an inch broad, very neat and delicate,
