adhere by their summits being apparently held together 
by a brownish “gelatina hymenia,” and at intervals 
occur some which are brown throughout their whole 
length, and non-septate. These deserve more careful 
examination in the fresh state, as their function may be 
to convey from the subhymenial tissue the brown 
“ gelatina hymenia ” alluded to above. 
Name— Undulatus, waved.

Orbicular, even, brown; margin prominent, granulose 
beneath; fibrils pallid; asci cylindrical; sporidia 8, fusi- 
form, acuminate, bi-guttulate, uni-seriate, hyaline ; para- 
physes filiform.

Exs.—Winter, “Fungi Eur.,” 2406; Dr. Cooke, “On 
Stumps”; Fries, “Ad terram araneosam.” 
Scarcely exceeding 1 inch in breadth. The only 
British specimen I have seen is from Glamis, N.B., which 
has sporidia in no way differing from R. undulata. 
Name—JLevis, even; from the even hymenium. 
Order II.—PEZIZZ. 
Receptacle concave, plane, or convex, sessile or stipitate, 
fleshy or waxy; hymenium on the upper surface ; asci 
fixed, cylindrical, or clavate; sporidia usually 8. 
Receptacle adfixed by the centre, rarely by the whole 
under surface, or supported on a stem, more or less con- 
cave, often becoming plane or even convex ; substance
