ASCOMYCETES

which form elongated pits by forking ; yellowish or dingy- 
tawny olive, edges of ribs often darker. 5. 1 i n *> stout, 
whitish or pallid, hollow. In woods in spy. Uncommon. 
Mitrophora gigas differs from the above in being about 
twice the size, with a very stout stem more or less grooved, 
and sprinkled with minute rusty scales. A rare vernal 
species, growing in sandy places. 
Morchellaesculenta, ‘‘Common Morel.” Plate XLVI 1 I. 8. 
Asc. globose, 1^-2^- in. high and broad, adnate to the stem 
at the base, hollow; covered with stout, irregular ribs, 
forming polygonal pits ; colour variable—dingy yellow, buff, 
or tawny. 5 . 1J-2J in., stout, hollow, almost even, whitish. 
Gregarious. Frequent under elms on calcareous soils in 
spy. and early sum. Edible. The mould, Hypomyces cervinus , 
sometimes attacks the pileus, causing it to appear as if 
dusted with snuff. 
M. crassipes is much larger (sometimes a foot high 
and 7 in. diam.), the stem always much longer than the 
pileus. 
M. elata, a fir-wood species, has deep, thin ribs, which 
run in a parallel manner from the base to the apex of 
the pileus : stem always furfuraceous. M. conica is closely 
allied to it, but the stem is never scaly. 
Gyromitra esculenta, “ Lorchel.” Plate XLVIII. n. 
Asc. subglobose, somewhat depressed, i^-2j in. diam., from 
1-2 in. high, irregularly hollow, wavy, wrinkled, joined here 
and there to the stem, brown. S. ij-2f in., stout, more or 
less lacunose; stuffed, then hollow ; whitish. Terrestrial 
in spy ., in sandy fir woods. Rare. 
G. gigas is of larger size and paler colour. G. Phil- 
lipsii , found by Phillips in a field at Sherborne, in Ox¬ 
fordshire, is worthy of note here on account of its size. 
The pilei varied from 3 in. to 3 ft. in circumference, and 
somewhat resembled Spavassis cvispa. Gyromita includes 
some of the largest of the Discomycetes. It differs from
