GYR0M1TRA. 477 



slightly tinged brown at maturity; paraphyses septate, 

 gradually becoming clavate, 8-10 fx thick at the brownish 

 tips. 



In fir woods. Spring. 



A very distinct and beautiful species, easily recognised 

 by the deep, thin, more or less parallel ribs running from 

 base to apex of the ascophore. The entire substance is 

 thin. The usual size is about as follows : ascophore 5—7 

 cm. high and nearly as broad, stem 6-8 cm. long, 2J— 3J cm. 

 thick; but Irish specimens recorded by Mr. Greenwood 

 Pirn measured 25 cm. high, the ascophore being 12 cm. 

 high, and nearly as much across. 



Specimen from Fries, in Herb. Berk., Kew, examined.

 Brit. Disc, p. 4 ; Cooke, Mycogr., fig. 315 ; Sacc, Syll., viii. 

 n. 10 (fig. 31, p. 188). 



Pileus stipitate, adnate at the base to the stem, elongated, 

 slightly conical, or sometimes almost cylindrical, apex 

 obtuse, hollow, the cavity continuous with that of the stem, 

 primary ribs stout, deep, edge obtuse, irregularly longi- 

 tudinal, often forking and anastomosing, joined by slender 

 transverse ridges, thus forming irregular, elongated pits, 

 greyish bistre or olive bistre, 4-7 cm. high, 2-3*5 cm.' 

 broad; stem cylindrical, whitish, minutely villose, hollow, 

 1*5-3 cm. high, 1 cm. more or less thick; asci at first 

 cylindrical, then clavate, 8-spored; spores hyaline, con- 

 tinuous, smooth, elliptical, 16-18 x 8-9 /*., 1-seriate at first, 

 then irregularly 2-seriate ; paraphyses septate, cylindrical 

 or clavate, stout.

On the ground. Edible. 



Agreeing with M. elata in the longitudinal ribs of the 

 pileus, but differing in its smaller size, and in the stem not 

 being furfuraceous. 



GYEOMITRA. Fries, (figs. 14-16, p. 188.) 



Ascophore stipitate ; hymenophore subglobose, inflated 

 and more or less hollow, or cavernous, variously gyrose 

 and convolute at the surface, which is everywhere covered
