XXIV. On a new Species of Helvella. By Wu PuiruiPs, P.L.S. 
(Plate XLVIII.) 
Read June 5th, 1879. 
IN a collection of Fungi gathered in 1876 on the Sierra Nevada mountains, in 
California, and sent for determination by Dr. Harkness of San Francisco, was a species 
of Helvella presenting characters essentially different from those of any species hitherto 
described. The specimens have evidently been dried with great care, and arrived here 
in a most satisfactory condition, which is not always the case with large and fleshy 
species. It is to be hoped that Dr. Harkness will continue to prosecute his researches 
in that highly interesting country, as there can be little doubt that it possesses many 
treasures to reward the labour of diligent investigation. 
HELVELLA CALIFORNICA, Phillips, n. sp. (Pl. XLVIII. figs. 1-6.) 
Pileus campanulate or saddle-shaped, deflexed, sublobate, free, veined beneath, 
purplish brown ; stipes longitudinally costato-lacunose, rosy pink; asci cylindrical, nar- 
rowed towards the base; sporidia 8, elliptic, binucleate ("017 x 009 millim.); paraphyses 
linear, clavate, and brown at the apices. | 
On the earth in dense forest, near rocks, Sierra Nevada mountains, California 
(Dr. Harkness, no. 1005). 
The pileus is from two to six inches in diameter, the stem from two to six inches 
high and about three quarters of an inch to one and a half inch in diameter. Its nearest 
ally is Helvella crispa, Fr., from which it differs in the colour of the hymenium and the 
stem, and in being a larger species.
