section fall on either side, it appears to be central. In an injured 

 specimen I find the cells darker, and mixed with the spores are 

 a multitude of smaller globose bodies. 



This species is doubtless extremely near to H. Pompholyx, of 

 which I have specimens from Messrs. Tulasne, but it is larger ; 

 the peridium is firm, and in old specimens does not contract 

 together with the central mass ; the spores not rose-coloured, and 

 perhaps rather longer. There is besides no mention made by 

 those gentlemen of the presence of filaments projecting from the 

 walls, and they themselves sanction me in considering it as un- 

 described. It approaches also to H. memhranaceum, Vitt., but 

 differs in several respects from it. I am the more induced to keep 

 it distinct, as I have the authority of Messrs. Tulasne, whose opi- 

 nion ought to have the greatest weight, that the species of hypo- 

 gseous Fungi are really more numerous than might at first be sup- 

 posed. In this and other exosporous truffles, spicules (sterigmata) 

 are not formed first, as is the case in the higher Hymenomycetes, 

 but the sporophores give off* the spores immediately. I do not 

 mean to affirm that there are no exceptions to this, but I have not 

 myself observed any.

Oblong, |ths of an inch in diameter, externally slightly to- 

 mentose, pale orange-red, fleshy, but by no means deliquescent, 

 rootless ; peridium thin, at length rugulose, within minutely cel- 

 lular ; substance of a beautiful orange-red ; cells hollow, clothed 

 with obtuse bisporous sporophores and slender cystidia : the cells 

 are also traversed from wall to wall by slender, occasionally 

 branched threads. Spores subelliptic, strongly echinulate, sup- 

 ported on short but distinct sterigmata. 



I have seen but three specimens of this species, communicated 

 by Mr. Stephens in three successive years, which is perhaps one 

 of the most beautiful of the group to which it belongs. The co- 

 lour is very vivid, exactly like that of a fine carrot. ^¥hen dry it 

 communicates a lemon-coloured stain to the paper in which it is 

 preserved. 



It is undoubtedly congeneric with Hydnangium carneum, of
