TWO NEW rUNGl. 



this interesting subject, not only with European plants, but with 

 tropical ones also, the selection of types being governed by reference 

 to habit, habitat, colouration of congeners, &c. ; it might also 

 prove instructive to ascertain under what conditions, if any, white 

 varieties will produce the colour of their normal fellows. 



TWO NEW FUNGI. 



The Rev, M. J. Berkeley describes in the " Gardeners' Chronicle " 

 for Juno 17th (p. 785) two very interesting new genera of Fungi, 

 both from Africa, sent to him by Herr Kalchbrenuer. Their characters 

 are as follows : — 



1. Kalchbkenneka, Berk. — 

 Receptacle hemispherical, con- 

 fluent with the stem, giving oflf 

 numerous radiating nail-shaped 

 simple or forked processes, 

 between which the hymenium 

 is spread. 



K. Tuckii, Berk.— Volva 

 filled with fine gelatine, half 

 immersed in the soil, 1-^ inch 

 wide, 1|^ inch high, white, 

 minutely furfuraceo-floccose, 

 within slightly veined. Stem 

 4 inches high, fixed to the volva 

 at the base, fistulose, wider 

 above, clathrato-cellulose, pale 

 waxy yellow, slightly tinged 

 with red above. Receptacle 

 hemispherical, divided into 

 from 12-16 bright scarlet, nail- 

 shaped processes, which are 

 cylindrical or compressed 

 below, entire above or 1-2-fur- 

 cate, after the manner of the 

 thorns of CarissaArduini, Lam., 

 the colour of which remains in 

 the dried specimens, and be- 

 tween which is spread the even 

 olive-black stratum of spores. 

 Smell strong and extremely 

 disagreeable. Spores minute, 

 ovate, pellucid. 



Springing up after rainy, 

 thundery weather, and decaying 

 in the course of twenty-foru 

 hours, thisvery interestingplant 

 has occurred three or four times
