man does not agree with me. It differs, as indicated above, and the 

 color is quite different. The cuticle is closely adnate, and does not 

 peel away as it does in the normal form. I once made in Kentucky 

 a collection showing the same difference as to color, but that collec- 

 tion had normal pores. I have never considered it 

 other than a variation of Favolus europaeus. 



FAVOLUS WHETSTONEI (Fig. 870). Stipi- 

 tate, with large, angular, thin pores decurrent on the 

 stem. Spores 4 x 10, hyaline, laterally apiculate. 

 Pileus surface white, with faint indications of the 

 reddish color of fresh Favolus europaeus. Based on 

 a single specimen from M. S. Whetstone, Minneapolis. 

 It is so different from the normal Favolus europaeus 

 that we hardly expect others to agree with us in re- 

 ferring it as a sport.

ISARIA BUNTINGII, FROM R. H. BUNTING, AFRICA 



(Fig. 87 1)/ The genus Isaria is supposed to be the conidial or pre- 

 liminary fruiting 

 stages of Cordy- 

 ceps. (cfr. Cordy- 

 ceps of Australasia, 

 pages 4 and 5.) 

 The perfect Cordy- 

 ceps is a subse- 

 quent develop- 

 ment. But four 

 large Isarias are 

 known to me on in- 



, sects or cocoons, 



i viz., Isaria farinosa 



j (Cord. Aust., Fig. 



! 613), Isaria atypi- 



| cola Japan (cfr. 

 Myc. Notes, p. 



, 568), Isaria gigan- 



1 tea Cuba, which 



i has never been il- 

 lustrated, and the 

 above from Africa. 

 We present a 



i photograph of Isa- 

 ria Buntingii, 

 which was made by 

 Mr. Bunting, and which tells the whole story as far as known. It 

 , differs from other species in having the fruit branches, forming a 

 capitate cluster at the apex of the stem. As will be seen, it grows 

 from cocoons buried in the fallen leaves. We hope Mr. Bunting will 

 favor us with specimens of the plant, and we particularly trust that 

 he will watch out for the subsequent (Cordyceps) clubs that no doubt 

 ; develop from the same host.
