pureum. Cantharellus cibarius. Cantharellus clavatus (See Note 56). 

 Hydnum imbricatum.- Cyathus striatus. Polyporus griseus. Diatrybe bul- 

 lata, named by Mr. Weir. Mycenastrum Corium. Pleurotus serotinus. 

 Xylaria digitata. Trametes, unknown to me. 



Ganodermus Oregonensis, surely, but only an obese, horizontal form of 

 Polyporus lucidus. It has same color, surface, context, pores, and spores. 

 Trametes hispida, small pored form. Hydnum caput-ursi. Cantharellus 

 floccopus. Polyporus alboluteus. 



Hydnum aurantiacum. Notwithstanding this is fragrant, and the auran- 

 tiacum of record is "inodorous," I think we shall have to consider this a 

 fragrant form. Polyporus caesius? Polyporus picipes. 



Merulius squalidus, "purplish when young." I have collected this same 

 species in Sweden, characterized by a distinct purplish color ("incarnato," 

 Fries called it) which disappears entirely from the dried plant. It is very 

 close to lacrymans. Merulius molluscus. Trametes protracta. Finely de- 

 veloped. Polyporus. Evidently similar to fragilis and mollis in its general 

 .nature, white, turning red, but quite different in its spores, 3 1-2 x 7-8. 



Polyporus albidus. It seems to me exactly the same as European speci- 

 mens, where it is frequent on Pinus species. Seems more rare in this 

 country. Trametes variiformis. The first collection I have ever received 

 and the only time I have seen it excepting the types at Albany. It is not a 

 synonym and has little resemblance to Trametes serialis of Europe as er- 

 roneously compiled by Murrill. 



WHETSTONE, DR. MARY S., Minnesota: 



Stereum rufum as found in Fries, but the genus is not a good one for 

 it. Helotium citrinum. Hydnum aurantiacum. Daldinia concentrica. Dal- 

 dinia vernicosa. Boletinus porosus. Peziza occidentalis. Thelephora lacin- 

 iata. Polyporus gilvus. Hydnum nigrum. Thelephora palmata. Poly- 

 porus dichrous. Tylostoma campestris. A stipitate Scleroderma (See Note 

 57). 



Specimen unknown to me even as to genus. From its spores, I suppose, 

 it is a Thelephora, but in its habits, texture, and everything else, it is en- 

 tirely different from any Thelephora known to me. Polyporus albellus. 

 Tremella vesicaria. Polyporus obtusus (See Note 64). 



Ptychogaster ? Something unknown to me. Probably a conidial con- 

 dition of something. Has the general appearance of Ptychogaster albus 

 (cfr. Old Spec., p. 31), but I find no spores which are so abundant on 

 Ptychogaster. Polyporus nidulans. Stereum spadiceum. Lenzites saepi- 

 aria. Polystictus hirsutus. Helvella elastica. Cordyceps herculea. Young. 

 Irpex lacteus. Polyporus adustus. Lenzites trabea. Trametes hispida. 

 Not well developed. Lenzites confragosa. Fuligo septica. Tremelloden- 

 dron pallida. Thelephora multipartita. Scleroderma Cepa. Polyporus ob- 

 tusus (See Note 58).^Reticularia Lycopardon. Polystictus biformis, very 

 unusual, irpicoid form. 



WOULFF, E., Russia: 



Battarrea phalloidea. This is a rare species in Western Europe, known 

 from but one locality of France and from only a few of England. The
