Hydiium geogenium, Fr. 



Woods. South Ballston. Aug. 



I am not aware that this rare and interesting species has before 

 been noticed in this country. According to Fries, the species is very 

 variable, so much so that some specimens might be referred to the 

 section Pleuropoda, others to Mesopoda, ind others still to Apoda, 

 to which the typical form belongs. 



Hydniim farinaceum, Pe7's. 

 Decaying wood of hemlock. Osceola. Aug. 



Grandinia granulosa, Fr. 



Dead bark of alders. Karner. Sept. 



A variable species, referred to Thelephora by Albertina and 

 Schweinitz, to Hydnum by Persoon, and to Grandinia by Fries. 

 Our specimens were whitish when fresh, but they become oohraceous 

 or snbalutaceous when old and dry. They are also rimose, thus 

 answering to variety rimosa Pers. 



Corticium puteanum, Fr. 

 Decaying wood in swamps. Guilderland. Sept. 



Corticium radiosum, Fr. 

 Decaying wood. Osceola. Aug. 



Corticium cinerascens, Berh. 



Dead branches of oak. Albany. Aug. 



Our specimens are resupinate. The hymenium when moist was 

 tubercnlose and of a dingy hue; in the dry state it is cinereous and 

 rimose. The spores are elliptical. 



Clavaria circinans, n. sp. 



Stem short, solid, dichotomoiisly or snbverticillately branched ; 

 branches slightly diverging or nearly parallel, nearly equal in length, 

 the ultimate ones terminating in two or more short acute concolo- 

 rous ramuli ; spores oehraceous. 



Plant 1 to 2 in. high, obconic in outline, flat topped, appearing 

 almost as if truncated, pallid or almost whitish in color, generally 

 growing in imperfect circles or curved lines. 



Under spruce and balsam trees. Adirondack mountains. Aug. 



Clavaria gracilis, Pers. 



Ground in open places, especially under brakes, Pteris aquilina. 

 Adirondack mountains. 



The typical form has the branches numerous, nearly straight and 

 slender, but forms occur in which they are thicker, more loose and 

 flexuous. Such forms approach C. Kanzei in appearance, but they
