OMPHALIA UMBELLIFERA, L. 



Not rare in the Adirondack mountains. Variety ahiegnus grows 

 on soft decayed wood of coniferous trees, and has a pale yellow 

 pileus. Variety alpinus grows among mosses and on muck soil 

 composed of decomposed vegetable matter. It usually occurs at 

 high altitudes. It was plentiful in June on the stmimit of Mt.

PHOLIOTA MYCENOIDES, Fr.

 pileus rugose. 



LENZITES SEPIARIA, Fr. 



A resupinate form, var. dentifera, occurs on spruce in the Adiron- 

 dack mountains, in which form the lamellae anastomose, and are 

 more or less toothed or lacerated, resembling an Irpex more than 

 a Lenzites. 



POLYPORUS VOLVATUS, Pk. 



This singular species develops in May and June in the Adirondack 

 mountains. When young it is slightly viscid. It is especially 

 subject to the attacks of insects. In July most of the specimens 

 will be found to be infested by them. 



CREPIDOTUS H.^RENS, Pk. 



Fine specimens of this rare species were found on ash and butternut 

 near Sprakers. The pileus is sometimes slightly floccose-squamulose. 

 The tough viscid pellicle is s sparable, and in drying the moisture 

 disappears from the disk first, from the thin margin last. 



HYDNUM GRAVEOLENS, Delast. 



A singular Hydnimi was found at Elizabethtown, in which the 

 pileus was very uneven and everywhere coated with a whitish 

 villosity or tomentum. It has the peculiar odor of H. graveolens, 

 to which species we have referred it as variety incBquale.
