Hydxaceae 



Hydnum aurantiacum Pk. Sept. Infrequent. Tolland, 

 Leal. Under Abies. 



Hydnum imbricatum Fr. Infrequent. Leal. 



Under pine and spruce. This agrees well both microscopi- 

 cally and macroscopically with material I obtained near Stock- 

 holm, Sweden. It is futile to refer this species to Linnaeus. 

 We have, therefore, the northern European plant in this country. 

 It is necessary, however, to use the highest magnifications in 

 examining the spores and basidia in order safely to segregate 

 the species which are somewhat similar externally, and to 

 possess good field-notes. 



Hydnum graveolens Dolastre var. Sept. Rare. Tolland. 

 Under conifers (pine and spruce). 



Hydnum repandum Fr. Sept. Infrequent. Tolland, Leal. 

 Lender conifers (pine and spruce). 



Hydnum scrobiculatum Fr. Sept. Infrequent. Tolland. 

 Under conifers (pine and spruce). 



Hydnum suaveolens Fr. (See Plate XXXIII.) Sept. In- 

 frequent. Tolland. Under conifers (pine and spruce). 



Hydnum Underwoodii (Banker) Coker. Sept. Frequent, 

 Leal, Tolland. 



Under spruce and fir. Three collections were brought. Its 

 superficial characters were not sufficiently striking in the older 

 and larger plants to indicate that we had something interesting 

 and doubtless we usually passed it by as H. imbricatum. When 

 it is younger and smaller in size, the teeth are short and the 

 description of Banker and Coker applies well. When it is larger 

 and more luxuriantly developed, the teeth are as much as 5 or 

 6 mm. long, and the surface of the pileus may become cracked- 

 scaly and imitate H. imbricatum. But the crowded, slender and 

 fragile teeth, and, to a smaller degree, the color of the plant, 

 separate it quickly from H. ijnbricatum.. Our larger specimens 

 compare well with Ellis, N. A. F., No. 926 {H. imbricatum), 

 and although Banker included this in his account of H. Under- 

 woodii {Mem. Torr. Bot. Club, XII: 148. 1906), his formal
