color of the species. Smaller specimens were found growing near 

 these but in a more exposed place. These had the usual color of 

 the species. 



Peziza (Mollisia) typhae Pk. 

 This name is antedated by Peziza (Mollisia) typhae 

 Cke. Though bearing the same name the two fungi appear to be 

 quite distinct. In the New York species the cups are superficial 

 and the disk is much paler than in the other and the spores are much 

 smaller. We therefore substitute the name Mollisia palli- 

 dior for Peziza (Mollisia) typhae Pk. in New York

Physarum lateritium (B. & R.) Rost. 

 Bark in woods. Lyndonville, Orleans co. Autumn. Scarce. 

 C. E. Fairman. The Lyndonville specimens differ from the typical 

 form in having the lime granules of the peridium and the nodules of 

 the capillitium yellow instead of red. 



Polystichum acrostichoides incisum (Gr.) Under. 

 Pound Ridge, Westchester co. July. Mrs E. S. Tomlinson 

 The specimen is a very broad one, the frond being nearly 6 inches 

 broad in its widest part. The fruiting pinnae are not abruptly re- 

 duced in size as in the ordinary form of the species. 



Populus balsamifera L. 



In the town of Sand Lake, Rensselaer co. there is an outlying and 

 unusually southern station of this northern tree, the balsam poplar. 

 The trees are few in number but they have existed there for many 

 years. Those bearing pistillate aments predominate, but staminate 

 aments are borne by at least one tree. The location is so far south 

 of the general range of the species that late frosts often kill the 

 early starting blossoms and prevent the development of fruit. Some- 

 times when this does not occur the crop of pollen seems to be in- 

 sufficient for the general pollination of the pistillate blossoms. Last 

 spring many pistillate aments were found with only three or four 

 fruit pods developed, the others having prematurely fallen. The 

 lack of proper pollination was probably the cause. 



The leaves on the older and less vigorous branches are somewhat 

 rhomboidal and pointed at both ends, but those on young and vigor- 

 ous branches are more ovate and broadly rounded or even truncate 

 at the base. Both kinds of leaves grow on different branches of
