54 Thirty-second Report on the State Museum. 



PlNUS MITIS Mx. 



Specimens of this pine and of the scrub-pine, Pinus inops, have been received 

 from Mr. JV. L. Britton, who found them growing on Staten Island. This 

 makes six species of pine known to belong to the State. Unfortunately neither 

 of the specimens was accompanied by flowers or cones, from which I infer that 

 they do not fruit, and that the existence of these two species within our limits 

 will not be long continued. P. inops is also said to occur on Long Island, 

 but I have seen no specimens from that locality. 



Juncus Canadensis Gay, var. subcaudatus Engelm. 



Ditches along the railroad. South Corinth. Aug. 



The weak stems and spreading panicles give this variety an appearance 

 quite unlike that of the more common one, var. coarctatus. 



Trisetum molle Kunth. 



Cliffs near Central Bridge. June. 



Aspidium spinulosum Svxtrtz. 



Fertile specimens of the dwarf form known as var. dumetorum were found 

 on the Catskill Mountains. They are glandular-hairy and therefore should 

 be referred to the recently -proposed species, A. Am&ricanum Dav. The 

 typical A. spinulosum, as limited by Mr. Davenport, occurs on the Adiron- 

 dack Mountains. 



Botrychium ternatum Swartz, var. obliquum Eaton. 



The dwarf form of this variety with the sterile frond about one inch broad 

 and long and the whole plant three or four inches high was found at South 

 Corinth. 



Botrychium simplex Hitch, var. subcompositum Lasch. 

 Lewis's Bluff near Oswego. Rev. H. Wibbe. 



Bryum elongatum Dicks. 



This rare moss occurs on Slide Mountain, one of the highest peaks of the 

 Catskills. 



AGARICUS C^lSAREUS Scop. 



This species was found at G-ansevoort growing in a circle about forty feet in 

 diameter. About one-fourth of the circumference of the circle was unoccu- 

 pied by the fungus in consequence of the encroachment of a cleared field. In 

 the American form of the species the stem is .rather slender and equal or 

 slightly tapering upward. I have not seen it " subventricose " as required 

 by the description. 



Agaricus Americanus Pk. 



This Agaric usually grows in grassy places or on lawns, but fine specimens 

 were found the past season growing in a large tuft on an old stump. The 

 lamellae are much narrowed behind and somewhat reticulate ly connected. In 

 the fresh state the whole plant is white with the exception of the scales of the 

 pileus.
