132 NEW YORK STATE MUSEUM 



lorn a hydrophilum, but from both, the species is separated 

 by the color of the lamellae and spores. A new description follows. 



Psilocybe conissans n. comb. 

 Clitopilus conissans N. Y, State Mus. Rep't 41 164; 42:45 



Pileus fleshy but thin, broadly convex becoming nearly plane, 

 glabrous, hygrophanous, pale chestnut or watery ferruginous and 

 striatulate on the margin when moist, pale alutaceous or pale buff 

 and sometimes slightly rugose when dry, flesh whitish; lamellae 

 thin, close, rounded behind, adnexed or rarely adnate, bay verging 

 to dark purple or liver color; stem equal, rather slender, firm, 

 glabrous, hollow, curved or flexuous, white, veil none; spores 

 vinaceous, elliptic, .0003—.0004 of an inch long, .00016-.0002 broad, 

 (8-10 IX long, 4-5 fj. broad). 



Cespitose on or about the base of deciduous trees. Catskill and 

 Adirondack mountains, also at Gansevoort, Saratoga co. Septem- 

 ber and October. Cystidia occur sparingly on the lamellae. 



Collybia lacunosa Pk. 



In New York State Museum Report 26, page 51 this plant is 

 described under the name Agaricus (Tricholoma) la- 

 c u n o s u s . Its texture is too tough to permit its reference to the 

 genus Tricholoma and it is here placed in the genus Collybia as a 

 better place for it. It is a pretty little golden yellow mushroom 

 inhabiting decaying wood. It is neither common nor plentiful. 



Crataegus bissellii Sargent 



A small shrub whose flowers have pale pink anthers soon fading 

 to pale yellow or whitish was found near Staatsburg, Dutchess co. 

 and referred to this species. A similar shrub but having flowers 

 with bright red anthers occurs in North Greenbush, Rensselaer co.j 

 As the anthers of the flowers of C. bissellii are described as 

 either pink or rose purple the North Greenbush shrub is also re-j 

 ferred to this species. 



Cypripedium arietinum R. Br. 



Near Hague, Warren co. Mrs E. Watrous. This is a rarej 

 species in our State and it is becoming more scarce from year to] 

 year. It is therefore gratifying to add this new locality to those] 

 previously known. Mrs Watrous sends both flowering and fruitinf 

 specimens.
