REPORT OF THE STATE BOTANIST 1899 



855 



Cladonia papillaria (Ehrh.) Hoffm. 



Thin soil covering rocks. Minnewaska. September. Fine fertile 

 specimens were obtained. 



Cladonia mitrula Tuckm. 



West Shokan. August. This is the most northern station in 

 which I have found this southern lichen. 



Cladonia macilenta Hoffm. 

 About the base of an old stump. Minnewaska. September. 



Lecanora hageni Ach. 



Decorticated surface of hemlock trunk. Savannah. October. 

 The apothecia were very abundant, nearly covering the surface of 

 the wood in patches. 



Amanita rubescens Fr. 



This species is sometimes attacked by a parasitic fungus, which 

 arrests its proper development and usually causes it to appear like a 

 thick, white stem with no cap or only a very rudimentary, unex- 

 panded one. Specimens were found near Denning in which the host 

 plant had been so slightly changed that its identification was possi- 

 ble. When the parasite, which isHypomyces i n a e q 11 a 1 i s Pk., 

 develops an abundance of perithecia, it sometimes gives a slight sal- 

 mon hue to the surface of the host. 



Amanita frostiana pallidipes n. var. 



The typical form of this species, which is common in our cool 

 northern woods, has the pileus and annulus and usually the stem also 

 of a yellow color, that of the pileus sometimes verging to orange. 

 But in warmer and more open or bushy places forms occur in which 

 the whole plant is whitish, but in other respects has the characters 

 of the species. Sometimes the pileus is pale yellow and the stem and 

 annulus white. The warts are soft and flocculent, are sometimes 

 numerous and persistent and again are few or wanting. The form 

 with yellow stem and annulus and yellow or orange pileus may be 

 considered the typical form of the species, but forms having the 

 stem and annulus pale or white may be designated as variety 

 pallidipes.
