38 Thirty-third Annual Report of the 



Cheirospora botryospora, Fr. This species occurs with us on the 

 beech, Fagus ferruginea, and the water beech, Carpinus Americana, 

 Iu Europe it occurs also on the ivy. 



Puccinia linearis, Ph., On Calamagrostis Canadensis . Copake. The 

 name being preoccupied it is changed to Puccinia striatula, Pk. 



Uromyces solida, B. & C. Living leaves of Desmodium rotundifolium. 

 Newburg. The name of this species proves to be inappropriate and 

 the description very imperfect if we may rely on authentic specimens 

 received from Dr. Curtis. It is scarcely possible to identify the species 

 satisfactorily from the published description. The spores are not 

 always "compact, " but often quite lax. Neither are they always 

 " obovate, " but generally ovate or elliptical. The rough or ver- 

 ruculose epispore is a noticeable feature, yet it is not mentioned in 

 the description. It is not surprising, therefore, that the species has 

 recently been republished under a new name, Uromyces Desmodii 

 Thum. 



Roestelia lacerata, Tul. This fungus was recently detected by Prof, 

 D. S. Martin growing in abundance on the living leaves of apple trees 

 at Rogers Rock near Ticonderoga. An allied fungus, Mcestelia 

 cancellata, has also been found to attack the fruit of the quince. 



Peridermium decolorans, Ph. This is- considered by Baron Thu- 

 men in his " Blasenrost Pilze der Coniferen " to be a variety of 

 Peridermium abietinum. 



Peronospora alta, Fchl. Living leaves of English plantain, 

 Plantago lanceolata. Verona. 



Sphgerella nigrita, Che. This is not specifically distinct from 

 Splmrella spleniata, 0. & P., according to specimens received from Mr. 

 Gerard. 



NEW YORK SPECIES OF AMANITA. 



" Spores white. Veil or volva universal, at first continuous distinct 

 from the cuticle of the pileus. Hymenophorum distinct from the stem. 

 All terrestrial." Hymen. Eur op. p. 17. 



The Agarics which are grouped under the subgeneric name Amanita 

 are distinguished from all others by their white spores and their univer- 

 sal veil distinct from the pileus. In the subgenus Volvaria there is a 

 similar veil or volva, but the spores are rosy or pinkish-colored. By 

 some authors the species of these two subgenera have been united un- 

 der the common name Amanita, but even in this case it was found 

 convenient to separate them into two sections, depending on the color 

 of the spores. Some mycologists have regarded the species of Amanita 

 as worthy of generic distinction, and have separated them from the 

 Agarics as a distinct genus. But by those species whose volva is evan- 

 escent they approach so closely to other subgenera that it is difficult to 

 maintain this position unless we also raise the other subgenera to the 

 same rank. The differences between the subgenera are so slight that 

 this has not seemed advisable to the most eminent mycologists ; and 

 yet the species of Agarics are already so numerous that it is very diffi- 

 cult to find appropriate unoccupied specific names for the new ones
