A PoLYPORE Parasitic on Twigs of Asimina 



This species, Inonotus amplectens, was first described by the 

 writer (Bull. Torrey Club 31:600. 1904) from specimens col- 

 lected by R. M. Harper on the Ocmulgee River near Lumber 

 City, Georgia, in September, 1903. The fruit-bodies were found 

 encircling living twigs of Asimina parviflora. 



There are now four other specimens in the herbarium of the 

 New York Botanical Garden. A collection was made on A. parvi- 

 flora at Rock Springs, Orange Co., Florida, on August 28, 1909, 

 by Mr. C. H. Baker, who stated that it was first observed by him 

 about 1904. 



Two collections were made by Mr. Baker on A. pygmaea in 

 August, 1909; one near McDonald and the other near Plymouth, 

 in Orange Co., Florida. He says that the fungus is peculiar to 

 Asimina, and that the twigs on which it grows usually appear to 

 be killed. 



When Dr. G. Clyde Fisher was in Florida recently, he col- 

 lected the same polypore on living twigs of Asimina angustifolia 

 at Gainesville, July 29, 1919, thus adding another specimen and 

 another host to our collection. 



This interesting fungus is now known from Georgia and north- 

 ern Florida, occurring on three species of Asimina: A. parviflora, 

 A. pygmaea, and A. angustifolia.

An Orange-colored Puffball 



Calvatia ruhroflava has been collected two past seasons in the 

 dahlia bed near the museum building of the Garden, but well- 

 developed specimens were not obtained until brought in by Miss 

 Eaton on August 22, evidently having grown from the same patch 

 of mycelium. This puffball, which is easily recognized by its 

 orange color, is very rare, although widely distributed in gardens 

 and other cultivated places. The species was first described by 

 Cragin in the Washburn College Bulletin for 1885, from spec- 

 imens collected in Kansas in October. The measurements given 

 in his description, which is copied below, are rather small, my 

 plant being 3]^ inches broad and nearly three inches high.
