Mycologia 



A fresh young specimen of Ganoderma sulcatum Murrill was 

 collected by Dr. and Mrs. Pennell, November 22, 1919, on a trunk 

 of Sabal Palmetto on the Isle of Palms, Charleston County, 

 South Carolina. Several large specimens were seen at the time, 

 similar to one brought in from the same locality in February, 

 1916, by Dr. Small. This species was described in 1902 from 

 specimens collected in Florida by Mr. C. G. Lloyd. It seems to 

 be confined to the palmetto and is known only from Florida, 

 Georgia, and South Carolina. Mr. W. H. Long found it several 

 times in Florida. The single Georgia collection was made by 

 Mr. R. M. Harper in 1903 near Thalmann, in Glynn County. 



The nematode disease of wheat in Virginia is treated by F. D. 

 Fromme in Bulletin 222 of the Virginia Agricultural Experiment 

 Station under date of August, 1919. This disease is already 

 widespread in the state, being known from 33 counties. Its pres- 

 ence may be recognized by the wrinkling and distortion of the 

 leaves of the young wheat plants, by the abnormal appearance of 

 the heads, and by the occurrence of hard, brown galls in the heads 

 iti place of the grains of wheat. It may be prevented by the use 

 of clean seed and crop rotation. 



Ergot on Paspalum 



Last fall, especially during the latter part of October, ergoty 

 Paspalum was extremely common in the vicinity of Fayetteville, 

 Arkansas. Specimens were also received from other localities in 

 the state. The grayish-white sclerotia corresponded to the de- 

 scriptions of these bodies on this host genus. However, it was 

 not ascertained whether the fungus was Claviceps Paspali Stevens 

 & Hall or C. Rolfsii Stevens & Hall. Dr. F. L. Stevens, in 

 correspondence, writes that it is necessary to germinate the 

 sclerotia in order to determine the species of Claviceps involved ; 

 apparently the sclerotia of the two species are very similar and 

 the differences between the two species are only to be observed 

 in the fruiting heads which bear the asci.
