" The Fungi 4 of Our Common Nuts and Pits" is the title of an 

 interesting and important paper recently contributed by Dr. C. E. 

 Fairman to the Proceedings of the Rochester Academy of Science. 

 Both saprophytic and parasitic fungi are included among the hun- 

 dred or more species listed. About thirty species and one genus 

 are described as new. The six plates are unfortunately rather 

 poor, but doubtless serve their purpose. 



Silver-leaf disease, caused by Stereum purpureum, occurs on a 

 variety of trees and shrubs in England, the hyphae of the fungus 

 being always present in the stem and roots of plants that are at- 

 tacked, but never in the leaves. Infection takes place through 

 wounds. There is a false silver-leaf disease, apparently not due 

 to fungous attack, which must be carefully distinguished. See 

 Bintner in Kew Bull. Misc. for 1919. 



I am sending under separate cover some specimens of Colostoma 

 Ravenelii which I collected on my farm near Conway, Kentucky. 

 The plants were growing in a clay bank along a wooded roadside 

 where the soil had been disturbed within a year or two. The farm 

 lies between the blue grass and the foothills. I had never seen a 

 Colostoma before and was wonderfully interested in the find. The 

 collection was made September 6, 1921. — Bruce Fink. 



A fine specimen of what appears to be the rare Stereum peta- 

 lodes Berk, has recently come in from Las Ninfas, Cuba, collected 

 there by Brother Hioram in midwinter. Professor Burt, to whom 

 a part of the specimen was sent, writes me : " I presume it must be 

 this species, as you determined. I have not seen the authentic 

 specimen of this species at Kew, but should I ever cross the water 

 again I have noted this specimen for comparison with the original." 



The correspondence of Schweinitz and Torrey, the two domi- 

 nating figures in American botany during the early part of the 

 nineteenth century, has been collected and published by C. L. 

 Shear and N. E. Stevens as a memoir of the Torrey Botanical 

 Club, dated July 16, 192 1. There is also included a list of the
