particular collection was mentioned by me in the Asa Gray Bul- 

 letin for December, 1899, under the heading 'A Truffle from 

 Maryland.' If this connection is not pointed out it may not be 

 known and confusion may arise. The specimens referred to in 

 the note as T. oligosperma Tul. are the identical specimens which 

 are described as the new species of Tuber in your article." 



Excellent specimens of Xanthoporia Andersoni (Ellis & Ev.) 

 Murrill were recently sent to the herbarium of the Garden for 

 determination.. They were collected on Salix nigra in Takoma 

 Park, Maryland, ]\£ay 5, 1920, by Hedgcock, Hahn, and Gravatt. 

 This interesting species was first described from Newfield, New 

 Jersey, where it was found by F. W. Anderson on an oak log. 

 It has since been collected on poplar in Indiana, on oak in Mis- 

 souri, and on elm or poplar in Ohio. The specimens recently re- 

 ceived add a new host and a new state to its distribution. 



Burt's eleventh paper on the Thelephoraceae of North America, 

 published in the Annals of the Missouri Botanical Garden for 

 November, 1919, includes Tulasnella, with 3 species ; Veluticeps, 

 with 1 species ; Mycobonia, with 2 species ; Epithele, with 2 

 species ; and Lachnocladium, with 10 species from North 

 Arnercia. The following are new or newly combined : Veluticeps 

 tabacina (Cooke) Burt, comb. nov. ; Epithele sulphur ea Burt, sp. 

 nov., on palmetto in Florida; Lachnocladium bicolor (Peck) 

 Burt, comb. nov. ; and L. erectum Burt, sp. nov., on dead wood 

 in West Virginia. The members of this genus are coralloid fungi 

 usually occurring on wood or soil rich in humus. They resemble 

 species of Clavaria, but are tomentose and leathery rather than 

 fleshy, and therefore inedible. The spores vary from hyaline to 

 ochraceous and from smooth to aculeate. Lachnocladium Miche- 

 ?it?n Berk & Curt, is our commonest temperate species, ranging 

 from Canada to New Jersey and westward to Missouri.
