97, as may be determined by comparison of the descriptions, and 

 is confirmed by the types at Kew. 



The study of numerous specimens of Steccherinum multifidum 

 (Kl.) at Berhn, Kew, New York Botanical Garden, and in the 

 writer's herbarium show the plant to vary considerably in the 

 degree of development of the hymenial ridges and teeth, and 

 always there is more or less interruption in the extent of these 

 features, so that many parts of the hymenial surface appear 

 nearly smooth. The margin of the pileus also varies greatly 

 from barely fimbriate to deeply laciniate. 



The plant appears to be of fairly common occurrence but is 

 confined to the region of the West Indies. 



Doubtful Species 



Hydnum decurrens B. & C, according to Berkeley, is based 

 on plants collected by Wright in Cuba and sent to Berkeley by 

 Curtis, Nos. 234 and 297. The specimens are at Kew and No. 

 234 is a fragment of little value. No. 297 is a good complete 

 specimen identical in every respect with specimens distributed in 

 " Fungi Cubenses Wrightiani," No. 346, as Hydnum decurrens." 

 The plants appear to be too near Steccherinum ochraceum 

 (Pers.). 



Hydnum plumarium Berk. & Curt. Grev. i : 97. 1873. Not 

 H. plumarium Berk. & Curt., Jour. Linn. Soc. 10: 324. 1869. 

 The type according to the citations of Berkeley is " 4936 Car. 

 Sup." The specimen at Kew marked " 4936 Hydnum plumarium 

 B. & C. Car. Sup. on Viburnum " appears to be a pale, perhaps 

 weathered, specimen of Steccherinum laeticolor B. & C, but the 

 material is too scanty to be of much value. 



Hydnum conchiforme Sacc. Syll. Fung. 6 : 458. 1888, was 

 proposed as a substitute for Hydnum plumarium B. & C. above 

 and hence is based on the same material as type.
