2. Sesia Berkeleyi (Sacc.)

 Dacdalca Berkeleyi Sacc. Syll. Fung. 6: 381. 1888. 



This species was described from specimens collected on pine 

 stumps near Gainesville, Florida. The fruit-body is larger than in any 

 other American species and the surface is only slightly tomentose, 

 becoming glabrous with age. The margin is much lighter than 

 the surface, being tawny-orange in color and contrasting vividly 

 with the dark umber of the older growth. It is also more porous 

 than most species of Sesia, the tubes rarely becoming more than 

 sinuous, though it is sometimes lamellate in parts of the tropics 

 where the fruit-body grows quickly. The only specimens at hand 

 are those collected by C. G. Lloyd in Florida and by Smith i n 

 Nicaragua and Mexico. 



3. Sesia striata (Sw.)

This species was the first of two plants listed by Swartz in his 

 Prodromus under the genus Agaricus, the second being Schizo- 

 phyllum alncum, also common in Jamaica. The brief description, 

 " A. acaulis, convexus ferrugineus pitbesccns, margine Integra, 

 lamcllis altcrnis intcrruptis cincrcis," is, as usual, much amplified 

 in his later work. 



Specimens from Mexico, still to be seen in the Fries herbarium 

 at Upsala, were described by Fries as L. protracta, a name which 

 has been generally assigned in Europe to a very different plant. 

 Fries also called some of the Mexican collections of this species 

 L. umbrina. 



Sesia striata is quite abundant on decaying wood in various 

 parts of tropical America, as the following partial list of specimens 

 will show: Colombia, Baker; Nicaragua, Smith; Honduras, Wil- 

 son 200, 276 ; Mexico, Smith; Cuba, Underwood & Earlc joj, 

 7 jo, 7JO, 1526, 1562, Shafer ; Jamaica, Underwood j+o, Earle 82,
