Callipodium aureum VerriU, sp. nov. 



Plate V, figure 23. 



Corallum yellow, encrusting, consisting of crowded, elongated, tubu- 

 lar corallites, united nearly to their summits, thus forming a corym- 

 bose cluster, with an uneven surface. 



The verrucfe in the central parts, w^here most crowded, project but 

 slightly above the surface and are rather large, rounded, and distinctly 

 eight-rayed in contraction. Some of the lateral verrucse project about 

 •10 inch. CcBnenchyma thickened, very spiculose, its surface and that 

 of the verrucse granulous. Color, in alcohol, bright orange-yellow. 



Height '5 of an inch ; breadth 1 ; diameter of verrucae about -08. 



Spicula bright golden yellow, similar in form to those of the pre- 

 ceding species, but larger, and with longer and more slender branches 

 or rays in the star-shaped forms. The larger sjjindles are mostly 

 rather stout, blunt, with distant, very prominent, large warts, which are 

 spinulose at summit ; they are often in-egular or lobed, and some are 

 rather slender. The star-shaped sjiicula have mostly three or four, 

 sometimes five or six, rays or branches, which are mostly unequal and 

 irregular, but usually considerably elongated and often slender, 

 smooth at base, but covered at the ends with a cluster of rough warts 

 or spinules. Irregular, roughly warted clubs and double clubs, nearly 

 as large as the spindles, also occur sparingly. Irregularly formed 

 spicula of various shapes, but with very prominent warts, are frequent.
