 372 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Isabella-color (melleus of 'Chromotaxia'), cup-shaped, at length 

 flattened and disk-shaped, externally hairy; hairs olive-ocher 

 under the microscope, granular incrusted, cylindric, 300-400 

 X 4^-6 fjL] basidia clavate, 25-30 x 6-8 /x, 4-spored ; spores hyaline, 

 even, broadly ellipsoidal, 13 x 8 /x. 



Fructifications 1-1 ^ m^i- broad. 



On Quercus. Texas. 



The type is scanty, consisting of three fructifications, but 

 these fructifications are in fine condition and present well the 

 characters of the species. C. texensis now impresses me as more 

 closely related to C. Ravenelii than I observed when studying 

 the specimens of both in Kew Herbarium. The fructifications 

 of C. texensis are the melleus of Saccardo's 'Chromotaxia' and 

 the hairs are of a little greater diameter and have larger incrust- 

 ing granules than those of C. Ravenelii, but the spores and 

 basidia are very similar in form and dimensions in both species. 



Specimens examined: 

 Texas: Wright, 3779, type (in Kew Herb.). 



i8. C. mellea Burt, n. sp. Plate 19. fig. 12. 



Type: in Burt Herb, and in U. S. Dept. Ag. Herb. 



Fructifications closely gregarious, sessile, Isabella-color, spher- 

 ical and with margin inrolled in the dried state, sometimes 

 obconic, externally hairy; hairs granular incrusted, baryta- 

 yellow under the microscope, cylindric, 80-100 x 3|-4 n; hy- 

 menium even, whitish or pale olive-buff; basidia clavate, 12-16 

 X 6 m; spores mostly colorless but some pale baryta-yellow, even, 

 broadly ellipsoidal, 5-6 x 4-4| fx. 



Fructifications about |-| mm. high and broad. 



On rotten wood of Salix nigra. Louisiana. December. 



In the specimen upon which the description is based, the most 

 of the fructifications are about I mm. high and broad and are 

 distributed on the rotten wood at the rate of about 200 per 

 square centimeter. Rarely a short stem-like base is visible when 

 the fructifications emerge from the bottom of small crevices 

 between the fibers of the wood, but the fructifications are gen- 

 erally sessile. The species is intermediate between Cyphella 

 and Solenia but is included in the former genus because the fruc- 

 tifications do not arise from a common subiculum and are more 

 globose than in Solenia. The description of C. mellea suggests
