CLADODERRIS TRAILII, (Fig. 524, p. 6) is for me only an excessively 

 papillate form of Cladoderris dendritica. The type form often develops a few 

 warts, as shown in Fig. 523 below. When these papillae are very numerous it becomes 

 Cladoderris Trailii. In the type specimen the warts are of the ordinary blunt form, 

 but in one specimen at Kew (Fig. 524) they are more slender. The hymenium folds 

 are typically those of Cladoderris dendritica, and is the only type of hymenium 

 folds found in the American tropics. The form of Cladoderris dendritica with very 

 numerous warts is much more rare than the ordinary form, with none or a lew warts.

CLADODERRIS ELEGANS (Fig. 525, p. 6). As to color, 

 variation as to form and stipe characters, and very often as to the 

 even, thick tomentum pad on the pileus, elegans is similar to den- 

 dritica, but elegans has the narrow folds of the hymenium densely 

 covered with papillae. In addition, Cladoderris elegans, as all the 

 Eastern types of Cladoderris, has a more rigid nature than those of 

 the American tropics. And the hymenium folds, while narrow, are 

 more the nature of those of Cladoderris spongiosa, and specimens 

 occur connecting it with spongiosa, rather than with dendritica. 



Cladoderris elegans originally from Java appears to be quite 

 frequent in the East in general, and specimens have been noted from 

 Java, Malay, Philippines and Mauritius. 



CLADODERRIS SPONGIOSA (Fig. 526, p. 7). Color pale, prob- 

 ably white when fresh. Pileus usually flabellifcrm, rarely infundibuli- 

 form, the upper surface even, spongy, with a dense, thick tomentum
