thin and brittle when dried. Cystidia, none. The microscope shows 

 a few minute, hyaline hairs on upper surface, which are not visible 

 to the eye. 



This is quite a frequent plant in the tropics, and numerous col- 

 lections at Kew and Berlin have been generally misreferred to Stereum 

 elegans, from which it differs entirely in its habits of giowth. It 

 grows singly or giegarious on branches and wood. I found it in 

 Samoa varying from an inch or two in diameter up to three or four 

 inches. However, I have not noted such large specimens in the 

 museums. There are specimens at Kew (referred to Stereum elegans) 

 from Afiica, Brazil, Australia, East Indies, West Indies, and Ceylon. 

 While Berkeley usually refeired it to Stereum elegans, a single speci- 

 men from San Domingo he called Stereum fulvo-nitens. Recent col- 

 lections from the Philippines are in error referred to Stereum Jung- 

 huhnii. 



SPECIMENS. While it is frequent in the museums of Europe, we have only our own collec- 

 tion from Samoa. 



Compare Stereum affine and Stereum malabarense in Section 9, similar plants as to color and 

 habits, but flabelliform as to shape.

Stereum Mellisii. 



STEREUM PERGAMENEUM (Fig. 545). This has very much the shape and 

 color of Stereum nitidulum, but differs in habits. It grows on rotten wood and has 

 no rooting base. It is best known from Rav. Exscc. No. 25, and, I think, has never 

 been collected by any one excepting Peters in Alabama. I can not be sure that 

 Stereum pergameneum is other than old, discolored specimens of Stereum diaphanum, 

 but it is so much daiker than any of my specimens oi diaphanum that for the present 

 I prefer to hold it as distinct. 



STEREUM MIQUELIANUM. This seems to differ from Stereum pergame- 

 neum as Ravenelii differs from nitidulum in being thinmr, more slender, and more 

 delicate species. It occurs in Brazil, and at Kew is named in mss. by Cooke, Stereum 

 Trailii. I have also a specimen from Rev. T. Gillet. Congo Beige. It grows on 

 branches and, according to Trail's collection notes, was "whitish when fresh." No 

 type of Stereuni Miquelianum was found by me in Montagne's herbarium, but 

 from locality, habitat, and description I have little doubt it is the same plant that 

 I saw at Kew.
