SECTION 3. 



Stipitate, with a mesopodial 01 lateral stipe. Smooth, bright color when fresh, 

 yellow in one species, bright purplish-red in another. 



STEREUM AURANTIACUM (Fig. 538). Pileus mesopodial 

 infundibuliform, or spathulate with lateral stipe, both shapes found 

 sometimes in same collection (as shown on Montagne's figuies), but 

 usually the collections are either all mesopodial or all pleuropodial. 

 Smooth, minutely silky, striate, the base of the stem with a yellowish 

 tomentum often forming a little disc on the host. Color of dried 

 plant fresh, uniform, yellow, but my collection notes in Samoa give 

 the hymenium surface as bright sulphur yellow, upper surface pale 

 yellowish white. Stipe pale, almost white. Old specimens lose the 

 bright color of fresh plant and become brown.

Stereum aurantiacum. 



I think there is but one yellow, stipitate Stereum in the tropics, 

 although spathulate and infundibuliform collections appear quite dif- 

 ferent. Montagne and Spegazzini both claim they are the same 

 species, and a collection we have from Madame Anna Brockes, mostly 

 infundibuliform, a few spathulate, bears out this view. Persoon 

 described it as petaloid. We think the position of growth has much 

 to do with the form. 



The types of Stereum aurantiacum both at Paris and Leiden 

 are not surely this plant, but more probably Stereum affine. They are 

 old and discolored, but Persoon's color description does not refer to 

 affine, hence I have taken the name in the sense of Montagne's and 

 Berkeley's more recent specimens, and apparently from the descrip- 

 tion in the original sense. 



t ILLUSTRATIONS. Beautifully illustrated by Montagne, Voyage La Sagra, Plate 1 (not Per- 

 soon s Voyage Freycinet, as incorrectly cited in Saccardo's citation of Icones). 



SPECIMENS. Anna Brockes, Crixas, Brazil, mostly mesopodial; C. G. Lloyd, Samoa, all pleu- 

 ropodial. It was quite rare in Samoa. 



STEREUM HARMANDL Pileus spathulate, flabelliform, thin, 

 glabrous, peculiar puiplish-ied color. Stipe short, evidently growing 

 in the ground.
