ends, resembling an Umbelliferous inflorescence. Hymenium on 

 lower surface, even, white. 



This curious species is known only from the original collection, 

 Spruce, Brazil. 



STEREUM ANASTOMOSANS. Caespitose, the numerous 

 pilei dissected into narrow lobes, having much the appearance of a 

 Clavaria. Color reddish brown. Spores (abundant) are globose, 

 hyaline, smooth, 4 mic. 



This specimen only known from Wright's collection, Cuba. It 

 seems to have giown on branches. 



SYNONYMS. 



Thelephora dissecta, Guadalupe, Leveille = Stereum Hartmanni. 



Thelephora Harthmanni in Saccardo, misspelling of specific name of Stereum Hartmanni. 



SECTION 8. 



Erect, dendroid, with the form of a Clavaria. Hymenium amphigenous. 

 There are several species of Thelephora that belong in a similar section, but only 

 one known Stereum, and that one known from a single specimen. Other species 

 formerly classed as Thelephora have cruciately divided basidia and are now classed 

 either as a section of Sebacina or as a genus, Tremellodendron. 



STEREUM UNICUM (Fig. _ 555). Pileus erect, dendroid, with 



flattened branches. Color ferruginous, uniform. Surface velutinate 



with soft, projecting, colored hyphse. Spores un- 



t known, doubtless white. 

 This species is only known fiom a single speci- 

 men in the museum at Albany, collected in New 

 York thirty-five years ago. Professor Peck recently 

 told me that he never found but this single specimen, 

 and no one else has ever met it. It has the color of 

 the section Hymenochaete, but the setae are of a 

 different type entirely. Professor Peck (30th Report) 

 referred it to Thelephora speciosa, now classed in the 

 section Hymenochaete (see page 41), but the plant 

 has but little analogy to this plant of the American tropics. 



SECTION 9. 



Petaloides. Pileus spai'hulate, reduced to a stipe or stipe-like base. Stem 

 lateral. (Species that are usually infundibuliform, but take petaloid shapes, also 

 are classed in preceding section.) 



STEREUM CYPHELLOIDES. Very small (less than a cm.), 

 white, spathulate, smooth, reduced to a stipe-like base. Known at 

 Kew only from the types Cuba, but I have a collection from H. 

 Perrier de la Bathie, from Madagascar, that seems on comparison to 

 be the same. Notwithstanding its small size, it is an obvious Stereum 

 as to thickness and textuie.
