We rather suspect, however, that Hydnum corrugatum, a very rare plant of 

 Europe, is the same species. Hydnum pulcherrimum does not belong in the section 

 Merismus, where Fries first placed Hydnum corrugatum, but to Apus, as it is found in 

 Hymen. Europae. Fries' plant, of which small specimens are found at Kew and Upsala, 

 probably grew in an abnormal position. (Cfr. Sverig. Svamp. t. 16.) 



STEREUM. 

 Stereum unguliformis. 



NOTE 114. Pileus flat, linear-cuneate, 2 cm. long, 2-5 mm. wide, tapering to the 

 base, the apex of the broader specimens cut into 4-5 segments. Color pale, white when 

 fresh no doubt. Hymenium surface even white. Spores 2%-3x6-7 straight, hyaline, 

 smooth. Cystidia none. 



This little species belongs to Section 9 of the Stipitate Stereums. Its nearest 

 affinity is Stereum cyphelloides. 



Stereum australe. 



NOTE 115. Pileus sessile, pubescent with a brown or grayish tomentum, zonate 

 with glabrous, brown, bay zones. Hymenium cinereous when dry, reddish brown when 

 wet. Basidia forming a compact layer in which are imbedded dark-colored bodies, "lac- 

 tiferous ducts." Cystidia none. Spores 4x6, hyaline, smooth, with granular contents. 



This is a tropical species of Stereum, apparently frequent, but which we have 

 not found named in the museums of Europe. It has been confused with the common 

 Stereum lobatum of the tropics, or Stereum fasciatum, which is the same thing. It was 

 so confused in our Letter No. 46 as "Stereum lobatum with cinereous hymenium." The 

 upper surface is exactly the same as Stereum fasciatum or lobatum, and the texture and 

 size are the same, but it differs in having lactiferous ducts, and "bleeding" when the 

 hymenium of a fresh specimen is bruised. It is closely related to Stereum spadiceum and 

 Stereum sanguinolentum. 



Recently we found this same plant, that reaches us from Madagascar, in Southern 

 United States (Florida). It does not occur with us except in the extreme South. We 

 have no name for it in American mycology, though we think it has been confused with 

 Stereum fasciatum, but not by Schtreinitz. 



Mr. Henri Perrier de la Bathie sends us three collections. 



Stereum affine. 



All of this collection with lateral stipes. 



Stereum lobatum. 



A most common plant in the tropics. 



Stereum surinamense. 



Part of this collection is funnel shape, part petaloid, which would indicate that 

 it will be difficult to maintain this as a species distinct from affinis, as we thought when 

 we wrote our pamphlet. 



Stereum Mellisii. 



A fine collection of a characteristic species. The hymenium is velutinate with 

 cystidia, hence it is a "Lloydella" for those who use this name. Leveille and others con- 

 fused it with Stereum affine. 



THELEPHORA. 

 Thelephora radicans. 



The genus Thelephora (true) is quite rare in the tropics, and as shown by this 

 collection, specimens vary much as to form. Thelephora acanthacea is an old name for 

 this species, and we think Ceylon specimens referred to Thelephora dentosa by Berkeley, 

 and inaccurately cited by Saccardo as the type, are probably the same. The type of Thele- 

 phora dentosa from Cuba is different.
