ing into at length crowded, short branchlets, which are now 

 deficient below, and the finally thickened podetia quite naked 

 (these conspicuously "beset everywhere with stalked, pale, pitted 

 cephalodia) ; apothecia terminal ; smallish to middling-sized ; 

 soon globular. Spores from fusiform soon acicular, 4-8-pmri- 

 locular ; and varying also greatly in size, from about 30 much 



exceeding 100 mic. in length, and from 3 to 6 mic. in width.

e Th. Fr. 1. c. The examination of my numerous specimens 



of this stock, from South America, Polynesia, Australia, and 

 Asia, leaves me without doubt that the earlier, presumably 

 larger conception of the species by the first describers is clearly 

 the natural one ; and should be returned to. Dr. Nylander has 

 indeed already (I. c.) reduced the new species of this group 

 proposed by Dr. Th. Fries ; as the latter author, for his part, 

 has well disallowed Nylander's discriminations based on the 

 differences in constitution of the cephalodia. The species (as 

 here received) is much the noblest of all; and as might be ex- 

 pected from its geographical range, varies into not a few marked 

 forms, from less than one to more than five inches in height, 

 and more or less tufted and branching ; with no little diversity, 

 as has been noted, in the spore-measurements ; but is always 

 distinguishable by the strigose podetia, to which it owes its 

 name ; its soon globular apothecia ; and its curious cephalodia. 



A specimen of the present species in Herb. Taylor, is 



marked " North America, Mr. J. Bradbury"; and Dr. Fries 

 finds specimens, in Herb. Swartz, of the var. macrocarpum, 

 Bab., which are said to have been collected in North America, 

 by Menzies ; but both references must be considered doubtful. 



2. S. coralloides, Fr. ; podetia smallish, rather compressed, 

 densely tufted; for the most part digitately- divergent ; much 

 branched especially above, smooth and naked below ; the more 

 or less scattered phyllocladia grayish- white, passing into digi- 

 tately divided, corallinoid, finally crowded branchlets ; (cepha- 

 lodia sessile, warted, soon bluish-gray;) apothecia commonly 

 smallish, lateral, and often heaped; but occurring now also
