ON XYLARIA AND ITS ALLIES. 
157. Xylaria tuberosa (S plueria tuberosa , Persoon in “ Gaudichaud’s 
Voyage,” p. 180). 
Clavulis elongatis, glabris, apice compressis, ramosis, basi 
tuberoso. 
On rotten wood (?) Sandwich Isles. 
“ Intermediate between X. hypoxylon and X. bulbosa the radical 
tubercle is oval or oblong.” 
Specimens in Herb. Paris are sterile, except for the bulbous 
base, would at once be referred to X. hypoxylon , of which it is pro- 
bably only a form. 
158. Xylaria furcellata, Berk, in Herb. 
Stromate erecto, aurantio, supra bi-vel tri-dichotomo-furcato ; 
ramulis abbreviatis, obtusis, sub-clavatis, cinereis ; stipite erecto, 
tenui, aequali,' vel ventricoso, radicato ; peritheciis ignotis. 
The Neilgherries, India. 
A very marked, but imperfect species, about 2 inches high, the 
branched apex scarce half an inch across. 
159. Xylaria xanthiceps, Berk, in Herb. 
This again is a minute corticolous species of which only conidia 
are developed. The small clubs are tipped with yellow. 
161. Xylaria hystrix, Berk, in Herb. 
This is merely a fasciculate, erumpent condition of some species 
in its young and sterile state, and cannot be described. 
162. Xylaria Carteri, Berk, in Herb. 
Globosa, stipitata, atra, nitida in. diam.), intus fusca. 
On wood. Bombay. 
This also is evidently a species of Phylacia , whether that genus 
represents any condition of Xylaria or not. 
163. Xylaria ramulosa, Berk. ( Sphceria ramulosa , Schwz.). 
This has every appearance of being a species of Phylacia — 
internally it is chiefly brown, there are no perithecia, and we have 
seen no spores. 
On bark. Surinam. 
Arrangement. — It only remains for us now to subjoin an 
amended arrangement of the species under the same four groups 
as proposed originally by Fries, and adopted by Saccardo. It may 
not be wholly egotistical to affirm that our facilities for becoming 
practically acquainted with a vast number of species have been 
great, and from this experience we have been enabled to determine 
more accurately their affinities than could be done from descriptions 
alone. The subdivision containing species with a discoid base has 
not commended itself to us for adoption, since it is by no means a 
permanent character, varying according to the hardness or softness 
of the matrix. Almost all, if not all, the specimens growing on 
hard wood expand at the base, so as to secure a firmer attachment, 
whereas when the wood is soft the base is more or less penetrating. 
Both conditions may be observed in a good series of Xylaria 
hypoxylon.
