ON XYLARIA AND ITS ALLIES. 
35. Xylaria escharoidea, Berk., must include also Xylaria piperi- 
formis , Berk. (131). Xylaria mutabilis , Curr., in Linn. Trans., 
and Xylaria flagelli formis, Curr. in Linn. Trans., which latter is 
only a sterile condition of his Xylaria mutabilis , as his own 
figures will show. The sporidia in all three species are absolutely 
identical. 
55. Xylaria Telfairii, Berk. should stand as synonyms of 
79. Xylaria tabacina, Kickx. ) Xylaria involuta, Klotsch, which 
is the other name, whilst 63 Xylaria Wrightii , B. & C., appears 
to present no specific difference. 
67. Xylaria acicula , Ces., according to specimen from Cesati 
does not differ from X. aristata , Mont. 
75. Xylaria cerebrina ( Fee.), is certainly an Hypoxylon with a 
coloured stroma, according to specimens in Herb. Paris. 
120. Xylaria Guepini , Fr., and 
Xylaria eupeliaca, Ces , can scarcely be regarded as the 
same species. 
133. Xylaria ianthino -velutina, Mont., and 
153. Xylaria Apeibce , Mont., as well as 
Xylaria moniliformis , Berk, in Herb., must be held to 
constitute one species, as Saccardo suspected. 
Although we are hardly prepared to expect that our suggestion 
would ensure Professor Saccardo’ s approval, we would transfer his 
Nos. 83 and 84 to the genus, or subgenus, Rhopalopsis , hereafter 
designated. 
Additions. — The following species are not included in the 
“Sylloge,” some of them never having been published. They 
are all described here, although some of them could not be included 
in any list except as if species dubiae,” such as Xylaria tuberosa . 
Their relationship to other species, as we comprehend it, will 
be indicated in the classified list at the close of this communica- 
tion. 
2. Xylaria australis, CooTce. 
Stromate clavato, nudo x f in.), sursum incrassato, obtuso, 
laevi, fusco, ex ostiolis mimitissimis obscure punctato, intus albido 
dein cavo ; stipite elongato (1^-2 in.) glabro, tenui (£ in.) nigri- 
cante ; ascis cylindraceis, stipitatis, sporidiis arcte lanceolatis, 
fuscis (-615 x *003 mm.). 
On wood. Endeavour River, Australia. 
Resembles very much the description of X. euglossa, Fr., but the 
sporidia are of a different form. 
10. Xylaria olobapha, Berk, in Herb. Kew. 
Stromate erecto, clavato, rufo, infra in stipitem brevem attenuato. 
Stipite tenui, glabro, sequali ; peritheciis globosis, atris, ostiolis 
punctiformibus, planis ; ascis cylindraceis, stipitatis ; sporidiis 
lanceolatis, rectis vel curvulis, fuscis ('02 -'022 x '0085 mm.). 
On trunks. Brazil, Mexico. 
Whole plant 2-2^ inches high, of which the club occupies half. 
Club 1 c.m. thick.
