A QUARTERLY RECORD OF CRYPTOGAMIC BOTANY 
AND ITS LITERATURE. 
ON XYLARIA AND ITS ALLIES. 
By M. C. Cooke. 
Having gone over the genus Xylaria , as represented in Sac- 
cardo’s “ Sylloge,” we have determined upon presenting the results 
in a form which may serve as a supplement to that portion of the 
volume. To the limitation of the genus in the work cited we have 
no restrictions to offer, but, accepting the limits as defined, we 
have some few additions to suggest, some emendations to offer, 
and a re-arrangement to propose. These will be considered under 
their respective headings. 
Measurements. — Annexed is a series of measurements of 
sporidia, obtained, as we believe, from authentic specimens, some 
in our own possession, others in the Paris Collection, and others 
in the Herbaria attached to the Royal Gardens, Kew ; those of 
Montagne, Leveille, and Berkeley being from specimens derived 
from the authors. Wherever there w^as no original specimen at 
our disposal we have accepted the Rev. M. J. Berkeley’s deter- 
mination. The Borneo specimens were communicated to us by 
Baron Y. Cesati. Although we have had access to 112 out of the 
153 species enumerated in the Sylloge, there still remain 40 of 
which we have no practical knowledge.
