“A. Xylaria polymorpha group. Examples include X. anisopleura,
-X. bulbosa (PERS. : FR.) BERK. & BR.,- X. curta FR., X. feejeensis,
X. longipes NITS., X. obovata (BERK.) FR., X. polymorpha,
X. schweinitzii, X. tuberiformis, and probably, -X. castorea BERK.-
+ X. corniformis Some of these species can now be separated
on conidial and cultural features (ROGERS, 1983; 1984 a; 1984 b).”

NOTE: X. bulbosa and X. castorea removed at Dr. Rogers’ direction, as USA material under these names are, in fact, X. corniformis
“Xylaria longipes is closely related to X. polymorpha, from
which it is hardly distinguishable in the field, both species
exhibiting similar highly variable stromatal shape and corky‐
cracked surface. They are mainly separated based on different
ascospore size range and the conspicuously sigmoid germ slit of
X. longipes. Unlike what it is suggested by its name, the stromata
of X. longipes are often short‐stipitate to almost sessile. It seems
restricted to Acer pseudoplatanus, but X. polymorpha also occurs
on this substrate, which makes microscopic examination of
ascospores the only way to identify them safely.”
