Zusammenfassung: | In the process of studying the diversity of Xylariales in China, three species owning characteristics of Graphostromataceae were observed in China. Morphology of the described species with illustrations and their phylogeny based on regions of internal transcribed spacers (ITS), the second-largest subunit of the RNA polymerase II (
RPB2
), β-tubulin (
TUB2
) and α-actin (
ACT
) are provided. Two new species and one new record from China are identified. Morphologically,
Biscogniauxia glaucae
sp. nov. differs from
B. atropunctata
var.
maritima
,
B. citriformis
var.
macrospora, B. fuscella
and
B. mediterranea
by its stromata with raised margins, clear outlines, punctate ostioles openings and ascospores which are equilateral with broadly rounded ends, a straight spore-length germ slit on the more concave side, lacking appendages and sheathes.
Graphostroma guizhouensis
is identified as a new species based on the multi-gene phylogenetic tree.
Camillea broomeana
with scanning electron microscope description of ascospores is illustrated as a new record from China.
Cryptostroma
is proposed in
Graphostromataceae
based on molecular data.
Vivantia
is accepted in
Graphostromataceae
based on its morphological characteristics and
Nodulisporiurn
anamorphs which are similar to those of
Biscogniauxia
