Abstract：During the reexamination of the Pertusaria specimens preserved in HMAS-L and NNU，2 species
new to China in this genus are added tO the Chinese lichen flora in present paper．
Key words：Pertusaria hemisphaerica；P．trachythallina；lichen taxonomy；China

The genus Pertusaria iS characterized by a
crustose thallus，hemiangiocarpous apothecia that
are often sunken in verrucae；the presence of a true
exciple；a hamathecium built of paraphysoids，
thick—walled asci；and one—celled，thick—walled，hya—
line ascospores． The chemistry of the genus is
complex(Archer，1993)．
Modern detailed studies of the genus Per—
tusaria in other parts of the world have been pub—
lished including monographs from portions of the
Old World(Erichsen，1936)，Japan(0shio，1968)，
North America (Dibben，1 9 80)and Australia
(Archer，1997)．
There was no study on the genus from China
before a new Pertusa ria species was described by
Krempelhuber in 1873．So far，83 Pertusaria taxa
from China have been reported in some scattered
literature(Zahlbruckner，1928，1930；Oshio，1968；
Wei，1991；Yu，1999；Aptroot＆ Seaward，2001)．
However．material available at that time was limit—
ed． During rechecking the specimens studied by
some of authors above，2 Pertusaria species are
founded new to China．

per were deposited in HMAS—L and NNU．
Both the dissecting microscope(ORIENT)and
fl compound microscope(Olympus)were routinely
used for all materials．Thin layer chromatography
(TLC．Culberson& Kristinsson，1 970；Culberson，
1 972)was used for the identification of the sub—
stance．Some terms of morphology and anatomy
are used after Dibben(1980)．
2．1 Pertuaria hemisphaerica (F16rke)Erichsen，
Hedwigia 72：85(1932)
Thallus lightly pale bluish grey to grey，medi—
um to thick；margins (prothallus) definite，dis—
tinct，white，zoned；upper surface smooth or uneven
to warted，lightly shiny；Isidium absent，but soradia
present，granular and concolorous with thallus．So—
radia often developing into confluent soralia，ca 0．3
～ 1．5 mm in diam，markedly convex，scattered to
fused．
Apothecia not seen．
Chemistry：Cortex K一，C一，KC一，P一；Medulla&
Soralia K一，C+ red，KC+ red，P一．TLC：lecanoric
acid or lecanoric and variolaric acids．
Habitat：Corticolous，rarely saxicolous．
Remarks：P．hemisphaerica is characterized
by bluish grey hallus，white and zoned prothallus，
concolorous soralia，and the chemistry．The species
is similar to both Ochrolechia subviridis and Per-
tuaria Zactea．But O．subviridis has dark green to
grey—white thallus． W hen growing on rocks P．
hemishpaerica resembles P．1actea in which both
thallus and soralia are white．
Distribution：Europe and China．
