Abstract：The knowledge of Gloeoporus in China is summarized，and three species in the genus have been found in
China．G．thelephoroides is newly found in China，it difers from other species in the genus by its effused-reflexed ba—
sidiocarps，pinkish cream pores and simple septate generative hyphae．The illustrated description of the species is giv—
en based on the C：hinese materials．
Key words：Gloeoporus thelephoroides；polypore；taxonomy；Hainan
1 Intr0duction
The genus Gloeoporus M ont．was established
in 1842 by the type species Polyporus conchoides
Mont．The most obvious characteristic Of this ge—
nus is the pore—mouths with continous hymenium
(Quanten，1997)．The species in the genus have a
monomitic hyphal system ，colored tube—layer and
allantoid basidiospores． Many species have been
transferred or described in this genus，but only 4
species were accepted by most mycologists(Ry—
varden & Johansen，1980；Nflflez & Ryvarden，
2001；Gilbertson＆ Ryvarden，1986)，and two spe—
cies were previously recorded in China(Zhao，
1998)．
During the study on wood—decaying fungi in
China，more specimens in the genus were exam—
ined，and G．thelephoroides(Hook．)G．Cunn．was
found from Hainan Province． Because this species
had not been recorded in the Chinese fungal flora
(Zhao，1 998)，in this paper we provided an illustra—
ted description of the species according tO our ma—
terials．In addition，two other species in the genus
from China were studied，and a key to the Chinese
species was supplied．

2 Materials and M ethods
The studied specimens are deposited at the
Herbarium of the Institute of Applied Ecology，
Chinese Academy of Sciences(IFP)．Anatomy was
studied，and measurements and drawings were
made from slide preparations stained with Cotton
Blue．Drawings were made with the aid of a draw—
ing tube(Cui et a1．，2007；Huang et a1．，2006)．
The microscopic routine used in the study followed
Yuan(2004)and Yuan et a1．(2006)．In presenting
the variation in the size of the spores，the 5 of
the measurements at each end of the range are
shown in parentheses．The following abbreviations
are used：IKI-=negative in M elzer’s reagent，KO H
=5 potassium hydroxide，CB— Cotton Blue，CB
十 一 cyanophilous，CB一= acyanophilous，L：：=mean
spore length(arithmetic average of all spores)．W —
mean spore width (arithmetic average of all
spores)，Q=variation in the L／W ratios between
the specimens studied．n= number of spores meas—
ured from given number of specimens．

4 Discussion
Gloeoporus PZP户^ 0r0 dP5 is cha／acterized by
its effused-reflexed basidiocarps，slightly ochra—
ceous to pinkish pores，a monomitic hyphal system
with simple septate generative hyphae and allantoid
basidiospores．
Gloeoporus dichrous also has effused—reflexed
basidioearps，but differs from G．￡ ZP ^ or0 d s by
the presence of clamp connections on generative
hyphae．In addition，G．dichrous is a cosmopolitan
species，while G． P^ZP 0^rD Ps is a pantropical
species，distributed in tropical or subtropical areas．
G．taxicola has similar microstructure with G．
eZep^ Dr0 Ps，but its basidiocarps are resupinate
and its pores are reddish brown． Skeletocutis
amorpha(Fr．：Fr．)Kot1．&Pouzar also has pileate
basidiocarps，fl gelatinous hymenophore and allan—
toid basidiospores，but its hyphal structure is dim—
itic with clamped generative hyphae(Nflfiez，2001)．
