Abstract：Eleven species of the genus Rigidoporus from China have been found and a key to them is given．Among
them，Rigidoporus furcatus is new to China．Descriptions and ilustrations of the new record are also provided．
Key words：Rigidoporus furcatus；lignicolous and poroid fungi；taxonomy
1 Introducti0n
Rigidoporus Murrill was first described by Mur—
ri11(1905)．It is characterized by pore and eoncolorous
surface，monomitie to pseudodimitic hyphal system，
simple-septate generative hyphae，mamnfillate cystidi—
oles，and subglobose to globose spores(Ryvarden，
1 9 93)．Eleven species in the genus have been reported
from China up to now(Dai，l996，2009；Cui et a1．，
2009；Yu et a1．，2008)．
During our study of the wood-decaying fungi in
Changbai Mountain Natural Reserve，we found an in—
teresting species new to China，Rigidoporus furcatus．
In this paper，an ilustrated description of R．furcatus
according to our material is given。and a key to the Chi—
nese species of Rigidoporus is also presented．
2 Materials and Methods
The specimen studied was collected from Chang—
bai Mountain Natural Reserve。and is deposited at the
herbarium of Institute of Applied Ecology，Chinese A—
cademy of Science(IFP)．The microscopic characters
were made from slide preparations stained with Cotton
Blue and Melzer’s reagent，under Nikon E60O micro—
scope，anatomica】details were drawn by the Nikon
drawing tube．KoH stands for 5 potassium hydrox—
ide，IKI stands for Melzer’s reagent。and CB is the ab—
breviation of Cotton Blue．( 一 一acyanophilous，CB+

noid． In presenting the variation in the size of the
spores，5 of measurements were excluded ftom each
end of the range，and are given in parentheses

spore length(arithmetic average of al spores)，W —
mean spore width(arithmetic average of all spores)，Q
=variation in the L／W ratios between the specimens
studied(quotient of the mean spore length，and the
mean spore width of each specimen)，n= number of
spores measured from given number of specimens．
