ON HYMENOCHAETE AND ITS ALLIES. 
By M. C. Cooke. 
The genus Ilymenochcete was established by Leveill^ for the 
reception of all those species, previously included in Stereum, which 
bore on the Hymenium coloured rigid setae. We alluded to this 
genus when writing of Peniophora, and proposed to enumerate the 
species which had come under our observation. The following are 
all the genuine species we have examined : — 
* MESOPUS. 
1. Hymenochaete reniformis, ( Fr.) , Lev. Ann. Sci. Nat., V. 1846, p. 151 
In Brazilian specimens, setae attenuated to an obtuse apex, *07 
to *1 mm. long, and from '014-02 mm. diameter at base. 
var. damaecornis, Lev. 
Hymenochaete damaecornis , Lev. Ann. Sci. Nat., v., 1846, p. 151. 
In Cuban specimens, setae long and slender, *1-*12 x *01 mm. 
In St. Domingo specimens, setae more robust and acute, *05- *06 
X *012-*015 mm. 
Evidently the setae are very variable, and profuse in all the forms 
in this species. 
St. Domingo, Cuba, Venezuela, Brazil. 
** APUS. 
2. Hymenochaeter ubiginosa, ( Schr.J , Lev. Ann. Sci. Nat. 1846, p. 151. 
Stereum rubiginosum, Fr. Hym., p. 641. 
Setae long and slender, *1 x '005 mm. 
Europe, U. States, India, Tasmania. 
3. Hymenochaete tabacina, (. Fr.),Lev . Ann. Sci. Nat. 1846,2?. 151. 
Stereum tabacinum , Fr. Hym., p. 641. 
Setae robust, *07 x *012-*014 mm., sometimes *08 X ‘015 mm. 
Europe, Arctic America, U. States. 
Stereum striatum , Fr., sometimes quoted as of this genus, has 
no setae, and is not a Hymenochaete. 
4. Hymenochaete Boltoni, ( Sacc.J 
Stereum Boltonii , Sacc. Michelia, i., p. 239. 
Setae clavate, attenuated at the base, •Q7-*08 x ’Ol-'Oll mm., 
smaller in resupinate form. 
Europe. 
5. Hymenochaete crocata, ( Fr .), Berk. 
Stereum aocatum , Fr. Hym., p. 641. 
Set» robust, *08 x -012 mm. 
Europe, United States. 
6. Hymenochaete rheicolor, (Mont.), Lev. Ann. Sci. Nat. v. (1846), 
p. 151.
