its similarity to the former— a genus of Algee. This led me 
to investigate some of the names which Saccardo himself 
admits. He allows without hesitation Libertella Desm. and 
Libertiella Speg and Roum ; Licea Schrad., and Lisea Sacc. ; 
Dichaena Fr. and Dichlaena D. and M. : Pleospora Rabh. and 
Phleospora Wallr. ; Entoloma Fr. and Entyloma D. B. ; 
Riessia Fres. and Reessia Fisch. and Eriosphaera Reich, and 
Eriosphaeria Sacc. Whether or not these are too nearly alike 
depends upon the taste and pronunciation of those who use 
them. To one using the English pronunciation, Licea and 
Lisea are indistinguishable. Besides these he admits many 
which are very much alike, but more defensible, as Arthrobo- 
tryum and Arthrobotrys, Urospora and Urosporium. He re- 
tains Antennaria Lk. in spite of Antennaria Ga;rtn., and even 
gives under the genus Marasmius the sections Collybia and 
Mycena, although there are the genera Collybia and Mycena 
in the same family. 
As regards specific names : he necessarily admits many 
which are very similar as pulvinula and pulvinulata, flavus 
and flavidus, etc. In a large genus, new specific names are 
rather hard to get and one ought not to be too sensitive. 
But are not the following too nearly alike : Puccinia penstem 
onum. Lev. and P. pentstemonis Pk ; P. schileana Speg. and P. 
scheliana Thuem; P. scleroteoides Mont, and P. sclerotioidea 
Cooke .? The following in Vols. \\\. and IV. are certainly in- 
defensible : Phoma pini C. and Hark, and P. piniSacc; Phyl- 
losticta viticola Thuem and P. viticola Sacc. and Speg. Zygo- 
desmus ochraceus Corda and Z. ochraceus Sacc, Cladotrichum 
fuscum Poeuss and C. fuscum (Grev) Sacc; Cercospora fumosa 
Pewz. and C. fumosa Speg. These and some others in the two 
volumes mentioned have been corrected, but in such out of the 
way places that very few would notice them. Those in Vol. 
III. are corrected in a note at the close of the index ; those in 
Vol IV. in a similar note mixed in with corrections of typo- 
graphical errors. For this reason I have given them. The 
following from Vols. V. and VI. have not. as far as I can find, 
been corrected : Polystictus stereoides Fr., and P. stereoides 
Berk., Fomes calignosus Ces., and F. calignosus Berk., Clava- 
ria cervina B. & C, and C cervina Sm., Polystictus cinerescens 
Schw. and P. cinerescens Lev., Stereum concolor Jungh., and 
S. concolor Berk., Clavaria coronata Schw. and C. coronata 
Zipp., Cyphella ravenelii B. & C. and C. ravenelii Sacc. 
This last he substitutes for C. fulva B. & C. to avoid C. fulva 
B. and Br. But the worst of all is in the genus Polyporus 
where there is, No. 303, Polyporus armeniacus Berk. Engl. 
Flor. V. 147. and also No. 215. P. armeniacus Berk. Hook.
