for it to be maintained as a species; according to BRESADOLA: „le 
premier à indiquer les points de divergence entre cette plante et 
Vigmarius, mais il Pappela fulvus de Soor.” (Myc. Note 35). As 
Lroyp observes it is preferable to call it Fomes pomaceus, because 
opinions are divided as to Fomes fulvus, whereas under the name 
Homes pomaceus PERSOON, we find good types in his collection. This 
after all seems to me of greater importance then the question of 
priority. 
Polyporus ribesius (in box 286) and Polyporus ribis. Myc. Eur. 
(good specimens in box 208) „as well known now as Fomes ribis.” 
Fomes rubriporus Qurer see Homes torulosus. 
Polyporus scoriatus. 
In box 354 a number of good specimens, labelled by PERSOON: 
„Polyporus scoriatus. Inventus ad basin trunci Mvonymi europaei’” It 
is the same plant that was was called by KALCHBRENNER Polyporus 
Kwvonymi as appears from a note by Lroyp: „Polyporus scoriatus is an 
unpublished name of PERSOON. KALCHBRENNER 1), who first deseribed 
the species supposed it to be closely allied to Polyporus Lomicerae: 
„Monente amico KALCHBRENNER praecedentis subspecies”’?) For 
SRESADOLA and Lroyd it is the same species as Fomes ribis „excep- 
ting the host.” It seems to me to be closely allied to Fomes con- 
chatus. 
Fomes torulosus. 
In PersoonN’s herbarium we find a number of specimens under 
this name. These are, as Lroyp says, the most interesting plants 
of the collection „car toute trace des recherches faites par lui à 
leur sujet a disparu des traditions même de la mycologie europé- 
enne.” (Myc. Note 55). Afterwards Boupter?) described it as Homes 
fusco-purpureus and gave a beautiful figure in his leones (Pl. 156). 
Qurrer®) described it as Fomes rubriporus. These names should be 
changed into Fomes torulosus; under this name PERSOONS) des- 
eribed the species and a number of good types are to be found in 
his ecolleetion, in box 183 and 207 labelled by PeRSOON:; also we 
find a large and beautiful specimen in box 409. In box 46 there 
is one labelled by PreRSOON „Boletus torosus.”
