„They are both correct, however, and the common form on beech 
in France.” (Lroyp. Mye. Note 35. p. 469) These specimens are of 
no value as a type of this species. Undoubtedly, they do not belong 
to PersoON’s collection. They must have got among them by mistake. 
We find no original label; and in box 415 there is a label „Suri- 
name.” Evidently BRESApOLA does not seem to agree with Lroyp’s 
opinion: in tbe collection of tropical Fungi, we find a specimen, 
(in box 6, white) identical with those in boxes 415 and 417, with 
a note of BRESADOLA „Fomes surinamensis BRES. n. sp.” t) 
It is a pity there are no specimens of PERSOON, for it seems to 
me that there is some confusion in the nomenclature of these forms. 
Persoon, in the Myce. Eur. IL. p. 80, mentions: 
92. Polyporus fomentarius, the type; further: 
d. applanatus. 
y. stratosus and says: „Obs. Forsitan nonnullae aliae adhue 
existunt varietates, imo subspecies, magnitudine, colore plus minusve 
dilutiore et pilei superficie diversa, ad sequentem (i.e. igniarius) 
transeuntes, quo eum saepe commutatur.” 
Of these forms, we find in PERSOON’s herbarium, only specimens 
of Polyporus fomentarius > applanatus (box 393) labelled by him. 
It is Fomes applanatus WALER. „a very common species now 
known as Homes applanatus, for it is no variety of fomentarius as 
PERSOON thought” (Lroyp. Myc. Note 35) Further we find (in box 
274) two specimens, labelled by PeRSOON „Boletus fomentarius L.” 
This is not fomentarius at all but a typical igniarius. Probably he 
wrote this label about the date his Synopsis was published. In this 
work Persoon puts these different forms together under the name 
„Boletus fomentarius”’: „Sequentes fungos in Obs. Myc. 2. p. 2. ut 
distinetas species quidem proposui, verum summam ob affinitatem 
eos pro eonsilio, quod hoe in libro cepi,‚ ad interim ut subspecies 
et varietates enumerabo.” 
Fomes fulvus (Scor.) Bres. see Fomes pomaceus. 
Fomes fusco-purpureus BOUDieR see Fomes torulosus. 
Fomes igniarius. 
It is quite uneertain what LiINNAEUs meant by Boletus igniarius. 
„Persoon et Fries donnèrent à Vignarius sa sienification”’ (LrLoyp. 
Mye Note 95). It is therefore of importance to find a number of 
specimens under this name in PersoonN’s herbarium and to discover 
that they do represent the plant now known as Fomes igniarius. By
