abietino affine.” In the Mye. Eur. (LL p. 205) he still gives it as 
a seperate species but adds: „an mera Polypori (Boleti) abietini varietas? 
uti putatur.” 
9. Polyporus dolosus. 
In cover sub N°. 910, 23—513; 910, W3—518 and 910, 
265—523. lt appears from the Myce. Eur. that PeRrsOON supposed 
tbis form to be elosely allied to Polyporus abietinus. ) LLorp says: 
„Surely the same as abietinus and from PeRSOON’s remarks and 
labels it is evident he was somewhat of that opinion himself.” 
(Myce. Note. 35) Mouceor sends him a specimen (in cover, N° 910, 
265—513) with this note: „J'ai toujours regardé ee champignon 
comme état jeune du Sistotrema violaceum.”” Another specimen (in 
cover sub N°. 910, 265—518) is labelled by PeRSOON: „Boletus dolosus 
Mye. Eur. Sistotrema violaceum Syn. Fung. p. 5ol? sed pori fere 
toti integri nec laceri: specimine forsan nondum evoluto.” 
Polystictus argyraceus. 
Some specimeus, in cover sub N° 910, 262-952 and 910, 262 
— 054. According to LroyDp „it may be an exolete versicolor, as 
Fries refers it. (Fries Hym. Eur. 568 „Polyporus argyraceus Pers. 
Mye. Eur. 2 p. 73 est modo status exoletus, vernalis, corruptus.”) 
Indeed, with one of the specimens (sub _N”. 910, 262954) we 
find a remark of PreRrsoON: „An status vetustus B. wersicoloris?” In 
my opinion it is all Polystictus versicolor. 
Polystietus einnabarinus. 
Three specimens, in cover (N°. 910, 263 
SOON „Boletus cinnabarinus JAcQ.” 
It is Polystictus cinnabarinus as now well known (LLovyp). 
Polystictus lutescens. 
Formerly BRESADOLA considered Polystictus lutescens to be the 
same plant as Trametes hispida. It appears however from his notes 
in PERSOON’s herbarium (Jan. 1911) that he has changed his opinion. 
According to these notes (and also those of Lroyp) this name should 
disappear. 
We find rather a large number of specimens under this name, 
which belong to the following species: 
1. The specimen N° 910, 263838 labelled by PERSOON : „Polyporus 
lutescens var. flavescens.” ligured by Lroyp (Myc. Note 35 fig 334.) Accor- 
dine to Lrovp it is only a brown form of Polystictus hirsutus. We find

1) Myc. Eur. II p. 78.: „Ob summam affinitatem cum antecedente (= abietinus) 
hane speeiem hue retuli, quamvis sensu systematico melius ad genus Sistotrema 
pertineret,”?
