L. ROMELL, HYMENOMYCETES OF LAPPLAND. 3l 
Of this species which generally has a pink tinge here and 
there, especially at the margin, there exists a pallid or creamy 
variety without such reddish tint. "This variety, which is rather 
frequent at Stockholm both on coniferous and deciduous wood 
and which I collected also at Jörn (on a trunk of Pinus silv.), 
is found in the east part of Torne Lappmark by C. P. Lastraprus 
and is mentioned by FRIES in Hym. Eur. p. 575 under Polyp. 
nitidus, with which it has nothing to do. BRESADOLA, to whom 
I sent specimens of this creamy variety many years ago, referred 
it to Mer. crispatus. And so it is named also by SOMMERFELT 
in his herbarium. TI doubt, however, that it is the true M. cris- 
patus FR., which is unknown to me (no authentic specimen 
having been saved so far as I know). In BLYTT's herbarium 
this same variety occurs under the name Mer. porinoides, sug- 
gested by BLYTT and approved by FRrES. A specimen so named 
by Fries in the Kew herbarium belongs, however, to M. 
molluscus. 
PERSOON'S Mer. serpens is identical with Mer. corium FR. 
Xylomyzon crustosum PERS. belongs, however, to M. serpens 
Fr. (The »tubercula sat magna» noted in Myc. Eur. II. p. 
34 are but perithecia of a Pyrenomycet on which the Merulius 
is growing.) 
Mer. tremellosus. 
On rotten trunks of Betula at Pàlnoviken and Kalixfors. 
Spores allantoid, 4—4 '/, x 1—1 '/, u. 
Solenia. 
S. villosa. 
On bark and wood of a rotten trunk of Betula at Bjórkliden. 
White, cylindric, about 1 mm. high, under the lens pulve- 
rulent or minutely pubescent. Spores globose, 5—6 w diam. 
S. anomala. 
On Salix (and Betula) at Nuolja, Abisko, Stordalen and 
Jebrenjokk. 
Spores oblongo-ellipsoidal, 7—9 x4— 5 wu.
