L. ROMELL, HYMENOMYCETES OF LAPPLAND. 29 
M. lepidus n. sp. — Fig. 16. 
Resupinatus, mollis, laxe adhaerens, recens amoene auran- 
tius (Rep. 53, 55, 56) et merulioideo-gibberosus, siccus (fere) 
laevis et pulchre incarnatus (Sacc. Chrom. 16) vel subtestaceo- 
incarnatus (Rep. 63), subiculo albo, molli. Hyphae non fibu- 
latae, 3—4'/, v latae. Basidia 4-spora, 7—9 t. lata. Sporae 
erucaeformes (obovoideo-allantoideo-oblongae), 9—12 x4—5 p. 
On dead branches of Salix at Nuolja. 
This beautiful species was rare. And rare it is also at 
Stockholm, where I have met with it only once (on fallen bran- 
ches of Populus tremula, in April). EcGELAND has collected it 
at Christiania. 
Though habitually very distinct from Cortierum incarna- 
tum, especially in its fresh state, it is still perhaps rather allied 
to that plant and can easily be placed in the genus Corticium 
if preferred. 
M. molluscus — Fig. 18. 
On a rotten trunk of Betula at Björkliden and on wood of 
Pinus silv. at Kalixfors. 
Spores subhyaline, globose-ellipsoidal, 5—6 x4. Basidia 
4-spora, 12—20x4—7 y. Hyphae soft, fibulate, 2—6 t. 
broad. 
The color of this species is rather variable, in its fresh 
state often orange or about so, with paler margin, but not seldom 
dirty yellow (about melleous) or with spots of such dirty color, 
in dry state generally melleous or ochraceous, with or without 
a tinge of more or less orange. The »carneus» color stated by 
FRIES and others and shown in the right part of Icon sel. t. 193. 
fig. 2 must be rare, if at all existing. I never saw that color 
though the plant is well known to me, it being common at Stock- 
holm; but specimens exposed to the light have sometimes a 
shade in which a trace of carneus may perhaps be considered 
immixed. In the specimens found in Lappland, especially 
that from Björkliden, the delicate cobwebby margin is sulphu- 
rous. 
I use here the name »Mer. molluscus» as understood by 
Ros. Fries, KARSTEN and BRESADOLA, as the illustration above 
cited (viz. the left part of it) seems to endorse such interpre- 
tation. It must be added, however, that the name question
