humile‘, multiforme’, rutilans*), three of Pleurotus (ulmarius’, 
conchatus’, serotinus®), none of Psalliota, none of Hygrophorus", 
the sunburnt state sometimes varying into pallid or creamy, as Rep. 325. 
The gills are white and crowded. The spores are white, ellipsoidal, grumous 
or l-guttate, spuriously asperulate, 9—12  5—6 vu. while the spores of Trich. 
gambosum are small, 4'/,—6 3 v (not as stated by some english authors). 
* At Abisko and Björkliden. I am not quite sure, whether the speci- , 
mens I found do really belong to T'rcholoma humile, though LINDBLAD many 
years ago referred thither similar forms found at Stockholm. The form I 
mean differs both from PrRsoon’s and from FRIES” description in several 
respects and especially in the gill color, which at last becomes dirty reddish, 
almost as Rep. 308 a, thereby reminding of Pluteus. It is no doubt allied to 
Trich. humile, Trich. grammopodium, Trich. melaleucum, Tr. arcuatum and 
Tr. brevipes, having about the same spores and cystidia, but the limit of Trich. 
humile FR. is still unclear to me and seems to be rather vague. 
5 This species was found along the railway only, but here it quite fre- 
quently grew in clusters, especially in the neighbourhood of the scientific 
station, where this plant and Naucoria myosotis probably were the most abun- 
dant fungi in 1909. It was noticed also at several railway stations, for in- 
stance Elfsbyn, Mellansel, Selsjön, cn my return the same year. In 1910 I 
scarcely saw it at all except a small cluster at Riksgränsen. At first I supposed 
this plant to be identical with one occurring at Stockholm which has been 
referred to Trich. tumulosum and which has globose spores (5—6—7 v. diam.), 
just as Tricholoma conglobatum (as understood by BRESADOLA in Fungi Trid. 
I. p. 27) and Clitocybe decastes (as understood by von Post) and Clitocybe 
fumosa etc. But the lapponian species, though apparently allied to all these, 
differs in having ellipsoidal spores (7—-8 X 4—5 v), and as it seems to agree 
tolerably in this respect with Tricholoma pes capra var. maultiformis (as under- 
stood by MassEv in COOkE, Illustr. t. 946), I have named it Trich. multiforme. 
Whether it is quite identical, however, either with MASSEY's or with SCHZEFFER'S 
plant of that name I am unable at present to decide. At all events I would 
object to call it »pes capre», as it has no more likeness to the feet of a goat 
than to the moon or anything else. — The color of my plant is much darker 
than Massey’s illustration, and the margin of the pileus is sometimes channelled 
as in Paxillus involutus.. The diameter varies say from 1—10 cm. 
As this species seemed to be confined to the immediate neighbourhood 
of the railway, one might suspect that its distribution to these regions should 
be due to the more frequent communications and transport of material and 
animals connected with the railway. The same might possibly be said of 
Clitocybe opaca (probably not distinct from Clit. cerussata), which grew at 
Katterjokk in a place, which served as a stable for horses during the construc- 
tion of the railway, and of Volvaria speciosa, which was found growing on rich 
soil at Stenbacken and Torneträsk stations. 
* Only at Kalixfors. 
4 7 On Betula at Björkliden, Kopparäsen and Pälnoviken. — The spores 
seem to vary from globose (4—5 v. diam.) to ellipsoidal-globose (5—7 X 4—5 v). 
> On Betula at Torneträsk station, Bergfors and Kalixfors. — Spores 
subeylindrical, 9—12 x 4 v. This plant occurs also at Stockholm, sometimes 
quite abundantly, on trunks of Betula and Sorbus, more seldom on Salix. 
I am not quite sure that it is identical with Burr. t. 298 and 517 O P, neither 
do I know what FRIES called it. From his statement that Pleur. pulmonarius 
grows on Betula and Sorbus one might suspect that my plant belongs to that 
species. It differs, however, both from FRIES” Icon. t. 87. f. 2 and from his 
description (the pileus being excentric and not »exacte lateralis»). At any 
rate my plant has nothing to do with Panus torulosus, to which FRIES considers 
his P. conchatus »nimis affinis». It is also eagerly eaten by vermin, which, 
according to FRIES, Panus conchatus should not be.
