the border of Lule Lappmark), Jörn (Västerbotten) and Selsjön 
(Ångermanland). 
The lakes Vassijaure and Torneträsk being situated at 
about 68'/? lat. and near the tree limit, and having a compa- 
ratively low average temperature on account of the perpetual 
snow and glaciers on the surrounding Alps, I had expected to 
find the hymenomycetal flora of that region very scanty. To 
my surprise, however, it was found to be rather the reverse. 
Not only the whole birch-zone but also the region above the 
tree limit right up to the perpetual snow abounded with fungi. 
I must add, however, that this is true only with regard to my 
first visit (1909); the next year (1910) the fleshy fungi were 
rather scarce, and thus I learned that the frequency of these 
fungi here as elsewhere depends very much on the quantity of 
rain falling in due time. The year 1910 was abnormal in being 
more than usually dry during the greater part of the summer. 
Some of the genera were comparatively less represented 
than others. So for instance I saw but one species of Amanita 
(vaginata)', two of Lepiota (granulosa and amianthina) one of 
Armillaria (mellea), five of Tricholoma (album?, grammopodium?, 
1 Several varieties: white or whitish, livid, melleo-ochraceous. Common 
even above the tree limit, especially the whitish or livid variety. 
? At Björkliden and the adjacent side of Nuolja. — Just the species 
illustrated in FRIES” Ie. sel. t. 43. fig. 1, to which Trich. stiparophyllum and 
Trich. raphanicum seem to be synonyms. The spores are ovate or nearly oval, 
often oblique and l-guttate, 6—7 X 4—4!/, v. 
* Of this species I saw a white variety at Palnoviken. — Such a variety 
is found on several places in Sweden, for instance Norrbo in Helsingland, 
Stockholm, Rydbe in Upland (Hamner), Lidingö (TÖRNGREN). Ljusterö, 
Danderyd and Salem (G. RoMmELL) in Södermanland, Bedarö (SANDEBERG), 
Ödeshög in Östergötland and Hjo in Västergötland (C. TÖRNGREN). In 
Monogr. I p. 93 FnrEs mentions the occurrence of a »varietas omnino alba» 
of T'rich. grammopodium, and it may be supposed that he alludes to this plant. 
It is, however, not hygrophanous and as it seems to be constantly distinct 
and easily recognisable, I think it would be suitable and convenient to have 
a separate name for it. In my notes and in the herbarium I have suggested 
the name Tr. pubifolium, alluding to the projecting cystidia (50—100X 12—16 v., 
obtusely subfusiform, ventricose etc.) which render both sides of the gills 
quite velutinous under the lens, at least in the young state — a character 
which belongs also to the allied species. — The habit reminds one of Clitocybe 
tornata in FRIES” Ic. sel. t. 51. f. 1. and of Trich. cnista Bres. Fung. Trid. I t. 48 
and Fungh. mang. t. 31, but it can hardly be T'rich. cnista (misspelling for 
cnissa?) either of FRIES or of BRESADOLA, as the smell is neither that of roasted 
flesh nor mealy, but rather »mucidus». 
Though generally slender (stem 6—10X'/2—1'/2 em.), thinner and 
smaller (pileus 4—9 cm. broad), often umbonate and not allied to T'rich. gam- 
bosum, it is sometimes confounded with that species by beginners when col- 
lected simultaneously, the time of occurrence ranging from May to September. 
The color of pileus is generally white, as Rep. 364, 66, 67, 68 (Repertoire de 
Couleurs publié par la Société Francaise des Chrysanthémistes, 1905), but in
