Friesia IV, 1-2

- 62-
mon, umbo darker brown to almost sepia, edge pale, incurved, scales
clay color to dark tawny olive or paIe sepia. Gills rather crowded,
narrow (up to 4mm broad), almost free, paIe yellowish when young,
soon bright buelethorn brown to tawny olive. Stipe 3-6 X 0,2­
0,6 cm, terete, solid, faintly hollow when old, in some specimens subbulbose,
at first pallid nearly to the base which is olive bistre, soon
flushed nearly to apex with this dark color, and even turning darker
when old, densely pruinose, obscurely striate. Flesh in cap and stem
firm, whitish with spermatic smell. Spores (8,0)8,5-10,0(11,5) X
5,0-5,6(6,1),u, elliptic, oblique in side view, thickwalled. Basidia
4-spored. Cheilo- and pleurocystidia 45-60 X 12-18 u , mostly
crested, walls 2-3,u tbick, often brownish ; caulocystidia similar
or more slender, 12 X 70 u .
Gregarious, several flocks on a small area. Oct. 8. a nd 18. , 1948 .
(2543, 2585).
The material has been compared with American exsiccata of
I . atripes (1166, 1306 and 1445, Cheboygan Co., Michigan, leg.
M. Lang e). As given in the original description (vide Kauff­
man (1924» the spores of I. atripes are somewhat shorter, 7­
9,5 X 5-5,5,u. In 1306 we find them still shorter, 7-8 X 5--6,u,
while in 1166 they are in accordance with the present find. The
cystidia of the American collections correspond to the data given
above, while H e i m (1931) for the only European find up till then
(from Languedoc) finds them similar in size, but very few crested
ones. Even if the microscopical characters seem somewhat variable,
the species is very well characterised macroscopically by the dark,
pruinose stem and the white, firm flesh.
No other Danish records are known.
3. Inocybe Langei f. bispora J. E. Lange The microscopicaI
characters were found in good accordance with the original description,
the majority of the spores measuring 10-12,5 .X 5,8­
6,6 u ; some few smaller spores between, 8-9,u long, are possibly
born on 4-spored basidia. Cheilo- and pleurocystidia 45-55 X 13­
16 u , thickwalled, mostly crested; caulocystidia similar or more
slender, more pointed, several of them smooth.
Like the plant depicted by J. E . Lange (L c.) most specimens
in the present find were more slender than the typical form. Oct. 18.,
1948 (2587).
