given below). That Poul Larsen has only very few occurrences from
the birch copses at Borgarfjörður, e.g., is simply due to the fact that
he visited the copses in June, when the fungi had not yet developed.
In the copse at Laugarvatn I found about 20 species of larger fungi,
new for Iceland, and therefore I have no doubt that many new finds
may be made. All the birch and willow copses in Iceland ought there-
fore to be investigated during the ‘fungus-season’ which as mentioned
above sets in at different times of the summer, according to the weather
conditions.
What with the rich fungus flora in 1935 and the short time at my
disposal my investigation of the Icelandic fungi was naturally unsatis-
factory. Several species, particularly of the genera Galera, Inocybe
and Cortinarius had to be passed over. However, many species new
for the country were determined and described. The determination and
the description were made in the field from fresh material. The colours
were determined by comparison with colour charts; other macroscopical
characters were noted down in the field. On the other hand, only a few
microscopic characters were examined, and material, particularly the
spore-powder collected on cellophane, of all the species, was brought
back in alcohol or in dry condition, so that the microscopical characters
could subsequently be revised and fixed.
