“Veðráttan” had 44 p.c. more precipitation, and July even 108 p.c.
more than the normal. In July all stations had I/2 to 2/2 times the
normal precipitation. These facts afford a likely explanation of the
early and rich fungus flora in 1935.
Of the fungus flora later on, in the year 1937, I am not able to
give any information. Nor can I state what time of the year the real
fungus-season is. The literature gives no information on this subject.
According to Poul Larsen, Fungi of Iceland, which
includes all the previous occurrences of fungi in the country, the north-
eastern and northern parts of Iceland seem to be much richer in larger
fungi than south-western and southern Iceland. But this, I am sure, is
not right. At the beginning of August 1935, for instance, I visited
Laugarvatn in the south-west country and here investigated the fungus
flora on a mountain slope covered with underwood (I had only a few
hours at my disposal). I found a greater number of species of the larger
fungi than I had found in other parts of the country (cp. list of fungi
