these, and there are others, do not occur in the north of Hants, so 
that the mention of soil as well as form, with other details, should 
enter into our definitions. ) 
Such a proposal does not seem a difficult one to carry out. County 
lists where they exist might be examined and the matter tested. If 
these lists are at present too imperfect, someone, from what is already 
known, might take the subject and follow it up. Our Annual 
Meeting would form a good occasion for comparison. . 
Fungus forays are apt to assemble and disperse, and facts known 
perhaps to a few escape permanent record. The point I would 
emphasize is, do Fungi, the larger forms more especially, conform 
to geological conditions ? The amount of moisture and temperature 
doubtless have a predominant influence in the erowth of these plants, 
but may not the chemistry of the soil have an importance of which 
at present we know so little in the prevalence of Fungi in certain 
areas: light soils 1 foot below surface are 1° warmer than air, heavy 
soils 1 foot below surface o°2 warmer than annual mean temperature 
gf the air.” 
To those who are on the watch, the occurrence of particular Fungi 
year after year in the same places has been remarked over and over 
again. [hey do not appear with the same regularity as the arrival 
of the flowering plants, they are more casual and uncertain ; but the 
species sooner or later, usually, if not this season then the next, come 
up in the old places. Being so perishable, passing away many of 
them in so short a time, makes the matter one demanding pretty 
close attention. Still, it does seem not at all an impossible aim to 
attempt; probably an additional stone might be added to the 
accumulating heap of knowledge that has been slowly and patiently 
gathered during the last few years of the century, of a curious and 
interesting study. 
Our list of Hants’ Fungi, as here printed, reaches 580 species, 
about 30 found in the Forest have not yet been found except in the 
South. The district most closely examined is the Grange Park as a 
centre, lying between Alresford and Micheldever.
