It is necessary also to handle the specimens with the greatest care to
avoid leaving finger marks where the surface of the stem or cap is
covered with a soft and delicate outer coat, especially if one wishes to
photograph the plant, since rubbed or marked places spoil the plant for
this purpose.

Also a little careless handling will remove such important
characters as a frail annulus or volva, which often are absolutely
necessary to recognize the species.

Having collected the specimens, they should be properly placed in the
basket or collecting case. Those which are quite firm, and not long and
slender, can be wrapped with tissue paper (waxed tissue paper if they
are viscid or sticky), and placed directly in the basket, with some note
or number to indicate habitat or other peculiarity which it is desirable
to make at the time of collection.

The smaller, more slender and
fragile, specimens can be wrapped in tissue paper (a cluster of several
individuals can be frequently rolled up together) made in the form of a
narrow funnel and the ends then twisted. The shape of the paper enables
one to wrap them in such a way as to protect certain delicate characters
on the stem or cap.

These can then be stood upright in the small
pasteboard boxes which should occupy a portion of the basket. A number
of such wrappers can be placed in a single box, unless the specimens are
of considerable size and numerous. In these boxes they are prevented
from being crushed by the jostling of the larger specimens in the basket.

These boxes have the additional advantage of preserving certain
specimens entire and upright if one wishes later to photograph them.
