Table I. White spores.
Table II. Red and pink spores.
Table III. Ochraceous spores.
Table IV. Dark purple and black spores.
NOTE.
In using this table the student should first ascertain the color of the
spores of the specimen under investigation. This will determine the
particular table to be applied to its further examination. If, for
instance, he finds its spores to be white, he will know that Table I.
is the one to be consulted. Turning to that table, he should recall the
place of its growth, its habitat. Now, suppose it to have been found
growing on a stump, he will, by looking at the first column, Habitat,
of Table I., be informed that it must be one of the four genera named
in the column with the heading "On Stumps." Let him then examine its
"gills." If he finds them to be "adnate," he will be assured that it
must be an "Armillaria," as no other genus is shown in the column as
growing "on stumps" and which has gills that are adnate. But to make
assurance doubly sure, he may proceed further to discover whether the
specimen has also the ring called for in column headed "Ring.
