There are no plants more difficult to preserve for an herbarium than the fleshy fungi, and yet my personal observation leads me to believe that there are many people who would be willing to undertake the task if they knew how to set about it; and there is no class of plants in which the assistance of the amateur may help the botanist more than in this, provided that, at the time of gathering a specimen, full descriptive notes are made of all the characteristics of the plant.

To aid one in quickly taking notes, it is well to have with one in the field some printed or written blanks. A convenient form is suggested by the following outline, which is the one used by the Boston Mycological Club :

Species Collected by No.

Locality Date

Collector'S Notes.

N.B.- When collecting, be sure to get the whole plant, base and all, uninjured; and to get young as well as mature specimens.

Note here at once the

Habitat.

On Tree (kind; dead or living). On Ground (kind of soil).

Place (wood, field, wet or dry, high land or low, etc.). Under and near what trees?

Manner of Growth.

Solitary, in clusters, troops, or caespitose [growing from one root]).

Character.

(Viscid, hygrophanous [transparent when moist], dry.)

Smell.

Taste.

Spores. Colour.

Note. - If the plant is perishable, sketch and describe it fully at once, and look 10 145

Fungi for the Herbarium for indications of spore colour. After the plant is described it may be dried in hot air (over a stove for instance) and preserved or sent in for identification.

Sketch the plant, indicating markings of cap and stem. Draw or trace a vertical section through the centre of cap and stem, indicating thickness of flesh; shape and attachment of gills; nature of interior of stem; position of ring, volva, etc. Do this also for a young specimen (button), showing whether the margin of the pileus is straight or incurved.

N.B. - f not life size, note dimensions.

When the characters vary with age or with moisture, note the changes.

Pileus { Shape (flat, convex, concave, umbonate [raised in the centre], {umbilicate [depressed in the centre], etc.).

Is it viscid when moist and fresh; tough, fragile, fleshy, membranaceous; smooth, floccose, scaly, silky, fibrillose; even, rough, wrinkled, furrowed? etc.

Is the margin entire, wavy, striate, inrolled, upturned, smooth, woolly, hairy, appendiculate? etc.

Colour and markings.

GillS. Shape.

Attachment (adnate, sinuate, decurrent, etc., ox free).

Are they distant or crowded, all of one length, branching or forked, connected by veins ?

Surface (smooth, powdery, marked in any way).

Colour (young and old).

Texture (thick, thin, brittle, etc.).

Margin (entire, wavy, scalloped, toothed, fringed).

With Boleti note colour, length, and size of tubes, shape and size of mouths, relation of pore surface to stem, etc.

Flesh. Consistency (firm, mealy, punky, etc.).

Colour (in general; just under skin; near gills or tubes).

Juice (taste and colour). Stem. Texture (tough, flexuous, fragile, fleshy).

Shape (tapering either way, straight or bent, swollen, etc.).

Exterior (cartilaginous, fibrous or not, etc.).

Colour and markings (striate, dotted, pruinose [with a bloom], fibrillose, or smooth, etc.).

Interior (hollow, solid, stuffed, fistulose [tubular], etc.).

Base (shape, markings, etc.).

Mycelium (thread-like, cottony, compact, root-like, sclerotioid [hard], coloured).

Veil. (Examine young specimens).

Ring (Relative position, permanent or fugacious [quickly disappearing], etc.).

Volva. (Examine young buttons, base of stem, surface of pileus).
