MUSHROOMS OF NORTH AMERICA COLLECTION Slides order #230X .........$72.50

Detailed, technical and comprehensive. Presents specialized information on the
classification, structure, edibility and food value of mushrooms. Their role in nature and
conditions for growth are also discussed. Photographs and detailed descriptions of
species of boletes, pholiotas, collybias, hygrophorus, marasmius, milk mushrooms, and
teeth, jelly and cup fungi. Coverage also includes slime molds and plasmodium; the waxy
laccaria, tawny grisette, chanterelle, Mycena leiana, Verpa conica, horse mushroom,
Cortinarius armillatus, yellow-cracked bolete, Boletus badius, rustspot fungus, white
morel, Xeromphalina campanella and spore prints.(2 slide sets) 4O slides and 2 guides.

CONTENT SAMPLE: 21154 The edible bolete (Boletus edulis) is a spore fungus.
Containing a high proportion of protein and a fair amount of vitamin D, it is the most nourishing of
all edible mushrooms. In Europe, where it is also known as the Cope, pennybun, or steinpilz, the
edible bolete is a well-known and highly prized species and is even used in several brands of
packaged soups.

Unfortunately in eastern North America, it is difficult to find the edible bolete free from
insect larvae. As indicated by the condition of this specimen, red squirrels and chipmunks also
have a fondness for this mushroom

A commonly occurring mushroom, the edible bolete may be found singly or in groups in
the woods from June until October. The broadly convex cap of this species, 6.4 to 15.3 cm (2.5 to
6 in.) in diameter, varies in color from yellowish brown to red-brown. It is usually dry, but becomes
slippery or viscid in wet weather. The white or yellowish flesh, which has a sweet and nutty taste,
is firm and does not change when bruised. The tubes, which are depressed just at the stem, are
initially white, later turning greenish yellow. The whitish to yellow or brownish stem, 6.4 to 15.3
cm (2.5 to 6 in.) long and 1.3 to 3.2 cm (.5 to 1.3 in.) thick, is of uniform thickness or swollen at
the base. The stem is reticulate, marked with a network of veins, either entirely or only at the top.

A spore deposit is obtained from boletes in the same way as from gill fungi. The edible
bolete gives an olive- to ochre-brown spore print.

REVIEWS:"...excellent photographs...extensive study materials.... The mushrooms and
fungi are photographed in their natural settings and offer a clear example of each species."

MUSHROOMS AND FUNGI Slides order #225 ............$42.50

Photographs of common, rare, edible and poisonous mushrooms, in natural
settings. Text discusses iden-tification, superstition and interesting facts. Includes honey
fungus, Jack-o-lantern, coral, violet cortinarius, mycena, hygrophorous, true and false
deathcap, fly amanita, ink cap, pine cone, clavaria, puffball and polypores. 2O slides and
guide.

CONTENT SAMPLE: 3587 This looks like it is also a Mycena, doesn’t it? This
mushroom is of the Hygrophorus genus, which is easily recognized by the waxy, wide-spaced
gills. None of this genus are poisonous and some are considered excellent eating. All grow close
to the ground, often in grass. The term "hygrophorus" is from two Greek words meaning "bearing
moisture" and refers to the waxy, moist look of the cap. As you can see, some of these
mushrooms are extremely attractive and brightly colored.

MYXOMYCETES: THE TRUE SLIME MOLDS Slides order #235 ...........$42.50

Long a puzzle to taxonomists because they possess both plant-like and
animal-like characteristics, slime molds have now been grouped in a separate kingdom.
Details the characteristics and behaviors of these strange organisms so interesting to
cancer researchers today. Striking close-up photographs and detailed information are
presented on 19 different species. 2O slides and guide.

CONTENT SAMPLE: Introduction. Biologists have traditionally divided living organisms
into two major groups, the Plant and Animal Kingdoms. While it is easy to assign an oak tree or a
blue whale to the appropriate kingdom, certain organisms are not as easily placed. The fungi,
protozoans and some algae do not seem to fit either kingdom very well, often combining both
plant and animal characteristics in a single organism. The Myxomycetes or true slime molds are
perhaps one of the best examples of organisms with this dual nature. Myxomycetes have been
studied for nearly 300 years, but early observations were made only on the plant-like or fungal-like
fruiting stage. Although their study to date has been mostly by mycologists (people who study
fungi), workers in many fields from genetics to cancer research have begun to use slime molds in
modern research.

The plant-like/fungal-like phase of the slime mold life cycle is the most conspicuous in
nature and consists of spore bearing structures of various types. The fruiting bodies contain a
variable number of spores, just a few in smaller forms, but many thousands of spores in larger
types. These spores are released into the environment in a variety of ways, and are usually
spread through the actions of wind, water or insects. When spores fall in conditions of proper
temperature and moisture, the spore wall opens and releases either an animal-like flagellate
swimming cell, the swarm cell, or an amoeboid cell, the myxamoeba. These two cell types are
interconvertible, swarm cells predominating in very wet conditions, myxamoeba in drier conditions.
These cells can ingest a wide variety of bacteria, yeasts, and fungal spores, and are capable of
dividing numerous times to produce large populations of cells. Eventually they act as gametes or
sex cells, fusing in pairs to give rise to the next vegetative phase, the plasmodium....

REVIEWS: "...displayed in an array of colors and forms that should pique the...most
jaded and finicky observers. The text is well written and adaptable.... The slides are of excellent
quality...recommended for any course in which the living world is surveyed." Journal of College
Science Teaching. "Recommended." Booklist.
