Each Specimen will now be shown and discussed

1) Phaeolus schweinitzii:
Commonly known as velvet-top fungus, dyer's polypore, or dyer's mazegill,

The dyer's polypore is an excellent natural source of green, yellow, gold, or brown dye.

This is a classic "butt rot" fungus that attacks trees through their roots and produces decay in the root system and in the heartwood of trees.

Phaeolus schweinitzii is usually found near the base of conifer trees.


2) Boletus smithii:
a colorful mushroom, with yellow pores that slightly bruised blue when scraped. The red and yellow stipe serves as a good field identification clue. The cap often turns a shade of red with age

The underside of the cap is made of tubes. These tubes open up into pores at the bottom.

This is said to be an edible species.


3) Hydnum umbilicatum:
Often called the "hedgehog mushroom,"

Hydnum repandum has pale orange-tan colors, a terrestrial habitat, and spines or "teeth" on its underside.

There are several larger species of Hydnum in North America called Hydnum repandum


4) Lyophyllum decastes

Lyophyllum decastes is known as the fried chicken mushroom.

It is an edible species of fungus in the Lyophyllaceae family. Commonly found near gravel

Lyophyllum is a genus of about 40 species of fungi


5)Thaxterogaster Pingue - false truffle
Also called: Cortinarius pingue

It does not taste like a truffle, the taste nasty

Its cap begins to develop but never opens up to expose the gills. The gills are therefore poorly formed.

Pingue means "greasy" in Latin. The term refers to the slippery-feeling peridium of this mushroom


6) Amanita Franchettii

This Amanita has not yet opened.

The edibility of this Amanita is in doubt and it has recently been implicated in the deaths of ten people in China








7) Lactarius delicious

Lactarius deliciosus, is commonly known as saffron milk-cap, red pine mushroom, or simply pine mushroom

This mushroom originated in Europe and it has been accidentally introduced to other countries under conifers. It can be found growing in pine plantations.

Michael Kuo, primary founder of the MushroomExpert website, cites Belgian mycologist Jorinde Nuytinck who determined that this mushroom is a "genetically, morphologically, and ecologically distinct European species that does not occur in North America".




8) Cantharellus Commonly called Chanterelle -

This is what people look for. Chanterelle are one of the most recognized and harvested groups of edible mushrooms.

Cantharellus is the genus of this popular edible mushrooms. They are a mycorrhizal fungi. This means that they form symbiotic associations with plants, making them very difficult to cultivate.

Caution must be used when identifying chanterelles for consumption. There are some lookalikes species, such as the Jack-O-Lantern species (Omphalotus olearius and others), which can make a person very ill.








9) Suillus lakei:
sometimes called a painted Suillus (this specimen is distorted)

Suillus lakei grows only under Douglas-fir.

The "painted Suillus" is a beautiful mushroom.
This specimen does not do it justice.

It can be recognized by its dull brick red colors, its scruffy cap, the partial veil--which is whitish to reddish and which leaves a ring on the stem-- and the fact that the flesh in the stem base turns deep green when sliced open.






10) Gomphus floccosus:

This mushroom is sometimes known as the shaggy-, scaly-, or woolly chanterelle or woolly gomphus

They are not edible. Consumption may result in nausea, vomiting and diarrhea. The onset may be delayed by up to 8–14 hours.





11) Polyporus elegans

Polyporus means "many pores"

This mushroom typically fruits on smaller hardwood sticks and decaying branches, causing a white rot.

The black base of the stalk is an important field character.


12 Amanita -- species undetermined

Note: the genus Amanita contains about 600 species of agarics including some of the most toxic known mushrooms found worldwide,

The Amanita genus also contains many edible mushrooms, but mycologists discourage mushroom hunters from selecting any of these for human consumption due to the danger of confusion between species.


13) Gastroboletus

There are many species of Gastroboletu
The edibility of most species is unknown, and those known to be edible are not highly rated.

Gastroboletus is a fungus with a cap that can vary from red to dark brown; superficially resembles a bolete

An important distinction for boletes is that Gastroboletus has tubes arranged irregularly, rather than vertically as in typical boletes.




14) Lobster
Scientific name:Hypomyces lactifluorum Lobster mushroom start out as a Russula brevipes or a Lactarius. A parasitic ascomycete grows on mushrooms, turning it a reddish orange color that resembles the outer shell of a cooked lobster.

This parasite colonizes several genera of mushrooms including Lactarius (Milk-caps) and Russula, such as Russula brevipes and Lactarius piperatus. At maturity, the parasite thoroughly covers its host, rendering its origin unidentifiable .

Lobster mushrooms are widely eaten and enjoyed. They are commercially marketed. They have a seafood-like flavor and a firm, dense texture.


15) Amanita augusta:
This mushroom was formerly known under the European name Amanita franchetii. Now it is described as a new species from California and the Pacific Northwest.

It has a gorgeous brown cap that features yellow warts.

The base of the stem features flaky yellow patches of universal veil material, and the upper stem displays a pale yellow ring.

Amanita augusta is not an edible species


16) Collybia:

Collybia grow on the decomposing remains of other mushrooms

It is a genus of mushrooms in the Tricholomataceae family




Russula olivacea:

Russula olivacea is an edible and non-poisonous Russula mushroom.

It is found mostly in deciduous and coniferous forests, mainly under spruce and beech.

The cap is convex when young but it soon becomes flat, It is yellowish-olive when young and it develops into rusty brown color.

The stem is strong, even and thick. The stem is often pale pink.

The gills are cream and they become deep ocher when old. The gills are crowded and brittle. The spores are yellow.

The flesh is firm and white. It does not have a distinctive smell and it has a mild taste.






18) Russula brevipesz:

Russula brevipes is edible, but it certainly is not choice.

This mushroom is sometimes parasitized by the parasitic ascomycete Hypomyces lactifluorum.

This parasite turns the color of the mushroom into an orange color similar to shell of a lobster.

The parasitization transforms this mushroom into the much more desirable edible mushroom known as a lobster mushroom.






19) Amanita fulva:
Sometimes called the tawny grisette

Note that the base of this mushroom is enclosed in a sacklike, white volva that fits loosely around the stem and often discolors tawny brown.

This mushroom is found frequently in deciduous and coniferous forests of Europe, and sometimes, but infrequently, in the Northwest.

Amanita fulva is one of the few edible species in the genus Amanita.

Even though this particular species of Amanita is considered edible, it must be identified with care as other members of the genus Amanita are poisonous and some are deadly.

Collection for consumption of Amanita fulva can be dangerous and is not recommended. Furthermore, some authors indicate the fungus is potentially toxic when raw, and that it is suitable for consumption only when cooked




20) Russula adusta;

This particular Russula stands out due to its mild taste. This species is common in the Pacific Northwest under Hemlock and Spruce.

Russulas are brittle-fleshed, gilled mushrooms with a central stem, without a universal veil and, without a partial veil. The spore color varies from pure white to yellow to a deep salmon or ochre.



The gills of a Russula will break when stroked with a fingertip -- and the stem will snap when bent -- " like a piece of chalk".

Lactarius, which are somewhat similar in appearance to Russula are not so brittle, and when cut or bruised, exude a milky fluid.






21) Cantharellus roseocanus:
Also known as: Chanterelle, rainbow chanterelle, .. Cantharellus cibarius.

Grows under sitka spruce, shore pine, or Engelmann spruce.

The distinguishing features of this chanterelle include (a) the bright orange false gills, which contrast markedly with the duller cap surface; and (b) the pinkish bloom that often covers young caps.

Until recently, all yellow or golden chanterelles had been classified as Cantharellus cibarius. However, DNA analysis has shown that they are a group of related species. Recently the Pacific golden chanterelle (Cantharellus formosus), Cantharellus roseocanus, Cantharellus cascadensis and others have been identified.




22) Stereum Hirsutum:
This mushroom has a life cycle somewhat similar to Lobster mushrooms discussed above. Stereum hirsutum is parasitised by certain fungus species such as the fungus Tremella aurantia. Stereum hirsutum grows on dead limbs and trunks of both hardwoods and conifers.





23) Polyporus Elegans:
Polyporus elegans is a species of fungi in the genus Polyporus. It causes a white rot of dead hardwoods.

Polyporus Elegans is saprobic and it grows on decaying hardwood sticks and small logs. It rarely grows on conifer debris.

This polypore has a fairly small size, a whitish pore surface, and a black, or half-black, central stem.

Like many polypores Polyporus Elegans is tough, and it can continue to exist for quite a while in dry weather. This results in older specimens with faded, nearly white caps and sordid brownish pore surfaces.




24) Coltricia: Coltricia is a genus of fungi that has many species. Coltricia cinnamomea is easy to dry; just set it on the table for a few days and it will harden, retaining much of its original beauty. They can be used to make little Coltricia arrangements to brighten your home.






25) Chicken of the woods:

This large, brightly colored fungus is often found in clusters but is occasionally solitary.

Older fungi are tough and they develop a sour flavor.

You can harvest the mushrooms and return the next year for another crop. Or cut just the outer edge (about 5 cm of the fungus) and return later in the season for a second helping.

Some references indicate that one should bee wary of Chickens growing on conifers (in the Northeast) as they are a different species and can cause poisoning.

However, David Arora remarks in Mushrooms Demystified that this is a foolproof and unmistakable mushroom.

I must say that this particular specimen does not look anything like other Chicken of the Woods that I have seen.
