Name

First Last

Using a magnifying glass, you investigate some tiny, red, cup-shaped fungi on a dead log, and find that each one is lined with dark “hairs”. They belong to the genus Scutellinia and are known as

Scarlet Cups
Jelly Cups

Approximately 100
2
Over 20000
4

What is a slime mold?

A lichen
Single celled organism that fuse together to form a fruiting body.
A type of fungi

Urnula craterium would be a perfect Halloween fungus, but alas! This dark and creepy cauldron only grows in early spring. Its common name is:

Hairy Fairy Cup
Earth Tongue
Dead Man’s Fingers

Sarcoscypha occidentalis
Sarcoscypha austriaca
Sarcoscypha coccinea
Sarcoscypha dudleyi

These mushrooms are not social distancing. How would you describe them?

Single
Scattered
Caespitose
Nongregarious

You’ve discovered what looks like a morel, with a long, granular stem and a cap which turns under before it attaches to the stem. When sliced lengthwise, the mushroom is hollow from top to bottom with a definite attachment to the stem— it’s Morchella punctipes, commonly called

Tulip Morel
Mulch Morel
Half Free Morel
Fuzzy Foot

Grifola frondosa is a polypore mushroom typically found at the base of oak trees in the fall and is a choice edible. It's common name is:

In the moss on the ground you notice a slim, soft black mushroom with a stem and an elongated oval head with a groove down the middle—a member of the genus Geoglossum, what most of us call:

Ribbed Cup
Earth Tongue
Black Foot Morel
Hare’s Ear

Intermediate question. Which of these two mushrooms can turn black when bruised or cut?

Lactifluus helvus and Lactarius lignyotus
Xanthoconium purpureum and Gyroporus castaneus
Marasmius nigrodiscus and Russula compacta
Tylopilus alboater and Strobilomyces strobilaceus

Sarcoscypha austriaca, one of the first colorful cup fungi to peek out from under the dead leaves in spring, is commonly known as:

Elfin Saddle
Scarlet Cup
False Morel
Eyelash Cup

If a fungus is mycorrhizal what does that mean?

A fungus which grows in association with the roots of a plant in a symbiotic relationship
A fungus that rots wood
A fungus that releases spores to the air
A fungus that lives underground

What color are the spores of oyster mushrooms?

Green
Purple
Rusty brown
White to yellow to lyliac

Advanced question. In most guide books only one or two eyelash cup species are listed. So far we have identified 6 diffenret species using their microscopic features. Using the images of the spores and other identifying features and measurement values can you identify this species? Average 18 µm by 11 µm Q=1.65 with large warts that mostly have interconnections. Black/Brown margin hairs are ~1650 µm long, rooting with 2 to 3 forks and a pointed top. Hair width ~42µm close to base, hair wall thickness ~7µm.

Use this key to identify the exact species of we have found.

Scutellinia scutellate
Scutellinia pennsylvanica
Scutellinia crinita
Scutellinia setosa

Which one of these is this a Chanterelle mushroom?

Which of the following is false regarding the aborted entoloma?

Irregular white blobs with a marbled pinkish brown interior
It is edible
Caused by Entoloma abortivum parasitizing Armillaria species
Turns bright blue when cut

On a damp log, you find a decorative grouping of soft gray, merging circles and ovals, each surrounded by clean white as they spread along the surface of the log. Its official name (quite a tongue twister) is Kretzschmaria deusta. The soft colors will soon become black and flaky, which has earned it the name:

Black Flakes
Black Crust
Spreading Crust
Brittle Cinder

Intermediate question. Which mushroom toxin causes an adverse reaction to alcohol similar to Disulfiram (Anatbuse) used to treat chronic alcoholism?

α-Amanitin
Coprine
Muscarine
Gyromitrin

Most people who love wild mushroom hunting would be excellent partners to be quarantined with for two months.

No Way
Of course they would
I'm not too sure of that
Only if they were good cooks

Are those creepy fingers sticking out of the ground? Grayish blue-green with lighter “nails” in May and June; later in the year they will turn black and a bit bumpy. They are Xylaria polymorpha, commonly known as:

Devil’s Urn
Black Crust
Dead Man’s Fingers
Brittle Cinder

Advanced question. This is a DNA sequence or barcode for an ITS region of a fungi. What species is it from?

You will need to use the online BLAST server to identify it. Tip: Search the entire nucleotide database rather than the ITS type sequence subset to obtain a good result.

Live trees
Wood mulch
Rotting logs
The ground
