Question 0

What are the gills of the mushroom called?

Answer 0

The lamellae.

Question 1

What is the cap of the mushroom called?

Answer 1

The pileus.

Question 2

What is the stem of the mushroom called?

Answer 2

The stipe.

Question 3

What is the ring around the stipe of the mushroom called?

Answer 3

The annulus.

Question 4

What is the cup on the end of the stipe of a mushroom called?

Answer 4

The volva.

Question 5

What role is played by a Woronin body?

Answer 5

To seal the septal pore in response to wounding.

Question 6

Do puffballs have ballistospores?

Answer 6

No.

Question 7

Why is it that ballistospores launch commonly around 0.1 mm?

Answer 7

If they were to go too far they would hit the surface of the adjacent gill and accomplish nothing.

Question 8

What is the hymenium?

Answer 8

The tissue layer containing the spore bearing cells.

Question 9

Where is the hymenium located in a gilled mushroom?

Answer 9

It is the layer of cells on the surface of the gills.

Question 10

Where is the hymenium located in a bolete?

Answer 10

It is the spongy mass of downward-pointing tubes

Question 11

Where is the hymenium located on a shelf fungus?

Answer 11

On the sides of polypore tubes.

Question 12

Where is the hymenium located on an ascomycete cup fungus?

Answer 12

On the concave surface of the cup.

Question 16

Order

Answer 16

-ales

Question 17

Family

Answer 17

Question 18

Genus

Answer 18

-us

Question 19

Answer 19

Genus ________

Question 20

Why are fungi called osmotrophs?

Answer 20

Because they absorb their food.

Question 21

How do fungi use growth to colonize and extract nutrition from their substrate?

Answer 21

The hyphal tips secrete enzymes that degrade substances. Repeated branching produces many growing tips which are the greatest export of substance-degrading enzymes.

Question 22

Brown rot fungi.

Answer 22

They degrade only the white cellulose and leave the brown rot lignin behind.

Question 23

White rot fungi.

Answer 23

They degrade the brown lignin and leave white cellulose.

Question 24

Phragmobasidium.

Answer 24

Septate, found in the hymenium.

Question 25

Holobasidium.

Answer 25

Aseptate and unicellular, found in the hymenium.

Question 26

Why is the basidium so important in a basidiomycete life cycle?

Answer 26

They create the basidiospores which keep the life cycle going.

Question 27

What role is played by Buller’s drop?

Answer 27

It changes the center of gravity in the basidiospore and results in forcible discharge.

Question 28

Where do we find flagella in fungi?

Answer 28

Only in chytrids, they have flagellated gametes.

Question 29

What is the function of hyphal septa?

Answer 29

To allow the movement of cytoplasm and sometimes nuclei.

Question 30

Monohyphae.

Answer 30

Generative hyphae, septate, thick or thin walled, may or may not have clamps

Question 31

Dihyphae.

Answer 31

Thick walled, non-septate, skeletal hyphae. Contains generative hyphae and one of the other two types.

Question 32

Trimitic hyphae.

Answer 32

Contains mono and di hyphae plus binding hyphae.

Question 33
