o Pileus: white
o No volva

Question 2

Coprinus (ink cap)

o Hymenium includes: basidium & basidiospores (pg 524)
Basidia
Cystidia
Other sterile cells
o Cystidia: long, cylindrical cells which arise in the hymenium along with the basidia or in the trama

Question 3

What does the hymenium of coprinus contain?

Answer 3

basidia
cystidia
other sterile cells

Question 4

cystidia

Answer 4

long, cylindrical cells which arise in the hymenium along with the basidia or in the trama
provide moisture

Question 5

trama tissue

Answer 5

tissue b/w basidium

non-spore producing tissue of gills

Question 6

Boletus (penny bun)

Answer 6

ecotmycorrhizal
spore production occurs in gills rather than on the surface of the gills
basidiocarps

where does spore production occur in Boletus?

Answer 7

tubes rather than on the surface of the gills

Question 8

What are the features of Basidiomycota?

Answer 8

4 basidiospores form from a basidium (site of karyogamy & meiosis)
Septae present with a pore
clamp connections

Question 9

Dolipore septum

Answer 9

specialized dividing walls b/w adjacent cells which permits cytoplasmic continuity b/w adjacent segments

Question 10

What determines the phyla of Basidiomycota?

Answer 10

8

Question 15

gymnocarpous

Answer 15

sporocarp exposed at the beginning of development

Question 16

Hemianicarpous

Answer 16

enclosed at first & becomes exposed as the basidiospores are fully developed

Question 17

Angiocarpous

Answer 17

sporocarp enclosed until basidiospores are fully developed

peridium is opened & decayed

Question 18

What is significant about the septae in Agaricomycete?

Answer 18

aren’t separated by septae

Question 19

What are the 2 kinds of basidia in Agaricomycete?

Answer 19

Probasidium: site of karyogamy
Metabasidium: site of meiosis

Occurs in the same space since there is no separation by septae `

Russula 
Hydnum 
Polyporus

Question 21

Sphaerocysts

Answer 21

globular cells found in the trama, provide brittle texture

Question 22

Answer 23

hydnum

Question 24

How are sphaerocysts & cystidia different?

Answer 24

sphaerocysts are located in the trama

cystidia is located along the basidia & the trama

Question 25

Nidulariacea Geastracea Lycoperdaceae Phallalaceae

Question 27

What are the features of the 4 families in Gastromycetes?

Answer 27

o 4 spores formed on basidium, not forcibly discharged o Basidiocarp is angiocarpic & covered by a multilayer peridium o Basidia produced in or on initially fleshy tissues called gleba o Basidia disintegrate & the gleba is composed of powdery spores & basidial remains

Question 28

What is the bird's nest fungi?

Answer 28

Cyanthus (Nidulartiaceae in the Agaricales)

Question 29

What is the earth star fungi? & what is unique about its peridium?

Answer 29

Answer 30

Lycoperdon (Lycoerdaceae of the Agaricales) pore on outside of peridium, spores on outside peridium is a single layer

Question 31

Describe the spore exposing function of mutinus

Answer 31

o At first, egg shaped with a peridium covering a gelatinous layer o During maturation, internal stipe like structure pushes the gelatinous layer with spore through the peridium exposing the spore mass o Peridium remains as the volva o Insect attracting
