Sterile elements: cystidia, hyhidia & paraphyses

meiospore producing basidia

Question 22

cystidia

Answer 22

contain water & contribute to a moist atmosphere where the fruiting body occurs

Question 23

sub-hymenium

Answer 23

pseudo tissue layer apart of the non-fertile trama tissue

2

32-64

Question 26

how are spores released?

Answer 26

catapulted out of the basidiocarp, spores are non-motile themselves

Answer 28

have concave & convex sides (egg shape)

not circular
