1 What is the growth form of this chytrid fungus?

2 What is the growth form of this chytrid fungus?

3 In chytrid fungi, what term best describes the possession
of multiple zoosporangia?

4 In chytrid fungi, what term best describes the possession
of one zoosporangium?

5 What type of life cycle is illustrated here for Allomyces?

6 Name the structure above that produces spores in the ASEXUAL
life cycle of Allomyces. What is the ploidy level of the zoospores produced within this structure?

7 What is the name of this structure in Allomyces? What type of cells
(including ploidy level) are produced inside these structures?

8 What is the name of the orange structures in Allomyces
depicted above? What cell type (including ploidy level) is produced inside these structures?

9 What is the name of the clear structures in Allomyces
depicted above? What cell type (including ploidy level) is produced inside these structures?

10 Does the above illustration illustrate the anamorph or the teleomorph of Rhizopus?

11 In Rhizopus, what is the name of the sporangium stalk shown above?

12 In Rhizopus, what is the ploidy level of the hyphae
depicted above?

13 How do you know that the hyphae above do NOT belong to
ascomycete or basidiomycete fungi?

14 Does the above illustration illustrate the anamorph or the teleomorph of Rhizopus?

15 In the Rhizopus teleomorph, what term best describes
the hyphal tips above?

16 In the Rhizopus teleomorph, what term best describes
the hyphal tips above?

17 In the Rhizopus teleomorph, what term best describes
the dark structures above?

18 Name the structure above which erupts from the
zygosporangium to release haploid spores

19 Where does one find the only diploid cells in the life cycle of
Rhizopus shown above?

20 What happens to the diploid nuclei inside the dark structures above?
What type of cells do these produce? What is the ploidy level of These cells?

21 How do you know that the above ascomycete hypha do not belong
to a zygomycete fungus?

22 Are the above structures represent features of the anamorph or
Teleomorph in Aspergillus?

23 What type of spores are produced in the anamorph stage of ascomycetes?
What is the ploidy level of these spores?

24 What is the name of the stalk bearing the spores above?

25 Name the structure (with trichogyne) above that receives nuclei from
the antheridia.

26 Name the dikaryotic filaments above

27 What term is often used for the hook-like tip of an
ascogenous hypha?

28 What will happen to the two nuclei at the tip of this
ascogenous hypha?

29 What will happen to the diploid nucleus at the tip of this ascogenous
hypha?

30 Give the general term for the spores shown above,
and state the ploidy level of each.

31 What is the general term for the sac above, which contains
Name the sac whow above, which contains the spores produced by a typical ascomycete What is the general term for the sac above, which contains eight spores

32 Name the ascus type above, in which the ascus wall liquifies and
disintegrates to release the ascospores

33 Name the ascus type above, in which the inner layer slides up from
inside the outer layer

34 Name the ascus type above, in which the tip opens via a ring,
lid or pore

35 Give the general term for the ascomycete structures above,
which produce asci filled with ascospores

36 What is the general term for the fertile surface of an ascoma?

37 What type of ascoma is shown above?

38 What type of ascoma is shown above?

39 What is the general term for the
sterile tissue that elevates all those perithecia. Claviceps

40 What type of ascoma is shown above?

41 Name the black, dormant structure in the picture above.

42 How do you know that the hyphae above do not belong to
zygomycetes?

43 How do you know that the hyphae above do not belong
to ascomycetes?

44 What special feature in basidiomycete septa regulates flow of
materials between adjacent cells?

45 What must these two uninucleate hyphae do to initiate sexual
reproduction in basidiomycetes?

46 What is the term for the cells containing two nuclei in
basidiomycetes?

47 What will eventually happen to the two haploid nuclei at the tip of a
young basidium above?

48 What will happen to the diploid nucleus in the basidium above?

49 What will happen to the four haploid nuclei at the base of the basidium above?

50 Name the spore type above. State the ploidy level of each spore.

51 Name the stalk of each spore type above

52 Name the cell type which gives rise to the four spores above.

53 Note that the cell above is unsegmented. What term do we use
for an unsegmented basidium?

54 Note that the cell above is segmented. What term do we use
for a segmented basidium?

55 What general term is used for the structures above in which
basidiospores are mass-produced?

56 How does the hyphal composition of basidiomata differ
fundamentally from hyphal composition in ascomata? (Hint: think ploidy levels)

57 What term is used for the fertile later in a basidioma?

58 Name the basidioma type above

59 What is the term for the cap in the structure above?

60 What is the term for the stalk in the structure above?

61 Name the structure at the base of the basidioma above

62 Name the indicated structure

63 Name the indicated structures

64 What type of basidioma development is shown above?

65 What type of basidioma development is shown above?

66 What type of basidioma development produced the
basidiomata above, in which there are no universal or partial veils?

67 What term is used for the sterile crossbars that keep adjacent gills
apart in many basidiomata?
