In a culture of hyphae of unknown origin, you notice that the hyphae lack septa and that the fungi reproduce asexually by using clumps of erect stalks. However, at times sexual reproduction can be observed. To what group of fungi would you assign it?a. Chytridiomycotab. Basidiomycotac. Ascomycotad. Zygomycota
How can ascomycetes be distinguished from basidiomycetes?a. Ascomycete hyphae have simple pores in their septa and lack clampconnections, whereas basidiomycete hyphae display complex septalpores and clamp connections.b. Ascomycetes produce sexual spores in sacs, whereasbasidiomycetes produce sexual spores on the surfaces of clubshaped structures.c. Ascomycetes are commonly found in lichens, whereasbasidiomycetes are less commonly partners in lichen associations.d. Ascomycetes are not commonly mycorrhizal partners, butbasidiomycetes are commonly present in mycorrhizal associations.e. All of the above are correct.
You are given a fungus to identify. It has a fruiting body that contains many structures with eight haploid spores lined up in a row. What kind of fungus is this?
A.
zygomycete
B.
chytrid
C.
deutromycete
D.
ascomycete
E.
glomeromycete
It is not D
