| 3. | They reproduce only by asexual spores called as conidia. |
| 4. | They include Agaricus, Claviceps and Colletotrichum. |

The imperfect fungi which are decomposer of litter and help in mineral cycling belong to:

Hints
Deuteromycetes are commonly known as imperfect fungi because only the asexual or vegetative phases of these fungi are known. What can be the possible reason(s) of unawareness of sexual phases in these fungi?
1. Only I
2. Only II
3. Both I and II
4. Neither I nor II
| I: | Sexual phases are yet to be discovered. |
| II: | The asexual and vegetative stage have been given one name (and placed under deuteromycetes) and the sexual stage another (and placed under another class). |
1. Only I
2. Only II
3. Both I and II
4. Neither I nor II
