Which one is correctly matched ?
(a) Agaricus - Smut
(b) Ustilago - Mushroom
(c) Puccinia - Insectivorous plant
(d) Deuteromycetes - Imperfect fungi

Options

A. Agaricus - Smut
B. Ustilago - Mushroom
C. Puccinia - Insectivorous plant
D. Deuteromycetes - Imperfect fungi

Answer

To determine which option is correctly matched, we will analyze each of the given pairs one by one.

### Step 1: Analyze Option (a) Agaricus - Smut
- **Agaricus** is a genus of fungi that includes many types of mushrooms, such as the common button mushroom.
- **Smut** refers to a group of fungi that primarily affect plants and are characterized by their dark, powdery spores.
- **Conclusion**: This option is incorrectly matched because Agaricus is not a smut; it is a type of mushroom.

### Step 2: Analyze Option (b) Ustilago - Mushroom
- **Ustilago** is a genus of fungi known as smut fungi, which are parasites of plants.
- **Mushroom** refers to the fruiting body of certain fungi, particularly those in the Agaricus genus.
- **Conclusion**: This option is incorrectly matched because Ustilago is not a mushroom; it is a smut fungus.

### Step 3: Analyze Option (c) Puccinia - Insectivorous plant
- **Puccinia** is a genus of fungi known as rust fungi, which primarily affect plants and are not insectivorous.
- **Insectivorous plants** are plants that derive some or most of their nutrients from trapping and consuming insects.
- **Conclusion**: This option is incorrectly matched because Puccinia is not an insectivorous plant; it is a rust fungus.

### Step 4: Analyze Option (d) Deuteromycetes - Imperfect fungi
- **Deuteromycetes** is a group of fungi that are known as "imperfect fungi" because they do not have a known sexual reproductive stage.
- **Imperfect fungi** refers to fungi that do not fit into the traditional classification of fungi based on sexual reproduction.
- **Conclusion**: This option is correctly matched because Deuteromycetes are indeed referred to as imperfect fungi.

### Final Answer:
The correctly matched option is **(d) Deuteromycetes - Imperfect fungi**.
