Which of the following matches is correct

Options

A. Phytopthora `rarr` Aseptate mycelium `rarr` Basidiomycetes
B. Alternania `rarr` Sexual reproduction absent `rarr` Deuteromycetes
C. Mucor `rarr` Reproduction by conjugation `rarr` Ascomycetes
D. Agaricus `rarr` Parasitic fungus `rarr` Basidiomycetes

Answer

To solve the question "Which of the following matches is correct?", we will analyze each option provided in the question step by step.

### Step 1: Analyze the first option
- **Match**: Phytophthora with Earth's update mycelium and class Vesidomycetes.
- **Analysis**: Phytophthora is known for having non-septate mycelium (aseptate), and it actually belongs to the class Oomycetes, not Vesidomycetes.
- **Conclusion**: This option is **incorrect**.

### Step 2: Analyze the second option
- **Match**: Alternaria with sexual reproduction absent and class Deuteromycetes.
- **Analysis**: Alternaria is a genus where sexual reproduction is indeed absent, and it is classified under Deuteromycetes.
- **Conclusion**: This option is **correct**.

### Step 3: Analyze the third option
- **Match**: Mucor with reproduction by conjugation and class Escomycetes.
- **Analysis**: Mucor primarily reproduces asexually and does not reproduce by conjugation. Mucor belongs to the class Zygomycetes, not Escomycetes.
- **Conclusion**: This option is **incorrect**.

### Step 4: Analyze the fourth option
- **Match**: Agaricus with parasitic fungus and class Vesidomycetes.
- **Analysis**: Agaricus is a genus of mushrooms that includes edible and poisonous species; it does not primarily act as a parasitic fungus and belongs to the class Basidiomycetes, not Vesidomycetes.
- **Conclusion**: This option is **incorrect**.

### Final Conclusion
After analyzing all options, the only correct match is the second option: Alternaria with sexual reproduction absent and class Deuteromycetes.
