Choose incorrect option w.r.t fungi producing endogenous asexual and sexual respectively.

Options

A. Mucor, Truffles
B. Rhizopus, Morels
C. Smut fungi, Puffballs
D. Rhizopus,Truffles

Answer

To solve the question regarding the incorrect option related to fungi producing endogenous asexual and sexual spores, we can follow these steps:

### Step 1: Understand the Terms
- **Endogenous Spores**: Spores that are produced within a structure (e.g., inside a sac).
- **Exogenous Spores**: Spores that are produced outside of a structure.

### Step 2: Analyze Each Option
1. **Mucor and Truffles**:
- **Mucor**: Belongs to Phycomycetes and produces endogenous asexual spores. **(Correct)**
- **Truffles**: Belongs to Ascomycetes and produces endogenous sexual spores called ascospores. **(Correct)**

2. **Rhizopus and Morals**:
- **Rhizopus**: Also belongs to Phycomycetes and produces endogenous asexual spores. **(Correct)**
- **Morals**: Belongs to Ascomycetes and produces endogenous sexual spores called ascospores. **(Correct)**

3. **Smut Fungi and Puffballs**:
- **Smut Fungi**: Belongs to Basidiomycetes and produces sexual spores (basidiospores) exogenously. **(Incorrect)**
- **Puffballs**: Also belong to Basidiomycetes and produce basidiospores exogenously. **(Incorrect)**

### Step 3: Identify the Incorrect Option
- The third option (Smut Fungi and Puffballs) is incorrect because both produce spores exogenously, not endogenously.

### Conclusion
The incorrect option with respect to fungi producing endogenous asexual and sexual spores is **Smut Fungi and Puffballs**.
