Which is not correct for fungi belonging to the class deuteromycetes ?

Options

A. Commonly called imperfect fungi
B. Reproduce only by asexual spores
C. Includes only parasitic fungi
D. Mycelium is septate and branched

Answer

To determine which statement is not correct for fungi belonging to the class Deuteromycetes, we can analyze the characteristics of this class step by step:

### Step 1: Understand the Definition of Deuteromycetes
Deuteromycetes, also known as imperfect fungi, are a class of fungi where the sexual reproductive stage has not been observed. This lack of a known sexual form is a key characteristic that defines this group.

**Hint:** Remember that Deuteromycetes are called "imperfect fungi" because their sexual reproduction is not observed.

### Step 2: Reproduction in Deuteromycetes
These fungi primarily reproduce asexually through structures called conidia. Asexual reproduction is the main mode of reproduction for Deuteromycetes.

**Hint:** Focus on the fact that Deuteromycetes reproduce only asexually, which is a defining feature.

### Step 3: Types of Fungi in Deuteromycetes
Deuteromycetes can be saprophytic (feeding on dead organic matter), parasitic (feeding on living hosts), or decomposers (breaking down organic material). Therefore, they are not limited to just parasitic fungi.

**Hint:** Consider the ecological roles of Deuteromycetes, which include saprophytes and decomposers, not just parasites.

### Step 4: Structure of Mycelium
The mycelium of Deuteromycetes is typically septate (having divisions or septa) and branched. This structure is common in many fungi.

**Hint:** Mycelium characteristics can help identify fungi; remember that Deuteromycetes have branched and septate mycelium.

### Conclusion
Based on the analysis:
- The statement that "Deuteromycetes include only parasitic fungi" is **not correct** because they can also be saprophytic and decomposers.

**Final Answer:** The statement that is not correct for fungi belonging to the class Deuteromycetes is that they include only parasitic fungi.
