You dig up a large mass of fungal filaments. Upon close examination, you find cross-walls composed on chitin. Which of the following describes what you dug up?
A) a mycelium with septate sporangium
B) a sporangium with nonseptate sporangium
C) a mycelium with septate hyphae
D) hyphae with nonseptate mycelium
E) an ascocarp with nonseptate hyphae
Septate Hyphae
Hyphae with cross-walls or septa that divide the filamentous structures into separate cell-like compartments, common in many fungi.
Mycelium
Tangled mass of hyphal filaments composing the vegetative body of a fungus.
Chitin
A long-chain polymer of N-acetylglucosamine, a derivative of glucose, and is a primary component of cell walls in fungi and the exoskeletons of arthropods.
- Categorize fungi based on their morphological structures and understand the composition of fungal cell walls.

Final Answer :
C
Explanation :
The presence of cross-walls composed of chitin indicates that the sample is composed of septate hyphae. Therefore, the only option that fits with this description is a mycelium composed of septate hyphae (option C). The other options either involve nonseptate hyphae (options B and D) or have different structures (options A and E).
