Distinct mycelial network architectures during early development of Trichoderma atroviride and Neurospora crassa.

N. crassa develops faster, more hierarchical mycelial networks, while T. atroviride forms decentralized, isotropic structures during early growth stages.

• Why it matters: Understanding early fungal network formation is crucial for insights into their foraging, resource transport, and resilience, yet little is known about these initial developmental processes.
• What they did: The study used label-free microscopy and automated image analysis on 2D colonies, applying graph theory metrics to compare early hyphal network evolution in two model fungi.
• The result: Findings reveal distinct architectures: N. crassa's hierarchical, anisotropic networks enable rapid expansion, whereas T. atroviride's decentralized networks offer robustness, informing how fungi adapt to their environments.
