Hyphae & mycelia
Treat filamentous growth as a distributed body plan optimized for exploration, absorption and local response.
Subject
Purpose
Fungi studied through hyphae, metabolism, reproduction, symbiosis, decomposition, pathogenicity and evolutionary diversity.
Structure
Entities → interactions → mechanisms → scales → measurement
Fungi reorganize familiar biological categories: their filamentous bodies, extracellular digestion and symbioses make them central to ecosystems and disease while differing sharply from plants and animals.
Treat filamentous growth as a distributed body plan optimized for exploration, absorption and local response.
Track extracellular enzymes and absorption as mechanisms for accessing complex organic resources.
Compare sexual and asexual cycles, dispersal and life histories across major fungal groups.
Study mycorrhizae, lichens and endophytes as reciprocal interactions rather than exceptions to solitary organism models.
Examine host invasion, immune interaction and secondary metabolites in plant, animal and human disease.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
fungus ≠ plant
mycelium ≠ single hypha
symbiosis ≠ mutual benefit in every case
Use these to test whether the model is becoming explanatory rather than merely familiar.
How does network growth change fungal resource allocation and competition?
Why are fungi so important to nutrient cycling despite often being visually inconspicuous?
Which traits allow transitions between mutualism, commensalism and pathogenicity?
Combine culture, microscopy, molecular identification, genomics and field ecology; morphology alone often under-resolves fungal diversity.
