indeterminate growth form in zoosporic fungi. Effectively, a mycelium except usually much finer filaments that are closer in size to rhizoids.

a enucleate rhizoidial system extensive enough to resemble the indeterminate mycelium produced by Ascomycetes, Basidiomycetes, and Zygomycetes; one of several thallus arrangements in the order Chytridiales.

Branching, anucleate or sparsely nucleate, rhizoidal filaments of variable width forming part of the thallus in some fungi. (Pl. rhizomycelia.) ( 16)
