One to five weeks after the grass seeds germinate, the mycelium , or vegetative filaments of the fungus, migrate to the lower part of the stem.
The primary function of the fungal mycelium is absorption of nutrients from the soil, and the translocation of these materials to the host.
Once excreted, the fungal mycelium [the mass of hyphae emanating from the fungus] grows into tiny spheres, about the size of a small pinhead.
Toxins occur in both the mycelium and spores of fungi.
The release of spores and mycelial fragments can be a source of inhalational and dermal exposures.
This is useful for detecting candidal hyphae, mycelial tangles and spores.
Some fungi may produce both yeast and mycelial mold phases.
At this time, the diameter of the macerated area was approximately 6 cm, and mycelial growth and esporulation were evident.
A tuft of whitish pink mycelial growth may be seen on the seed.
Fungal mycelia are capable of rapid and comprehensive exploration and colonization of nutrient patches.
