Aerial mycelia and methods of making same

A method of making an aerial mycelium, comprising:

• incubating a growth matrix in a growth environment for an incubation time period, wherein the growth matrix comprises a substrate and a fungus;
• introducing aqueous mist into the growth environment throughout the incubation time period or a portion thereof;
• and
• producing extra-particle aerial mycelial growth from the growth matrix;
• wherein introducing comprises introducing the aqueous mist into the growth environment resulting in a mean mist deposition rate of at most about 0.45 microliter/cm2/hour.
