It was successively observed how the Conchocelis germlings grew in the shells which were faced sidewards in culture vessel.
The germlings spread the filaments inwards far off from the shell surface. Accordingly they tend to run horizontally at a right angle to gravity.
When the shells were laid in a prone position, the filaments also grew into inner layer of shells receding from their surfaces. Namely, they run upwards against the gravity.
Anastomosed filaments always throve in the close layers which run parallel to the shell surfaces having no connection with the direction to which their surfaces were faced.
Generally speaking, gravity shows no influence on branching and growth in Conchocelis filaments.
