Recursion level This is the number of steps to use to grow the fungus;
See example here
Example value: 18 (18-45 recommended)
Probability of generating a primary conidiophore
Branch with probability:Go straight with probability:
 How long to grow the hyphae before a primary conidiophore is developed. Soon to be implemented as a Gamma distribution.
Example values: Branch: 0.3, Go straight: 0.7
Hyphae cell length
"#" options:
cell lenght of 10 cell lenght of 3 How long should the hyphae cells be, and with what probability should each occur.
Example: cell with length 3 and with length 10. You can change the number of options for a bigger variety.
Example values: Length 3: 0.5, Length 10: 0.5
Probability of generating first spore on primary conidiophore
Grow conidiophore with probability:Spore with probability:
 First spore on primary conidiophoreWhen the hyphae generates a primary conidiophore, how long to grow it before the first spore occurs. Soon to be implemented as a Gamma distribution.
Example values: Grow: 0.3, Spore: 0.7
Probability of a sub-conidium conidiophore elongation
Spore and develop this elongation:Just spore and do not develop:
sub-conidium development
Develop a sub-conidium elongation
no sub-conidium development
Do not develop, just spore
Example values: Develop: 0.3, Just Spore: 0.7
Probability of "after-sub-conidium" development
Continue to elongate:Skip a turn (wait):
Spore: 
 
Elongate after a sub-conidium development
Continue to elongate
Skip a turn after a sub-conidium development
Skip a turn (wait)
Spore after a sub-conidium development
Spore
Example values: Elongate: 0.1, Skip Turn: 0.1, Spore: 0.8
Probability of "after-spore" conidiophore developments
Just spore again:Skip a turn (wait):
Lateral intra-conidium conidiophore development:Apical conidium terminus conidiophore development:
Create another spore
Create another spore
Skip a turn after the spore
Skip a turn (wait)
Create a later-intra development
Lateral-intra development
Create an apical conidium terminus
Apical conidium terminus
Example values: Spore: 0.6, Wait: 0.0, Lateral: 0.1, Apical: 0.3
Probability of "after-apical" developments
Continue to elongate:Skip a turn (wait):
Spore: 
 
Elongate after an apical development
Continue to elongate
Skip a turn after an apical development
Skip a turn (wait)
Spore after an apical development
Spore
Example values: Elongate: 0.1, Skip Turn: 0.1, Spore: 0.8
Probability of "after-lateral intra" developments
Continue to elongate:Skip a turn (wait):
Spore: 
 
Elongate after a lateral-intra development
Continue to elongate
Skip a turn after a lateral-intra development
Skip a turn (wait)
Spore after a lateral-intra development
Spore
Example values: Elongate: 0.1, Skip Turn: 0.1, Spore: 0.8
Rotate about x
"#" of options:
RuleProbability (0 - 1.0)
Rotation about x in degrees, example::
Rule: +(10) Probability: 0.3
Rotate about y
"#" of options:
RuleProbability (0 - 1.0)
Rotate about y in degrees, example::
Rule: &(10) Probability: 0.3

Random Seed Change this to any 6-digit number to get a different fungus from the same type;
272344 and 272349 are ok;
Basic Angle 1-360; in case angle not explicitly specified
Axiom The basic rule
