Table 1. Mean colonization rate and spore density per distance.

Distance (m)	No of stations	No of pots	Colonizable pots	Colonized pots	Colonization rate (mean ± SD)	Spore density (mean ± SD; m−2)
1–5	8	48	48	40	0.83±0.20	339±123
10	4	32	31	20	0.64±0.08	214±48
30	4	52	43	6	0.16±0.19	40±46
50	4	84	75	1	0.01±0.03	3±6
80	4	136	114	3	0.03±0.02	6±4
150	4	252	193	2	0.01±0.01	2±3

600	4	1008	890	13	0.01±0.02	3±5

For each distance the number of sampling stations, the total number of pots put out, those who remained colonizable, colonized pots, mean colonization rates (ratio of colonized pots) and calculated density of spores, based on the number of colonised pots per distance from the mother colony.
