Complex host-pathogen coevolution in the Apterostigma fungus-growing ant-microbe symbiosis

Table 1 Distribution and diversity of Apterostigma Escovopsis infections.

Cultivar Clade	# colonies successfully sampled for symbiotic microbes	# colonies infected with Escovopsis	# colonies infected with...				# colonies infected with multiple Escovopsis types
			brown Escovopsis	yellow Escovopsis	white Escovopsis	pink Escovopsis
G2	350	185 (52%)	141	64²	17	0	35¹
G3	55	6 (11%)	0	1²	0	5	0
G4	6	4 (67%)	4	0	0	0	0

Escovopsis types are identified here according to spore-color. ¹ For the G2-cultivar colonies, the number of infections based on spore-color exceeds the number of total infections because many colonies were infected with two or three Escovopsis types. ² Though sharing a similar spore-color, the G2-attacking and G3-attacking yellow Escovopsis have distinct micromorphologies (Currie, unpublished).
