Table S3. Moths (Lepidoptera) collected and sampled for viable fungi at two sites. Top BLAST matches are provided to indicate the taxonomic affinity of sterile cultures, rather than to identify these cultures to species.

(a) Letters after names indicate infection status of plant: U – uninfected, C - infected with C. paspali, F - infected with C. paspali that in turn is infected with Fusarium.

(b) Locations correspond to Stowe Farm (SF-FL) in Gainesville, FL, collected on 18 August 2004 and to Couch Farm (CF-NC) in Durham, NC, collected on 19 September 2004.

(c) Letters/symbols indicate taxonomic affiliation of BLAST matches: F – Fusarium match; P –Pleosporales match; * - matches Fusarium or members of the Pleosporales, but did not group with endophytes or isolates from Paspalum florets.

(d) All sequence comparisons between samples and the top BLAST matches resulted in E-values of 0.0 except for the following sample numbers: 7426 (E-value = 1e-81), 7420 (E-value = 4e-151), 7422 (E-value = 7e-151), 7415 (E-value = 4e-127), 7667 (E-value = 3e-126), and 7683 (E-value = 3e-98).

(e) Samples were grouped on the basis of 100% ITS sequence similarity. Numerical proximity does not indicate sequence similarity. # - groups that include endophytes and samples from moth bodies; ° - groups that include samples from florets and from moth bodies; #° - groups that include endophytes, samples from florets, and samples from moth bodies.
