Table 1.

EA-positive species and average alkaloid composition.

Species are listed by ITS phylogenetic order with lines separating species from different origins of symbiosis (see Fig. 3). Values are raw ergot alkaloid concentrations (μg/g). The last six species were not included in our phylogeny.

Bolded values note the ergot alkaloid with the highest concentration in the species.

^aLysergic acid α-hydroxyethylamide.

^bPreviously unidentified species reported with ergot alkaloids.
