Blue star

The Blue star (Amsonia orientalis) is a species in the genus Amsonia. It is currently classified as Critically Endangered on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Botryotinia calthae is an ascomycete fungus in the family Sclerotiniaceae, the sexual stage of a Botrytis-like pathogen that infects marsh marigold (Caltha palustris) in wetland habitats. It forms sclerotia in infected plant tissue that persist in soil to initiate future infections. As a necrotrophic pathogen, it kills host tissue and then feeds on the resulting dead material.
