White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [2] diverse host range and ability to infect plants at any stage of growth makes white mold a serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.

The genus Goodyera are terrestrial plants with a fleshy rhizome with basal evergreen leaves in a rosette pattern - frequently having white or pale green markings.

The reliance of orchids on specific fungi has been widely studied, and the populations of certain fungi which are present in the soil have proved to be of greater importance in seed germination than the orchid's proximity to older plants or their geographical location, as previously assumed. [11]
Bletilla striata is a terrestrial orchid with pleated, spear-shaped leaves. It breaks dormancy in early spring, with each tuber of the previous year potentially sending out multiple shoots. These growths mature over the course of a couple months and eventually bear 3-7 magenta-pink flowers. [7]
