Note: Imhoff 2003 proposes to transfer ¤ Pelodictyon clathratiforme (Szafer 1911) Lauterborn 1913 (Approved Lists 1980), the type species of the genus Pelodictyon, to the genus ¤ Chlorobium as ¤ Chlorobium clathratiforme (Szafer 1911) Imhoff 2003, comb. nov. According to Rule 37a, bacteriologists adhering to this proposal must change the name Pelodictyon to ¤ Chlorobium.

Note: There are some controversies about the availability of the type strain DSM 5477 [1, 2]. However, according to Dr. Khursheed A. Malik (DSMZ) [3], the strain DSM 5477 is available but only to persons who are familiar with the growth of difficult phototrophic bacteria.
