Approved Lists reference: SKERMAN (V.B.D.), McGOWAN (V.) and SNEATH (P.H.A.) (editors): Approved Lists of Bacterial Names. Int. J. Syst. Bacteriol., 1980, 30, 225-420 (Approved Lists of Bacterial Names in IJSEM Online - Approved Lists of Bacterial Names Amended edition).
Original publication: 1 THAXTER (R.): On the Myxobacteriaceae, a new order of Schizomycetes. Botanical Gazette, 1892, 17, 389-406. 2 McCURDY (H.D.): Studies on the taxonomy of the Myxobacterales. IV. Melittangium. International Journal of Systematic Bacteriology, 1971, 21, 50-54.

Notes:
1 In 1971, McCurdy cited Acc Nos 4500 and 5170, Thaxter Collection, Farlow Herbarium as the type material of Melittangium lichenicola [1]. However, in 1980, the Approved Lists of Bacterial Names [2] cited the strain ATCC 25944(also known as M155 = DSM 2275) as the type strain. The ATCC Website [3] also cites ATCC 25944as the type of this taxon.
2 According to the DSMZ Website [4], the strain M155 = ATCC 25944= DSM 2275 is most probably a strain of "Corallococcus sp.".
3 According to the DSMZ [4] and to Spröer et al.[5], the strain M201 = ATCC 25946= DSM 14877 = NBRC 100091 is the neotype of Melittangium lichenicola. However, any neotype strain has been proposed in the IJSB/IJSEM (see, Rule 18c)!
4 According to Lang and Spröer 2009 [6], the strain ATCC 25944and its derivative DSM 2275 are not members of the genus Melittangium but of the MyxococcusCorallococcus clade. Since the morphology of strain ATCC 25496is characteristic for Melittangium lichenicola and the rRNA gene sequences represented by GenBank accession numbers AM930269 and AM930267 cluster with other sequences derived from Melittangium strains, it is inferred that these sequences are the correct ones for ATCC 25946and that strain ATCC 25946(= DSM 14877) is a representative of the species Melittangium lichenicola. For these reasons, Lang and Spröer 2009 [6] request an Opinion to the effect that ATCC 25944be rejected as the type strain of Melittangium lichenicola and be replaced by strain ATCC 25946(= DSM 14877), which was suggested as a reference strain for this species by McCurdy 1971[1]. Opinion pending.
