Koh, Y.-J./ Kim, G.-H./ Jeong, I.-H./ Lim, M.-T./ Park, H.-S./ Lee, G.-S./ Jo, K.-Y./ Hur, J.-S. 2007: Lichen diseases on Prunus mume caused by colonization of consortium of several crustose lichens including Parmotrema autrosinense. - Research in Plant Disease 13(3): 223-227. [RLL List # 249 / Rec.# 39333]
Abstract: Lichen is a symbiotic association which lichen-forming fungi associate with green algae or cyanobacteria capable of producing food by photosynthesis. Lichen is one of the most widely distributed eukaryotic organisms on every kind of surface of soils, rocks and trees. Lichen-forming fungi commonly colonize on the surface of barks of dead or dying trees, which they use merely as a means of support without parasitizing. Lichen consortium of Parmotrema autrosinense and several crustose lichens heavily colonized on the surface of P. mume in Suncheon, Jeonnam province in Korea. The lichen consortium on the surface of P. mume gave the affected trees a dull gray appearance and suppressed their normal growths. Severely affected twigs or branches resulted in the death when the lichen thalli were not rubbed off the barks of P. mume. Twigs or branches of P. mume were recovered from blight syndrome when the lichen thalli were rubbed off, The recovered twigs or branches became healthy and clean when 20 or thiophanate-methyl paste were treated on the barks of P. mume. This is the first report of lichen diseases on P. mume caused by colonization of consortium of several crustose lichens including P. autrosinense.
