Abstract:

Eight species of tropical timber woods Chrysophyllum cainito, Ocotea rodiaei, Pinus caribaea, Pouteria chiricana, Prioria copaifera, Rhizophora mangle, Symphonia globulifers, and Tabebuia pentaphylla were submerged in estuaries near the entrances of the Panama Canal. These species were chosen according to their susceptibility to attack by marine borers and were invaded by salt-tolerant fungi, mostly imperfect species. Fungus infestation varied from almost none to very heavy in less than six weeks, but the amount of mycelium in the woods bore no apparent relation to either animal attack or salinity. Ocotea rodiaei greenheart and Rhizophora mangle red mangrove were practically fungus-free at the end of the test. Prioria copaifera cativo was filled with mycelium, and the others were invaded by scattered hyphae. Author
