Conteúdo: 	A survey of fungi ocurring in pine seeds, diseased pine seedlings, and pine bark mulch at southern pine nurseries identified 41 taxa in 23 genera. Pathogenicties of 35 representative isolates from 12 species or taxa of fungi were tested on slash pine seedlings. Isolates of Fusarium moniliforme var. moniliforme, F. oxysporum, F. fusarioides, F. solani, Alternaria alternata, Rhizoctonia solano AG-4, binucleate Rhizoctonia-like fungus CAG-3, Pyhium aphanidermatum, Penicilium expansum, andCladosporium cladosporioides caused preemergence damping-off. Isolates of R.solani, a binucleate Rhizoctonia-like fungus, and P.aphanidermatum also caused significant amounts of postemergence damping-off. F. moniliforme var. subglutinans, F. m. var. moniliforme, and F. m. var. intermedium initiated infections from seedborne inoculum to the cotyledons. F. m. var. subglutinans was the most virulent of these three varieties of  F. moniliforme. In growth chambers at 20 and 30 C. F. m. var. moniliforme, and F. m. var. intermedium needed higher temperatures tocause infections. This is the first report of F. m. var. intermedium causing a plant disease.
