The greenish-brown margin of discolored wood in three living silver maple trees, Acer saccharinum L., was examined by scanning electron microscopy and microbiological culture techniques. Micrographs of xylem vessels revealed filamentous structures; some of them appeared to be actinomycetous hyphae. Actinomycetes identified as Streptomyces parvullus Waksman & Gregory, S. sparsogenes Owen, Dietz & Camiener, and a third Streptomyces strain were isolated repeatedly from discolored wood of each tree. These isolates grew in liquid media in the presence of 0.1% (w/v) concentrations of several phenols. Although other phenols included in the test were not substantially degraded, p-hydroxybenzoic acid was utilized as a carbon source by S. parvullus. All three actinomycetes inhibited growth of selected wood-inhabiting fungi when paired on malt agar. When inoculated on sterilized sapwood and discolored wood from silver maple, the actinomycetes colonized vessel walls and occlusions, but were not observed to decay cell walls.

Antibiotic Action

Two actinomycètes (X9 and X10) isolated on a Fusarium oxysporum f.sp. albedinis strain showed antibiotic, mycolytic, and parasitism actions against nine "formae speciales" of Fusarium oxysporum. Strain X10 is included in genus Streptomyces and strain X9 in Nocardiopsis dassonvillei species (Lechevalier and Lechevalier) Meyer. The antibiotic action of Streptomyces strain is stronger towards F. o. dianthi, F. o. albedinis, and F. o. cyclaminis. It seems that the mycolytic power of N. dassonvillei is more specific to F. o. eleaidis, whereas the parasitism action varies depending on the "formae speciales" tested and the quantity of fungal mycelium produced. As a response to this parasitism, all the fungi produce resistance organs that can either be polymorphous thallospores or chlamydospores. The thallospores studied on a F. o. albedinis strain germinate faster than the microconidies of the same nonparasited fungus. However, many strains obtained from these thallospores are as susceptible as the mother strain to the antagonistic action of both actinomycetes
