Phylloplane Fungi

Forty-nine species and 20 genera were collected irora the phyllosphere and phylloplane of wheat plants on 1% glucose and 50% sucrose-Czapek's agar at 28°C. The total counts of phyllospbere and phylloplane fungi displayed seasonal periodicities and the highest counts were found in April and May 1977, 1978. In the case of phyllosphere the most frequent species were <i>Aspergillus niger, Penicillium corylophilum</i> and <i>Alternaria alternata</i>; in the phylloplane <i>Aspergillus niger</i> and <i>A. flavus</i>.

Poplar Leaves

The microfungal succession on the surfaces and interior of attached aspen poplar leaves was followed throughout a growing season at three heights in the tree canopy using a number of isolation and observational techniques. The fungal succession on and within the leaves was in general similar to that reported for other angiosperm leaves. The outer sheathing bud scales were colonized by a limited range of fungi, but the enclosed leaves were free from fungal colonization. The adaxial surfaces of young newly expanded leaves were sparsely colonized by fungi. As the leaves matured they were extensively colonized by the common phylloplane fungi (pink and white yeasts, Aureobasidium pullulans, Cladosporium spp., Alternaria alternata, and Epicoccum purpurascens) especially on the adaxial surface. At senescence both leaf surfaces had extensive hyphal growth on them and a greater internal colonization by phylloplane fungi had occurred. Common phylloplane fungi were less frequently isolated from freshly fallen leaves than from the senescent leaves, but a sterile dark species was frequently isolated from within them. The height of the leaves in the canopy was shown to influence the mycoflora of the aspen poplar leaves, with certain species (the yeasts, Aureobasidium pullulans, Cladosporium spp., and Botrytis cinerea) showing changes in their frequency with sampling height.

Conifer Needle

Fungi (ca. 2000 isolates) were isolated from balsam fir needles infested by the spruce budworm (Choristoneurafumiferana Clem.) as well as from uninfested needles. Most of the isolates were well-known colonizers of the conifer needle phylloplane. However, approximately 6% of the isolates obtained from the infested needles were unusual needle phylloplane fungi and some of these were toxigenic and (or) pathogenic. Some isolates (23) associated with the needles, frass, and larvae were cultured; solvent extracts of the freeze-dried material of some of these were cytotoxic to HeLa 229 cells. The isolates showing cytotoxicity were grown and the resulting hyphae were incorporated (1%, w/w) into a spruce budworm diet. Hyphae from several isolates in these diets resulted in slower growth rate and mortality. The results of this study show that the presence of the spruce budworm altered the phylloplane mycoflora and the data suggest that there are toxic effects to spruce budworm that consume phylloplane fungi.
