“…The weakly active cibaric acid and (8E)-1 0-hydroxydec-8-enoic acid from Cantharellus fruiting bodies may protect the fungus from nematode feeding, which would be an explanation for their occurrence in injured specimens (6). Both fatty acids did not show antimicrobial, cytotoxic and phytotoxic effects.…”

In a screening for nematicidal activities in cultures of Basidiomycetes, cultures of Pleurotus pulmonarius and Hericium coralloides exhibited toxic effects towards the saprophytic nematode Caenorhabditis elegans. Subsequently S-coriolic acid (1), linoleic acid (2), p-anisaldehyde (3), p-anisyl alcohol (4), 1-(4-methoxyphenyl)-1,2-propanediol (5), and 2-hydroxy-(4'-methoxy)-propiophenone (6) were isolated from submerged cultures of P. pulmonarius. All compounds showed nematicidal activities towards C. elegans. The most active compounds were 1 and 2 with LD50 values between 5 and 10 ppm. Compounds 1, 4, and 5 have not been previously isolated from higher fungi, 6 is a new natural product. From cultures of H. coralloides, which exhibited both repellant and nematicidal effects, a nematicidal fatty acid mixture was obtained, containing linoleic acid, oleic acid, and palmitic acid as its main components.

“…107 In fungi, upon injury, linoleic acid is oxidised and degraded via the intermediate (8E,12Z,10S)-10-hydroperoxy-8,12-octadecadienoic acid (37) to (3R)-1-octen-3-ol (38) and (8E)-10-oxodec-8-enoic acid (39) (Scheme 1). 32,108 (8E)-10-oxodec-8-enoic acid (39) has been found in increased amounts in wounded fruiting bodies, [109][110][111] for instance in Marasmius oreades, and seems to stimulate mycelial growth and stipe elongation in Agaricus bisporus. 112 Both (3R)-1-octen-3-ol (38) and (8E)-10-oxodec-8enoic acid (39) exhibit antifungal activities.…”

Fungi are widespread in nature and have conquered nearly every ecological niche. Fungi occur not only in terrestrial but also in freshwater and marine environments. Moreover, fungi are known as a rich source of secondary metabolites. Despite these facts, the ecological role of many of these metabolites is still unknown and the chemical ecology of fungi has not been investigated systematically so far. This review intends to present examples of the various chemical interactions of fungi with other fungi, plants, bacteria and animals and to give an overview of the current knowledge of fungal chemical ecology.

“…Changes in bioactivity and/or chemical composition as a response to injury are known in basidiomata (Sterner et al 1985;Pang et al 1992;Wood et al 1994Wood et al , 2001Stadler and Sterner 1998;Fäldt et al 1999). In some cases, these changes are thought to serve as a chemical defense system against fungivores (Sterner et al 1985;Stadler and Sterner 1998;Wood et al 2001).…”

Repellency of injured ascomata of Ciborinia camelliae and Spathularia flavida to fungivorous collembolans

The repellency of injured ascomata of Ciborinia camelliae and Spathularia flavida was tested with the collembolan Ceratophysella denisana, a common mushroom feeder. Presentation of a test ascoma (intact or injured) at a distance to a collembolan that was feeding at a bait showed that significantly more collembolans moved away in response to the presentation of injured ascomata than intact ones for both species. These results suggest that the ascomata of these species showed repellency to the collembolan species as a response to injury. Odor is speculated to be one of the stimuli eliciting the behavioral responses observed.
