Interactions between the ectomycorrhizal fungus
Laccaria laccata and the soil fungus Trichoderma virens in
co-culture and in the rhizosphere of Pinus sylvestris seedlings
growing in vitro were investigated by light and scanning electron microscopy. The growth of T. virens was inhibited in
co-culture. Shortened, more branched and sometimes deformed or
injured hyphae of T. virens were observed in the zone of
inhibition. Two-month-old mycorrhizae of P. sylvestris/L.
laccata were inoculated with a conidial suspension of T. virens
and examined at intervals of 7-24 h and 2, 3, and 6 days
post-inoculation (p.i.). On non-mycorrhizal roots, conidia
germination was high and long hyphae formed 3 days p.i. On
mycorrhizal roots, short germ tubes were observed only
sporadically. At 3 days p.i., the mantle hyphae of L. laccata
grew towards the conidia and coiled around them. Extremely dense
coils of hyphae were found around clusters of conidia.
Deformation of conidia, breaks in conidial walls and their
partial degradation were observed 6 days p.i
