FUNGI AND LICHENS IN THE BALTICS AND BEYOND XVIII ...

different fungal species of the same genus can infect the same host. Thus both Phomopsis
vaccinii and P. conorum can infect Vaccinium spp. Phylogenetic analysis revealed
relationship of teleomorph species Diaporthe angelicae and asexually reproducing fungi like
Phomopsis diachenii, P. foeniculi and some newly isolated Phomopsis spp. from
umbeliferous crops in Bulgaria and Lithuania.

Agaricoid fungi strongly react to various factors influencing forest ecosystem,
therefore they are good disturbance indicators. The aim of this study was to investigate the
influence of a piscivorous bird colony on diversity of above- and below-ground agaricoid
fungus complexes. The study was carried out in pine forest affected by a nesting colony of
continental subspecies of great cormorants (Phalacrocorax carbo sinensis) in the Curonian
Spit, Western Lithuania. Eighteen permanent study plots were established in the forest with
different degree of damage. Both above- and below-ground agaricoid fungus species diversity
and diversity of trophic groups was higher in the plots outside the colony. The lowest
diversity of trophic groups was observed in the plots with highest nest density and in the
higher elevated colony centre already abandoned by nesting birds. The depauperation of
trophic group diversity in these plots was mainly at the expense of soil saprobes and
mycorrhizal fungi. Notably, living ectomycorrhiza was still found in plots with high numbers
of nests, provided there were still living trees present, though no fruit bodies of
ectomycorrhizal species were found.

Lophodermium seditiosum Minter, Staley & Millar is one of the most significant
conifer pathogens in European forest nurseries and plantations. A number of chemical defence
agents is widely used for disease control but it would be valuable to produce an effective
biological control agent for seedling protection against L. seditiosum. Growth rate of L.
seditiosum mycelia on malt agar media with addition of pine or spruce bark and needle
extracts were tested in vitro. To add the extract sterile filter papers (ø 7 cm) impregnated with
certain extract were used.
