The effects of liming on the composition of the mycoflora of dead,
lying wood in a Scots pine stand on acid, nutrient-poor soil was
studied after 5 yr. Liming led to a significant increase in species
number. Amphinema byssoides, Hyphoderma puberum, Hyphodontia
breviseta, Hypochnicium geogenium, and Sistotrema
octosporum significantly increased, whereas Botryobasidium
subcoronatum and
Trechispora farinacea significantly decreased after liming. The
proportion of species that are characteristic for coniferous wood
decreased, whereas the proportion of indifferent species and species that
are characteristic for deciduous wood increased after liming.
Explanations for this species shift are discussed and an increase in
nitrogen dynamics in the wood is considered the most plausible
explanation. Possible ecological consequences of these changes in
species composition are briefly discussed.
