Papp, V. (2015): Taxonomy and conservation status of the lignicolous basidiomycetes in Juhdöglő-völgy Forest Reserve. PhD dissertation - THESIS. PhD School of Horticultural Science, Budapesti Corvinus Egyetem, Budapest

The age or the naturality of the forest is often thought to be indicated by the structure of the forest; however, this does not necessarily shows the degree of biodiversity of the habitat. It is also possible to conclude the age of the forests by assessing the diversity of the different groups of organisms (e.g. mosses, insects, fungi). The presence or absence of some taxa, and the density of the populations may be markers for the indication of habitat naturality. One of these key groups is represented by the lignicolous macrofungi, considering that it is necessary to preserve the forests in their natural state for the presence and maintains of some taxa.
The list assembled by CHRISTENSEN et al. (2004) contains 21 lignicolous macrofungi species, and is widely used by the mycologists of several European countries as an indicator of the natural state of beech forests. Until now, 16 species from these have found in the core area of Juhdöglő-völgy Forest Reserve. Hence, the „ancient beech forest” habitat of the forest reserve, despite its small size, belongs to the most valuable beech forests of Europe, from the mycological point of view
