Abstract
Ganoderma resinaceum Boud. is commonly found in Mediterranean region, but rarely in Western, Central or Eastern Europe. It is a parasitic basidiomycetous fungus causing stem decay—especially in urban trees. A collection of nine fungal specimens from Slovakia (Central Europe), morphologically identified as G. resinaceum, was recently studied on the basis of sequence data from the internal transcribed spacer (ITS) regions. Analyses showed that the collections clustered into two separate groups. In this study—for the first time—the sequences of other molecular markers, namely partial translation elongation factor (tef1-α) region and partial 25S large subunit ribosomal RNA gene (25S LSU rRNA), as well as matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI–TOF MS) were obtained and used to evaluate the genetic variability of G. resinaceum. All these analyses confirm the existence of two previously unrecognized genotypes within the morphospecies.
Highlights
Ganoderma resinaceum Boud. (Polyporales, Basidiomycota) is a parasitic fungus, later a saprotrophic, preferring to live on broadleaved woody plants in synanthropic habitats in warmer parts of Europe [1].it is usually used as ethnomedicine for immunoregulation, hyperglycemia and liver disease in the Asian traditional pharmacopoeia [2] and in some parts of West Africa [3]
The same strains of Ganoderma resinaceum as in the study of Beck et al [6] and three new strains were used in the following analyses
G. resinaceum internal transcribed spacer (ITS) sequences within genotype B were practically identical, limited variability was observed among genotype A sequences

Some G. resinaceum basidiocarps may appear very similar to G. lucidum s. Some G. resinaceum basidiocarps may appear very similar to G. lucidum s. str., but they differ in terms of the ornamentation of the basidiospores [5,6]
