“…Therefore, it is no wonder that in spring samples we found only the spores of Elaphomyces, which has rather robust sporocarps that could overwinter or even start to develop early in the spring. Blaschke and Bäumler [15] also found seasonal differences in mycophagy of Myodes glareolus and Apodemus flavicollis in Germany, with a relatively small amount of spores in excrements during springtime. In subalpine conifer forests in Italy, the spring pellets of Sciurus vulgaris contained spores not only of Elaphomyces but also of four other taxa of hypogeous fungi [13].…”

“…Nevertheless, hypogeous fungi predominated in the small mammal diet in all studied forest communities. Other studies have demonstrated that the spores of hypogeous fungi could predominate in the excrements or stomach contents of various animals [3,13,15]. Maser and colleagues [4] suggested that the olfactory keenness of mycophagous mammals is the main reason why the mammals looks for the fungi and enable them to locate hypogeous sporocarps precisely and dig them out with minimal waste of effort.…”

“…Little is known about the mycophagy of these mammals in European forests, especially in the hemiboreal and boreal forests of the Baltic and Fennoscandian regions. The diets of M. glareolus and A. flavicollis have been investigated in high and low-elevation forests of Bavaria in Germany [15], and the Myodes glareolus diet has been studied in Finland [16]. The mycophagy of insectivorous animals, e.g.…”

The diets of small mammals in different hemiboreal spruce-dominated, oak-dominated and mixed forests in western part of Lithuania were studied by examination of fungal spores in fresh fecal pellets of caught animals. In the diets of mice (Apodemus spp.), bank voles (Myodes glareolus), and common and pygmy shrews (Sorex araneus and S. minutus), 22 different fungal taxa were identified, 15 of which were hypogeous fungi. The sporocarp abundance and the spores in fecal samples of Elaphomyces fungi prevailed in study area during this investigation. Although most of the captured individuals consumed fungi, the consumption varied among small mammal species. The data show that the fungi were more frequent and taxonomically diverse in Myodes glareolus than in Apodemus spp. diets. The study provided evidence that the fungal component in the diets of insectivorous Sorex species is more diverse than previously known. The availability of sporocarps and the fungal component in the diets of small mammals showed seasonal effects. Annual hypogeous and epigeous sporocarp abundances did not vary significantly across forest types. The significant difference in mycophagy was observed across all forest cover types, with the greatest fungal diversity in fecal samples collected in mixed coniferous-deciduous tree stands.

“…Spores of Octaviania species have frequently been recorded in the fecal pellets of rodents (Bennet, Baxter 1989;Blaschke, Bäumler 1989;Mcintire, carey 1989;claridge, Lindenmayer 1998). The animals are possibly attracted by the odour produced by gasterocarps, and easy to detect in fresh, cut specimens.…”

“…Therefore, fruit body fungivory matters only while fruit bodies are functional (producing, maturing or discharging spores) rather than when they become dysfunctional and senescent. Some studies have shown that fungivores, mainly mammals, contribute significantly to the dispersion of spores of consumed fruit bodies (Kotter & Farentinos, 1984 ;Blaschke & Baumler, 1989 ;Cazares & Trappe, 1994 ;Johnson, 1995Johnson, , 1996Reddell et al, 1997). Also, at least some of these mammal fungivores facilitate spore germination by partially digesting the spore wall (Durrieu et al, 1984 ;Lescourret & Ge!…”

Effects of fungivory by two specialist ciid beetles (Octotemnus glabriculus and Cis boleti) on the reproductive fitness of their host fungus, Coriolus versicolor

On the basis of the evidence that insect fungivory has the potential to affect fungal reproductive fitness, we investigated the effects of two specialist ciid beetles (Octotemnus glabriculus and Cis boleti) on the reproductive potential of their host fungus, Coriolus versicolor. We found, from field data, a negative correlation between the number of individuals of O. glabriculus inhabiting C. versicolor fruit bodies and the percentage of the fungal spore‐producing surface (hymenium) that was functional. By contrast, the number of C. boleti inhabiting C. versicolor fruit bodies did not correlate with the percentage of functional hymenium. Experimentally, O. glabriculus and C. boleti reduced the reproductive potential of C. versicolor by 58% and 30%, respectively, whereas the combined trophic activity of both beetles caused a reduction of 64%. This latter effect was not significantly different from that caused by O. glabriculus alone. These findings disagree with previous assertions that insect fungivory on fruit bodies has only neutral effects on fungal fitness. We conclude that in the short‐term, fungivory by ciids significantly decreases the area of functional hymenium of C. versicolor and is likely to reduce fungal reproductive fitness. Within this perspective the evolution of certain fungal characteristics (i.e. chemical composition, consistency and phenology) can be interpreted as being driven by fungivory.
