Polypore survey of Finland 4. Phaeolus, Fistulina, Ganoderma and Ischnoderma

Abstract

The Finnish distribution is mapped for five polypore species. Phaeolus schweinitzii (Fr.) Pat. has rare occurrences almost throughout the country, mainl y on Larix sibirica and Pinus sy/vestris. Fistu!ina hepatica Schaeff.: Fr. is strictly Hemiboreal , growing on Quercus robur and (one record) Castanea sativa. Ganoderma lipsiense (Batsch) Atk . (G. app!anatum) is a polyphagous saproparasite, common in the Hemiboreal and Southern boreal zones and rarer in the Middle boreal zone. Ganoderma lucidum (Curt.: Fr.) Karst. fa vours large stumps of Alnus glutinosa and has rare occurrences in the Hemiboreal and Southern boreal zones only. Ischnoderma benzoinum (Wahl.) Karst. is distributed over the whole of Finland , but is common only in the south. It grows mostl y on Picea abies, less often on Pinus sylvestris, and exceptionally on a few other hosts. None of these fungi cause notable economic losses as decaying agents.

Occurrence and decay patterns of common wood‐decay fungi in hazardous trees felled in the Helsinki City

“…The population study here, based on DNA fingerprinting, supports the field observations that G. lipsiense is the dominant species of Ganoderma in Finland (e.g. Niemelä and Kotiranta 1986;Niemelä 2005). It seems to be genetically uniform in northern Europe, and separate from Ganoderma sp.…”

Effect of Strain, Wood Substrate and Cold Treatment on the Yield and β-Glucan Content of Ganoderma lucidum Fruiting Bodies

“…Surprisingly, the maximum yield and biological efficiency of 90.2 g and 9% were achieved with the poplar wood-based substrate. In Finland, G. lucidum has not been reported growing in P. tremula in nature [ 35 ]. Higher biological efficiencies, 22.6% (alder sawdust supplemented with gram flour) and 20.7% (oak sawdust supplemented with corn bran), respectively, were obtained by Gurung et al [ 7 ] and Erkel [ 14 ].…”

“…Considering that the nature of phenolics in deciduous species differs from conifer species, their composition and structure could be expected to have a different effect on fungal metabolism [ 45 ]. Since P. tremula is not a typical host species for G. lucidum in Finland [ 35 ], it is possible that wood substrate based on this species causes stress to G. lucidum . Other wood components such as lignin, cellulose and hemicellulose fractions [ 9 , 27 ], fatty acids [ 22 ] and resin acids [ 11 , 46 ], among others, could also play a role in fungal polysaccharide production.…”

“…Its distribution is sporadic and it is commonly found in coastal areas [ 35 ], but the species can also be found inland; the northernmost findings are above the Arctic Circle [ 36 ]. In Finland, G. lucidum has been found in stumps of Alnus glutinosa , Betula sp., P. abies , Quercus robur and P. sylvestris [ 35 ]. Currently, the cultivation of G. lucidum in Finland is still in its infancy.…”
