“…The confirmed presence of potential spalting fungi in the Amazon could increase the use of undervalued wood in the region, if education of its global economic benefits could be achieved. As current research in spalting fungi is showcasing the industrial potential of fungal pigments applied into inks [67], dyes [68], textiles [69], solar energy [70] as well as woodcrafts [26]. Should this occur, it could help protect this endangered ecosystem by giving additional value to the decayed wood from the native forests, thus generating more revenue from forestland versus land use change to agriculture or grazing.…”

“…From zone-lines to green pigment, artwork that used this wood is still brilliantly pigmented, showing the long-lasting properties of the colors produced by these fungi [21][22][23][24]. Spalted wood is currently popular for woodwork where its unique aesthetics attracts customers [25] that are willing to pay premium prizes for it, classifying spalted wood as a value-added wood product [26].…”

Exploratory Sampling of Spalting Fungi in the Southern Peruvian Amazon Forest

Most of the research related to Peruvian Amazon fungi is focused on edible mushrooms and pathogens. Other important fungi, such as the spalting type (decay fungi that pigment wood internally), are not broadly studied, as most of them do not produce fruiting bodies and can be difficult to locate. Spalting fungi, however, are of broad economic importance due to their ability to produce pigments that enhance wood aesthetics, resulting in an increased economic value. In order to begin understanding the diversity of spalting fungi within certain regions of the Amazon, a sampling of downed trees and branches (through the opening of the xylem to identify potential pigmenting and zone line producing fungi) was done in the district of Las Piedras, Madre de Dios, Peru. Fungi suspected of causing internal pigment and zone lines were collected, cultured, isolated, and sequenced. The species found belonged to the orders Helotiales, Xylariales, Hypocreales, Russulales, Polyporales, Botryosphaeriales and two specimens of the class Leotiomycetes. The fungi collected produced pigments or zone lines in wild conditions and all of them were capable of wood decomposition. Interestingly, these are the same orders and genera as North American spalting fungi, which may indicate a correlation within species that pigment wood. The results obtained start a specific database of spalted fungi in the Amazon and, with it, help support an effort to increase the forest value of ecosystems primarily used for a few high-valued tree species.

“…Historically, wood stained by pigmenting fungi has been the most valued, especially the blue-green wood stained by fungi from the genus Chlorociboria. This wood was especially valued in continental Europe from the thirteenth to eighteenth centuries (Robinson et al 2016), and was often used in natural scenes made using intarsia, a form of inlay (Blanchette et al 1992;Michaelsen et al 1992;;Robinson et al 2016;Vega Gutierrez and Robinson 2020).…”

“…Its primary role in the ecosystem is as a pathogen of ganoderma mushrooms, however, it can also colonize wood and leaves behind a deep yellow pigment (Robinson, Tudor et al 2014). Its use in the art of spalted wood is limited, although it is gaining popularity (Vega Gutierrez and Robinson 2020). Like many other pigment-type spalting fungi (Tudor et al 2013), the colour produced changes over time, however, the degree of change, in terms of colour variation, has never been fully explored for S. ganodermophthorum.…”

The use of wood coloured by fungi, or 'spalted' wood, stretches back to the Renaissance. Most of this work was restricted to shades of blue-green, brown, white, and black zone lines. Modern spalting has added in shades of red and blue. The current colour palette of spalting fungi has the potential to be expanded through the use of Scytalidium ganodermophthorum, a fungal pathogen and suspected soft rot of wood, which produces multiple colours of pigment throughout its growth, including yellow and purple. However, no previous study has tracked colours of the extracted fungal pigment across time. This study showed significant colour change of extracted fungal pigments across 36 weeks of growth, transitioning over time from bright yellow to green shades, before finally becoming slate purple. This diversity of hues increases the colours available to artists working with spalting pigments, and has the potential to expand the art form.
