Based on comparison of molecular, morphological and ecological data, we propose that Hybogaster giganteus Singer, a parasitic basidiomycete on stem bases and coarse roots of Nothofagus in Chile, is conspecifically related to the sympatric Bondarzewia guaitecasensis. According to our concept, H. giganteus is representing a sequestrate form of the la...

Purpose The study aims to test the color fastness of wool and linen fabrics dyed by simple immersion in ethanol dissolutions of fungal dyes. Design/methodology/approach Ethanol dissolutions of Talaromyces australis and Penicillium murcianum dyes were prepared to a concentration of 0.3% and used to dye wool and linen samples by immersion. Color fas...

Cortinarius magellanicus Speg. is an edible, ectomycorrhizal fungus, widely distributed in Argentina, Chile and New Zealand. However, earlier studies already indicated that the epithet ‘magellanicus’ might have been applied in a wide sense, thus circumscribing several species. A neotype was designated by Moser and Horak (1975) due Spegazzini's type...
Article
Natural dyes and pigments have been proposed as an eco-friendly alternative to artificial pigments. Among the diverse organisms able to synthesize natural dyes and pigments, several wood inhabiting fungi produce extracellular compounds which have been tested to dye fabrics at laboratory conditions with good results. However, the dyeing conditions u...

Fungal isolates obtained from rotten wood samples were identified and selected by their ability to produce fungal dyes in liquid media. Fungal isolates produced natural extracellular dyes with colors ranging from red to orange, yellow and purple. Dyes from two of these fungi, Talaromyces australis (red) and Penicillium murcianum (yellow), were extr...

Due to the increasing emergence of resistance of bacterial pathogens to current antibiotics, we have examined the marine fungi present in sea sediments obtained 200 m offshore to discover new antibacterial compounds active against multidrug-resistant bacteria. One strain, identified as Emericellopsis minima, was isolated from sediments of Talcahuan...

Fungal pigments from spalting fungi Scytalidium cuboideum (red), Scytalidium ganodermophthorum (yellow) and Chlorociboria aeruginosa (green), were used to attenuate the presence of blue sap-stain in Pinus spp. samples. Pigments, filtered from liquid cultures of spalting fungi, were vacuum impregnated into pine samples with three different levels of...

Chile is host to several types of temperate forests, many of which are plantations of moderate- to low-value woods. In an effort to explore potential methods of adding value to radiata pine and southern beech, these woods were inoculated with native Chilean fungi to determine if spalting could be induced under a reasonable time frame. Results showe...

... Species of these two genera are putatively the result of the same sequestration event (Smith et al. 2013, Sanchez-García et al. 2020 confirming the phylogenetic pattern expected under progenesis. The case of Hybogaster, recently confirmed as a "sequestrate" form of Bondarzewia guaitecasensis (Palfner et al. 2020), might constitute a phenomenon other than sequestration since the contortion of the hymenophore is not associated with enclosure, but rather to an abnormal proliferation and folding, and it seems to be associated with latitude and temperature gradients. The position of many other taxa such as Mycolevis and Leucophelps (among others) is still doubtful due to their unresolved phylogenetic relationships and lack of information on the structure and ontogeny of their fertile tissues. ...
... P. murcianum and T. australis, isolated from decay wood in forest of central-south Chile, have demonstrated to be efficient pigment producers. The pigments from these two fungal species have already been used in the dyeing of fabrics for textile purposes (Hernández et al. 2018a(Hernández et al. ,b, 2019(Hernández et al. , 2020, but they have not yet been chemically characterized. ...
... When we refer to the transfer of knowledge or R&D results, we mean actions that try to facilitate the use, application and social and economic innovation of the new knowledge and technological development derived from research. Investigations undertaken with wild fungi include the identification of more than 30 edible species from native forests, grasslands and forest plantations, describing their organoleptic properties Toledo et al., 2016a;Barroetaveña & Toledo, 2020), analyzing their taxonomy and phylogeny (Rajchenberg, 2006;Pildain et al., 2014;Salgado Salomón et al., 2018Pildain et al., 2019;González et al., 2021;, their phenology, ecology and productivity Toledo et al., 2014;Barroetaveña & Toledo, 2020;Pildain et al., 2021), their nutritional and nutraceutical values (Toledo et al., 2016b;, features related to the domestication of cultivable species and "mycosilvicultural" management to increase their productivity (Solans et al., 2010;, the economy of trading and demand in local gastronomy (Fernández et al., 2012(Fernández et al., , 2020, and finally the sociocultural features of harvesters and the documentation of ancestral uses considering the associated processes of change (Valtriani et al., 2017;Molares et al., 2019). Investigations with cultivated mushrooms included the evaluation and selection of lignocellulosic substrates from waste available in Andean Patagonia (Roggero Luque et al., 2021, 2022, testing preservation techniques in order to extend their fresh commercialization window (Ohaco & Barroetaveña, 2018), and the enriching of the culture collection with strains of native, wood degraders species (Fistulina antarctica, Fistulina endoxantha, Grifola gargal, Ganoderma australe and Aleurodiscus vitellinus) to develop their cultivation protocols. ...
... species produce anthraquinones with antimicrobial activity and UV protection property [7]. According to Hernández et al. study, wood-inhabiting fungi Penicillium murcianum and Talaromyces australis for yellow and red pigments, respectively, were used and they stated that these pigments have a great potential because of good color fastness when applied on wool [28]. Mussagy et al. reported the usage potential of the yeast Phaffia rhodozyma as a natural astaxanthin source for textiles [29]. ...
... Furthermore, Talaromyces australis, Penicillium murcianum, Talaromyces sp., Trichoderma spirale, and Fusarium oxysporum, were recorded for various natural pigments production when grown in liquid media. [47] The produced pigments by filamentous fungi are secondary metabolites whose production usually commences late in the growth of the microorganisms, especially when entering the stationary phase [48]. ...
... [12][13][14]. To date, research on the bioactivities of secondary metabolites from Emericellopsis sp. has focused on their anti-inflammatory, antibacterial, and antitumor activities [12,13,[15][16][17][18], but few studies have investigated their antithrombotic activity. ...
... Bleaching treatments for bluestained lodgepole pine was carried out by Evans et al. (2007), who found that sodium hypochlorite was effective at removing the blue-color from blue-stained wood, but it was less effective at restoring the lightness of the treated wood. Hernandez et al. (2016) impregnated blue-stained pine wood using fungal pigments from spalting fungi and found that the fungal pigments were suitable for attenuating the appearance of the blue stain on the wood surface. Yu et al. (2010) reported that the combination of compression and heat PEER-REVIEWED ARTICLE bioresources.com ...
... Mold fungi have traditionally been separated from decay fungi, although there is significant overlap between the two groups, particularly within the classification of soft rots (fungi that selectively decay the wood cell wall and cause localized damage) [26][27][28]. Specific pigments from soft rotting fungi are prized for their use in historic woodworks and are well known for their photostability. Unlike the stable blue-green of xylindein from the soft rotting fungi Chlorociboria species [15,[29][30][31] or the melanin of soft rotting Xylaria polymorpha [32][33][34], the stability of these more traditional 'mold' pigments is understudied. ...
