Fig. S1. Macroscopic (top) and microscopic (bottom) aspects of wood (E. cordifolia) after white rot (left) and brown rot (right) under environmental conditions in the Austral rainforest (Chiloe island, Chile). Wood after the selective and extensive removal of lignin (by G. australe) showed a soft fibrous texture and white colour being consumed by cattle as a natural feed (a); while the same wood after brown-rot decay (by an unidentified basidiomycete) exhibited a cubic appearance and reddish-brown colour (b). Light microscopy revealed selective lignin staining with safranin (d) while cellulose was stained with the Astra blue contrast dye (c). The bars (in c and d) correspond to 250 μm.

Fig. S2. Py-GC/MS of: (a) sound E. cordifolia wood; and (b) E. cordifolia wood degraded by a brown-rot fungus. The numbers refer to the lignin-derived compounds listed in Table S1. Letters refer to the polysaccharide-derived compounds: a, 2-methylfuran; b, hydroxyacetaldehyde; c, (3H)-furan-2-one; d, (2H)-furan-3-one; e, furfural; f, 2-hydroxymethylfuran; g, 2-acetylfuran; h, 2-methyl-2-cyclopenten-1-one; i, (5H)-furan-2-one; j, 2,3-dihydro-5-methylfuran-2-one; k, 5-methylfurfural; l, 4-hydroxy-5,6-dihydro-(2H)-pyran-2-one; m, 2-hydroxy-3-methyl-2-cyclopenten-1-one; n, 3-hydroxy-2-methyl-(4H)-pyran-4-one; o, 3,5-dihydroxy-2-methyl-(4H)-pyran-4-one; p, 5-hydroxymethyl-2-furfural; and q, levoglucosane.

Fig. S3. Py/TBAH of: (a) sound E. cordifolia wood; and (b) E. cordifolia wood degraded by a brown-rot fungus. The labels refer to the H-, G-, S- and MC-type lignin-derived compounds listed in Table S2, whose structures are depicted in Fig. S4.

Fig. S4. Structures of the p-hydroxyphenyl (H), guaiacyl (G), syringyl (S) and methoxycatechol (MC) lignin-derived compounds released after Py/TBAH of the sound and brown-rotted E. cordifolia wood (Fig. S3).

Table S1. Relative molar areas (%) of the compounds identified in the Py-GC/MS of the sound and brown-rotted E. cordifolia wood (Fig. S1).

Table S2. Relative molar areas (%) of the p-hydroxyphenyl (H), guaiacyl (G), syringyl (S) and methoxycatechol (MC) type lignin-derived compounds identified after Py/TBAH of sound and brown-rotted E. cordifolia wood (Fig. S2).
