DESCRIPTION Basidiome perennial, gregarious, cespitose; varying in shape from dimidiate, dimidiate elongated, semicircular, with attack on the substrate ranging from strongly adhered to semistipitate, 67 - 115 mm diameter × 47 - 66 mm width × 4 - 5 mm thickness, soft and malleable when young, coriaceous with age. Pileus surfacecrusty to smooth, velvety to tomentose, bluish, slightly glossy to opaque, orange (N 00 Y 90 M 60) to matt orange (N 00 Y 99 M 60), and the whole surface becomes yellowish white (N 00 Y 20 M 00) at high temperatures and in older specimens. Margin thick, acute to obtuse, entire to irregular, concolor to pileus surface, or pale orange (N 00 Y 80 M 50). Context and pileus surface form distinct layers in cross-section, fibrousand softcompact, 2 - 3 mm thick, non-homogeneous zones, predominantly brown (N 60 Y 99 M 70), sometimes merged with orange (N 00 Y 90 M 60) and cream (N 00 Y 40 M 10) zones, with homogeneous orange (N 00 Y 90 M 60) and cream (N 00 Y 40 M 10) zones in A the apical portion, reflecting the developmental stage. Line grayish brown (N 60 C 00 M 10) and cream (N 00 Y 40 M 10), between the context and the hymenophore. Surface of the pores of the hymenophore bright orange (N 00 C 90 M 60) to moderate reddish orange (N 00 C 90 M 80); pores circular, angular to irregular, 3 - 5 pores per mm, 0.2 × 0.3 mm diameter; dissepiment thin, entire or lacerated, concolor to the pore surface; tube circular with 1 layer up to 2 - 2.5 mm deep, about 0.4 mm wide, light orange (N 00 C 80 M 50). Macrochemical reaction occurs when adding 5 % KOH resulting in a rapid color change from black to greenish brown in part of the basidiome. Hyphal system trimitic.

Basidium clavate, 10 - 16 × 5 - 7 µm, with basal clamp, four sterigmata, hyaline in 5 % KOH, CB-; IKI-. Basidiospores 5.72 - 7.96 × 3.06 - 4.83 µm (x = 6.92 ± 0.6 × 4.01 ± 0.5; Qm = 1.7), elongated, smooth, slightly curved, hyaline in 5 % KOH, CB-; IKI-. REMARKS There is little clarity on the taxonomic value of some morphological characters, such as the presence of a line between context and hymenophore observed in Pycnoporus amazonicus Gurgel & T. S. Cabral, sp. nov. This characteristic is observed below the pileipellis, sometimes in Trametes betulina (L.) Pilát, T. hirsuta (Wulfen) Lloyd, and T. versicolor (L.) Lloyd, and always in the clade meyenii (Welti et al. 2012). On the other hand, the absence of a black line below the pileus, allied to a glabrous upper surface, and the absence of parietal crystals were diagnostic characteristics used to recognize Leiotrametes Welti & Courtec. (synonym of Cubamyces Murrill) (Justo & Hibbett 2011; Welti et al. 2012). For the species within Pycnoporus, this characteristic was shown to be delimitative, and we report the presence of this characteristic for the first time in specimens of the genus. When compared to other species in the genus, P. sanguineus has a smooth, zoned pileus, 5 - 8 pores per mm, context with alternating white and medium orange, scaly to cottony zones, and P. coccineus has a smooth pileus, pores 3 - 5 per mm, and a context of a pale color, with predominant zones alternating from white to moderate orange (Nobles & Frew 1962, lectotype analysis), while P. amazonicus Gurgel & T. S. Cabral, sp. nov. has a smooth to tomentose pileus, 3 - 5 pores per mm, and a context sometimes not visible, predominantly brown, with a grayish line between the context and the hymenophore. With respect to the other two species of the genus, P. cinnabarinus has a thicker basidiome (170 mm), 1 - 4 circular pores per mm (Nobles & Frew 1962, lectotype analysis), and P. puniceus has a well-supported morphology and phylogeny, with a cinnabar pileus, 1 - 3 irregular pores per mm and a context with intense and lighter cinnabar zones (Nobles & Frew 1962; Ryvarden & Johansen 1980; lectotype analysis). Thus, the morphological characteristics of colours and appearance of the context allied to the presence of a line between the context and the hymenophore and the numbers of pores per mm present in the hymenophore, together with the phylogenetic position within Pycnoporus, forming strongly supported clades in two of the phylogenies (Figs 3; 4), provide evidence that Pycnoporus amazonicus Gurgel & T. S. Cabral, sp. nov. is a distinct species.	en	F., Rafaela Araújo, S., Gurgel Catarina, Leimi, Carvalho Dirce, De, Komura Ruthe, Dalman, Jesus Santos, De, Isadora Fernandes, Vargas-Isla, França Ruby, Ishikawa, Noemia Kazue, Cabral, Tiara Sousa (2025): A new species and a new record for Pycnoporus P.

B37B87C66E53FFB55D43F8BCD941F904.taxon	description	SUBSTRATE. — Grows on various types of deadwood, mainly in open sunny places. DESCRIPTION Basidiome annual to perennial, solitary, gregarious to cespitose; ranging from dimidiate, flabelliform, spatulate, semicircular, infundibuliform, with attack on the substrate ranging from strongly adhered, semiestipitateto stipetate, 70 - 124 mm diameter × 47 - 85 mm width × 2 - 4.5 mm thick, coriaceous. Stipe 6 - 19 mm width × 2 - 4 mm thick, solid, concolor to pileous. Pileus surface coriaceous when damp, becoming stiff when dry, velvety and glossy when young, glabrous and striated with age, reddish orange (N 00 Y 99 M 90) to vivid orange (N 00 Y 90 M 70), with alternating zones of yellowish white (N 00 Y 20 M 00) to orange (N 00 Y 90 M 60), becoming yellowish white (N 00 Y 20 M 00) over the entire surface at high temperatures and when old. Margin thin, acute, entire to irregular, sometimes tomentose, yellowish orange (N 00 Y 99 M 50) to whitish yellow (N 00 Y 20 M 00). Context and surface of the pileus continuous in cross section, floccose to fibrous, shiny, 1.4 - 3 mm thick, pale yellow (N 00 Y 30 M 00) and light orange (N 00 Y 80 M 40) zones, radially separating, reflecting the stages of development. Linebetween the context and the hymenophore sometimes present, pale yellow (N 00 Y 30 M 00). Surface of the pores of the hymenophore intense reddish orange (N 00 Y 99 M 90) to moderate reddish orange (N 00 Y 90 M 80); pores circular to angular, tomentose and serrated walls, 5 - 8 pores per mm, 0.1 × 0.3 mm diameter; dissepiment thick when young, becoming thinner with age, concolor to the pore surface; tube circular, 1 - 2 layers 1 - 1.5 mm deep × 0.3 mm wide, light orange (N 00 Y 80 M 00) and whitish yellow (N 00 Y 20 M 00). Macrochemical reaction occurs when adding 5 % KOH, resulting in rapid color change from black to greenish brown in part of the basidiome. Hyphal system trimitic. Pileus surface similar to the context. Context composed of generative hyphae thin-walled, with frequent clamps, rarely branched, 1 - 4 µm diameter, hyaline to yellowish in 5 % KOH, CB-; IKI-; skeletal hyphae dominate, straight or slightly tortuous, thick-walled, unbranched, 2 - 6 µm diameter, hyaline to yellowish in 5 % KOH, non-cyanophilous and non-amyloid; binding hyphae thick-walled, non-septate, branched with short branches, 2 - 3 µm diameter, yellowish in 5 % KOH, CB-; IKI-. Trama of the tubes composed of hyphae similar to the context. Hyphae with orange crystals predominate in all parts of the basidiome, 2 - 4 µm diameter, hyaline in 5 % KOH, CB-; IKI-. Basidium clavate, 11 - 15 × 5 - 6 µm, with basal clamp, four sterigmata, hyaline in 5 % KOH, CB-; IKI-. Basidiospores 4.02 - 5.96 × 1.58 - 3.62 µm (x = 4.79 ± 0.5 × 2.5 ± 0.4; Qm = 1.9), elongated, smooth, slightly curved, hyaline in 5 % KOH, CB-; IKI-. REMARKS This species presents basidiomata whose characters, such as pileus colours, texture and zoning, change depending on environmental conditions. These changes can lead to misidentifications, especially with morphologically similar species, such as P. coccineus, which has an orange to reddish-orange basidiome and areas with colors similar to the pileus. Pycnoporus coccineus differs from P. sanguineus by having a basidiome with a soft aspect and 3 - 5 pores per mm with thick walls. Pycnoporus sanguineus has an ample worldwide distribution, as can be observed by the distribution of its sequences in the phylogenies of ITS (Fig. 4) and, for Brazil, it can be found in almost all states, of which here we report a new record for the state of Roraima.	en	F., Rafaela Araújo, S., Gurgel Catarina, Leimi, Carvalho Dirce, De, Komura Ruthe, Dalman, Jesus Santos, De, Isadora Fernandes, Vargas-Isla, França Ruby, Ishikawa, Noemia Kazue, Cabral, Tiara Sousa (2025): A new species and a new record for Pycnoporus P.
