属：费塔多芝属Furtadomyces

宏观形态特征：费塔多芝属物种子实体一年生，具侧生至近中生柄，软至木栓质。菌盖单片，圆形至扇形或漏斗形。菌盖表面黄褐色至灰褐色，不具漆状光泽，光滑至被绒毛，具明显的同心环状条纹或硬毛；菌肉白色至浅褐色，具暗色线，软木栓质。菌柄圆柱形，黄褐色，被绒毛，实心至空心；菌柄菌肉同质，浅褐色。菌孔面白色至稻草黄色，划伤无颜色变化；管壁薄至厚，全缘至撕裂；菌孔圆形至角形；菌管颜色略比菌肉暗。微观形态特征：费塔多芝属物种菌丝一至二型（菌髓二型，菌肉一型）；菌肉生殖菌丝无色，薄壁至略厚壁，具锁状联合、简单隔膜和一空心的顶端；菌管菌髓由具锁状联合的生殖菌丝和枝状分叉的骨架菌丝组成。囊状体和小囊状体缺失。担子棒形，具4小梗。担孢子近球形至椭球形，无色，具双层壁结构；孢子外壁具蠕虫状纹饰至网状纹饰；孢子内壁具柱状突起； IKI-。
讨论：菌孔面划伤不具血红色颜色反应，担孢子不具平截端、担子果质地较软和具两种类型的生殖菌丝以及菌肉为一型菌丝系统等特征是区别其他属的主要依据。
模式物种：Furtadomyces biseptatus双隔费塔多芝

新组合描述：
Basidiomata stipitate, pleuropodal, single; pileus 25–45 mm diam, up to 10 mm thick, almost flattened to slightly convex, soft when fresh, corky when dry; margin incurved and irregular, becoming strongly involute upon dried. Pilear surface greyish brown, azonate, radially finely strigose, wrinkled at the center, glabrous. Context corky, pale brown, homogeneous, 0.3–5 mm thick, thinner near the margin. Tubes slightly darker than context, up to 3 mm long. Pore surface concolorous to context; pores circular, 3–5(–6) per mm, (200–)250–400 µm diam, (mean = 358.2 µm); dissepiment entire, 90–230 µm thick, (mean = 155.9 µm). Stipe solid to hollow, straight to tortuous, up to 50 mm long and 5 mm diam; surface velutinous, longitudinally corrugated, pale brown; context with the same consistency and concolorous with pilear context. Pilear surface composed of generative hyphae, 4–7 µm diam, thin to slightly thick-walled, parallel to the contextual hyphae. Hyphal system mono-dimitic; context composed of two kinds of generative hyphae: one clamped to occasionally simple-septate, 3–7 µm diam, hyaline, thin to slightly thick-walled, straight to tortuous, branched; the second gloeopleurous-like, rarely simple-septate, with long stretches without septa (up to 1600 µm), 10–15 µm diam, hyaline, thin to slightly thick-walled, straight to tortuous, mostly unbranched, but eventually presenting some lateral short prolongations; trama of tubes composed of clamped generative hyphae, 3–5 µm diam, hyaline, thin walled; and arboriform skeletal hyphae with few apical, 4.5–6 µm diam in main stalk. Basidia subglobose to clavate, 4-sterigmate, 12–15 × 8–10 µm. Basidiospores subglobose to ellipsoid, ((6–)7–10 × (5.5– )6–8(–9) μm), (mean = 7.6 × 6.5 µm), Q = 1.07–1.33 (1.36), (mean-Q = 1.18), hyaline, double-walled with the inner layer finely and regular ornamented, verrucose under SEM, IKI-.
Notes — Furtadoa biseptata presents macro- and micromorphology that resembles Furtadoa brasiliensis, mainly differing by a thinner and darker pileus and by the presence of simple septa (Fig. 5). Furtadoa corneri differs from the new species by the funnel-shaped basidiomata and the thinner pileus, as well as by slightly larger basidiospores (8–10 × 6–8(–9) µm, mean = 8.2 × 7.4). Furtadoa biseptata was collected just once, even with several field expeditions across four years in the type locality, suggesting it to be a rare species.
