Furtadoa biseptata
Furtadoa biseptata Costa-Rezende, Drechsler-Santos & Reck 2017, in Costa-Rezende et al., Persoonia -Molecular Phylogeny and Evolution of Fungi, 39(1), 254-269 (2017)
Etymology: The species epithet refers to the two different septa in the generative hyphae that compose the context of the species.
Diagnosis: This species differs from F. brasiliensis by its thinner basidiomata, darker context, and the presence of simple septate generative hyphae in the context. 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 1 600 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-.
