Geesterania carneola
Geesterania carneola (Bres.) Westphalen & Rajchenb. 2018, in Westphalen et al., Persoonia-Molecular Phylogeny and Evolution of Fungi, 41(1), 130-141 (2018).
Diagnosis: It is characterized by its yellowish basidiomes that become reddish when bruised and sometimes after drying and the large and very irregular pores (3–5 per mm) that are often split and lacerate, forming a daedaloid surface. Microscopically it presents a dimitic hyphal system, thin to thick-walled cystidia encrusted with fine crystals and narrowly ellipsoid basidiospores (4.0–5.0 × 2.0–2.5 μm, Lm × Wm = 4.38 × 2.38, Q = 1.60–2.25, Qm = 1.86, n = 30/2)
Index Fungorum Number: IF822659
Notes: This species was described from southern Brazil (Santa Catarina State) by Bresadola (1896) and since then registered from different tropical and subtropical regions in South and Central America (Lowe 1966, Carranza-Velásquez & Ruiz-Boyer 2005, Robledo & Rajchenberg 2007, Westphalen et al. 2012).
