Trametes suaveolens
Trametes suaveolens (L.) Fr. 1838., in Cui, et al., Fungal Diversity 97, 137–392 (2019)
Diagnosis: Basidiocarps annual, effused-reflexed to pileate, solitary or imbricate, with strong anise odor when fresh and gradually disappeared when dry, corky and distinctly light in weight when dry. Pilei semicircular, flabelliform, sometimes ungulate, projecting up to 9 cm, 20 cm wide and 40 mm thick at base. Pileal surface cream to white when fresh, turning to pale yellowish-brown, azonate or fairly zonate, glabrous to slightly velutinate, sometimes with irregular warts near base; margin obtuse. Pore surface cream to white when fresh, turning to yellowish brown to grayish brown when dry; pores round to near round, 1–2 per mm; dissepiments thick, entire. Sterile margin distinct, cream, up to 5 mm wide. Context white to cream, corky, zonate, up to 30 mm thick. Tubes pale cream buff to grayish-brown, leathery when fresh, corky, up to 10 mm long. Hyphal system trimitic; generative hyphae bearing clamp connections; skeletal and binding hyphae IKI–, CB–; tissues unchanged in KOH. Generative hyphae infrequent, hyaline, thin-walled, moderately branched, 2–3.8 µm in diam; skeletal hyphae dominant, hyaline, mostly thick-walled with a narrow lumen, occasionally with a wide lumen and usually collapsed when dry, occasionally branched, interwoven,3.2–6 µm in diam; binding hyphae hyaline, thick-walled to almost solid, frequently branched, flexuous, interwoven, 1.8–3.5 µm in diam. Generative hyphae infrequent, hyaline, thin-walled, moderately branched, 1.8–3 µm in diam; skeletal hyphae dominant, hyaline, mostly thick-walled with a narrow lumen, occasionally branched, straight, strongly interwoven, 2.5–4 µm in diam; binding hyphae hyaline, thick-walled to almost solid, frequently branched, flexuous, interwoven, 1.4–2.5 µm in diam. Cystidia and cystidioles absent. Basidia clavate, with four sterigmata and a basal clamp connection, 20–35 × 5–7 µm; basidioles in shape similar to basidia, but slightly smaller. Basidiospores cylindrical, hyaline, thin-walled, smooth, IKI–, CB–, (5.9 –)6–9(– 9.2) × (2.7–)3–4(– 4.3) µm, L = 7.63 µm, W = 3.39 µm, Q = 2.13–2.4 (n = 120/4).
Index Fungorum Number: IF203430
Notes: Trametes suaveolens is characterized by its white basidiocarps with strong anise odor, and usually discovered on wood of Populus or Salix.
