Termitomyces cylindricus
Termitomyces cylindricus S.C. He
Index fungorum number: 104821.
Pileus 5-7 cm diam., conic to convex then convexo-applanate to plane when mature, with an obtusely rounded perforatorium; surface white to cream, and yellow-brown at the center and paler toward margin, smooth and glabrous, margin straight, often radially splitting when mature. Lamellae free, white to cream and becoming pinkish when mature, 0.4 cm wide, crowded with lamellulae. Stipe 5-8.7 cm long, 0.7-1 cm wide, central, cylindrical to subcylindrical, surface white, smooth or longitudinally striate, solid fibrous. Annulus absent. Pseudorhiza 3-7 cm long, 0.3-0.5 cm thick, cylindrical to subcylindrical, surface white, smooth or longitudinally striate, solid. Spore deposit white. Basidiospores 5.5-10 x 4-7 μm, ovoid to ellipsoid; smooth and thin-walled, inamyloid. Basidia 7.5-22.5 x 5-8 μm, clavate, bearing four sterigmata, inamyloid. Hymenophoral trama regular, 55-70 μm wide, inamyloid. Cheilocystidia crowded, 20-46.3 x 13-30 μm, clavate to pyriform, smooth and thin-walled, inamyloid. Pleurocystidia 20-47.5 x 10-28 μm, similar to cheilocystidia Pileipellis a repent epicutis of narrow, radial hyphae, 1.5-2.5 μm diam.

Fig 1. Phylogenetic tree based on ITS1-5.8S-ITS2 of Termitomyces sequences in this study and from GenBank (blue letter) using the Maximum parsimony method. Agaricus abruptibulbus is used as an outgroup. Numbers at the node are bootstrap scores of 1000 replicates.

Fresh basidiocarps and microscopic features of Termitomyces cylindricus (A-F); arrowhead pointing at basidium (C); basidiospore (D); arrowhead pointing at cystidia (E, F), Termitomyces clypeatus (G-J); cystidium (H, I); basidiospores (J), Termitomyces fuliginosus (K-P); arrowhead pointing at cystidium (N, P); basidiospore (O). Scale bar: fresh basidiocarps = 1 cm; microscopic features = 10 μm.
