Voucher Collection of 10525 DLL was collected in a conifer forest on 13 November 2021 and basidiomata were scattered in redwood branchlet humus, in Cutten, Humboldt County, California. A complete description of the macroscopic features of fruiting bodies is available.
An ITS sequence was obtained by Sharon Squazzo who determined that this sequence was a 100% match to the sequences of DLL 10520, 10523 (Inat 171868045), 10533 (iNat193540206), MM10 and Buck McAoo (INat 30337093).
Description of the Microscopic Features of 10525dll
Basidiospores 5–6-angled, angles distinct, apex acute, obtuse, or flat, typically single droplet, in profile view subsodiametric to heterodiametric, on the average decidedly heterodiametric, 9–11.5 × 7.0–9.5 μm (xavg = 10.4 ± 0.56 × 8.2 ± 0.51 μm; Q = 1.1–1.4; Qavg =1.27 ± 0.08; n = 89).
Basidia clavate and tapered to a narrow base, a few with granules, separate easily, sides typically smooth, rarely with one or very rarely two indentations, 35.0–52.0 × 7.0–14.0 μm (xavg = 42.2 ± 3.34 × 11.7 ± 1.44 μm; Q = 2.9–5.3; Qavg =3.66 ± 0.53; n = 52); typically 4-sterigmate, rarely 2-sterigmate, sterigma length 1.00–6.39 μm (n = 50).
Gill Edge sterile in cross sections of the lamellae partially sterile but not on the entire lamellae; Hymenium 32.0–51.5 μm (n = 7). Subhymenium composed of tightly entangled hyphae, 8.5–15.0 μm wide (n = 8; Gill Trama 76.0–200.0 μm (n = 6) subbparallel and longitudinally entangled.
Lamellar Trama Hyphae in squash mounts of the gills, long to very long and narrow to broad, 35.0–153.0 × 4.5–20.0 μm (xavg = 81.3 ± 29.98 × 9.8 ± 3.55 μm; Q = 3.6–21.0; Qavg =9.1 ± 4.07; n = 47.
Cheilocystidia more abundant on one end of the lamellar edge, typically protruding 24.0–56.5 μm (n = 14) beyond the hymenium, solitary to scattered in the middle of the gill edge, at times very abundant, easily verifiable in mounts of a single lamellae if the cystidia protrude beyond the hymenium, colorless, thin-walled, aciculate to aculeate, then lanceolate, and most commonly rostrate ventricose with the rostrum narrow or cylindrical, short to very long and often capiculate or cylindrically lanceolate, 48.0–119.0 × 4.5–21.5 μm (xavg = 84.8 ± 16.07 × 12.2 ± 4.09 μm; Q = 2.6–19.5; Qavg =7.83 ± 3.37;n = 38).
Pleurocystidia similar to the cheilocystidia in shape and size47.67–118.73 × 4.43–21.55 μm (x = 84.81 ± 16.07 × 12.22 ± 4.09 μm ; E = 2.64–19.41; Q =7.83 ± 3.37;n = 38)..
Pileipellis in radial sections of the pileus up to 177–400 μm (n = 7). deep in the pileus center, elsewhere 65–128 μm deep; in the pileus center a trichodermium with the terminal 10 cells pigmented, erect and tightly entangled; these terminal cells are semi-erect to somewhat erect near the pileus center and entirely prostrate from the middle to the pileus margin; Pileocystidia cylindrical to narrowly clavate in shape, rarely clavate, 20.0–72.0 × 6. 0–11.5 μm (xavg = 47.1 ± 11.7 × 9.1 ± 1.43 μm; Q = 2.7–8.2; Qavg =5.3 ± 1.37; n = 28).
Subpellis not differentiated from the pileal trama.
Pileal Trama in radial sections of the pileus composed of a colorless layer from the pileipellis to the hymenium; Pileal Tramal Hyphae loosely to tightly entangled and subparallel, individual hyphae long to very long and narrow to broad, 14.0–73.0 × 2.0–13.0 μm (xavg = 36.3 ± 16.5 × 6.4 ± 3.00 μm; Q = 2.4–13.0; Qavg =6.42 ± 2.93; n = 25).
Stipitipellis 21.–58.0 μm (n = 7 )deep.. The stipe apex composed hymenial elements at the stop ½ inch; Caulocystidia similar in shape and form very smaller than the hymenial cystidia.
Stipe Tramal Hyphae composed of subparallel and longitudinally entangled hyphae in longitudinal sections of the stipe; individual hyphae were measured in squash mounts of the stipe trama, 17.5–171.0 × 8.0–26.5 μm (xavg = 92.2 ± 36.60 × 14.5 ± 4.01 μm; Q = 1.11–18.16; Qavg = 6.8 ± 3.36; n = 37).
Clamp connections absent in all tissues.
Pigmentation brown, intracellular and uniform in the pileipellis, colorless in the stipipellis; possibly colorless in the lamellar hyphae; some the stipe tramal hyphae with encrustations that are often difficult to determine. .
Oleiferous Hyphae abundant in the tramas of the pileus, stipe, and lamellae.
Lipoidal Hyphae absent.
Stipe Tramal Hyphae devoid of granules.
