Identificaciones de pamjanszen

Sporocarps: crowded in 2 small groups on decorticated conifer wood in melting snow; globose to subglobose, 0.8-1.0 mm tall by 0.8-1.5 mm diam.; black with silvery-blue iridescent reflections. Peridium: thin, delicate, silvery-grey, slighty iridescent, hyaline by transmitted light. Columella: none. Capillitium: sparse, branching and forming a loose net with thin, flexuose tips; threads dark brown and paler at extremeties, with many dark, rounded or elongated nodules. Spores: (11.8)12.3-13.7(16.7) µm, dark brown with a prominent bulging paler side, spinulose.

Sporocarps: sessile or short-stalked, 0.7-1.7 mm total height, brightly coloured. Stalk: 0-0.6 mm (if present <1/2 total height), black, widened at the base. Sporothecae: globose to slightly oblate, 0.6-1.1 mm diam. Peridium: membranous, wrinkled, persistent, iridescent, ranging from purple-violet to turquoise blue, dehiscing irregularly; hyaline by transmitted light. Columella: reaching 1/2 or less height of sporotheca. Capillitium: radiating from the top of the columella, dark brown becoming abruptly colourless at the periphery; threads branched and anastomosed, forking into short free ends at tips, with dark brown nodular and axillary expansions. Spores: globose to subglobose, 10.4-11.8 µm, dark brown, paler and bulging on one side, densely and evenly spinulose. Habitat: on bark of Tsuga mertensiana near melting snow.

Growing on alder bark and wood. Sporocarps mostly indistinct and melded together, individuals visible only in one section. Hypothallus brown, runs underneath sporocarp mass, curls up at one point. Shows “pockets” where individual sporocarps would have been. Capillitium bright yellow with clear spiralling pattern, tapers off abruptly. Couldn’t see any spines on elaters. Spores with rough, wide reticulate pattern and subglobose shape.

@tyson_ehlers @ryan_durand @pamjanszen Feeling confident on genus, kinda winging it with species. O. persimile seemed like the best match, but I struggled to find any evidence that could really convince me.

Sporophores: sporocarps and plasmodiocarps, subglobose, 0.8-2.0 mm diam. x 0.7-0.8 mm tall, crowded on branch of subalpine shrub. Hypothallus: extensive, coated in lime granules, forming a mound under the sporophore. Peridium: double; outer lime crust eggshell smooth to granular, easily separating from, membranous inner layer that appears blackish, iridescent, or greyish white when coated in fine lime, clear to yellowish-orange by TL; granules 2.4-4.5 um. Columella: absent or formed by a convex thickening of the basal plate, ochraceous to light orange, elongated. Capillitium: radiating from columella and connecting to peridium, simply branched, threads 0.9-2.8 um, straight or slightly flexuous, pale brown, becoming thinner and hyaline toward ends, ornamented with warts, nodules, dark brown fusiform swellings and occasional darker brown membranous expansions at axillary nodes. Spores: (9.1)9.5-12.5(15.0) µm, dark brown, spinose (baculate?), spines/baculae sometimes converging in short rows.
