"Pileus primo subglobosus dein globoso-conicus, ad apicem depressus, primo 2.5-3.5 cm longus, post expansionem 3.0-4.5 cm latus, postremo per autolysem destructus, griseibrunneus, ad apicem atrogriseibrunneus et sic remanens usque ad nigrescionem admodum ante autolysem; pagina pilei haud plicato-striata, pro parte maxima laevis et glabra, aliquot fibrillis parvis brunneis dispersis et adpressis. Caro ad marginem tenuis et apicem versus incrassata, usque ad 2.0 mm crassa. Stipes cavus, longus et gracilis, in medio amplificatus, basim et apicem versus leviter contractus, basis in substrato peniter radicata, supra medium albus, infra medium laevis, sericeus, opacus vel notis coloratis exhibens. Zona parva annuliformi vel volvoformi prope medium stipitis est locus ubi margo pilei immaturi in paginem stipitis conjungitur. Caro aliquantum crassa, fibrosa etsi friabilis, 1.0-3.0 mm crassa. Lamellae lanceolatae 1.0-3.3 cm longae, 0.8-1.1 cm crassae, ab inition confertissimae et sic remanens dum per autolysem destructae, sordide albae dein alutaceae, postea brunneipurpureae, postremo atrobrunneae; autolysis completa. Sporae ellipsoideae, leviter complanatae, aspectu laterali latissimae, 7.5-9.0 x 4.5-5.4 µm, poro germinationis apicali 1.0-2.0 µm lato, in cumulo brunneiatrae, per microscopium ["microsporium"] fumosibrunneae, guttulatae, rasilitunicatae. Basidia trimorphica, tetraspora, basidia breviter clavata 13.5-17.5 µm longa, 8.0-8.5 µm crassa, basidia longe clavata 19.0-21.0 µm longa, 7.5-8.0 µm crassa, basidia longissima et clavata vel subululiformia 26.0-27.5 µm longa, 6.5-8.0 µm crassa. Cheilocystidia variabilissima, interdum globosa 14.0-36.0 µm lata, aliter ellipsoidea vel subcylindracea vel etiam subtibiiformia, 77.0-101.0 x 14.0-38.0 x 10.0-14.0 x 12.0-18.0 µm, hyalina, tenuitunicata, apicibus nunc obtusis nunc subcapitatis et aliquando irregulariter ramosis. Pleurocystidia ellipsoidea vel subcylindracea, 122.5-165.0 x 34.0-46.0 µm, longa, hyalina, tenuitunicata, interdum pedicello 2.0-8.0 µm. Pagina pilei ex hyphis cylindraceis radiatim dispositis. Velum universale ad basem stipitis et in pagina pilei ex frustillis squaminformibus quibus e multitudinibus coadunitis contentorum amorphorum luteibrunneorum hypharum gracilium cylindricarum facuntur; frustilla stipitis cum tomentoso laxo intexto hypharum gracilium tenuitunicatarum 1.0-2.5 µm diam commiscuntur; hyphae illae prominentiam annuliformem facunt. Hyphae tomenti illius contanta amorpha luteibrunnea aliquandr habent. Fibula in trama lamellorum adsunt. Holotypus FVDB 1745, terrestris vel sublignicola, in solo prope Salicem, solitarius vel in turmis parvis, in sylva Watermain dicta prope oppidum Redmond dictum, comitato King pagi Washingtonis 1 Novembris 1972 lectus, in herbario Universitatis Washingtonis (WTU) conservatus." |
