MycoBank: 811958 Basionym: Psathyrella secotioides G. Moreno, Heykoop, Esqueda & Olariaga 2015 l. c. Originaldiagnose: |
| "Basidiomata gregarious to caespitose (three basidiomata with united stipe base). Pileus 6-10 x 3-5 mm when dried, pale straw-yellow to very pale chre, conical to narrowly paraboloid, with obtuse apex, surface covered with a felty veil (under binocular microscope). Margin involute to straight, in young fruitbodies tightly united to the stipe, later slightly free. Lamellae ascending, tight, 1-1.5 mm broad, violaceous black, slightly anastomosed and sometimes aborted. Lamella edge paler. Stipe 20-30 x 0.5-1 mm, cylindrical, slightly broader at the base, fistulose, fragile, concolorous with the pileus, reddish brown when dried. Taste and odour not recorded. Pileipellis hymeniform consisting of clavate cells of 35-57 x 25-30 µm. Subcutis consisting of cylindrical interwoven hyphae, 5-20 µm broad, hyaline to pale yellow, 5-9 µm in diam. Basidia 4-spored, clavate, 22 x 12 µm, sterigmata up to 3 µm in length, difficult to observe since the material is very collapsed. Spores variable in shape but mainly broadly ellipsoid, 9.5-10.63-12.0 x 6.0-7.28-8.0 µm, Q=1.33-1.46-1.57 (1.69) (n=37), dark brown, smooth, without a germ pore, tick walled (up to 1 µm), some of them with a large gutttule. Pleuro- and cheilocystidia not observed, possibly absent, but their presence cannot be ruled out with certainly as the hymenium is highly collapsed. Clmap connections scarce and difficult to observe." |
