Conocybe ochroalbida Hauskn

Diagnosis fuente: FUNGI NON DELINEATI - Pars II - Some rare Agaricales with brown or darker spores A. Hausknecht & I. Krisai-Greilhuber - Libreria Basso
Description:
Pileus: (7-) 9-25 (-35) mm broad, hemispherical, flat convex, rarely flat conical-campanulate, always broader than high, very young and fresh in the centre pale brown orange, golden blond, pale topaz, towards margin pale orange gray, alabaster, very soon pallescent, grayish beige to beige white, whitish to white when dry; hygrophanous, but never found striate. Surface smooth, sometimes slightly costate-striate towards margin, slightly greasy shining when humid [similar to Conocybe rickenii (J. Schiff.) Ktihner].
Lamellae: narrowly adnate, ventricose, slightly distant, very pale even when mature, near camel, with concolorous, smooth lamellar edge.
Stipe: 30-45 mm long, 1.5-2.5 mm thick, with small but distinct basal bulb, young hyaline white, later pale orange (ca. SAB3), near the base often more brownish orange, pruinose and longitudinally striate in whole length; macroscopically no hairs visible even in fresh condition,
Context: smell and taste weak, slightly similiar to cocoa like in some
to Psathyrella species.
Spores: 6.8-9.1 x 4.6-5.4 um, Q= 7,8 x 5.0 (type), in other collections also smaller, mostly 6.8-7.2 x 4.5-4.9 um, ovoid-ellipsoidal, smooth, never lentiform, with simple wall and small, distinct germ pore (ca. | pm), light yellow in water, yellowish brown with light reddish wall in KOHL, NH3 reaction: even after 12 hours negative.
Basidia: 4-(occasionally 2-)spored, 15-20 x 7-8.5 um.
Clamp connections: frequent.
Cheilocystidia: lecythiform, 18-26 x 7-12 tum, with 3.5-5 um large capitulum, short to long neck and lageniform to nearly spherical body, partly with two capitula.
Stipe covering: consisting of parallel hyphac, predominately covered with lecythiform cystidia similar to cheilocystidia, but in between also dispersed or aggregated cylindrical-clavate to ventricose elements, frequently arranged chainlike, The lecythiform cystidia often have a long neck similar to that of Conocybe subpallida Enderle.
Epicutis of pileus: a hymeniderm consisting of 18-28 um broad, sphericopedunculate cells, between them occasionally to frequently lecythiform cystidia similar to cheilocystidia.
Habitat and distribution: up to now only known from dry meadows and dry grassland on sandy soil, in steppelike vegetation, and on south-exposed, steep slopes over loess.
