Original diagnosis:
"Pileus 22-34 mm., e convexo expansus vel leviter depressus, interdum ad marigem undulato-lobatus, umbrinus, siccitate pallide sordide umbrinus dein nunc sordide luteolus nunc ochraceus ad discum obscuriore ochraceo-brunneus vel fulvotinctus, jove pluvio exstriatus sed juxta marginem radialiter obscuriore lineatus, e velo albido vel palllide sordide luteolo-brunneo squamulis adpressis interdum leviter recurvatis circa marginem ad partem internam magis dispersis obtectus. Lamellae adnate interdum dente decurrentes, +/- ventricosae, pallide argillaceo-umbrinae dein cacainae vel violaceo-umbrinmae (colore lamellarum Agarici campestris), subconfertae L 24-32 l 3, ad aciem albo-floccosae. Stipes 25-45/2 ½- 5 mm., aequalis vel sursum attenuatus, ad basim interdum incrassatus, albus dein sursum sordide brunneolus vel pallide cacainus, ad apicem albo-pruinosus, infra e velo albo vel albido squamulis elongatis fibrilloso-floccosis fere totus obtectus, cavus, ad basim albo-tomentosus. Caro pilei concolorata, stipitis in corticem alba intus ochracea vel pallide umbrina. Sporae ellipsoideo-phaseoliformes, 7-8½/4-5 µ. Basidia 4-sporigera, 28-30/9-10 µ. Cystidia aciei lamellarum (1) vesiculosa, clavata vel pyriformia, 20-39/10-20 µ, (2) lageniformia cervice aliquantum longa et ad apicem obtusa, tenuitunicata, 30-50/10-14 µ ad apicem 4-8 µ lata. Cystidia faciei lamellarum lageniformia ad apicem obtusa 40-60/1-15 µ, ad apicem (4)6-8 µ, aliquantum tenuitunicata. Cuticula pilei cellularis cellulae 24-48 µ latae; cellulae hypharum veli subcylindricae, hyalinae, 4-8(12) µ latae; cellulae fibulatae non visi. Ad terram sub Quercubus, Surlingham Wood, Surlingham, Norfolk, 18 Oct. 1957 (typus in Herb. Kew.). A P. spintrigeroides proxime accedit, sed a cystidiis facieri lamellarum obtusis, habitatione et coloribus differt. P. xanthocystis et P. jerdonii a sporis majoribus differunt."
