Remarks (internal):At the time the present author studied the type of this species, it proved to be difficult to form a good picture of Entoloma eximium, since the material available at that time was limited and in a bad state. Important characters, such as presence of cystidia and clamp-connections could not be verified. So most of the published description (Noordeloos, 1981) was based on the text published by Romagnesi (1944) in his original diagnosis. For obvious reasons the species was omitted in the first edition of the present work.
Recently, the species was recollected in France (Eyssartier et al. (1999) who published a very interesting contribution based on new collections, carefully compared with all available information from the herbarium of Romagnesi, including the type specimens. A complete new picture of this remarkable species was given. One of the striking features is the complete lack of cystidia, both cheilo- and pleurocystidia and the confirmation that clamp-connections are lacking. For this reason classification in subgenus Allocybe, close to E. excentricum, is out of the question. But, where to classify this species then? Eyssartier et al. (l.c.) suggest that this species belongs to sect. Entoloma on account of tricholomatoid habit, non hygrophanous, lustrous pileus, and intracellular pigment. The lack of clamp-connections and the heterodiametrical spores contradict such a placement, however.

Description:Entoloma eximium Romagn. ex Noordel., sp. nov. (fig. 314)
Rhodophyllus eximius Romagn. in Bull. Soc. Mycol. Fr. 60: 99. 1954 (nom. nud., diagnosi latina mancante).
Pileus up to 63 mm broad, initially conical, expanding to convex with pronounced or obtuse umbo, with inflexed or straight, often undulating margin, not hygrophanous, not translucently striate, white to creamy or ivory, dry, glabrous with a lustrous appearance, very finely radially fibrillose or veined. Lamellae moderately distant, adnate to (almost) free, (sub) ventricose, white then deep salmon pink with irregular, concolourous edge. Stipe 75-100 x 5.5-9.5 mm, cylindrical or slightly broadened towards base, straight or curved, white or whitish, fibrillose striate, pruinose at apex, solid then fistulose, very brittle. Context thin, brittle, white. Smell distinct, not farinaceous but slightly fruity (Romagnesi: reminiscent of coconut).
Spores 10-12 x 7.5-8.5 µm, Q = 1.2-1.5, Qav = 1.3, heterodiametrical, 5-6 angled in side view. Basidia 30-50 x 10-14 µm, 4-spored, clampless. Lamella edge fertile. Cystidia absent. Pileipellis a cutis of narrow, cylindrical hyphae, 2-7 µm wide, and subpellis made up of slightly inflated hyphae, up to 100 x 30 (-40) µm. Pileitrama made up of relatively long elements. Pigment hardly present, probably intracellular. Hymenophoral and pileitrama made up of relatively long, 10-20 µm wide elements. Clamp-connections absent.
Habitat and distribution: in deciduous forest, often in association with Carpinus betulus. So far known from a few localities in France.
