[ Section Vaginatae page. ] [ Amanita Studies home. ] [ Keys & Checklist/Picturebooks ] Amanita ochraceopallida Contu"Contu's Pallid Ringless Amanita" Technical description (t.b.d.) BRIEF DESCRIPTION: The following description is based on the original description by Contu (1998). The cap of A. ochraceopallida is 20 - 100 mm wide, uniformly very pallid with ochraceous brown tint, campanulate-convex, eventually broadly convex, with or without an obtuse umbo, slightly viscid when moist, with a striate margin. The volva is present as white, unchanging warts of varying small sizes. The gills are free, moderately crowded, ventricose, white, with a flesh pink or pale cream tint, with an uneven, slightly flocculose and concolorous edge. The stem is 70 - 130 × 8 - 15 mm, cylindric, narrowing upward, white, with a frost-like concolorous covering which is rarely broken up into whitish concentric bands. No ring is present. The volva is membranous, saccate, persistent, white on the outside, tending to be grayish with yellow-orange spotting. The flesh is white and unchanging. The odor and taste are weak. Spores measured by RET are (9.0-) 9.1 - 12.8 (-16.5) × (8.0-) 8.3 - 11.4 (-13.5) µm and are subglobose to broadly ellipsoid and inamyloid. Clamps are absent at bases of basidia. This species was originally described from Sardinia (Italy) in a mountain habitat under plantations of fir (Abies cephalonica). This species is rare and localized on Sardinia. In the notes on two of the paratypes, Dr. Contu states that "this is the sole Amanita species occurring in Abies plantations in Sardinia." Dr. Contu was kind enough to send RET portions of two of the paratypes of this species from which the spore measurements above were taken. Since the spore measurements provided in the original description are exactly the same as those provided here with the extremes of length and width eliminated, it may be that the type materials' spores were not measured. Revision of the type would be useful. Based on the material RET has examined, A. ochraceopallida is closest to the species group listed on the A. crocea (Quél. in Bourd.)
