cap |
The fruiting bodies of A. liquii are large. Its cap is 100 - 140 mm wide, at first nearly hemispherical, then convex to plano-convex; its center is often slightly umbonate. It is sepia to blackish, becoming blackish brown to dark brown towards the margin; and it lacks any yellow tint at all stages of development. Its margin is tuberculate-striate (extending 15% to 25% of the cap radius), and non-appendiculate. The volval remnants on the cap are dark grey to sepia, sometimes grey, felty to irregularly formed to verrucose, 2 - 10 mm wide and 1 - 3 mm high. The context is white. |
gills |
The gills of this species are free, crowded, white to cream-colored when young, greyish when mature, with blackish to dark brown free edges; the short gills are truncate to subtruncate. |
stem |
The exannulate stem of A. liquii is 130 - 170 × 15 - 30 mm, subcylindric or slightly tapering upward, whitish to brownish, and densely covered with dark grey to blackish squamules often in belts; its context white but at very base often greyish, sometimes brownish to light rusty brown, and stuffed to hollow. The stipe has no basal bulb. Volval remnants on the stipe are verrucose to subconical to granular, grey to dark grey to brownish in parts most distant from the stem, becoming paler towards bases of the remnants; the remnants are arranged in incomplete belts at the stipe base. |
odor/taste |
The odor is indistinct. |
spores |
Spores measure (11.0-) 11.5 - 15.0 (-24.0) × (9.5-) 11.0 - 14.5 (-20.0) µm and are globose to subglobose, and inamyloid. Clamps are not present on the bases of basidia. |

The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain.

discussion | from protolog: "... Several collections cited above were regarded as A. ceciliae by Yang (1997). Amanita liquii is similar to A. ceciliae (Berk. & Broome) Bas, A. beckeri Huijsman ex Huijsman, A. cinctipes Corner & Bas, and A. sororcula Tulloss, Ovrebo & Halling. Actually, several Chinese amanitas of this group have been determined as A. ceciliae, originally described from Europe (Teng 1936 and 1996 as Amanitopsis strangulata [Fr.] Roze; Mao 1990 as A. inaurata Secr. Ex Gillet; Yang 1997). However, the European A. ceciliae differs from A. liquii by its yellow-brown, reddish brown to gray-brown or olive-brown pileus covered with lighter colored (grayish to brownish) volval remnants, white lamellae with a white edge, much paler-colored squamules on the stipe and somewhat smaller basidiospores. The basidiospores of A. ceciliae are 10.4 - 14.1 × 9.7 - 14.0 µm per Breitenbach and Kränzlin (1995). Furthermore, the volval remnants at the base of the stipe of A. ceciliae often form a ring-zone above a strangulate region and a nearly cupulate structure at the very base of the stipe (Phillips 1990, Breitenbach and Kränzlin 1995). The vacuolar pigments in the cells of the sterile strip along the lamellar edge and volval remnants on the pileus of A. liquii are much darker than those of European A. ceciliae {[material examined]: FRANCE: JURA—ca. Noga, 2.x.1992 C. Bas 9341 (L)}. Amanita beckeri, originally described from Europe, differs from A. liquii in its differently colored pileus, lighter-colored volval remnants and smaller basidiospores (Huijsman 1962a, b, Tulloss 1994). The basidiospores of A. beckeri are (8.8-) 9.8 - 11.8 (-13.0) × (7.2-) 9.0 - 11.0 (-12.2) µm (Tulloss 1994). Amanita cinctipes, originally described from Southeast Asia, is distinguished from A. liquii by its slender fruit body lacking an umbo on the pileus, smaller basidia and smaller basidiospores (Corner and Bas 1962). Basidia and the basidiospores of A. cinctipes are 40 - 50 × 15 - 15 µm and 8.2 - 11.1 × 7.8 - 10.1 µm respectively (Corner and Bas 1962). Amanita sororcula, originally described from Columbia, differs from A. liquii by its smaller and more slender fruit body with [proportionately] longer marginal striations on the pileus, volval remnants tending to darken considerably with age and smaller basidiospores (Tulloss et al 1992, Tulloss pers comm.). The basidiospores of A. sororcula are (8.8-) 9.7 - 12.8 (-16.8) × (8.0-) 8.8 - 12.0 (-15.5) µm (Tulloss et al 1992)." | ||||||||||||||||

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
