intro | The following description is based on Miller (1992). The information here has been based on the protolog of Amanita carneiphylla. |
cap | The fruit bodies of this species occur deeply inserted in sandy soil, usually with only the cap and uppermost stem exposed. The cap of Amanita carneiphylla is 50 - 75 mm wide, broadly convex, dry, dull white, with a nonstriate and appendiculate margin. The cap is sand-covered with low, soft, white volval warts over the center becoming less frequent or absent of the margin. The flesh is firm and white tinted pink, especially in age. |
gills | The gills are subdistant, broad, adnate, very light pink at first, gradually becoming pink. The short gills are of diverse lengths, approximately one for each normal gill. |
stem |
The stem is 135 - 150 × 15 - 20 mm, tapering, dull white, with an extensively rooting base, 60 - 90 × 25 - 35 mm. The ring is white, membranous, apical, striate on the upper surface, skirt-like. The volva is present as soft, white warts over the base of the stem and above the rooting bulb. The flesh is firm and white tinted pink, especially in age. |
odor/taste | Odor is absent. |
spores | The spores measure 10 - 12 × 5 - 6 µm and are cylindric and amyloid. Clamps are present at bases of basidia but the frequency is unknown. |
discussion |
Originally described from Western Australia in association with Eucalyptus, Banksia, and Allocasuarina growing in sandy soil. At one site, Mediterranean pine (Pinus) was also found. In Amanita, elongate bulbs, narrow spores, and fruiting bodies deeply inserted in the soil are often associated with "leaky" ecosystems (Tulloss 2005). For Miller's description of the volva, Bas' keys direct us to stirps Chlorinosma. This stirps is divided between pallid Northern hemisphere temperate taxa and Southern hemisphere tropical taxa. Amanita carneiphylla has the lack of pigment of the Northern hemisphere taxa but the narrow spores present in A. lanosula Bas known from the Republic of Congo. The pink gills and pink tint of the flesh are unknown in stirps Chlorinosma. In addition, the volval warts are much too coherent and well-formed (see above photos) for that stirps. It seems appropriate not to attempt placement of A. carneiphylla in Bas' system until more is known about it.—R. E. Tulloss |

intro |
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. The following material is derived entirely from the protolog of the present taxon. from protolog: Basidiomes medium-sized to large. | ||||||||
pileus | from protolog: 50 - 75 mm wide, dull white, broadly convex, dry, sand-covered; content firm, white, with pink tint (especially in age); margin nonstriate, often appendiculate with plentiful soft white material; universal veil as low soft white warts over center becoming less frequent or absent over margin. | ||||||||
lamellae | from protolog: adnate, subdistant, very light pink at first gradually becoming pink (9A2-3), broad, often decorated with soft white material of partial veil (disappearing with age); lamellulae in one tier, "alternating." | ||||||||
stipe | from protolog: 135 - 150 × 15 - 20 mm, 25 - 35 mm wide at base, surface dull white; bulb sand-covered, tapering, rooting, 60 - 90 mm long; context as in pileus; partial veil white, persistent at apex of stipe, hanging skirt-like, with striations on upper surface; universal veil as soft white warts on stipe base above bulb. | ||||||||
odor/taste | from protolog: Odor not distinct. Taste not described. | ||||||||
pileipellis | [Note: Miller's description of the pileipellis as a pallisade was very probably based on remnants of the universal veil. We have transferred the protolog's "pileipellis" description to the "universal veil" data field below. This seems reasonable as a first approximation, but revision of this species is needed.–ed.] | ||||||||
pileus context | from protolog: hyaline in KOH, light ochraceous in Melzer’s solution; filamentous hyphae 9 - 16 µm wide, thin-walled; acrophysalides often in clusters, ovoid to irregularly shaped; clamps scattered. | ||||||||
lamella trama | from protolog: bilateral; filamentous hyphae 3 - 6 µm wide, thin-walled, hyaline, largely subparallel, multi-branched, some swollen. | ||||||||
subhymenium | from protolog: filamentous hyphae 3 - 6 µm wide, thin-walled, very light ochraceous in Melzer’s solution, hyaline in KOH. | ||||||||
basidia | from protolog: 45 - 62 × 9 - 11 µm, narrowly clavate, thin-walled, hyaline., 4-sterigmate, with sterigmata 4 - 5 µm long[; clamps probably present]. [Note: Bas (1969) noted that if clamps are reported from one or more other tissues in an Amanita basidiome, they will be found at the bases of basidia.–ed.] | ||||||||
universal veil | from protolog: [On pileus, upper layer?–ed.] filamentous hyphae 3 - 7 (- 9) µm wide, branching, sparse; inflated cells very numerous, globose to clavate to fusiform to pyriform, thin-walled, hyaline, 18 - 48 µm wide, hyaline; clamps observed. [On pileus, apparent lower layer—misdescribed as "pileipellis" in protolog.—ed.] up to 350 - 480 µm thick, "loose trichodermial palisade," light yellow-brown in KOH, reddish brown in Melzer’s solution; filamentous hyphae, tangled, thin-walled 7.5 - 15 µm wide, with some inflated intercalary segments; inflated cells scattered, fusiform to clavate, terminal. | ||||||||
stipe context | not described in protolog. | ||||||||
partial veil | not described in protolog. | ||||||||
lamella edge tissue | not described in protolog. | ||||||||
basidiospores | from protolog: [-/-/-] 10.0 - 12.0 × 5.0 - 6.0 μm, (Q = 2.0 - 2.4; Q' = 2.17), thin-walled, amyloid, cylindric; apiculus proportionately? small; contents as "large oil globules"; color in deposit not recorded. | ||||||||
ecology | from protolog: Several to gregarious, "usually buried almost to the pileus in sandy soil." Under open stands of Eucalyptus marginata, Banksia menziesii, Allocasuarina fraseriana, and, in one area, [exotic] Pinus pinaster. | ||||||||

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.
