| intro |
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.
All information on this page is drawn from (Bas 1969).
Bas (1969): Basidiomes small, slender. |
| pileus |
Bas (1969): 25 - 45 mm wide, white, convex to plano-convex, dry; context white, unchanging, firm; margin non-sulcate; universal veil as small floccose patches and flecks uniformly distributed (per figure), white, minutely pulverulent-squamulose. |
| lamellae |
Bas (1969): free, crowded, white, 4 - 6 mm wide; lamellulae not described. |
| stipe |
Bas (1969): 70 - 100 × 6 mm, white, floccose-scabrous; context solid, white, unchanging, firm; bulb subventricose-fusiform, short-rooting, 8 - 10 mm wide; exannulate; universal veil not recorded separately from stipe decoration. |
| odor/taste |
not recorded. |
macrochemical
tests |
none recorded. |

Bas (1969): BOLIVIA:
DPTO. PANDO—Cobija [ca. 11°01'15" S/ 68°45'48" W, ca. 217 m], 1.ii.1948 E. J. H. Corner Bol. 9 (L). |
| discussion |
Bas (1969): "The collection studied consists of two dried, longitudinal slices of a stem and one very thin, radial slice of a cap accompanied by field-notes and a rough pencil-drawing. The tissues are difficult to study. For these reasons the collection is unsuitable for a type.
"Although the collection studied is very poor, sufficient data are known to be sure that it represents a species closely related to A. lilloi or perhaps even a form of that species. For the moment it seems expedient to keep this fungus apart under a provisional name because of the following facts: (i) The macroscopical aspect of the covering of the cap as noted in the field by Corner (minutely pulverulent-squamulose with small, floccose patches) is rather different from that in A. lilloi (with distinct, about 3-5 mm high, floccose warts). (ii) The stem of A. boliviana is exannulate; A. lilloi has a very distinct ring. (iii) The spores of A. boliviana are slightly larger than those of A. lilloi, viz. (7.5-) 8 - 9.3 × 6.5 - 7.5 (-8.5) μm against 7 - 8.5 × 6 - 7 (-7.5) μm."
The following figure provides the comparison of current sporographs for the two taxa named by Bas, above:
The sample of spores from material determined as A. lilloi has advance in the forty years since Bas' publication; however, no new information on A. boliviana has become known to us. There appears to be less difference in size and shape between the spores of the two species than was evident to Bas in 1969. |
