Collection location: Davis, California, USA [Click for map]
Spores with ~ 1 μm wide germ pore
Spore range = 12 – 15 × 7 – 9 μ
Average spore = 13.75 × 7.95 μ
Q range = 1.5 – 1.88
Average Q = 1.73
20 spores measured.
The cheilocsytidia, pileocystidia, caulocystidia were abundant, the pleurocystidia was rare & scattered, the basidia was 4-spored. All cystidia and basidia sometimes with brown contents observed in KOH and occasionally had clamps at the base, clamps were also observed on the gill & stem hyphae.
Cheilocystidia range (13 measured) = (19) 31 – 53 (58) x 9 – 17 μ
Average cheilocsytidia = 40.62 × 11.08 μ
Pleurocystidia measured = 39×19, 41×16, 48×19, 49×20, 53×18, 53×24 μ
Basidia measured = 30×9, 35×10 μ
Pileocystidia range (10 measured, one over 100 μ long) = (41) 57 – 71 (73) x 9 – 12 μ
Average pileocystidia = 63.75 × 10.1 μ
Caulocystidia range (20 measured) = (35) 36 – 68 (73) x 9 – 15 (17) μ
Average caulocsytidia = 50.1 × 12.15 μ
The taste and smell were farinaceous.

This collection sure did have an overabundance of pileocystidia, assuming this is not a variable characteristic it would be hard to miss.
Pileocystidia can be variable, occurring in some parts of the cap and not others. It would take careful examination of several collections to know for sure. Seems sketchy to claim that there is a whole different species out there….and the main difference is that it has pileocystidia. The overlapping pleurocystidia size isn’t very convincing either.
15. Pileus young with olivaceous tinge; pileocystidia lacking; spores up to 14.5
× 8.5 µm in size; pleurocystidia globose, 25–40 µm long . . . . . . . . . . A. smithii Watl. & Bigelow in Mycotaxon
17: 378. 1983; not yet found in the Netherlands. According to Enderle
(in Doc. mycol. 25(100): 147–150. 1995) occurring in southern Germany.
15. Pileus without olivaceous tinges; pileocystidia present; spores up to 13.5 × 7.5 µm in size; pleurocystidia clavate or utriform, 35–55(65) µm long . . . . . . . . . . . . . . . . . . 8. A. putaminum
Especially given that this is an European name…
Here is a tree which includes this collection. It is the same as specimens from New Zealand and from Michigan. The Michigan collections are labeled A. smithii – they may be misidentified, or the two species might be conspecific. If they are the same, the name A. putaminum takes precedence because it is older.
One was fried up with oil, salt, & pepper. It tasted better then expected and the farinaceous taste disappears with cooking, I did not get sick. It will be interesting to try these again with an actual recipe.
