Observation 113744: Laccaria ochropurpurea (Berk.) Peck
When: 2012-10-17
Who: DrB
Herbarium specimen reported

Notes: Purple gills, relatively small in chord (depth), attached to stipe, relatively sparse in interval, staggered in span with a periodic length variation of about (100%, 25%, 80%, 25%, 100%). No latex produced. Gills somewhat resemble those of some cortinarius in sparseness. No cortina remnants recognizable.

Cap is khaki to buff in color when dry becoming fawn brown when wet, dry, smooth, neither tacky or sticky when wet, about 2" in diameter. Margin is incurved, becoming somewhat wavy with age but still incurved. Cap is somewhat offset from center with respect to stipe.

Stipe solid, firm, ~2.5-3" tall, ~.5"-.8" thick, with a ~.5mm thick skin dark brown in section (only, a lighter color superficially) and uniformly lightly colored core of a light brown/slightly reddish color. Somewhat clubbed at base, thicker, “j” shaped. No signs of veil or volva. About halfway down becoming vertically finely lined brown on buff with short fibrous scattered tags, above halfway length to under cap more of a smoother gray.

Odor strong, resembling agaricus bisporus but more intense, not unpleasant.

Growing in patches on ground under mature deciduous hardwoods, principally hickory and white oak.

Spore print pending.

Odor of purple gilled laccaria?

Thank you for your id.

My references don’t mention an odor of laccaria, can you please comment? The odor is noticeably strong. Also, some reference pictures such as audubon plate 336 don’t bear a strong resemblance (though mo images appear generally consistent).

Best regards, DrB
