Observation 46640: Lachnellula arida (W. Phillips) Dennis
When: 2010-06-05
Herbarium specimen reported

Notes: Found under mixed conifer forest, one small twig. Too small, not collected.

7/23/2010 – adding some micro-details.

The first micro-shot is of asci at 1000x in Meltzer’s. The asci’s here are 8-spored, and no reaction to Meltzer’s. The spores are ellipsoid, smooth, lacking oil drops, roughly 7 × 3 um. The asci’s here are rather short, only 55-70 um long.

The second micro-shot is of back of the ascocarp at 400x in Meltzer’s. These are the “hairs”, the stiff black hyphae on the back and around the edges of the “cup”. They are multi-septate, darkly pigmented and ornamented with warts.

Comparing this to notes in the “Champignons du Suisse”, tome 1, Breitenbach, it matches well with the description of Lachnellula arida there.

I wanted to check this out under the scope, since id’s of these tiny hairy cups seem to always be put to question. This one matches what was expected, given the experience of the Spring Fungi of the Sierras course over the years.
