Observation 75765: Mycena haematopus (Pers.) P. Kumm.

When: 2011-07-30

Collection location: Thoiry, France [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under spruce, fir, on the inside of rotting stump.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are fusoid, long and pointed. No pleurocystidia were obs. The gill trama here is dextrinoid.

The second micro-shot is of some spores from the gill at 1000x in Meltzer’s. The spores are ellipsoid, smooth, and amyloid. The apr. size is 9 × 5 um. It is hard to see the spores here from other random droplets from the gills, sorry, look for the ellipsoid things, that are slightly pointed (acute to the end).

Didn’t think anything about these when I found them. And not until later looking over the photos did I see the red-ish tones to the grey-brown, and the slightly hanging margin to the caps. So, I put a gill under the scope to get more data, the cystidia, spores, and the dextrinoid lamellae trama all agree with M. haematopus also. So, a little extra work, since this is the first time I saw this one in Europe.
