Observation 95723: Mycena sanguinolenta (Alb. & Schwein.) P. Kumm.

When: 2012-05-28

Collection location: Shenandoah National Park, Warren Co., Virginia, USA [Click for map]

Who: Martin Livezey (MLivezey)

No specimen available

Unusual to me as it seems too early and it is growing on the ground, although the ground could have been well rotted or hidden wood. On Appalachian Trail near mile marker 20 in Shenandoah National Park. Gills marginate.Some interesting chemistry is noted here:http://en.wikipedia.org/wiki/Mycena_haematopusDescription of M. sanguinolenta is consistent with observation but no conifers in sight.

I am sorry I did not collect this so that I could have a closer look.

is no problem with that species but I do not think it is M. sanguinolenta. It does not look like it macroscopically.

I like that

Douglas does not believe this is either of the species posted. That means this is undocumented or atypical. Did you see David put this on the front page of the BAM website? I’m famous dude!

Fantastic lead image Martin!

Too bad that one guy’s opinion is keeping it off your front page.

I’ve been here before myself, you reminded me of this one:


Which was also on oak leaves, no conifers around. No one commented from Europe on that one, so either there is a rare other species here, or a rare habitat for M. sanguinolenta.

I wonder did I dry and keep those… I might have.

HABITAT single or widely scattered to gregarious or in tufts “on leaf mold and needles in woods or at their edges”, (Arora), gregarious on leaf mold, moss beds, or needle carpets, spring and fall, (Smith), scattered or in small groups, more rarely subfasciculate [almost bundled], on “humus and vegetable debris among grass and moss, on fallen twigs and moss-covered trunks of deciduous trees, among fallen needles of coniferous trees” (Juniperus, Pinus), more rarely even on decayed Pinus cones, (Maas Geesteranus)

Almost more like the M. californica from out here under live oak… Did you check Smith’s Mycena book for other maybe marginate bleeding mycenas?

fun with fungus fotos

The range of appearance of M. haematopus on MO is quite large. M. haematopus var. marginata is also listed. I am sure Smith and others


have studied this, but I don’t see much in the lit. to distinguish the 3 possibilities on a microscopic level. I wonder if M. haematopus and M. sanguinolenta would benefit from a basic review at the microscopic level.., No sample taken for this ob.

Those are really nice photos!

According to some sources (if I correctly recall) the terrestrial version of the Bleeding Mycena is given either species or variety status.

Thanks David

I wish I could have a Mai Tai under there right now!
