Observation 225609: Mycena (Pers.) Roussel

When: 2015-12-17

Collection location: Hinsley Park, Longview, Texas, USA [Click for map]

Who: L G Price (LG_Price)

Specimen available

Notes:
UPDATE: Going through the keys on MushroomExpert, this seems to be closest to Mycena epipterygia var. lignicola or Mycena epipterygia. However, I don’t think it is either one of these. (looking at the spores may help – but not tonight)

Habitat: wooded area, in the moss growing on the north side of a very large Loblolly Pine on the side of a tiny intermittent stream.

Photos – debris on the surfaces result due to the stickiness.

Spore Print – White

Spore Dimensions – TBD

Smell: didn’t notice any. Later crushed a cap. It had a distinctive odor, but just the odor of the woods – not an unusual odor, not spicey, radishy, or other.
Taste: did not

Cap: Thin, translucent, sticky. Olive-yellow color. Bell shape – see photos. 1.5 cm diameter.

Gills: olive yellow tone like stipe. See image. Attached to stalk but pulling free at maturity. Thin, sub-distant to close.

Stipe: 2 X width of cap. Olive-yellow on the middle and upper section, sticky, hollow. Rooted, relatively long root. Lower section of stipe is darker with a reddish tint. Stipe shows a bit of clear liquid when cut but no other liquid.

Microscopic Features -

Stipe section – a thin cross section was taken making a ring ( as the stipe was hollow). The ring was cut in half. The half was flattened and a thin cross section taken. I don’t think this is a good way. The resulting images show what appears to be long cysts that take the fushia stain. ( However, these may be nimatodes or something else.) see image

Spore images: TBD

Cap: Aquaduct section. See image of one cyst that pulled free. Notice think basidium appendages that hold the developing spores. All basisia appeared to have this stout structure. Also, large cysts were seen of clavate shape – 10 microns by 30-35 microns.
