Observation 189134: Laccaria tortilis (Bolton) Cooke

When: 2014-11-20

Collection location: Juliana Trail, Longview, Gregg Co, Texas, USA [Click for map]

Who: L G Price (LG_Price)

No specimen available

Small group growing from forest floor next to trail. The forest is mixed pine and hardwoods. The closest mature trees were Loblolly and Shortleaf Pine.

I am not sure if this is a gilled mushroom.

Initially opens as a cup with “gills” or “ridges” on the outside. The color is a salmon color, lighter around the edge of the cup. The cup is about 3/4 inch (2 cm) in diameter. The cup is soft. The flesh is very thin and lighter like the edge of the cup.

Gills – I am not sure how to describe the gills. It’s as if they were primitive gills.

The stem is fairly soft, bends, fibrous, rough on the outside, darker reddish brown than cup. Stem is simple and rooted in soil. I could see white mycelium but there were numerous mushrooms in a small area ( 2 feet square). The stem is about 6 cm long.

The inside of the cup was dotted with darker tiny spots and maybe scales, very small.

Spore print is in progress.

My mistake, LG.

I did not notice the last 2 photos.

It seems probable that this fungus is Laccaria tortillis, or perhaps something similar to that species.

I have been collecting L. tortillis for several year at a local hospital, associated with mats of lungwort: a rather unusual host.

Well, you are right in that I did not take precise measurements. I did provide two photographs with the group image next to a piece of tape 2 inches long with inch and cm markings.

I also stated that the cup was about 1 cm across and the stipe about 6 cm long.

In the future it would be better for me to make more accurate measurements.

You are right!

The apparent scales on the cap and stipe are exactly that.

Laccaria has a long history of mycorrhizal relationships mostly with Pinus. It is an ancient genus. The ““gills” or “ridges”” seens to me to be a very accurate descriptions of the fungal hymenium.

One thing is missing from your descriptions, LG. Size. This would be an excellent time to add that information (hint, hint).

immature Laccaria?

It’s the right color.
