Observation 161832: Fungi Bartl.
When: 2014-03-20
No herbarium specimen

Notes: At about 6500’ in ponderosa pine/gambal oak habitat. Growing on the inside surface of the bark of ponderosa pine. Almost every piece of bark on the ground under this dead standing ponderosa pine was covered in these. Very fibrous. Lichen? No rain since 3/2/14.

Recognized by sight: Multiple fibrous strands of what looks to be fungi. You say it was “Growing on the inside surface of the bark of ponderosa pine.” Lichen would be growing on the outside of the bark layer, not the inside. This is likely a fungi growing on the cambium layer, just under the bark.

Within a year of tree death,

something has eaten the cambium layer. It is the first thing colonized after death of a tree. Because it typically has sugar remnants still present, many fungi grow rapidly and readily on it. The bark may not fall off for several years. The fact that you found similar fungus growing on the bark-less area of a nearby dead Ponderosa pine, supports this premise.

Keep visiting the tree. It will likely produce a flush of mushrooms in the future, probably shortly after a rainfall.

I think you’re right—this is a fungus, probably a decay fungus like a white rot. It seems too homogeneous to be a lichen. Daniel, these were growing on the inner side of pieces of bark that were lying face up on the ground. At first I thought they had established themselves after the bark had fallen off the dead tree. Now I think they are, at least in part, what caused the bark to fall off the tree. Yesterday I found remnants of what look to be the same thing on the bark free surface of another dead standing ponderosa pine.

I thought it might be a filamentous lichen but so far can’t find anything similar.

perhaps mycelium?
