what do you mean A. solidipes (=A. ostoyae)?

are you suggesting these are synonyms?

Armillaria gallica (at the state of current knowledge seems to suggest)

Similar collections from California have been named A. gallica — note the texture on the cap and the evanescent, or rather broken partial veil remnants, compared to the solid membranous one of A. mellea. My main source for local info was the Mykoblitz at Point Reyes, which produced quite a few fruitbodies from a good variety of hosts. Supposedly, we got A. mellea s.s. (but Tom Bruns still had a few “if & but” comments on that “s.s.”) and A. gallica. No A. ostoyae had been seen. Of course Mr. Volk is the expert in that area, I only report the findings that have guided me so far with the Western species. Here is my interpretation of A. gallica, which typically fruits gregarious to limitedly caespitose, but not truly hugely clustered like A. mellea.

I have examined a few collections in search of A. sinapina, but the effort has not produced desired results yet.

Bigleaf maple or Red alder

Acer macrophylla or Alnus rubra. It was near the base of a Red alder, but that doesn’t mean it was growing from that tree, at least in this area. Everything gets clustered in this area.

not A. mellea

Hi Dan. we don’t have any records of A. mellea from Oregon, and this doesn’t look like it anyway (A. mellea is yellower and has pointed clusteredbases). Do you know what the host was? It could be A. gallica, but more likley A. sinapina. but probably not A. solidipes (=A. ostoyae)
