Observation 25539: Armillaria (Fr.) Staude

When: 2009-09-21

Collection location: Woodbury, Connecticut, USA [Click for map]

Who: Jeff Sherman (jeffs)

No specimen available

I’m a novice. On a walk I came across these on the roadside, mostly clustered around birch tree stumps.

They were clustered on the stumps of birch trees that had been cut in the past few years. The stem is fibrous and tough, the cap has tiny hair-like dots on it.

Looks like plate 182 in Gary Lincoff’s book.

Discussion is good.

You aren’t being argumentative and I think one of the points of MO is to arrive at consensus through discussion. The “Honey Mushrooms” aren’t easy to separate but in CT what I find in the early Fall are Armellaria gallica(hardwoods) and A. ostoyae (conifers). A. mellea is usually an early to mid-summer species(but not always) and much yellower than the other two I mentioned. My guess at A. gallica was based on the color of the cap, the season (late summer) and the habitat (birch). I could be mistaken but I believe the mushroom pictured in the Audubon field guide is A. ostoyae despite the A. mellea label. Somewhere I have a photo correction sheet for the mislabeled pics in the Audubon guide and I take a look later and post it.

Not to be argumentative, but maybe not Armillaria gallica, for these reasons:

According to http://www.mushroomexpert.com/armillaria_gallica.html:

Armillaria gallica "…is more apt to grow alone or in loose groups than in densely packed clusters that cause the stem bases to be pointed. In fact, the stem base of Armillaria gallica is swollen, exhibiting a “bulbicitiness” (Volk, 2004, pers. com.) not found in most other honey mushrooms."

The mushrooms I found were in densely packed clusters, and the stem bases were pointed and showed no “bulbicitiness”.
