After a month of dry weather around Pittsburgh it was a pleasant surprise to arrive at Linn Run State Park and find plenty of gilled mushrooms growing in the parking lot. It just got better as we headed up the hill finding a wide variety of species. The table at the end of the walk was a joy to see with so many different mushrooms, of all sorts of colors, from tinny to large.

One the smaller side there were some pretty orange Entoloma quadratum and Cantharellus minor around the parking lot.

We found at least 8 species of Amanita. The most beautiful mushroom of the day went to a Amanita jacksonii specimen. Using a chemical field test we determined that the white destroying angle did not stain yellow with KOH leading to the identification of Amanita magnivelaris.

We found a few edible species including quite a few Cantharellus appalachiensis, one of which is pictured in the slide show that had a very interesting false gill presentation.There was also a chicken of the woods (Laetiporus sulphureus), a lone gem studded puffball (Lycoperdon perlatum) and some black staining polypore (Meripilus sumstinei).

On the fun side there were a couple of insect attacking species with a Cordyceps militaris (Trooping Cordyceps) and a crane fly that had been infected with the white Erynia sepulchralis.

I find that the mushrooms walks and mycology very rewarding and sometime useful in unexpected ways. Old specimens of Trichaptum biforme (Violet Toothed-Polypore) can be infected with another species, Phaeocalicium polyporaeum, that fruits in tiny black pins on the top surface of the mushroom. I’ve been looking for it for some time. A specimen was found on the walk but when I looked I could not see the pins with out a magnifying glass. I now know that I need to visit the optician and update my prescription. How useful was that!

Thanks to the 20 or so people who joined the walk on this fine day and found so many interesting mushrooms.
