Species list from Black Friday walk at Hartwood Acres on 11/27/2020

Another warm Black Friday saw a group of intrepid social distancing mushroom hunters meet at Hartwood acres to see what bargains we could find. With only a couple of days of frosts in the weeks before Black Friday there were high hopes for a wide range of species including some terrestrial gilled mushrooms. The group split with Cara Coulter and some hunters exploring the conifer section of Hartwood Acres to the north of the mansion and the main group visiting “Mushroom Valley” to the south. Meanwhile Judy Mackenroth went for a very socially distanced solo walk and contributed her list to this report.

In 2016 we found a rarely observed Clitocybe cokeri but hadn’t seen it since. This year I’m pleased to announce that we found it again. In the intervening time it has undergone a name change so is now know as Pseudoomphalina cokeri. On iNaturalist there is only one other site in the US where it has been identified we presume it is a more common but overlooked species.

There were quite a few new to the club species. One of them is a mushroom (or mold) that grows on another mushroom. The species is Epicoccum nigrum and it grows on old puffballs and was found and identified by Judy using club mycologists John Plischke III book. We found another mushroom mold  growing on the base of a Clavulina coralloides (White Coral Fungus) specimen, Helminthosphaeria clavariarum, it’s also in John’s book. We found a Multiclavula mucida (White Green-algae Coral) specimen in the mushroom valley. It’s an interesting species as it forms a symbiotic relationship with algae although it is not a lichen. Most fungi that form relationships with algae are Ascomycota but Multiclavula mucida is a Basidiomycete. Judy found a related species, Multiclavula corynoides, that is new to the club. It has a club like head rather than a straight club shape. A new to the club mycena species was identified by Cara Coulter, Mycena griseoviridis, along with one that is known. Mycena epipterygia (Yellow-stalked Fairy-helmet). The Mycena epipterygia is quite fun as it was very sticky. Both were in the conifer section of the woods. Cara also found Rhizomarasmius pyrrhocephalus, a marasmius like small mushroom with a dark colored tough and long stem, almost like a rhizomorph. Last of the new species that I am going to mention was Xylodon paradoxus a crust mushroom that at first glance you might think is Irpex lacteus, the Milk-white Toothed Polypore. On closer inspection you can see that it it is actually interesting shaped pores rather than tooth pores of Irpex lacteus, hence the common name Split Porecrust. Another way to differentiate them is that Irpex lacteus tends to have cap-like margins that extend beyond the substrate while Xylodon paradoxus does not.

If you were playing the fall bingo the walk would have been a great way to add to the board. We found 16 of the 25 species in one walk. Sadly you would not have been able to score a bingo.

And of course there was a selection of unidentified species on the table too.
