Exsudoporus frostii (Frost’s Bolete)

August. I saw Frost’s Bolete (Exsudoporus frostii; formerly Boletus frostii) for the first time on another trail in the park.

They were easily visible from the trail. Two ‘shiny’ red caps. The caps of young Frost’s boletes are sticky.

When I turned one over, I could see the red reticulate stem and the red pore surface. (The fluid isn’t unusual in young specimens; older specimens usually have dry pore surfaces.) It didn’t take long to identify this species.

I’ve since found it in several locations near the trail north, but not south, of the Fishing Area.

This beautiful specimen was growing between the trail and the reservoir shore.

Another older specimen, with a still somewhat shiny cap, was growing beside the trail.

The reticulation on the stem is much more pronounced, but less pigmented, in specimens as they age. The pore surface becomes brownish in older specimens although they still develop the deep blue/black color that results from bruising, when a colorless compound called boletol is exposed to air and oxidized to a blue color.

I’ve mentioned, on occasion, that I often sit or lie on the trail to take photographs. I was lying just past a slight bend in the trail when I took this photo. A tree in the bend hid me from other walkers on the trail. I became aware of a walker cautiously approaching, just out of eyesight. I realized that they could only see my legs and feet, and were probably wondering if they were encountering a body on the trail. I sat up and let them know I was a living creature. We laughed. This isn’t the first time other walkers have wondered if I was OK, but this was the funniest occurrence, depending on how you look at it.

Exsudoporus frostii had been found widely in eastern North America, Mexico, and Costa Rica.

Summer On A Fort Yargo State Park Trail: Section B To The Dam, July 8th (Part 2)

July 8th. (Continued from…). When I visited Fort Yargo State Park in mid-February, there were few signs of Spring. The only wildflower plants that were obvious were the leaves of Cranefly Orchids (Tipularia discolor) that I found in many places.

The route… I’ve described it here, here, here, and here This walk doesn’t have the variety of wildflowers as my other walk from the Group A Shelter to the Old Fort but it does have some gems. One of the Smallflower Pawpaw (Asimina parviflora) had developed fruit that, unfortunately, it had lost; the Pink Lady’s Slipper (Cypripedium acaule) Orchids had bloomed, and some Green Adder’s-mouth (Malaxis unifolia) Orchids had bloomed and two were setting seeds. The occurrence of slime mold fruiting bodies added a new focus of interest for this walk.

Before I started back along the return trail, I wandered around the area at the west end of the dam.

A Winged Sumac (Rhus copallinum) was beginning to bloom. I didn’t know it was a Winged Sumac at the time. I’ve always been confused by sumacs but, it turns out, this one gives itself away. It has…

narrow wings - ‘strips’ of leaf-like tissue – along the stalk between the leaflets.

The Bigroot Morning Glory (Ipomoea pandurata) vine was still blooming in the shade at the edge of the woods.

My next stop was the Hairy Angelica (Angelica venenosa). Seed capsules were starting to develop but a little surprise was waiting for me, literally. A…

Swift Crab Spider (Mecaphesa celer) was hunting on the top of the flower head. Many adult Swift Crab spiders are brightly colored but immature spiders are almost colorless. This spider was still mostly colorless.

I didn’t see this spider at first; it was perfectly camouflaged for the location it had chosen to hunt. Interestingly, among the many genera in the Crab Spider family Thomisidae, there are three genera – Misumena, Misumenoides, and Mecaphesa – that we find hunting on flowers. Spiders in these genera may be differentiated by the arrangement of the eyes; mecaphesas are also hairy.

My favorite tree was bathed in sunlight.

A couple of bright red mushroom caught my attention. They looked like they had been coated in red varnish. I guessed they were boletes – mushrooms that have pores instead of gills. There were several in the area, so I turned one over to take a closer look. Its …

pore surface was bright red and the stem had coarse reticulations. This was a very striking mushroom and it was relatively easy to identify as Frost’s Bolete (Boletus frostii).

The seed capsules were still developing on the New Jersey Tea (Ceanothus americanus).

The Oak Apple Gall had a tiny hole in it.

The Green Arrow Arum (Peltandra virginica) fruit were still healthy.

A log lying across a small gully at the lake’s edge was covered with mushrooms; their caps were about an inch in diameter. These fit the description of Fuzzy Foot (Xeromphalina campanella) mushrooms but I couldn’t get close to them.

Bicolor Lezpedeza (Lespedeza bicolor) bushes were still blooming. These bushes grow in an area that gets sun until early afternoon.

I found more ‘Honeycomb’ Coral Slime (Ceratiomyxa fruticulosa var. porioides) fruiting bodies on an old rotting log by the trail on the north section of the trail.

The seed capsules were still developing on the Perfoliate Bellwort (Uvularia perfoliata) plant.

A little way off the trail, I found a…

Dog Vomit (Fuligo septica) slime mold fruiting body that was a pale green.

Another lone Hairy Elephantsfoot (Elephantopus tomentosus) was blooming by the trail.

I found this cluster of pretty mushrooms growing at the base of a hardwood tree. I didn’t want to disturb this cluster so I turned over a…

smaller mushroom. The cap was convex when the mushroom was young but later inverted into a vase shape; the gills started to run down the stem and there was some evidence of cross gills. At this time, I haven’t been able to identify it.
