Harbins Park: Day of the Fungi (Part 2)

After I turned onto the emergency exit (C ) and walked down to the hiking trail (D) and over to the equestrian trail (F), I started to see lichens – a lot of lichens. There are an enormous number of lichens and I’m not an expert at identifying them. Any corrections to my guess are more than welcome.

I started to see these lichens after I turned onto the emergency exit trail. They became thicker and more common as I walked down towards the river. The guide to common lichens on the Georgia Piedmont suggests that this is probably the Dixie Reindeer lichen, Cladina (Cladonia) subtenuis.

A close up.

I found a few small patches of the Crowned Pixie-cup lichen (Cladonia carneola) on rotting logs.

A closer view.

This appears to be the Peg lichen (Cladonia sobolescens). I found these on a mound of soil covered with moss in the same area where I found the Crowned Pixie-cup lichens. This lichen resembles the British Soldier lichen (Cladonia cristatella) which have red fruiting bodies and which I'd seen in January.

Areas around the overlook over the Alcovy River were covered with carpets of the Dixie Reindeer lichen.

I think these are the Perforated Ruffle lichen (Parmotrema perforatum). I saw these on the trunk of a tree along the Miller Lake Trail in Mulberry Creek Park and they are on trees in our field where they are blue-green with brown cups. I was struck by the fact that these were greenish with green-brown cups. The lichen in the lower photo was on a fallen branch in the humid area around the river viewing platform. The lichen in the lower photo was on a limb further along the trail where the air was drier.

The hiking trail climbed back up onto the ridge with open, drier woods with fewer lichens although I did find this.

For some reason I’m finding a lot of Old Man’s Beard lichen (Usnea strigosa) this year. Usually I find clumps lying along the trail. These photos clearly show the attachment of the lichen to a fallen tree limb and the fruiting bodies.

There were very few fungi high on the ridge towards the end of the trail I took.

The most artistic find of the day was a cluster of gilled mushrooms on this stump.

The final gem of the day was this sighting of some Witch's butter (Tremella mesenterica). It had dried a little in the wind but was a welcome splash of color in an otherwise brown woods.

So a trek just to enjoy the walk became a trek of discovery of a rich trove of fungal friends.

Harbins Park: Day of the Fungi (Part 1)

Yesterday saw the last of my Christmas lunches – believe it or not. Sometimes it’s challenging to connect with friends. No point in going back to work. The parking is a real challenge after lunch so I signed out for the afternoon.

I decided to go to the park just to walk. The forecast was for drizzle so I didn’t expect much. I dressed for rain and carried my camera in its small case, just in case. I thought I’d walk the equestrian trail that I had walked on my first visit to the park. I was opened-minded and decided to make up my walk as I went, depending on how I felt. That’s one of the great things about this park. It’s has a variety mix and match opportunities.

The route I took. I left that paved Meadow Trail to join the hiking trail (A) and followed this trail to the equestrian trail (B). I took the emergency exit trail (C) to the join the hiking trail again (D). This trail took me by the overlook platform (E) above the Alcovy River. Last time I walked the hiking trail, I switched back to the equestrian trail half way between the river overlook an F. This time, it was getting late and I rejoined the equestrian trail (F) and followed it back to where (A) I joined the trail originally. I followed the equestrian trail to G where I returned to the paved trail to complete the walk.

The recent rain and warmer temperatures, in the 60s F, had created perfect conditions to rejuvenate many of the fungi and lichens along the trail. Even so, I was surprised by the variety of fungi I saw. Along the equestrian trail (B) to (C); all on fallen tree trunks or limbs.

A bracket fungus. These were firm, polyporous brackets. A Trametes sp., possibly T. elegans.

A closer view of the same fungus.

This is a crustlike fungus on a fallen tree limb. The tawny brown fungus with a white margin with projecting runners fits the description of Coniophora puteana, a dry-rot fungus.

Many logs along this trail were covered with what appear to be a Parchment fungus, a Stereum sp. Stereum ostrea?

This 'frilly' fungus covered the limb. Is this another Stereum sp.? Stereum ochraceoflavum? Each fungus was paper thin; thinner than indicated by photos of Stereum ochraceoflavum that I’ve seen.

And a closer view.

After I turned onto the emergency exit trail at (C) and headed south towards the river, I saw fewer of the previous fungi and started to see lichens.
