Birding/biota trip to Weymouth Woods Preserve in Moore County, NC. I finally edited all of these after puzzling through some ID's on plants and fungi. This odd little fungus was growing out of a dry log in a recently burned area. Poking around various references, it looks very close to...
Xylaria longiana

Definitive species-level identification would no doubt require expert examination of the spores, or DNA barcoding, etc. However the form looks pretty distinctive.

Happy Arachtober 3rd!

Leaf Beetle - Bassareus detritus (female; 5 mm)
References:

• BugGuide: bugguide.net/node/view/221248
• Ciegler, Leaf and Seed Beetles of South Carolina (Clemson Univ., 2007), p. 185
• Evans, Beetles of Eastern North America (Princeton University Press, 2014), p. 451

Another series of this beetle, found on vegetation in a suburban deciduous woodland. Length is just under 5 mm. Quoting Ciegler , p. 172, key to genera of Cryptocephalinae:
10(9) Anterior edge of proepisternum laterally sinuous or toothed, in many specimens difficult to see (Fig. 285); abdominal sternum 1 of male excavated in middle and with large spine on each side; length 3.2-5.5 mm --> Bassareus, p. 184
Does not seem to have those spines, so must be a female.
I have trouble seeing the sinuous/toothed edge of the episternum in this specimen, but everything else is consistent. This one lacks the spines on abdominal sternum 1, I think, so it should be a female.
Confirmations/corrections always appreciated, of course.
Specimen to be retained for barcoding. Also posted at:

Edit. Working on seeing some details distinctive for the genus based on consultation with an expert. Color pattern of this species is distinctive, at any rate.

Click beetle - Aeolus scutellatus (~6 mm)

Apparently not the very similar Aeolus mellillus. I think(!) I can see the conical scutellum which is noted as the distinguishing feature of scutellatus by entomologists commenting on BugGuide and iNaturalist.
Update 11/14/22. Added detail image of scutellum.

Out walking on a woodland trail in suburban Durham NC (USA), a coupled pair of flies landed on my arm. I captured them for some detailed studio photos. They appear to be...
March Flies - Bibio articulatus (male, 6 mm length)
bugguide.net/node/view/371338
Quoting BugGuide:
The most common of the species with mostly red legs, black body (but female thorax red on top), and inner spur of fore tibia as long as outer. Bibio xanthopus is larger with a slightly shorter to much shorter inner spur. Females can be identified by the combination of equal spurs and dark orange to bright red thorax.

Leaf fungus on Water Oak (Quercus nigra) found by Tracy. The fungal hyphae are 1-1.5 mm long. A detail frame shows some interesting webbing among the hyphae. No doubt there were was an insect (or other arthropod) lurking there that made the web, but I did not notice any.
I am happy to hear any ideas on the ID of this fungus!
Shown to me by expert naturalist @tracysfeldman, as were most other finds this day.
