Undescribed, aff. myrmecophila, on carpenter ants.
Same locality as last year - found in soil and moss, in a wet creekbed in conifer forest.
Substrate: on slime mold on living liverwort on log beside river
Habitat: Northwest Andean montane forest (NT0145)
Collectors: D. Newman & R. Vandegrift
Collection #: RLC1210
Photomicrography and molecular data forthcoming
Found on larvae (diptera?) inside of an Alder log.
Found under oak log
Growing off of what looks like a sclerotia or maybe Peziza ellipsospora
Found buried in gravel a couple inches away from water in a small creek. Growing on undetermined arthropod - maybe some aquatic insect larva. Seems to be Polycephalomyces formosus or something close.
Unknown host, but host is wrapped in brown fibers as show in 3rd photo. This specimen was very small, and we had to be very delicate just to get this much. Collected by John Plischke: https://www.inaturalist.org/observations/147594895
? Not sure what kind of leaf
Undescribed species of Ophiocordyceps on larva of Polyphylla decemlineata
Growing on the fallen, dead flowers of a bamboo (Dendrocalamus strictus.)
Probably Kimflemingiae. Two ants on the same tree.

This observation is for the fungus. The host seems to be some kind of orthopteran.
A magnificent fruiting along several feet of a log. Fruiting bodies up to 2.5cm long. Appeared distinctly greenish yellow in situ, but plain yellow after being pulled out of the shadows of the log. Gooey, sticky, adhering to anything that touches them, specimens drying to a shriveled, translucent puddle. Only beech, maple, cucumber magnolia immediatly surrounding the log, but the presence of the Callistosporium, and the good macroscopic match to the description of G. luteodiscus from Tsuga, suggests the log might have been a conifer.

@damontighe, @leptonia, a fungus or slime mold of some kind? On Quercus agrifolia.
Found inside of a hollowed-out fallen log (pic 5). Possibly Akanthomyces gracilis hyperparasitizing an undetermined Ophiocordyceps sp.
Under oaks, small, interestingly fluorescent

on what looks like a Trachelas sp. host
For the big mushroom, ~12” tall with a 6” diameter cap.
F#377
Reminiscent of Cordyceps sensu lato, no host found. Some sort of eggs found at base of mycelial threads?

Ref 10142022-09144. Attacking black whiteflies, possibly Aleuroplatus but difficult to tell with these specimens.
Unfamiliar… On a Magnolia cone. Didn’t extract.

Growing on Panicum sp. fruit
Isolated from:
https://www.inaturalist.org/observations/187958687
Emerging from large decaying hardwood log in the bottom of low moist woodland draw dominated by paw paw trees. Locally abundant on log and absent on nearby logs. Specimens appear to be parasitizing Ophiocordyceps variabilis and/or directly competing for its larval host.

Growing on a deer skull that was partially buried in the dirt. Macro photos by John Plischke. Fungus is florescent in 365nm UV light.

The cap has an interesting crunchy texture.
Growing on well decayed wood.
Spores smooth, inequilateral, 10.5 – 13 × 5 – 6.5 µm, with 1 or 2 oil droplets per spore. 8 spores per ascus. Asci walls invisible in KOH.
Spore measurements:
10.6 [11.4 ; 12] 12.8 × 4.8 [5.5 ; 6] 6.6 µm
Q = 1.7 [2 ; 2.2] 2.4 ; N = 15 ; C = 95%

Found on dead wood in a coffee plantation in Colombia.
