Inside a log heavily miceliated by other fungi. On coleoptera larva. Ñ
Host is an unidentified insect larvae, found growing from the cut end of a well decayed and wet log (Silver fir seems most likely but almost completely debarked) The part of the log it was in was the lowest, wettest sector of the log on the downhill end.
On a lepidopteran caterpillar, it would seem.
On Metarhizium atrovirens.

Rich Tehan: "That's surely the Torrubielloid sexual morph of something in Cordycipitaceae, likely Gibellula or Akanthomyces"
Hyperparasite on Ophiocordyceps cf crinalis. Likely undescribed Pleurocordyceps sp. ID by Richard Tehan.
Collected from ground surface leaf litter in rain. Maybe tenuipes that has been washed by the rain. Stems are very orange, though, as pictured. Attached to a robust lepidopteran pupa.
Growing from a very large grub in a pine thicket. Lots of ferns nearby, a small creek, several downed pine logs too. I literally got out of my car, walked ten feet into the thicket and this was between my feet when I looked down.
Camptonotus carolinensis infected with ophiocordyceps in its asexual (Hirsutella) phase and the new white growth is another fungus, a hyperparasite.
Host: on adult beetle (Coleoptera)
Habitat: montane to high-montane, humid, secondary mountain forests
Ecoregion: Bolivian Yungas (NT0105)
Collectors: D. Newman, P. Kaishian, L. Deininger, D. Ettlinger & T. Padilla
Collection #: CoHo008
On Olyra latifolia (Bambusoideae): https://www.inaturalist.org/observations/214283434
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.

Ergots from observation https://www.inaturalist.org/observations/201898440 were stratified in freezer and in september placed in flowerpot in garden. The fruitbodies started growing in january, the growth is very slow.
Just amazing! Parasitizing Ten-lined June beetle (Polyphylla decemlineata) on an open slope of sand. Insitu, already exposed when found
Bird dung crab spider
Entomopathogenic fungi. Grows in the nervous system of a host insect, altering its behaviour. Once the environmental conditions are right, the mushroom will fruit from the insect, digesting it and releasing spores above the leaf litter.
Entomopathogenic fungi, found growing on a Coleoptera larvae, shown in later photos
Collected by Laurie H. Jaegers. Growing singly on a dead coleopteran larva embedded in a log.

The only Akanthomyces tuberculatus I ever found on Scoliopteryx libatrix, all other were on Triphosa dubitata. Found in old mine.
Looks like it’ s coming from or near insect eggs?

Small club protruding from well-decayed log. White mass (host?) found inside log.
Reminiscent of Cordyceps sensu lato, no host found. Some sort of eggs found at base of mycelial threads?

Parasitized weta under a rock at about 1000m asl in boulder field.
Unfortunately I wasn't aware what I've found at the time and didnt dig up the host.
On buried insect in soil under duff layer. Found a couple hundred feet below receding snow line. Morchella fruiting in vicinity.
P. gracillioides or gracilis
Large, on fallen conifer, either Douglas fir or grand fir
Fruiting off Cricket deep within a small hole
Lots of specimens in this location all fruiting off beetles slightly beneath the soil surface
Fruiting off larvae in the soil
Host buried loosely in top of decaying log.

Inat's computer vision seems to convey Ophiocordyceps robertsii, which is a good comparison except for location. The caterpillar was completely mummified. It was hardened and intact. It was buried under a moss mound on the ground that includes what species I believe to be Thuidium delicatulum. I just happened to see the stroma above ground and commenced a gentle dig and found the caterpillar host just beneath the surface. This was in cove forest habitat near a stream in the ground. Nearby trees are Birch, Hemlock, Pine, Oak, and a nice diversity of other trees and plants.
