Found in a small pool of the Russian River after a rain storm, grazing on a Caddis fly case.
Found in a river gravel pool. Cuticular areoles absent, bilobed posterior of male with a transverse crescent just anterior of cloaca.
On a piece of rotting wood. Acrcyria?
On a piece of rotting wood. Fruiting bodies sessile.
Many on a piece of moldy wood.
Grove of large sized single trunked trees, no leaves. They are right along the bank in the 15000 blk of River Road. (There are some even larger trees, huge, in the Sunset Beach Regional Park).
I'm not all sure about this one. There are many stiff upright hairs on a rotting tree branch. When they are disturbed, a white mist of spores is released. Close up, the spores are 9 x 3 µm. There is little evidence of an original thallus.
Found as an ectoparasite of a Tengellidae spider. Length 1 mm.

"Members of the Neuropteran family Mantispidae, subfamily Mantispinae, are predators in the egg sacs of spiders, draining egg contents through a piercing/sucking tube formed by modified mandibles and maxillae. First-instar mantispids use two strategies to locate spider eggs: Larvae may burrow directly through the silk of egg sacs they find, or they may board and be carried by female spiders prior to sac production, entering the sac as it is being constructed. Mantispids that board spiders usually adopt positions on or near the pedicel; some species may enter the spider's book lungs. Larvae maintain themselves aboard spiders by feeding on spider blood . Transfers of larvae from spider to spider are possible during spider mating or cannibalism. All of the
major groups of hunting spiders are attacked by spider-boarding mantispids; the egg sacs of web-building species are also entered by egg-sac penetrators".
