Seen growing on and apparently parasitizing a genus Fomitopsis polypore.
Fruiting on Quercus agrifolia leaf and Pinus radiata needle.
Found in a rock moss. Length 136 µm.
Found in a rock moss. Length 200 µm.
Plasmodium white or pink. Sporocarpous and/or plasmodiocarpous, dispersed or in small groups, sessile or sub-sessile on a small base, spherical, pulvinate or terete, 0.2-1.0 mm diam. and up to a few mm long, opalescent rosy-lilac when fresh, changing to beige or iridescent yellow, green or blue-green. Peridium single, thin and translucent, pale ochraceous and either smooth or minutely punctate by TL. Dehiscence irregular. Capillitial threads 0.5-1.0 µm diam., very long, tangled and looped, with few connections to the peridium, threads protruding elastically and covered with small, ± spirally-arranged spinules or wartlets (oil-immersion). Spores rosy when fresh then beige, yellowish or colourless, 9-12 µm diam., covered with small spines or warts.
Sporocarps 250-500 µm tall, white or sometimes pink when fresh, white or pinkish when dry. Stalk 180-400 µm long, the basal part expanded and filled with granular matter, tapered to 1.5-3 µm diam. at the apex. Sporotheca 40-70 µm diam. Columella 3-10(-15) µm long. Capillitium a delicate, freely branching system arising mainly from the columella tip with numerous pointed free ends, branched but rarely anastomosed. Peridium remaining as a 4-9 µm diam. collar at the base of the sporotheca. Spore-mass white or pink. Spores hyaline, globose, 6-8(-10) µm diam., minutely roughened, bearing obscure spore-to-spore articular pads. Typically two spores adhere to the base of the columella.
Plasmodium watery white. Sporocarps scattered, stipitate, 0.6-1 mm tall. Stalk black and shining by reflected light, fibrous and reddish brown at base by TL, c. 60-65% of the total height, 48-132 µm wide at the base, 8-16 µm diam. at the apex. Sporotheca globose, 0.24-0.40 mm diam., dark brown. Columella c. 50-66% of sporotheca height. Capillitium dark, flexuose, arising from all parts of the columella, branched and anastomosed to form a surface reticulum with no or few free ends. Spore-mass dark coppery brown. Spores violaceous brown, very faintly warted to nearly smooth and having a paler and smoother area on one side, 7-10.5 µm diam.
Found on a rock moss. Length 190 µm.

Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile. Originally, protozoa had been defined as unicellular protists with animal-like behavior, e.g., movement. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behaviour, e.g. photosynthesis.
