Capillitium usually abundant, the threads slender, 2–2.5 µm in diameter, irregular, minutely warted or spinulose. Spores ochraceous yellow in mass, pale yellow by transmitted light, minutely roughened, 10–14 µm in diameter. Plasmodium watery white, yellowish, or rose-red.
Habitat: Dead herbaceous stems and leaves; occasionally occurring on bark

Notes: Typical fruitings of P. vermicularis, which consist of long, branched to somewhat anastamosing plasmodiocarps, are distinctive.
