Platycarpa is a genus of fungus in the order Platygloeales, containing the single species Platycarpa polypodii. The species forms effused basidiocarps (fruit bodies) on ferns, on which it is parasitic. The known host for Platycarpa polypodii is a fern in the genus Polypodium. The fungus parasitizes host leaves, producing basidiocarps as small whitish patches covering the sori. Microscopically, the basidia are auricularioid (tubular with lateral septa) and emerge from thin-walled probasidia. The species was originally described by American mycologist John N. Couch based on a collection from

Pringsheimiella is a genus of green algae, in the family Ulvellaceae. The genus name of Pringsheimiella is in honour of Nathanael Pringsheim (1823–1894), who was a German botanist. The genus was circumscribed by Franz Xaver Rudolf von Höhnel in Ann. Mykol. vol.18 on page 97 in 1920. Several species have been moved into other genera; P. crenulata (Lami) Nielsen & McLachlan, 1986 now accepted as Ulvella crenulata R.Lami, 1935 P. marchantiae (Setchell & N.L.Gardner) Schmidt & Petrak, 1935 accepted as Ulvella marchantiae (Setchell & N.L.Gardner) R.Nielsen, C.J.O'Kelly & B Wysor, 2013 P.

Coelomomyces psorophorae is a species of aquatic fungus in the family Coelomomycetaceae. It is a parasite of mosquito larvae. Its two-host life cycle involves alternating between mosquitoes and small aquatic crustaceans (copepods), with different reproductive stages occurring in each host. The fungus essentially hijacks the mosquito's body systems, growing inside the larva and eventually producing spores that can survive harsh environmental conditions. Research on this species has provided insights into how parasitic fungi evolve specialized strategies to exploit multiple hosts in aquatic

Coelomomyces elegans is a species of mosquito parasitic fungi, in the genus Coelomomyces. It has been found in Culex gelidus mosquitoes, in Matara, Sri Lanka. It is distinguishable from other species of Coelomomycetaceae by its resting sporangia, which are ornamented by circular depressed areas with papillae. Other distinct features include prominent vertical striae within ridges and a dehiscence split bordered by papillae.
