Taxa named by Frederic Clements

Dibaeis is a genus of lichen-forming fungi in the family Icmadophilaceae. The genus is widely distributed in tropical regions. Dibaeis was circumscribed in 1909 by Frederic Edward Clements with Dibaeis rosea as the type species. Several species were transferred from other genera in a 1993 publication.

Pronectria is a genus of fungi in the family Bionectriaceae. It consists of 44 species, all of which are lichenicolous. The genus was circumscribed by American plant ecologist Frederic Clements in 1931.

Pezoloma is a genus of fungi within the Leotiaceae family.

Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909. These lichens form pale grey-brown to olive-green crusts on tree bark and are characterized by elongated, pencil-like slits containing spores, with distinctive tiny spines on internal filaments that help distinguish them from similar genera. The genus includes about 50 species found primarily in tropical and subtropical forests worldwide, where they grow on living tree bark and serve as indicators of relatively undisturbed woodland environments.

Epilichen is a small genus of lichen-forming fungi in the family Rhizocarpaceae. These parasitic lichens live on other lichens, beginning as thin, crust-like patches that may break into small islands or scales, and in some cases produce no visible body at all except for their reproductive structures. They reproduce through black, disc-shaped fruiting bodies that contain distinctive brown spores with a "doughnut ring" appearance, and can eventually take over the space occupied by their host lichen once it dies.

Naeviella is a genus of fungi in the family Calloriaceae. It has three species. The genus was circumscribed by American plant ecologist Frederic Clements in 1909.

genus of fungi

Lasiosphaeris is a genus of fungi in the Sordariomycetes class (subclass Sordariomycetidae) of the Ascomycota. The relationship of this taxon to other taxa within the class is unknown (incertae sedis), and it has not yet been placed with certainty into any order or family.

Myriolecis is a genus of lichen-forming fungi in the family Lecanoraceae. These lichens typically form thin, crust-like patches on rocks, bark, or soil, and reproduce through small disc-shaped structures that contain spores. The genus was reinstated in recent years when DNA studies showed that these species form a distinct group separate from the closely related genus Lecanora. Phylogenetic studies place Myriolecis in the MPRPS clade of Lecanoraceae, close to Protoparmeliopsis.

Discostroma is a genus of fungi in the family Amphisphaeriaceae.
