Richard Clinton Harris

American lichenologist (1939-2021).

Richard Clinton "Dick" Harris (December 6, 1939 – May 10, 2021) was an American lichenologist associated for most of his career with the New York Botanical Garden. He was especially known for his work on pyrenocarpous lichens and lichenicolous fungi and for his wide field knowledge of the lichen flora of eastern North America. Over more than five decades he described over 200 new species and infraspecific taxa, 14 genera, and three families of lichen-forming and lichenicolous fungi, and became an influential figure in North American organismal lichenology.

Naetrocymbaceae Höhn. ex R.C. Harris 1995
fungi family in the class dothideomycetes
The Naetrocymbaceae are a family of fungi in the order Pleosporales. Some members of the type genus, Naetrocymbe, form lichens.
Pyrenula pyrenuloides (Wart Lichen) (Mont.) R.C. Harris 1989
fungi species in the pyrenulaceae family
Pyrenula pyrenuloides, also known by the common name wart lichen, is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. It has a pantropical distribution.
Porina scabrida (Hairy Pimple) R.C. Harris 1995
fungi species in the porinaceae family
Porina scabrida is a species of crustose lichen in the family Porinaceae. First described in 1995 by American lichenologist Richard C. Harris, it is characterized by its pale olive-tan crustose thallus with distinctive cylindrical isidia. The species is found in eastern North America, ranging from Ontario, Canada through the southeastern United States, where it grows primarily on tree bark in humid environments such as hardwood-cypress swamps and mesic forests. It can be found at various elevations from sea level up to 435 m (1,427 ft), typically in protected areas but occasionally in
Porina heterospora (Southeastern Pimple Lichen) (Fink) R.C. Harris 1980
fungi species in the porinaceae family
Porina heterospora is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae. It occurs in the southeastern United States.
Candelariella efflorescens (Powdery Goldspeck) R.C. Harris & W.R. Buck 1978
fungi species in the candelariaceae family
Candelariella efflorescens, commonly known as the powdery goldfleck lichen, is a sorediate, corticolous (bark-dwelling) crustose lichen in the family Candelariaceae. It is widespread in temperate parts of North America and Europe and has also been confirmed from Asia (Pakistan) by DNA sequence data. The thallus consists of minute yellow areoles that quickly "effloresce" into fine yellow soredia to form a continuous powdery crust; fruiting bodies (apothecia) are rare and small. When fertile, the species has multispored asci (typically 24–30 ascospores), a character separating it from several
Anthracothecium prasinum (Anthracothecium Lichen) (Eschw.) R.C. Harris 1987
fungi species in the pyrenulaceae family
Anthracothecium prasinum is a corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. It has a pantropical distribution, occurring across tropical regions. It forms black, carbonized (blackened) perithecioid fruiting bodies (pseudothecia) that produce brown, muriform (multichambered) ascospores.

Lepraria caesiella R.C. Harris 2005
fungi species in the stereocaulaceae family
Lepraria caesiella is a species of leprose lichen in the family Stereocaulaceae. It forms a thin, gray-blue powdery crust composed of granular aggregations and lacks a true cortex or lobes. The species is widespread throughout northeastern North America, occurring primarily on tree bark, especially hardwoods like oaks, though it can also be found on non-calcareous rocks in sheltered locations. It was formally described by Richard C. Harris in 2005 and is characterized by its production of atranorin, zeorin, and pallidic acid. phylogenetics studies have helped distinguish it from the
Eopyrenula R.C. Harris 1973
fungi genus in the dacampiaceae family
Eopyrenula is a genus of lichen-forming fungi in the family Dacampiaceae. It comprises six species. The genus was established in 1973 by Richard C. Harris to separate these lichens from the related genus Pyrenula, based on differences in their reproductive structures and spore characteristics. Eopyrenula species are found on tree bark in temperate regions, particularly in Europe and North America, where they form thin, pale grey crusts dotted with tiny dark fruiting bodies. The genus occupies an uncertain position in fungal classification, with its family placement remaining provisional

Arthopyrenia degelii R.C. Harris 1995
fungi species in the trypetheliaceae family
Arthopyrenia degelii is a species of corticolous lichen in the family Trypetheliaceae. It was formally described as a new species by Richard Clinton Harris in 1995. The type specimens, originally collected in 1939 by Swedish lichenologist Gunnar Degelius (for whom the species is named), were found growing on Hamamelis in the Great Smoky Mountains of Tennessee. The lichen forms brown, rarely tan, blotches on smooth bark. It has superficial ascomata that are range in shape from hemispherical to flattened, and measuring 0.3–0.5 mm diameter. The asci are narrowly elliptical, measuring 48–60 by
