Fungi named in 1942

Inonotus obliquus, commonly called chaga (; a Latinization of the Russian word ча́га), is a fungus in the family Hymenochaetaceae. It is parasitic on birch and other trees. The sterile conk is irregularly formed and resembles burnt charcoal. It is not the fruiting body of the fungus, but a sclerotium or mass of mycelium, mostly black because of a substantial amount of melanin. It is commonly marketed as a dietary supplement for various health benefits but lacks sufficient scientific evidence for safety or effectiveness, and quality can vary due to inconsistent processing and labeling.

Termitomyces is a genus of basidiomycete fungi known as termite mushrooms in Lyophyllaceae family farmed by fungus-growing termites. The fungi and the termites interdepend to live, as the termites house and culture the fungi, and the fungi in turn provide foods for the termites. Often after a raining, the fungi grow mushrooms, which are edible and highly regarded for their flavor.

Perenniporia is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood.

Termitomyces schimperi is a large mushroom associated with the termite species Macrotermes michaelseni. It grows in the northern part of Southern Africa, from northern Namibia up to Democratic Republic of Congo (DRC), eastwards to Malawi and Mozambique, and westwards to Ivory Coast. In Namibia it is commonly referred to by its Herero name Ejova (singular)/ Omajowa (plural). German Namibians refer to the mushroom as "Termitenpilz."

Pseudobaeospora is a genus of fungi in the family Tricholomataceae. A 2008 estimate placed about 20 species in the widespread genus.

Termitomyces microcarpus is a species of agaric fungus in the family Lyophyllaceae. An edible species, it is found in Africa and Asia, where it grows in groups or clusters in deciduous forests near the roots of bamboo stumps associated with termite nests.

Termitomyces eurrhizus species of agaric fungus in the family Lyophyllaceae native to Pakistan, India, Sri Lanka, Burma, southwestern China and Malaysia. The fungus has a symbiotic relationship with termites, its mushrooms growing out of mounds after periods of rainfall. It is eaten in Malaysia and the Indian subcontinent.

Paragyrodon is a genus of fungi in the family Paxillaceae. It is a monotypic genus, containing the single species Paragyrodon sphaerosporus. Paragyrodon was circumscribed by Rolf Singer in 1942.

Menegazzia subsimilis is a species of lichen in the family Parmeliaceae It is found scattered across the world, including Oceania (Hawaii, Solomon Islands), Asia (Japan, Papua New Guinea, Russia), Europe (Austria, Germany, Portugal), South America (Ecuador, Peru), the Caribbean (Dominican Republic, Jamaica) and North America (Canada, USA). It has recently been recorded for the first times in Tibet (2005), in the British Isles, and in Malaysia and Indonesia (2007). The lichen was originally described as Parmelia subsimilis by Swedish lichenologist Adolf Hugo Magnusson in 1941, based on

Menegazzia globulifera is a species of foliose lichen found in New Zealand, Australia, and southern South America. It was formally described as a species new to science in 1942 by Swedish lichenologist Rolf Santesson. The type specimen was collected north of Lago Fagnano (Tierra del Fuego, Argentina). The lichen is typically encountered as an epiphyte, but occasionally it has been recorded growing on rocks. Menegazzia globulifera contains usnic acid and lecanoric acid as major lichen products.

Menegazzia enteroxantha is a species of foliose lichen found in Australia. It was first formally described as a new to science by Swiss botanist Johannes Müller Argoviensis in 1896, as a species of Parmelia. Rolf Santesson transferred the taxon to genus Menegazzia in 1942.

Menegazzia aeneofusca is a species of lichen from South America, New Zealand, and Australia.

Helicogonium is a genus of fungi in the Ascomycota phylum.

Cladonia confusa is a species of lichen, native to and found in New Zealand, Australia, Africa and South America. It is one of many species of the genus Cladonia, collectively often referred to as fuzzy reindeer lichen. The species was described by Rolf Santesson in 1942.

Anguillospora is a genus of fungi belonging to the family Amniculicolaceae. It was circumscribed by Cecil Terence Ingold in 1942, with Anguillospora longissima assigned as the type species. It was found as a root endophytic fungus in the plant Equisetum scirpoides. It is related to the genera Amniculicola and Lophiostoma. The genus has a cosmopolitan distribution.

Physalospora abdita is a fungal plant pathogen that causes cankers on, among other species, mangoes, persimmons, maples, alders, and oaks. It is a saprobe specifically on oaks and causes twig blights of persimmon.

Penicillium resticulosum is an anamorph species of fungus in the genus Penicillium which produces notatin.

Paragyrodon is a genus of fungi in the family Paxillaceae. It is a monotypic genus, containing the single species Paragyrodon sphaerosporus. Paragyrodon was circumscribed by Rolf Singer in 1942.

Mycosphaerella angulata is a fungal plant pathogen infecting muscadine grapes. This pathogen causes the common disease angular leaf spot. Mycosphaerella angulate is an ascomycete in the fungi kingdom.

Meruliporia incrassata is a fungus that causes dry rot, predominantly in North America, where it can also be known by the diminutive "poria", which is also a recognized historical synonym for the genus.

Menegazzia platytrema is a species of lichen found in Australia.

Lagenulopsis bispora is an obligate fungal parasite that infects the leaves of conifers exclusively in the genus Podocarpus. L. bispora is a member of the family Coryneliaceae. It has been reported in Cuba, Fiji, Jamaica, Malawi, Mexico, and Uganda. Less commonly, it has also been found in South Africa.

Lactarius maculatipes is a member of the large milk-cap genus Lactarius in the order Russulales. The species was described as new to science by mycologist Gertrude S. Burlingham in 1942.
