Question: Does the genus Scaevola or the genus Nothofagus contain more species?
Context: "Psathyloma" is a genus of two species of mushroom-forming fungi in the family Hymenogastraceae.  Used informally among New Zealand-based mycologists since 1997, the genus was formally circumscribed in 2016 with "Psathyloma leucocarpum" as the type species.  The genus name, which combines "Psathyrella" and "Hebeloma", alludes to the morphological similarity of the fruit bodies.  Both species in "Psathyloma" are found in New Zealand, where they fruit on the ground in "Nothofagus" forests. Scaevola is a genus of flowering plants in the "Goodenia" family, Goodeniaceae.  It consists of more than 130 tropical species, with the center of diversity being Australia and Polynesia. Pearsonomys annectens, also known as Pearson's long-clawed akodont or Pearson's long-clawed mouse, is a species of rodent in the tribe Abrotrichini of family Cricetidae.  It is the only species in the genus Pearsonomys.  Molecular data suggests that its closest relative is "Geoxus valdivianus".  This rodent is endemic to Chile, where it is found in "Nothofagus" forest of the Valdivian temperate rainforest ecoregion.  The genus is named after American zoologist Oliver Payne Pearson. Misodendrum is a genus of hemiparasites which grow as mistletoes on various species of "Nothofagus".  Its species are all restricted to South America.  The name of the genus is incorrectly spelt in a number of ways, including "Misodendron" and "Myzodendron". Scaevola hookeri, the creeping fan-flower or alpine fan-flower, is a prostrate perennial herb in the family Goodeniaceae.  It is native to eastern Australia.  Leaves are 6 to 50 mm long and 2 to 15 mm wide.  Flowers are white or blue with a yellowish throat and appear between December and March in the species native range.  The species was first formally described by W.H. de Vriese in 1850 in "Nederlandsch Kruidkundig Archief" and given the name "Merkusia hookeri".  The species was transferred to the genus "Scaevola" in 1856.  It occurs in grassland and woodland in high altitude areas in Victoria, New South Wales, Tasmania, and also South Australia where it is listed as "endangered". Artomyces nothofagi is a species of coral fungus in the family Auriscalpiaceae.  Found in southern Chile, it was described as new to science in 2015 by Richard Kneal and Matthew Smith.  The specific epithet "nothofagi" refers to the substrate it grows on, "Nothofagus dombeyi".  The species distinguished from other "Artomyces" species by a combination of smooth spores, largely unbranched fruitbodies, and gloeocystidia that extend beyond the hymenium.  Molecular phylogenetic analysis confirms "A. nothofagi" species is genetically distinct from other members of its genus. Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia).  The species are ecological dominants in many temperate forests in these regions.  Some species are reportedly naturalised in Germany and Great Britain.  The genus has a rich fossil record of leaves, cupules and pollen, with fossils extending into the late Cretaceous and occurring in Australia, New Zealand, Antarctica and South America.  In the past, they were included in the family Fagaceae, but genetic tests revealed them to be genetically distinct, and they are now included in their own family, the Nothofagaceae (literally meaning "false beeches" or "bastard beeches"). Nothojafnea is a genus of two species of cup fungi.  It was originally described by Indonesian mycologist Mien Achmad Rifai in 1968 to contain the type species "Nothojafnea cryptotricha", found in Australia. " N. thaxteri", known from Chile and Argentina, was added to the genus in 1971.  Both species are thought to be ectomycorrhizal; "N. cryptotricha" associates with Myrtaceae, while "N. thaxteri" is found with "Nothofagus". Sphictostethus is a genus of pepsine spider wasps which has a dispersed southern Pacific distribution which encompasses Chile, eastern Australia, Tasmania, and New Zealand, and is very similar to the distribution of the southern beeches of the genus "Nothofagus".  The type species is "S. gravesii", but the genus's greatest diversity is in Australia, especially in the more humid and temperate south east, with one species, "S. insularis", endemic to Lord Howe Island. Clavulina is a genus of fungi in the family Clavulinaceae, in the Cantharelloid clade (order Cantharellales). .  Species are characterized by having extensively branched fruit bodies, white spore print, and bisterigmate basidia (often with secondary septation).  Branches cylindrical or flattened, blunt, pointed or crested at apex.  Hyphae with or without clamps.  Basidia cylindrical to narrowly clavate, mostly with two sterigmata which are large and strongly incurved.  Spores subspherical or broadly ellipsoid, smooth, thin-walled, each with one large oil drop or guttule.  The genus contains approximately 45 species with a worldwide distribution, primarily in tropical regions.  Species of "Clavulina" are mostly ectomycorrhizal.  A recent study has identified Clavulina to the genera level as present on "Nothofagus menziesii" adventitious roots
