Purpureocillium lilacinum (Thom) Luangsa-ard, Houbraken, Hywel-Jones & Samson 2011
fungi species in the ophiocordycipitaceae family
Purpureocillium lilacinum is a species of filamentous fungus in the family Ophiocordycipitaceae. It has been isolated from a wide range of habitats, including cultivated and uncultivated soils, forests, grassland, deserts, estuarine sediments and sewage sludge, and insects. It has also been found in nematode eggs, and occasionally from females of root-knot and cyst nematodes. In addition, it has frequently been detected in the rhizosphere of many crops. The species can grow at a wide range of temperatures – from 8 to 38 °C (46 to 100 °F) for a few isolates, with optimal growth in the range 26
Moniliophthora H.C. Evans, Stalpers, Samson & Benny 1978
fungi genus in the marasmiaceae family
Moniliophthora is a genus of fungi in the family Marasmiaceae. The genus was described in 1978 with M. roreri as the type species. This fungus, formerly known as Monilia roreri, causes frosty pod rot, a serious disease of Theobroma cacao. Moniliophthora is closely related to the genus Crinipellis, also having distinctive tiny hairs on the cap surface, but is distinguished by having a flexible stem and a reddish coloration of the fruiting body.

fungi species in the marasmiaceae family
Moniliophthora roreri is a basidiomycete fungus that causes frosty pod rot disease, one of the most serious problems for cacao (Theobroma cacao— the source of chocolate) production in Latin America.

Aspergillus felis Barrs, van Doorn, Varga & Samson 2013
fungi species in the aspergillaceae family
Aspergillus felis is a heterothallic species of fungus in the genus Aspergillus which can cause aspergillosis in humans, dogs and cats. It was described for the first time in 2013 after being isolated from different hosts worldwide (North and South America, Europe, Africa, Northeast Asia, and Asia-Pacific). The first host infected was a domestic cat with invasive fungal rhinosinusitis who gave its name to this new Aspergillus as Felis is a genus of cats in the family Felidae. Apsergillus felis was then described in a dog with disseminated invasive aspergillosis and a human patient with
