Trogia

Trogia is a genus of fungi in the family Marasmiaceae. It is named after a Swiss mycologist Jacob Gabriel Trog. The genus contains about 20 species that are widely distributed in tropical areas.

==Taxonomy== The genus was first circumscribed by Elias Magnus Fries in 1835. He set the type species as Trogia montagnei, a species that had been described by French mycologist Camille Montagne in 1834 as Cantharellus aplorutis. The type has since been lost, and as a result, there has been some historical disagreement as to the boundaries of the genus. The British botanist Edred John Henry Corner emended the genus in 1966 to include 56 species. Rolf Singer disagreed with this broad species concept in the fourth edition of his Agaricales in Modern Taxonomy (1986), and only included three species: T. cantharelloides, T. buccinalis, and T. montagnei. He considered most of the species included by Corner as better placed in genera like Hemimycena, Mycena, Gerronema, Hydropus, and Hymenogloea. Corner later defended his species concept in a 1991 publication.
