Aspergillus restrictus

Aspergillus restrictus is a species of fungus in the genus Aspergillus. It is from the Restricti section.[3] The species was first described in 1931.[1] It is xerophilic, frequently found in house dust. Studies have suggested that it is an allergen implicated in asthma.[4][5] In 2016, the genome of A. restrictus was sequenced as a part of the Aspergillus whole-genome sequencing project - a project dedicated to performing whole-genome sequencing of all members of the genus Aspergillus.[6] The genome assembly size was 23.26 Mbp.[6]
