Fennellomyces linderi CBS 158.54 was first isolated from poplin fabric in Florida, USA. It was originally described as Circinella linderi by Hesseltine and Fennell (1955). The type strain was deposited in the NRRL collection as NRRL 2342 (and a duplicate was deposited later as CBS 158.54). In 1975 the species was transferred to the genus Fennellomyces as the type species of the genus (Benny and Benjamin 1975). Species of Fennellomyces were initially classified within the family Thamnidiaceae based on morphological features, but molecular phylogenetic studies indicate that Thamnidiaceae is polyphyletic (O’Donnell et al. 2000; Walther et al. 2013). Recent phylogenetic results suggest that Fennellomyces belongs in the Lichtheimiaceae (Hoffmann et al. 2009, Hoffmann et al. 2013). Species of Fennellomyces produce multi-spored sporangia in which the sporangial wall dissolves at maturity, revealing a conspicuous columella (Figs. 1-2). In addition to bearing terminal multi-spored sporangia, the sporangiophore also bears persistent-walled sporangiola on recurved lateral branches (Fig. 3). The genome of Fennellomyces linderi was sequenced to help elucidate evolution of the early diverging fungi within the framework of the 1000 Fungal Genomes Project.
