Lauriomyces acerosus: a new record for the Americas

Abstract

The genus Lauriomyces is characterized by solitary or synnematous pigmented conidiophores containing acropetal chains of unicellular and hyaline conidia formed in an adherent head. The aim of the present study was to report a new record of Lauriomyces acerosus growing on the litter of Lafoensia pacari in southern Bahia, Brazil. The collections were carried out from October 2018 to July 2019. Twenty fallen leaves were collected in different stages of decomposition. The leaf samples were carefully washed in running water and incubated in humid chambers. The structures of the fungus were assembled in PVLG resin and observed under a light microscope. The identification was carried out by specific bibliographies. And based on morphology, it was possible to identify the fungus as L. acerosus, a new report of this species for the American continents
