Yeast surveys associated with different bromeliads in north-eastern Brazil led to the proposal of two novel yeast species, Carlosrosaea hohenbergiae sp. nov. and Carlosrosaea aechmeae sp. nov., belonging to the Tremellales clade (Agaricomycotina, Basidiomycota). Analysis of the sequences of the internal transcribed spacer (ITS) region and D1/D2 domain of the LSU rRNA gene suggested an afnity with a phylogenetic lineage that includes recently reclassified Carlosrosaeavrieseae. Six isolates of the novel species were obtained from different bromeliad species collected in three Atlantic Forest fragments in Alagoas state, Brazil. Ca. hohenbergiae sp. nov. differs by 69 and 12 nucleotide substitutions in the ITS and D1/D2 domain, respectively, from Ca. vrieseae. The type strain is UFMG-CM-Y405T (=BSB 34T=CBS 14563T), Mycobank 819227. Ca. aechmeae sp. nov. is represented by one strain isolated from Aechmea constantinii leaves. Ca. aechmeae sp. nov. differs from the related species Ca. hohenbergiae and Ca. vrieseae by 36 and 65 nucleotide substitutions, respectively, in the ITS region and by 12 and 15 nucleotide substitutions in the D1/D2 domain, respectively. The type strain of Ca. aechmeae sp. nov. is UFMG-CM-Y6095T (=BM 94T=CBS 14578), Mycobank 819228.
