Phaeocandelabrum, a new genus of anamorphic fungi to accommodate Sopagraha elegans and two new species, Ph. callisporum and Ph. joseiturriagae
Phaeocandelabrum anam. gen. nov. is established to accommodate Sopagraha elegans, Ph. callisporum sp. nov. found on dead leaves of Cupania paniculata (Sapindaceae) and on the decaying leaf of an unidentified dicotyledonous plant in Brazil, and Ph. joseiturriagae found on decaying leaves of unidentified dicotyledonous plants in Brazil and Venezuela. Phaeocandelabrum callisporum is distinguished by complex, brown conidia composed of 2 globose, brown to dark central cells; 7–10 secondary hemispherical cells and, on each secondary cell, 3–4 hemispherical satellite cells, each with 5 simple, incurved branches. Phaeocandelabrum joseiturriagae is characterized by more less broadly Y-shaped to irregular brown conidia, each with a basal cell and two branches composed of 5–7 subglobose to globose cells, with 8–14 secondary cells each subtending 3–5 dichotomous or trichotomous minute tubercles. All three species are described and illustrated.
