Type speciesHydea pygmea (Kohlm.) K.L. Pang & E.B.G. Jones

Notes – Abdel-Wahab et al. (2010) transferred Cirrenalia pygmea to Hydea based on phylogenetic analyses of combined LSU and SSU sequence data. Hydea pygmea is commonly found on mangrove wood, especially growing on Rhizophora species (Abdel-Wahab et al. 2010). Hydea pygmea is different from all other cirrenalia-like species by the dark-brown to black hooked nature of the conidia and by the internal proliferation of the conidia (Kohlmeyer & Kohlmeyer 1979).
