Index Fungorum number: IF543118; Facesoffungi number: FoF 08400; 1 morphological species; 1 species with sequence data.
Saprobic on decayed driftwood in intertidal zone, mainly on mangrove wood. Asexual morph: Hyphomycetous. Hyphae septate, branched, brownish-gray. Conidiophores obsolete. Conidia acrogenous, solitary, helicoid, twisted 1/2–1 times, 3-to 4-septate, brownish-gray to black, not or faintly constricted at the septa, cells larger in diameter and more pigmented at the apex than at the base. Sexual morph: Undetermined (Abdel-Wahab et al. 2010).
Type species: Hydea pygmea (Kohlm.) K.L. Pang & E.B.G. Jones, in Abdel-Wahab, Pang, Nagahama, Abdel-Aziz & Jones, Mycol. Progr. 9(4): 549 (2010)
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).
