Costantinella terrestris

Basal hyphae with simple septa, pigmented yellowish-brown, ornamented with numerous dark brown warts.

These basal hyphae terminate in conidiogenous hyphae or conidiophores, very abundant and branched, with conidia arising from the terminal cell, which is slightly curved and ventricose.

These conidiophores produce smooth, completely spherical, hyaline, thin-walled conidia.
