Enterographa hutchinsiae (Leight.) A. Massal. s.l.

   Thallus crustose, thick, smooth or finely rimose, even, often forming elaborate widespreading mosaics, dark olive-green or dark grey-brown, dark brownish. (N.B. Margins of cracks or apothecia are sometimes tinged yellow); prothallus black, criss-crossing the thalli. Apothecia immersed, comma or sickle-like, lirelliform, short, irregular, not or dimly protruding, disc fully exposed, flat or slightly convex, black or grey-brown-black, matt. Ascospores fusiform, 4-8-septate, 24-30 x 4-5 µm. Pycnidia, dark brown punctiform. Photobiont: Trentepohlia. Thallus: C-, K-, KC-, Pd-. Rare, on shaded seepage tracks at the base of trees and the upper limit of roots of old deciduous trees of very humid oceanic woodlands. N.B.  Enterographa hutchinsiae ss. str. ss. auct. brit would be a saxicolous species on continuously damp rocks of riverbanks of oceanic woodlands and our understanding of this species is done sensu lato, for specimen different from Enterographa crassa which is much more common in our prospection area, with a green thallus and apothecia punctiform, mainly growing on bark of trees in sparse woodlands or in alignments and not in dark forests.  Enterographa elaborata ss. auct. bri. has  a paler thallus and apothecia long and sinuous, and larger ascospores.*
