Juncigenaceae is a family of ascomycetous marine based fungi within the order of Torpedosporales in the subclass Hypocreomycetidae and within the class Sordariomycetes.

[18] The new species of Elbamycella was found for the first time underwater, in association with the seagrass Posidonia oceanica and also the brown alga Padina pavonica, two different organisms that were sampled in close proximity.

[23][3] Species within the Juncigenaceae family have a sexual morph with perithecial (flask shaped opening) ascomata that are globose, subglobose, ovoid or pyriform (pear-shaped).

They are immersed, erumpent to superficial (in the host tissue), subcoriaceous to coriaceous (leather-like), olivaceous-brown, brown to dark–brown to black, hyaline (glass-like) to yellow-orange to reddish-brow (in colour).

The paraphyses (support structures) are numerous, narrow, branched or unbranched, persistent, connected to the apex and base of the peridium or catenophyses (pseudoparenchymatic chains of cells).

The Asci are 8–spored, unitunicate (single-walled), thin–walled, persistent, clavate (club-shaped), cymbiform (shaped like a boat), cylindrical to fusiform (spindle-shaped), short pedicellate (small stemmed), with or without an apical ring.

The ascospores are 1–3 seriate (arranged in rows), hyaline, ellipsoidal, clavate to fusiform (in shape), unicellular, or 1–4–septate (walled), with or without equatorial and polar or sub-polar appendages.

They have conidiogenous cells that are non–specialized, short, light to dark brown (in colour), lateral, solitary, helicoid (spiral shaped) and septate.

[25] While Juncigena adarca is only found on the senescent leaves (decaying) of Juncus roemerianus,[26][10] on the Atlantic coast (U.S.A.: North Carolina).
