Lasiosphaeriopsis is a lichen-dwelling (
lichenicolous) fungus placed within the
Coronophorales in a broad sense. It forms small, black, carbonaceous that sit on the surface of the
host rather than being immersed. These
fruiting bodies are usually clustered, short-stalked and irregularly , with a coarse, warted surface and one to several internal chambers. Each stroma bears an
ostiole (a minute pore) lined with
periphyses—fine sterile hairs that fringe the opening. The stroma wall is thick and stratified, built of dark brown, brick-like cells () that include tiny perforations often referred to as "Munk pores"; the cells become elongated within the stalk. Inside, the
asci are elongated, club-shaped and long-stalked. They are (with a single functional wall), lack a visible apical apparatus, and usually contain two to four spores.
Paraphyses (sterile filaments common in many ascomycetes) are absent. The
ascospores are broadly spindle-shaped and divided by three to four
cross-walls; they are brown overall but tend to be paler to nearly colourless at the ends. The spore surface is smooth and there is no surrounding gelatinous sheath. ==Species==
