Hypocenomyce

Hypocenomyce is a genus of lichen-forming fungi in the family Ophioparmaceae. Species in the genus grow on bark and on wood, especially on burned tree stumps and trunks in coniferous forest. Hypocenomyce lichens are widely distributed in the northern hemisphere.

==Taxonomy== The genus was circumscribed in 1951 by French lichenologist Maurice Choisy to contain the single species Hypocenomyce scalaris, a lichen that was first formally described by Erik Acharius in 1795. Choisy's original concept of the genus featured a squamulose thallus, adnate apothecia of the lecideine type (i.e., lacking algae and an amphithecium, with a black carbonized margin as in the genus Lecidea) and pycnoconidia that are short, straight, and cylindrical. Norwegian lichenologist Einer Timdal revised the genus in 1984, describing two new species to bring the total Hypocenomyce species up to ten. Since then, two new species have been described, and several have been transferred to other genera.
