It is a monotypic genus, containing the single species Faerberia carbonaria, which is commonly known as the firesite funnel due to its habitat of burned soil.

[2][3] This species was originally described in 1805 as Merulius carbonarius by botanists Johannes Baptista von Albertini and Lewis David de Schweinitz.

As a somewhat rare, monotypic, gilled polypore with a habitat of burned soil it is therefore quite an unusual species.

It may grow in small trooping groups or be found individually but it is an uncommon find appearing through summer and autumn.

[citation needed] Whilst it is an edible mushroom, it is regarded as a poor choice due to its tough texture, mild taste and general rarity.
