Albemarlea Fuscidea Hueidea Maronea Maronora Fuscideaceae is a family of fungi that form symbiotic] relationships with algae to create lichens.

Fuscideaceae lichens are characterised by their reproductive structures, cup-like formations called apothecia, which can vary in colour from red to dark brown or black.

[1] In his Outline of the Ascomycota series (2006), Ove Eriksson included the genus Hueidea in Fuscideaceae based on its Fuscidea-type asci as the diagnostic character.

[4] In a recent proposal by Heidi Lie Andersen and Tor Tønsberg, published in late 2023, there has been a call to conserve the name Fuscidea over Maronea, to addressing a taxonomic and nomenclatural issue in the Fuscideaceae.

[12] In 2006, Miadlikowska and her team recommended placing the Fuscideaceae-Ophioparmaceae-Umbilicariaceae grouping into a distinct order, Umbilicariales, under the class Lecanoromycetidae, yet this classification was not officially adopted.

[13] Molecular work by Miadlikowska and colleagues in 2014 showed that the family occupies an outlying clade within the order Umbilicariales, which includes the Ophioparmaceae and Ropalosporaceae as well as the Umbilicariaceae itself.

It is not uncommon for these lichens to have a darker outline or base (prothallus), and some species may develop clusters of reproductive structures (soralia) on their surface.

Inside these structures, the supportive tissue (hamathecium) consists of sparsely to richly branched filaments (paraphyses), which often have coloured tips.

Fuscideaceae asci typically release eight or more spores, which are generally non-segmented (aseptate) or rarely divided once (1-septate), and range in colour from clear to pale brown.

[8] Genus Albemarlea contains a single species that is found exclusively in North Carolina's Albemarle-Pamlico Peninsula,[19] whereas New South Wales, Australia, is the only known location for the granite rock-dwelling Hueidea.
