(1849) Type genus Stictis Pers. (1800) The **Stictidaceae** are a [family](/source/Family_(taxonomy)) of [fungi](/source/Fungi) in the order [Ostropales](/source/Ostropales).[1] It has 30 genera and about 240 species. ## Taxonomy The family was [circumscribed](/source/Circumscription_(taxonomy)) by the Swedish mycologist [Elias Magnus Fries](/source/Elias_Magnus_Fries) in 1849.[2] ## Description Members of the Stictidaceae are diverse in their lifestyles, ranging from [saprotrophic](/source/Saprotrophic) (feeding on decaying matter) and [parasitic](/source/Parasitism) to [lichen](/source/Lichen)-forming organisms, and rare occurrences as [lichen dwellers](/source/Lichenicolous_fungus). Some species within this group show facultative lichenisation: they have the ability to switch between lifestyles, forming lichens when growing on bark, or living as saprotrophs, depending on their environment. The [thallus](/source/Thallus) of these fungi is typically crust-like in form. In cases where a [photobiont](/source/Glossary_of_lichen_terms#photobiont), or [photosynthetic](/source/Photosynthesis) partner, is present, it is usually of the [chlorococcoid](/source/Glossary_of_lichen_terms#chlorococcoid) type, which consists spherical [green algae](/source/Green_algae).[3] The reproductive structures, known as [ascomata](/source/Ascomata), have a range from [apothecial](/source/Apothecia) (open, disk-like) to [perithecial](/source/Glossary_of_lichen_terms#perithecial) (flask-like) forms. They can have various forms, from [biatorine](/source/Glossary_of_lichen_terms#biatorine), which are apothecial with a thalline margin, to [lecideine](/source/Glossary_of_lichen_terms#lecideine), which lacks a [thalline](/source/Glossary_of_lichen_terms#thalline) margin, or even [zeorine](/source/Glossary_of_lichen_terms#zeorine). Often, these structures have an inner crystalline layer within their margins. The internal structure of the ascomata features [paraphyses](/source/Paraphyses) – sterile filaments – that are unbranched and sometimes have swollen ends. These paraphyses are [amyloid](/source/Amyloid_(mycology)). [Periphysoids](/source/Glossary_of_lichen_terms#periphysoids), which are hair-like structures, typically line the outer part of the ascomata, known as the [excipulum](/source/Glossary_of_lichen_terms#excipulum).[3] The [asci](/source/Ascus) (spore-producing cells) are thin-walled with a small, apical structure protruding into the internal cavity, known as the [lumen](/source/Glossary_of_lichen_terms#lumen). These structures are non-amyloid and cylindrical in shape. Typically, each ascus contains eight ascospores, but some species may have more due to spore fragmentation. These spores are diverse in shape, ranging from [ellipsoid](/source/Ellipsoid) to filament-like, and are [hyaline](/source/Hyaline), meaning they are translucent. They have a variety of segmentations, from crosswise partitions to occasionally being multi-chambered ([muriform](/source/Glossary_of_lichen_terms#muriform)), and have thin [septa](/source/Septum) and walls. There is no known formation of [conidiomata](/source/Conidiomata), asexual reproductive structures, in this family.[3] ## Genera This is a list of the genera contained within the Stictidaceae, based on a 2022 review and summary of fungal classification.[4] Following the genus name is the [taxonomic authority](/source/Taxonomic_authority), year of publication, and the number of species: *[Robergea albicedrae](https://en.wikipedia.org/w/index.php?title=Robergea_albicedrae&action=edit&redlink=1)* *[Stictis cordylines](https://en.wikipedia.org/w/index.php?title=Stictis_cordylines&action=edit&redlink=1)* *[Thelopsis isiaca](https://en.wikipedia.org/w/index.php?title=Thelopsis_isiaca&action=edit&redlink=1)* - *[Absconditella](/source/Absconditella)* Vězda (1965) – 16 spp. - *[Acarosporina](/source/Acarosporina)* Sherwood (1977) – 5 spp. - *[Biostictis](/source/Biostictis)* Petr.
