The '''Stictidaceae''' are a [[Family (taxonomy)|family]] of [[fungi]] in the order [[Ostropales]].<ref name="CoL"/> It has 30 genera and about 240 species.
==Taxonomy== The family was [[circumscription (taxonomy)|circumscribed]] by the Swedish mycologist [[Elias Magnus Fries]] in 1849.<ref name="Fries 1849"/>
==Description== Members of the Stictidaceae are diverse in their lifestyles, ranging from [[saprotrophic]] (feeding on decaying matter) and [[parasitism|parasitic]] to [[lichen]]-forming organisms, and rare occurrences as [[lichenicolous fungus|lichen dwellers]]. 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]] of these fungi is typically crust-like in form. In cases where a {{lichengloss|photobiont}}, or [[photosynthesis|photosynthetic]] partner, is present, it is usually of the {{lichengloss|chlorococcoid}} type, which consists spherical [[green algae]].<ref name="Frey 2016"/>
The reproductive structures, known as [[ascomata]], have a range from [[apothecia]]l (open, disk-like) to {{lichengloss|perithecial}} (flask-like) forms. They can have various forms, from {{lichengloss|biatorine}}, which are apothecial with a thalline margin, to {{lichengloss|lecideine}}, which lacks a {{lichengloss|thalline}} margin, or even {{lichengloss|zeorine}}. Often, these structures have an inner crystalline layer within their margins. The internal structure of the ascomata features [[paraphyses]] – sterile filaments – that are unbranched and sometimes have swollen ends. These paraphyses are [[amyloid (mycology)|amyloid]]. {{lichengloss|Periphysoids}}, which are hair-like structures, typically line the outer part of the ascomata, known as the {{lichengloss|excipulum}}.<ref name="Frey 2016"/>
The [[ascus|asci]] (spore-producing cells) are thin-walled with a small, apical structure protruding into the internal cavity, known as the {{lichengloss|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]] to filament-like, and are [[hyaline]], meaning they are translucent. They have a variety of segmentations, from crosswise partitions to occasionally being multi-chambered ({{lichengloss|muriform}}), and have thin [[septum|septa]] and walls. There is no known formation of [[conidiomata]], asexual reproductive structures, in this family.<ref name="Frey 2016"/>
