Sagiolechiaceae
family of fungi
Sagiolechiaceae is a small family of lichen-forming fungi in the order Ostropales. It contains two genera, Rhexophiale, and Sagiolechia, the type genus.
Some Sagiolechiaceae species form crustose lichens with Trentepohlia-like photobiont partners (a genus of green algae); other do not form a thallus and are lichenicolous (i.e., they grow on other lichens). Asci are eight-spored with colourless ascospores that have transverse septa or are muriform (i.e. divided into chambers by both transverse and longitudinal septa). The genera Sagiolechia and Rhexophiale mainly differ from each other in how their fruiting bodies develop.
Taxonomy
The family was circumscribed in 2010 by the lichenologists Elisabeth Baloch, Robert Lücking, H. Thorsten Lumbsch, and Mats Wedin. Molecular phylogenetics analysis showed that the two genera formed a distinct clade in Ostropales. Four species were included in the original circumscription of the family.
Description
Members of the Sagiolechiaceae typically form crust-like (crustose) thalli, often containing green algae of the genus Trentepohlia as their photosynthetic partners.
This brief starts where responsible research should: with the source description of “Sagiolechiaceae” as family of fungi. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as family of fungi. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q20668247. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
