Sterile fungi
form group of fungi that do not produce any spores
The sterile fungi, or mycelia sterilia, are a group of fungi that do not produce any known spores, either sexual or asexual. This is considered a form group, not a taxonomic division, and is used as a matter of convenience only, as various isolates within such morphotypes could include distantly related taxa or different morphotypes of the same species, leading to incorrect identifications. Because these fungi do not produce spores, it is impossible to use traditional methods of morphological comparison to classify them. However, molecular techniques can be applied to determine their evolutionary history, with ITS testing being the preferred method. Several lichen genera include sterile species: Andreiomyces, Aspicilia Buellia, Calvatimella, Chrysothrix, Lepraria, Megalaria and Phlyctis. According to one study, approximately 42% of fluids collected from broncho-alveolar lavage have had sterile mycelium observed in them.
Begin with the source’s own compact description: “Sterile fungi” is form group of fungi that do not produce any spores. The dossier treats that line as a proposition to test through Sterile, fungi and form, not as a finished interpretation.
Why this record matters
The phrase “form group of fungi that do not produce any spores” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q7611335. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
