Diatrype virescens
species of fungus

Diatrype virescens is a carbonaceous pyrenomycete in the family Diatrypaceae. It grows uniquely on the wood of American beech (Fagus grandifolia) in North America. Its growth structure is immersed, popping out from under the bark in scattered green fruiting bodies which soon fade to black.
Description
Diatrype virescens grows from under the bark, pushing it aside in a conspicuous manner. The fruiting body is yellowish-green, and ranges 2.5–4 mm in diameter. The color fades into brown and black and soon can look similar to Biscogniauxia marginata. There are usually several sulcate (grooved) ostioles per fruiting body.
Microscopic features are: "Asci clavate, p. sp. 35–40 × 4–6 μm.
Begin with the source’s own compact description: “Diatrype virescens” is species of fungus. The dossier treats that line as a proposition to test through Diatrype, virescens and species, not as a finished interpretation.
Why this record matters
The phrase “species of fungus” 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 date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 1, 2025. The linked authority identifier is Q10470995. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
