Pleurotus dryinus
species of fungus
Pleurotus dryinus, commonly known as the veiled oyster mushroom, is a species of fungus in the family Pleurotaceae. It grows on dead wood and is a weak pathogen, especially infecting broad-leaved trees.
Taxonomy
The original definition of this fungus as Agaricus dryinus was made by Christian Hendrik Persoon in 1800. In 1871, Paul Kummer introduced Pleurotus as a genus and defined three similar ringed species: Pleurotus corticatus, Pleurotus albertini and P. dryinus. They were distinguished because only P. corticatus has intertwined ("anastomosing") gills on the stem and P. albertini is bigger and grows on conifer wood rather than oak. All three are now considered to be forms of the same species. The name dryinus takes precedence because it is the oldest.
Also, in 1874 Elias Magnus Fries defined a species as Pleurotus tephrotrichus, which has a deeper grey colour. This has also been incorporated into P. dryinus but may be distinguished as the variety tephrotrichus.
Etymology
The species name is a Latinised version of the Greek word "dryinos" (δρύῐνος), meaning "related to oak", referring to one of its main hosts.

Why this record matters
“Pleurotus dryinus” is worth following because a concise public description often conceals a longer documentary argument. Here, Pleurotus, dryinus and species provides the most credible route into that argument.
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 Jun 30, 2026. The linked authority identifier is Q820657. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1800, 1871 and 1874.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
