How to Document a Wild Find for Expert Verification

Document a wild find by photographing it in place from several angles before you touch it, collecting the whole specimen intact rather than a piece of it, and writing down substrate, habitat, date and location. Then take that record, and the specimen, to a qualified local expert in person — verification does not happen over a photograph.

Why a phone photo is never enough

The single most common request experts receive is a blurry picture of something held in a hand, with no substrate, no scale, no habitat, and no location. There is nothing to work with. Whole categories of features that matter are simply not present in that image, and the ones that are present may be distorted by the light or the angle.

Good documentation is not a better hero shot. It is capturing enough surrounding evidence that somebody who was not there can reason about it, then handing over the specimen so they can examine what no camera records.

Photograph it before you disturb it

Shoot first, collect second. Anything you learn from the undisturbed find is unrecoverable once it is in your bag.

Shoot in even natural light rather than direct sun or a phone flash, which wash out the colours you were trying to record. Take more frames than you think you need.

Collect the whole thing, and keep it separate

Take the entire specimen, including the base, by digging around it rather than snapping it off. A trimmed or broken sample is missing evidence, and the missing part is often the part an expert wants first.

• Collect several individuals at different stages if they are present, since young and mature forms can look very different.
• Keep each collection in its own container, wrapped in wax paper or a paper bag, never loose together and never sealed in plastic, which makes specimens sweat and degrade.
• Label each container in the field with the date and the spot, not from memory afterwards.
• Never mix an unverified collection with anything else you have gathered.
• Keep collections cool and get them looked at quickly; most degrade within a day or two.

The written details a photo cannot carry

Write these down while you are still standing there. Together they are often worth more than the pictures.

• Date and time, and the location, at least to the level of the site and terrain.
• What it was growing on or from, and whether that wood was living or dead.
• The nearby trees and ground cover, plus slope, aspect and how wet the ground was.
• How it was arranged: single, scattered, clustered, in a line, in a ring.
• Approximate measurements, and texture as felt rather than as it looks.
• Any change you observed over minutes, and whether there was a distinct smell.
• Recent weather, particularly rain in the preceding days.

For fungi, a spore print made at home overnight is standard documentation to bring along; it records a characteristic photographs cannot. Treat it as one more observation for the expert, not a conclusion of your own.

Who to ask

Look for a local mycological or botanical society, a university herbarium or extension office, a museum or botanic garden, or a naturalist group that runs identification sessions. Regional field guides written for your area are the reference to check against; a guide for a different continent will lead you astray. Online forums can be a useful sounding board, but a comment from a stranger who has never handled the specimen is not a verification.

What a verification settles, and what it does not

An expert examining your specimen in person can tell you what it appears to be. That is a determination about identity. It is a separate question from whether anything is safe for you to eat, which depends on the specific specimen, its condition, where it grew, how it is prepared, and your own health — and which no photograph, app or checklist can answer.

Record the outcome either way, including who verified it and when. An unresolved entry is still worth keeping — next season you will find something similar, and the old record is where you start.
