Picture Mushroom app review: what it does well, and the alternatives

What Picture Mushroom is

Picture Mushroom is a mushroom identification app sold by Next Vision Limited, part of the same family as the PictureThis plant app. On the App Store it is "Picture Mushroom: Identifier" with the subtitle "Fungus ID, Guide, Finder & Map". It has been on the App Store since 2019 and is the most established mushroom-specific app in the category.

The website's headline is "Discover 5,000+ Mushrooms Species", and it describes the app as an "AI mushroom expert in your pocket" that lets you "identify thousands of mushrooms for free" (picturemushroom.com, 2026-10-31). The App Store description lists a larger figure, "150000+ species", under its Premium features (App Store, 2026-10-31). We cannot say which number is right; the two pages disagree.

Platforms and maintenance. iPhone and iPad on iOS 15 or later, in English plus 17 other languages; the current iOS version is 2.14.0, released 2025-10-29. The Android listing was updated on 2026-09-18 (Google Play, 2026-10-31).

What it does well

Picture Mushroom's strength is breadth. From the App Store description, the app offers:

• photo identification of "numerous species of mushrooms, fungi, and the like";
• toxicity warnings on species pages, sold as "toxicity ID";
• habitat and identification information, plus articles;
• foraging-site tracking, seasonal recommendations and a distribution map;
• an in-app collection of your finds;
• an "Expert Consultation feature", added in version 2.12.0 in November 2023, which the description calls "free consulting with experts" for Premium members.

For someone who forages often and wants a single app with a map, a log and a large encyclopedia, that is a lot in one place. Its photo recognition also scored best of the three apps in the one published test (next section).

Two things we would want to know before relying on it, and could not verify from the store pages: how the app shows its confidence when it is unsure, and whether it lists the dangerous look-alikes for a suggested species with how to tell them apart. If you use the app, check both on your first result.

Pricing, verified 2026-10-31

The app is free to download. The US App Store lists ten in-app purchases, all named "Picture Mushroom Premium" except one:

Source: App Store listing, 2026-10-31. The listing does not say which price is the yearly plan and which are monthly or weekly. The description says "Yearly Premium … 1 year (7 days trial)", and that Premium "includes unlimited mushroom IDs, free consulting with experts". Google Play shows in-app items at "$0.99 - $32.99 per item" (Google Play, 2026-10-31).

What that means in practice:

• "Free" on the website means free to download and try. Unlimited identifications are a Premium feature. Expect a paywall with a trial offer early in the app.
• A free trial converts to a paid subscription unless you cancel. That is standard for app subscriptions, including ours. Before you tap "start trial", read which plan the trial attaches to and when the first charge lands. The App Store description's own subscription terms say that "any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription."
• The price list is hard to read. Ten listings with the same name and no plan length is not a clear paywall. By comparison, Spore AI lists a monthly and a yearly price and Mycoscout lists a weekly and a yearly price, one each.

We are not suggesting anything improper. We are saying: read the trial screen slowly.

What the 2023 study found

The only peer-reviewed comparison of mushroom identification apps we found is Hodgson SE, McKenzie C, May TW and Greene SL, "A comparison of the accuracy of mushroom identification applications using digital photographs", Clinical Toxicology 2023;61(3):166–172 (PubMed, doi 10.1080/15563650.2022.2162917). The authors, at the Victorian Poisons Information Centre and the Royal Botanic Gardens Victoria in Australia, had "observed an increase in poisonings after incorrect identification of poisonous species as edible, using these applications". They tested three apps, Picture Mushroom, Mushroom Identificator and iNaturalist, with photographs of 78 specimens sent to the center over 2020–2021, each identification confirmed by an expert mycologist, and each app tested independently by three researchers.

The results for Picture Mushroom, quoted from the abstract:

"Picture Mushroom was the most accurate of the three apps and correctly identified 49% (95% CI [0-100]) of specimens, compared with Mushroom Identificator (35% [15-56]) and iNaturalist (35% [0-76]). Picture Mushroom correctly identified 44% of poisonous mushrooms [0-95], compared with Mushroom Identificator (30% [1-58]) and iNaturalist (40% [0-84])."

On the death cap specifically, "Mushroom Identificator identified more specimens of Amanita phalloides correctly (67%), compared to Picture Mushroom (60%) and iNaturalist (27%)", and the death cap "was falsely identified, twice by Picture Mushroom and once by iNaturalist". The conclusion:

"Mushroom identification applications may be useful future tools to assist clinical toxicologists and the general public in the accurate identification of mushrooms species but, at present, are not reliable enough to exclude exposure to potentially poisonous mushrooms when used alone."

How to read this fairly:

• Picture Mushroom came first. 49% overall and 44% on poisonous species was the best of the three, and 60% on death caps was second best.
• "Best" still meant roughly one in two. On poisonous specimens, the app was wrong more often than it was right.
• The app versions were from 2020–2021. Picture Mushroom has shipped many updates since. We found no newer published test, so nobody can say how the current version would score.
• The confidence intervals are very wide (0–100% for the headline figure). The sample was small. Treat the direction as solid and the exact numbers as rough.
• Mycoscout was not tested. It did not exist then. We make no claim that it would do better; we quote this study because it is the reason every app should show its uncertainty and send you to a second check. See are mushroom identification apps accurate? for the full picture.

How Mycoscout differs

Picture Mushroom is built around an encyclopedia: a big species list, maps, a log, articles. Mycoscout is built around one question, "is this dangerous?", and the result screen is arranged in that order. The differences we can state from our own app, not from a test:

• Verdict first. The edibility verdict is a full-width band at the top of every result, in a fixed color for each level. Edible verdicts always read "Edible — verify before eating". The app never says "safe to eat".
• Confidence shown. Every match carries a LIKELY, PROBABLE or UNCERTAIN badge. When the app is unsure, it says so and lists other possibilities with their own verdicts, so a poisonous candidate is never hidden behind an edible top match.
• Look-alikes named every time. Each result lists the dangerous look-alikes with a "tell apart" line and a "risk" line, plus a checklist of features to confirm yourself. Our look-alike pages follow the same pattern, for example chanterelle vs jack-o'-lantern.
• Guided capture. Four angles, cap, gills, stem including the base, habitat, each with the reason it matters. Blurry or dark photos are flagged on the device before they are used.
• Clear pricing. 3 free identifications, then Mycoscout Pro at $29.99 per year with a 7-day free trial, or $3.99 per week, US prices (App Store, 2026-10-31). Two plans, one price each.

What Mycoscout does not have, and Picture Mushroom does: a distribution map, foraging-site tracking, a species encyclopedia to browse, articles, and an expert consultation feature. Mycoscout needs an internet connection and has no offline mode. It was first released on 2026-09-24 and has no published accuracy test. It is a field companion, not a mycologist, and a result is never a clearance to eat.

Free alternatives

If what you want is a second opinion rather than a subscription, these cost nothing:

• iNaturalist is "free, nonprofit, community-powered". The app suggests an identification, then "a global community of naturalists confirms or refines it". An observation reaches "Research Grade" when "more than 2/3 of identifiers agree on a taxon at species-level" (iNaturalist help). It gives no edibility verdict, and a person may take hours or days to answer, but a human who knows the genus is the best free check there is. In the 2023 study it scored 35% overall and 40% on poisonous species, with only 27% on death caps, so its AI suggestion alone is no better than the paid apps; the value is the people.
• Seek by iNaturalist is free, needs no account, and "does not collect any user data by default". Its 2020 user guide says the identification "does not leave your device or require an internet connection" and that the camera "does not know everything, so it may be wrong" (Seek user guide). It stops at genus or family when unsure. No edibility information.
• Google Lens gives you a name to search in seconds. We found no published test of its accuracy on mushrooms (search on 2026-10-31), so we cannot rate it. It shows no verdict, no confidence and no look-alikes.
• A local mushroom club. In the US, the North American Mycological Association lists affiliated clubs by state. In the UK, the British Mycological Society lists local fungus groups. A person holding the whole mushroom, with the base dug out and a spore print on the table, beats any photo.

The bottom line

Picture Mushroom is a mature, feature-rich app with the widest encyclopedia and the best score in the one published test. That score was 49%, with 44% on poisonous species, and the study's authors said that is not enough to rule out a poisonous mushroom. Its pricing is harder to read than it should be; read the trial screen before you start one.

If you want breadth, maps and a log, it is a reasonable choice. If you want a result that leads with the verdict, admits when it is unsure and names the look-alikes, that is what Mycoscout is for. Either way, take better photos, post the find to iNaturalist, learn the features a photo cannot show in how to tell if a mushroom is poisonous, and never eat on the strength of an app.
