So to elaborate on the title, if I find multiple mushrooms of the same species in a very close proximity to each other, or fairly close, say within less than 1-2ft of each other, should I take multiple photos of the species and then upload all photos as one observation, or should I/can I separate each by the single fruiting body?
When observing fungi or any other organism, itâs possible to err in terms of being too inclusive (the more individuals depicted in a single observation, the greater the risk of accidentally including multiple similar-looking species), but it isnât possible to err in terms of being too exclusive (e.g. one individual per observation). So if in doubt, itâs better to separate individuals into separate observations.
As a rule of thumb with mushrooms, Iâve been taught that anything within ~2 m (~6 ft) that appears to be the same species is probably the same individual and I would upload them as a single observation. Beyond that distance the risk of multiple species goes up and itâs probably better to create separate observations.
An iNat obeservation is supposed to include âan individualâ. Pragmatic definitions of a âfunctional individualâ for fungi were introduced for fungal conservation status evaluation doi:10.1016/j.funeco.2010.11.001
They say, âFor terrestrial fungi, one may conservatively assume that sporocarps separated by 10m or more represent a functional individual or separate genotype.â
For lignicolous fungi the pragmatic unit is different.
Check previous threads, if thereâs a couple of metres between each fruiting body, itâs one organism, if, say, 50 metres, it can be or can be not the same organism, you canât prove it, so post separately.
@anonymousâs advice seems sound. Use your best judgement - fungi like to break just about every âstandardâ biological concept out there.
Agree with @anonymous. Canât be too careful, especially if the observer isnât an expert and isnât 100% that the two species are different. I generally lump multiple fruiting bodies into one obv if theyâre, say, within 6 feet of one another and I am certain they are the same species.
Thanks for your reply and everyoneâs above. All make perfect sense and good points.
