a wet mushroom in a tackle box?

to my very limited understanding — made only slightly less limited by briefly skimming through these two articles1 2 — deliquescence refers to a specific process of timed autodigestion accomplished via certain hydrolytic enzymes, chitinases to be specific. the question is whether or not the coprinoid fungi do this in such a way as to have a monopoly on the word ‘deliquescence.’

It is noteworthy that deliquescent fruiting bodies also occur outside the Psathyrellaceae in the families Agaricaceae and Bolbitiaceae , although it has been suggested that the autodigestive phase is physiologically somewhat different in these families (Hallen et al. 2003).2

So the coprinoid fungi don’t have exclusive rights to the term ‘deliquesce’ (instead there’s ‘coprinoidization,’ taken from the same paper), but there are these physiological differences in autodigestion methods between the coprinoids and outlying deliquescent fungi.

the paper quoted above is free. the work cited at the end of that quote, however, (Hallen et al. 2003) is not as readily available. that’s where the rabbit hole appears to go from here…

in any case, according to at least one paper, use of ‘deliquescence’ is fair game outside of the traditional coprinoids. that said, we may know this enzymatic process when we see it, but only because we can identify the species or genus in question, and refer back to the conventional wisdom that tells us “this is how and why this fungus turns to a black puddle.” other goopy fruiting bodies are not necessarily goopy as a result of the same, highly specialized, enzymatic chain reaction.

fancy that. a question that leads to more questions. this must be a mushroom forum.

What would you call this?


If there is a better word then deliquescing, then I would love to know it.

lacking any yellow, some rather coprinoid light brown flecks in primordia, and deliquescing to such an extent that entire pilei are missing from withered, capless stipes.

What Bolbitius does (sometimes) I wouldn’t call deliquescence, any more than the putrefaction of any other non-coprinoid fleshy fungus, even if it gets “melty” in the process.

Some small Bolbitius species do kind of melt, but more like a Gastrocybe then Coprinoid. From Mushrooms Demystified “…is reminiscent of Coprinus (particularly the striate cap and tendency of the gills to liquefy somewhat)…”
An example would be obs 70959 which left me a mushroom shaped bubble when I tried to spore print it and maybe obs 73806 (W/e that is).

However, these appear dark spored, so I would agree with you that they are not Bolbitius.

Coprinopsis or Coprinellus. EC will have more to offer.

This small mushroom is very delicated an gelatinous.
