Observation 18444: Descolea antarctica Singer
When: 2009-02-09
No herbarium specimen

Notes: Found these three in some woody mulch; CP 2-3", orange-brown (as shown) fading to buff-tan when dry (defintely hygrophanous), very viscid, striate; GILLS ragged edge, nearly free; STIPE slightly bulbous, pale ner top to cap-colored near base, rather fragile, smooth; VEIL conspicuous, membranous, superior, skirt-like; SPORES golden to ochraceous (clear print visible on top of ring).

Proposed Names

28% (1)
Recognized by sight: brown viscid cap, skirted persistent ring, brown spores.
60% (3)
Eyes3
Recognized by sight: The most common species of these in Chilean Nothofagus forests (whatever that is…).

call D. antarctica “dark brown when moist, becoming ochreaceous with drying,” and there is a noticeable drabness in their image of that sp. as compared to both of yours (this one and Observation 18921). I think there are other Descolea reported/described from the area, but the literature is not readily available. Possibly D. pallida and D. recedens. Then again, maybe cap color is variable…

I bet this impossible to find text:

would help.

very interesting discussion!

and love the potential sp. designation of D. antarctica…not many mushrooms hailing from THAT neck of the woods!

I am perplexed as to just how your method would work, Dan, since my experience w/dessicant has been that as it pulls moisture from the air (or shrooms) it leaves a layer of water on top of the beads.

And speaking of Pringle cans as great myco-storage units…check out this slightly modified one that I sent to Anne Pringle (no relation) with a phalloides specimen that had been collected under an unusual pine host here in CA. I would link it to the BAMS list photo section, but not everyone could get access.
So sorry, Nathan, for this marginally mushroom posting!

desiccant drying

Hi Jason,

Fresh mushrooms can be placed in between layers of desiccant in a sealed plastic container to dry them. This tek works even in jungle humidity. Put down an inch or so of desiccant, a tissue, the mushrooms, another tissue, and then top off with another layer of desiccant.

I’ve only tried it with Drierite purchased from Mycosupply:

I think Damprid would probably work just as well. Of course this tek works better for small dryish mushrooms than for large juicy ones.

Nothofagus = southern beech/oak

Down here Nothofagus forms the basis of both deciduous and evergreen forests from sealevel to subalpine. They replace both pines and oaks, for example, in northern California-like climates in Chile. They are quite beautiful and (obviously!) versatile trees. Their lineage traces back to the Gondwana era (before 150 m.y.a), and thus are important throughout the temperate southern hemisphere, including New Zealand and, to a lesser extent, Tasmania (where gums have taken over dominance in all but the wettest areas).

Thanks guys!

Actually, Debbie, I’d be interested in learning Terry’s technique. It might be too late to acquire necessary materials for this particular trip, but for the future… Space was a distinct problem on a long hike like the Torres del Paine Circuit, true, but I have still managed to collect several boxes of lichens throughout this trip. But every time I try to include fungi (esp. ascos which I confess interest me more) they disintegrate before I arrive “home” to pack them properly in tissue in pringles cans. :(

Might be Descolea

It looks like Descolea is your best bet here, this is a southern cousin of Conocybe/Pholiotina, with the cap structure of Conocybe, but the spores are like Galerina. It looks like this is a common genus in the southern hemisphere, but rare in the northern (very rare). There was some found in Hawaii, and they might have come with Eucalyptus from Australia. There does seem to be one report of this genus from Europe, but it sites itself as the only one.

There seem to be lots of species in the genus, but one site claims that Descolea antarctica is the most common in Chile.

never say never, Jason…

I believe Terry Henkel has developed a method for drying mushroom speciemns in the rain forest of Guyana using water sucking beads (similar to DryZ Air, which I use to keep my herbarium specimens dry during storage). I don’t think that there is electricity where he does his field work, and I’m sure that he’d share his technique for future trips! Unless it’s the transporting stuff around that is the problem…

I know, it kills me…

But there’s just no way to collect and preserve any fleshy fungi I see on this trip. Still, I hope it’s edifying to at least see some photos to get a feel for what sort of stuff is down here…

These guys are cute…

These guys are fairly cute, too bad you don’t have any microscopic features on these. Almost anything would help put these somewhere…
