Our trip through Chile brought us to Valdivia, where we found a variety of odd balls.
Some, like Tetrapyrgos alba, this very delicate, almost lacey basidiomycete, for instance, showed up frequently on small decomposing sticks. This beautiful white mushroom was a photo favorite for anyone who ran across it.
But others hid in deeper obscurity, like the Xylaria colony below, and its accompaniment of resting spiders
Xylaria hypoxylon and possibly a second Xylaria species looking for all the world like miniatures from the set of the Lord of the Rings.
Sometimes the best place to look for mushrooms is the underside of a log, and this was no exception. In fact, there's a lot going on in this picture fungally. The black fronds are one Xylaria species, while the light frond in the nearer foreground is Xylaria hypoxylon. Meanwhile, the spiders, locked in a kind of "oh shit" rigor mortis, seem to be resting on a bed of resupinate fungus themselves.
The wildlife on this log's underside was not limited to spiders and mushrooms
Compare this fella to Limax maximus and the resemblance is not insignificant.
Whatever the exact species of this prodigious slug, he made for a strange bedfellow in this well-defined underworld. You can make out the mottled texture of his skin, as well as the hints of the many spires of Xylaria blurred in the background.
The finds in Valdivia were not all hidden away and obscure. Some made themselves known from a surprising distance, and by surprising means.
Cortinarius lebre - one of the few Cortinarius we found that can be identified without too much question.
This little species is quite beautiful IMO, a very delicate shade of purple or lilac, with slightly glistening, slightly sticky cap and obviously a cortina, this phallic little number tends to stand out visually.
But its real superpower is scent!
You don't need to cut C.lebre open in order to get a whiff of its extraordinarily powerful odor.
But it helps. Even as you approach the mushroom you begin to smell an intense chemical scent. To me, it smelled like something akin to a crushed up pencil eraser.
Once you cut it open and lean in for a sniff the odor hits your olfactory senses like smelling salts. It it intensely odoriferous, and not a pleasant odor either. If the unbroken mushroom smells sort of like a pencil eraser, the sliced mushroom smells like being on the floor of a pencil eraser factory. Just a nostril filling smell that drags itself all the way through your sinuses and deposits itself onto the back of your tongue.
The cut specimen was impossible not to smell, and once you knew what it smelled like, it was totally possible to find and even identify the presence of this mushroom, through smell alone.
Get done looking at the well defined photos of the partial veil and pretty underlying gills and then check out the other end of the Cortinarius spectrum below.
Just to highlight the wide variety and complexity of the Cortinarius genus, here's another.
This cute species could not look more different from C.lebre, and yet it is in the same genus. This species was visually a bit remarkable for the slight greenish tint of its tightly packed and elegant looking gills. But I have no idea what species it is, as is the case for many of the Cortinarius we found.
Non-Cortinarius species tended to provide more hints.
Russula aff sardonia for instance - found in the same pine forest where we discovered that boat load of Amanitas.
"Aff" in this case stands for affinity, meaning this is a Russula with, at least, an affinity or significant resemblance to a species known as sardonia. Along with the three giant Amanita species, this Russula was the fourth fungus growing in unbelievable quantities in that pine forest off the road on the way back from the park.
I was asked - as a form of jovial hazing - to take a small nibble of these fellas to confirm their acrid taste - which was fairly extreme. Often that is the case for Russula species.
Whereas these Russulas were the height of my forearm some of them, other species thrived on an altogether different scale.
We only encountered one Leotia species, a stalked jelly mushroom.
The exact species in this case is not clear, but for general comaparisons sake you can compare to Leotia lubrica, which you can find all over the world.
Leotia mushrooms are not basidiomycetes by instead ascomycetes, meaning the spores are held in microscopic tubes or asci and then protruded out when mature.
It takes only a cursory glance up close to see how these mushrooms are different from most fleshy fungi with stipes.
There is no gill structure in a Leotia species. Instead, the fertile spore surface is the jelly like cap, revealed here with a crude cross section.
Generally, you see this kind of jelly capped ascomycete growing direct off wood and stalkless. However, Leotia bucks that trend, taking a different, stalked, evolutionary route.
Last but not least
A gorgeous Chlorophyllum species.
Look at those beautiful parasol like mushrooms are just stunning I think. They were placed in the Chlorophyllum genus by one of my travel companions, although I can't say for certain that they aren't Macrolepiota for instance.
But whatever they are, boy are they pretty. The scaled cap with the gorgeous veil remnants along the edge. The movable ring on the stem, free white gills, a robust stalk, high off the ground. These mushrooms are always a pleasure to find, like stumbling across a forest pixie.
Our time in Valdivia was well spent. After this we moved on toward super beautiful Pucón, where we got to explore the most beautiful deciduous forest hidden on a large farming estate, packed to the proverbial gills with beautiful mushrooms.
