Summer Mushroom Adventures

It seems that once people know you are interested in mycology, they take an interest in sharing their finds with you. This has provided some interesting experiences in the last few weeks.

First, a Giant Puffball walked in the front door, in the hands of a little boy who had been in the Primary class I had substituted for a few Sundays previous. A mushroom that has been requested by my customers, so I was very pleased to receive it! It was set to cure in the basement, where it emitted an unpleasant odor for about a week before it finally stopped stinking. But it is curing well, so it was worth the smell.

Next, some Aspen Boletes made their way here, along with some lovely mature King Boletes. Easy to tell them apart – the Aspens bruise dark, and the spore tubes go dark gray with age, whereas the Kings do not bruise, and the tubes turn an olive green shade. Both were riddled with maggots, which is not a problem since they drop out as soon as we start to dry the mushrooms. Disappointing to me though, because the maggots drop out onto the drying trays (we have screens, over trays, so there is a catch pan under each screen), and we have no chickens right now to enjoy the benefits of those maggoty mushrooms!

Some Aspen Oysters wandered in one day, and were promptly set to dry for spawn, and some were used to sow a box of aspen shavings so we can grow more. Oyster mushrooms are easy to grow, and Aspen Oysters have the distinction of being able to grow on Alder.

A few days ago I was given two mushrooms that were old and degraded. They appeared to be a polypore of some kind – not that there was any spore surface left, but I’d seen a polypore before that had degraded in the same way, with the same kind of pattern on the underside when the spore surface had been eaten away by bugs. They were waterlogged, soggy, and maggoty (more so than the boletes). The stems were falling off, and the caps were hardly holding together. I chose NOT to bring them into the house!

The lady who gave them to me said as an afterthought, “They were growing from the same stem.”. I promptly forgot that she said that.

Later, when trying to ID them, I could see the texture and color of the caps, and combined with my assumption of a polypore was a good start. But I could not get an ID for anything, there are just too many stemmed polypores of similar color.

Finally went back outside to look at them again, and paid attention to the stems. I could see where they had broken apart, and they had a common base… and a ROOT! They had a sturdy black root that descended from one of the stems, that I had not noticed before.

I knew that was the identifying feature, because roots like that on mushrooms are uncommon. Turns out that there is only one rooted polypore, and it is known by that name.

If I had not had the stems, and had not seen that root, I could not have ID’d that mushroom. Having the root made the ID EASY because there is nothing else like it – orange cap, and black root, confirmed the polypore ID.

When you receive mushrooms from other people, they may or may not have the entire stem intact. It is always more helpful for identifying if you have the entire mushroom with the stem base, and a description of the habitat where it was growing, because those things can help to confirm an ID, and in some cases, they can be the ONLY clue to a certain ID.

A lot of people have been sending me photos of mushrooms to ID. 9 out of 10 of those images are Little Brown Mushrooms, and an ID is fairly hopeless. I generally only bother with edibles, if they are not edible, or medicinal in some cases, I could care less what they are called.

There is a rule about edible mushrooms. Generally they are the more substantial mushrooms. There are a few LBMs (Little Brown Mushrooms), or LWMs (Little White Mushrooms), or LGMs (Little Gray Mushrooms) which are edible and grow in troops, but overall, the good edibles will be large, and have distinctive features. The smaller ones are too difficult to differentiate, there are just too many like them, and they are generally not worth identifying anyway, since they would take too many to be worth the effort to pick. Consequently, many have never been identified, and most mushroom hunters ignore them because they are too tricky to get right, and not worth the bother anyway.

Today I felt impressed to go to an abandoned chicken coop that is on the property we are renting. It has rained daily for the last several days, so today was a good day to look for mushrooms. But I had not thought to look in there before – the roof leaks, and it has a good layer of old rotted sawdust and chicken manure in it. It occurred to me that something might come up in there because of the rains.

As soon as I came inside the door, I laughed. There was a mushroom, about 3″ across, right in the middle of the floor! Not just any mushroom…. Agaricus Bisporus. Brown Bisporus.

A few old nearly dried mushrooms lurked in the corners, and some new buttons peeked up here and there. Clearly the composting litter was well colonized with Agaricus Bisporus mycellium.

The MOST COMMON commercial mushroom. Nothing special. Nothing exotic.

But this is a fine thing for me, because I was unable to find a strain of Agaricus Bisporus with which I felt satisfied, because it has mostly been crossed with Agaricus Brunnescens, and the distinction has been lost with many commercial strains. I have a really excellent strain of true Brunnescens, but my strain of Bisporus was not as good as I wanted. This new find is a BETTER strain – it has the distinctive differences that set it apart from Brunnescens (slightly thinner cap, less reddening when cut or bruised, and gills that are less pink and turn brown sooner in the maturation process). So now I have a new strain of Bisporus… which I have named “Chicken Run”. What would otherwise be no big deal has been a delightful find for me!

The same people who gave me the old rotting mushroom to ID also gave me another unidentified mushroom which keys out as Albatrellus. I have been wanting a specimen of one of the edible Albatrellus species for many months, ever since I found an old, soggy, and stinky specimen in the woods one day. Completely inedible due to its age and condition, not even usable as spawn, but identifiable due to the stem position and  the fact that it is a large stemmed polypore and there are not many of those. So receiving an Albatrellus specimen was a real gift.

I am unsure of the species exactly – the genus of Albatrellus is certain, but there are a dozen or so species within the genus, many very alike. I only know it is edible because the family that gave it to us have been eating it. Narrows it to Ovinus, Confluens, or Citrinus (based on other features, but they are VERY similar). Started a box of it today, to see if I can get it to grow. I am going to have to find a way to purchase a microscope to be certain of the species though.

It has been a lot of fun having mushrooms walk in the door. I never know what is coming in next. The most amazing thing has been the number of mushrooms that I have on my “needed specimens” list that have been either handed to me personally, or shipped to me from somewhere in the US. Often the person sending them isn’t sure what they are, other times they know for certain. But in both cases, I have been brought some really amazing finds, which have added to our inventory, and are blessing our lives, and the lives of our customers.

I’ve been drawing mushroom images for our website, for the mushrooms that I do not have pics for. Some of them turned out well. Worth a look if that kind of thing interests you, they are on our Mushroom Store website – just click the link on the left for Mushrooms that can be grown indoors, and the other links below that one.
