This week’s blog was written by guest blogger Dustin H. Purcell, MS. Dustin is a Mycologist/Plant Pathologist who studied at the University of Florida.
This is a true fungus (just like other mushrooms, toadstools and puffballs) named Pisolithus tinctorius, and apparently a nice purple to coppery golden brown fabric dye can be made from them, though I confess to have never tye-dyed with this shroom. Like the “dog vomit fungus” discussed in an earlier blog post, it looks like something that might have been left behind by a dog. In more polite company, you might say it looks like a stalked puffball sculpted from chocolate. They range in height from 2 to 6 inches and terminate in a bulbous knob from 1 to 3 inches in diameter. Initially they are covered by a smooth firm skin, but this weathers away to expose and liberate the cocoa-powder-looking spores inside.

Both of these pictures are of the same Pisolithus mushroom. The one on the left is only slightly weathered and the cinnamon colored spores can be seen. In the photo on the right, taken 2 weeks later, all of the spores have been washed away by a heavy rain.

This fungus is mycorrhizal, meaning that the portion below the ground (which happens to be significantly more than the portion you see above the ground) forms mutually beneficial relationships with trees… The faux-latin word mycorrhizae is formed from the latin words for fungus and root. The below ground portion grows through the soil as microscopic strands which decay organic matter (like rotting leaves), absorb nutrients and water, and wrap around the roots of trees (especially pines and oaks). Though these odd mushrooms may be many yards from the trees with which they form mycorrhizae, rest assured that they are in partnership with at least one of the trees nearby. The fungus exchanges nutrients and water with the trees, allowing the plants to grow well under harsh conditions. They are credited with helping trees survive drought conditions and for this reason are important to forestry. They can be seen sporadically throughout the year in Florida anywhere trees grow, especially on dry sandy soil. They are not uncommon to see around oak trees planted in parking lots and median strips where they undoubtedly aid the trees in these stressful environments.
They are not known to be harmful to people or animals and are helpful to trees in the landscape. For these reasons, try to appreciate their ecological importance rather than being put off by their gross appearance.

A very good guide to beginning gardeners and arborists. One thing I can't stress enough when teaching about gardening is your placement. Look for whats above, behind, below, and what it could grow to block or overcome. Happy Gardening!

Recycling helps the earth because it could save animals, it could save birds, puppies and all kinds of them. A lot of the animals that recycling helps to save are the ocean animals. There are a lot of animals in the ocean that mistake trash for food. They're eating things that we could be recycling. Check out this video: http://youtu.be/-H51E2gwXwc

Have you read Teaming with Microbes? Good book that is doing a lot to help me understand the good side of fungus and all the other tiny stuff in the soil. Who knew?

I saw several nymphs this season for the first time ever. They are some of the more bizarre bugs to have in the garden, but I hope they'll have a good effect!

We have the dog vomit slime mold for the first time in our yard as of this spring.
Thank you for this post, it is reassuring to see that what we are doing (organics ONLY) are making a difference!

Thanks Theresa, there was a host of the Slender Flattop Goldenrod, Euthamia Caroliniana, last Oct. in an open field now just knowing this species, and what I think is the Late flowering Thoroughwort, Eupatorium serotinum nearby in semishade making the bees crazy.

We have ongoing problems w/ this @ the city park where I work - I've tried rinsing the affected skin w/ hot water, which seems to help. I understand that cooking neutralizes the sting (people actually make tea from & even eat stinging nettle).

This is not the first of your posts I've read, and you never cease to amaze me.Thank you, and I look forward to reading more.

What a cool looking mushroom. I think I will take the writer's advice and avoid walking in the dark woods to find it though.

I love both the beauty berry and firebush together. Always have flowers or berries, bright colors, drought tolerant to a degree... Nice plants!

You are welcome Becky- hopefully you don't find it!

I really like the pic of winter flowers. Your article is very well written cant wait to read more. Interesting Blog I really liked it.

Has there been any discussion as to why the population explosion of the spanworms occurred this year? Was it related to the very dry winter and spring (eliminating many wasps) followed by heavy rains which spurred the snowbush's growth?

Great links! Thanks for sharing!

Great tips. I recommend that all DIYers mow tall in summer just to avoid additional pressure on struggling turf.
Organic fertilizers work well in summer to avoid excessive growth, as long as they have plenty of time to break down prior to those heavy storms you mention.
July 21, 2009
That was an important point you made about fertilizer use during this rainy time. Suggest all use slow-release fertilizers to avoid excess run-off of nitrogen & phosphorus into our waterways.

Pam,
Thanks for such great details. For the 37th Edition of the Festival of the Trees blog carnival, we talked about Survivor Trees. Your post was a fitting addition to the "Hurricane" section!

I got to this page from reading your article about laurel oaks. I would love to chat with you about a problem that I am having with one of the oaks on my property- either by phone, or email. If you could oblige me, I'll send you my email address.
Now, back to reading about these orchids!

I am fully behind the termination of Sevin use for anything that might come in contact with any beneficial life forms.

I hope that this will be lots of fun!

Anyone know where I can get some good rain barrels? Not the plastic kind. I live here locally. Thanks! Kelli

I briefly read this early this month and discarded it, but while in downtown ST Augustine I saw a palm with symptoms that could be a diseased palm. This was the other day in the plaza (used to be called the slave market). That would be a big jump from Manatee / Hillsborough County, but other palms around this specimen in the area are healthy and it has been in the ground for some time. It probibly is anouther disease or deficiency. I have been in the nursery/ landscape business for 30 years and hate to see the infections that are effecting our major trees, citrus, bays, palms, next? Craig Hartwig.
