Laetiporus on Poplar

[Gary Prentice]

In passing yesterday I saw some brackets, that due to colour and shape, I took to be Laetiporus. I did get a photo but the day was so dismal it isn't even worth posting.

 

I know it's an annual FFB, but these looked quite recent/fresh, so I've got to wondering what actually triggers the fruiting? Length of daylight hours, average temperatures or what.

 

As I think it's a highway tree, I've emailed the TO, so he'll probably come along and educate me that it's not what I thought it was and I'm just ignorant:confused1:

 

Anyway I'm just puzzled because of the time of year to see anything that appears to be actively growing.

Show us the picture Gary, visual context will help.

Looking at the photo, the tree is more likely to be oak:blushing: I was turning around at the end of a cul-de-sac with a couple of cars behind me. Took the picture out of the car window as I was turning - that's my story and I'm sticking to it:biggrin:

Had a little play with image as I wondered if they had gills at all, but they look pored so Laetiporus looks a fair shout.

 

Also had a quick look through the 3361 records for Laetiporus in the UK and there's a record for pretty much every single month of the year.

 

Example of a January record........

 

Laetiporus sulphureus, on/with Quercus, dead stump, woodland, 02/01/2015, England, Cheshire (VC: 59), Hale: Icehouse Plantation, SJ4681, coll.: A.E. Carter, id: A.E. Carter, FRDBI Record No.: 2044289, Origin of Record: North West Fungus Group (John Taylor) full data record

 

Ofcourse the above doesn't say what state the fruitbody was in at the time the collection was made but.

 

Don't think I've come across it fruiting this time of year before.

 

Temperature is a key factor, though some species thrive during the winter months, such as Flammulina and Pleurotus

Okay, you've peeked my interest. I'll get back and harvest a sample in the next few days. Apart from a few snowy days, we've not had more than a couple of mornings that have been sub-zero

I may have a partial answer to the triggering mechanism, but you'll have to wait as it requires a lot of typing and I am having to leave on survey for a couple of days.

[Gary Prentice]

No rush Jules.

 

 

But to expand the question I wonder if the triggering is common among basi's and asco's, annual and perennial ffb's and white/brown rotters?

Acht, I have just moved office and I can't find a thing. It may be a day or two before the reference book I need comes to the surface.

No worries at all, Jules, I'm sure that you've enough to do at the moment.

 

Been back to the tree and managed to harvest a bracket or two. They've lost a lot of colour over the last week, so fairly confident that they're oysters. Pleurotus ostreatus - or rather Mattmoss is:biggrin:

 

I'm disappointed now, cos I thought I'd found something fruiting at an unusual time of year.
