Ganoderma resinaceum or Inonotus dryadeus

[stevelucocq]

Just interested in some feedback. I have watched this fungus develop on this turkey oak over this year. It started off with all the signs of Inonotus dryadeus with a pinky and flesh like lump forming with goldern droplets on the flesh. Now the brackets are looking more like Ganoderma resinaceum with plenty of rust coloured spores that most Ganoderma brackets produce (is that right?). I have seen this fungus desiccate back to a black mess the year before but not sure if this happens on a yearly bases. I am not sure if G.resinaceum is annual or I think I read somewhere that is may go through a cycle every few years?….any help or ideas would be great as I have changed my mind on this ID a few times already. Thanks steve

resinaceum is quite a rare fungus in this part of the world...prized in china for its medicinal value blah blah...I know where youre goin' with this one in some ways as I might expect it to appear on deciduous trees as per the books....but then they dont always read the books.....There are distinguishing features between the Ganodermas, if you have access to the internet, then it would be worth doing a quick search in google or wikipedia.

Basically, i would say adspersum I think, denoted by the the obvious white margin rather than a slim, fine margin whu, also the slightly uneven volumous shape the bracket has....lumpy undersides...a bit of a giveaway imo....

Either way, it too will result in a soft white rot which affects the roots and lower stem. The result of which is ductile fracture/ windthrow following root fracture and ductile fracture....

Have you attacked it with a lighter???

 

Any chance of a phot of a cross section showing the tubes??

 

I'm sure it's a Ganoderma spp. but looks like it might have a laquered upper surface???

 

Could even be G. pfeifferi???

thanks for the reply...things that were making think that it could be these types of fungi were that it seems to be annual and that the starting form of the fungi looked like every picture i have seen of I.dryadeus. Also the fungi has a crust that cracks when pressed. I have added a few more pics to give better angles of it. You may be right just keen to get a full picture on it.

Well now..thats looks completely different...internet id, why do it? lol

( Jus'thumbing thru' Roger Phillips mushrooms I notice that in earlier editions he called reinaceum pfeifferi )

Well after those pics I'm formally changing my mind back to G. resinacium!!

 

[stevelucocq]

sorry should have put all the pics to start with....yeah i have been reading up on g.pfeifferi and it does state to have a varnish-like resinous layer but is ment to be perennial. This has cropped up over this year but not sure if it is annual. Also arh see what you mean about lighting it i will try the match test and cut a sample next time am passing. thanks for the input......any takers??

[stevelucocq]

Looking like its G.Resinaceum from what i have been reading and looking at on the web??....I.dryadeus looks very different when mature but when this was developing looked just like it.....cheers for the input, anyone else got any more data?

I wanna lnow about the lighter test...only reply if your info is reliable cos I cant find ref to it and I gettin' bored lookin'.....thankyou!

ok in principles of tree hazard assessment and management - d lonsdale (FC) it say about g.pfeifferi (p105) and g.resinaceum (p106) have a varnish like resinous crust that melt when exposed to a flame. it also states g.res is less hard than g.pfei....cheers
