Keizer's Fungi Q & A.

[Tony Croft aka hamadryad]

First an odd annual bracket on old alder, around a lake. i have a shot somewhere of a fresh pore layer looking decidedly grey in colour when it was fresh, ive no ideas, thought at first Hapilopilus nidulans but know better now!

 

 

I am certain this is the asexual stage of B. iquinans on beech, the one that failed, these fronds where shortly followed by the B. iquinans, and made the conection, but was it the right one?

Matt,

Or provided the annual brackets are spongy and soft, it is a Postia or Tyromyces species, which depending on the species, causes a white or a brown rot.

 

Ta fungus. Just been looking through my facebook albums and found same fungus. In the first two pics its Postia ptychogaster. Still not sure about the second pair of pics.

Matt,

1. O.k. with me, but note, that both the anamorph and the teleomorph of Oligoporus ptychogaster only grow on dead wood of coniferous trees.

2. I'm 90 % sure its is Hypholoma (= Psilocybe) fasciculare, the only other possibility would be H. capnoides, provided it grows on dead coniferous wood.

Tony,

1. In my opinion, this is an old bracket of Ganoderma lipsiense, which has "recycled" its inner tissue and of which the remains of the tubal and pore layers have been "destroyed" by the falling off of the nipple galls of Agathomyia wankowiczi. To be sure, you'll need to collect some reddish brown spores and check their size with a microscope.

2. Of Bulgaria inquinans, no anamorph (of the genus Chalara) is documented, see : MycoBank, the fungal website. I would suggest it is the "dripping down" plasmodium phase of a myxomycete, such as Badhamia utriformis.

interesting resinaceum that first one, ive never seen one that wasnt entirely sessile?

 

Tony,

Neither did I, until I "met" this atypical one, which looked like a very large G. lucidum, but after determening its microscopical characteristics, turned out to be yet another type of emergency reproduction fruiting of G. resinaceum.

:thumbup1:great thread thanks for sharing your knowledge with us gerrit

Crikey, but it is the difficulties within mycology that make it so interesting:thumbup:

 

if a little mind bending and incredibly frustrating at times!

 

you think you know, and then they pull a stunt like that on you!

goedemorgen Gerrit,

 

here's a fungi that Tony, a colleague & myself have considered.

Would be appreciative of your thoughts.

 

Unfortunately these are the only images, I seem to have misplaced a slice shot

 

It appears to be of an annual nature. Although soft in developement the latter shots depict a hard crust.

 

thanks

David,

Goedemorgen too, although it is 10:33 AM (summertime), i.e. 2 hours later over here.

Without slice difficult to say. A wild guess would be, it is a sterile perennial, poorly developed bracket of Ganoderma lipsiense, of which the mycelium has stopped fruiting after the beech closed it in and shut the mycelium off of its food or energy supply.

Gerrit, it's always 1 hour later in NL than in the UK, zomertijd en wintertijd veranderen op het zelfde moment, whereabouts in NL are you from? I'm guessing you're not a Randstad person?
