Tis the season to see Fungi, fa la la la la....

[David Humphries]

I could have put this in me own thread but well thought i would share it with my long lost mate monkey!

 

another new species for me, and WW:thumbup1: waited so long for this one:biggrin:

 

Plums-and-Custard Fungus (Tricholomopsis rutilans)

Very nice find & shot

David,

Of course it is , but tell me, how do you British keep your mycoflora databases clean of faulty identifications, if no microscopical evidence and storage of well documented and described collections in qualified herbaria is demanded ?

In The Netherlands, before the "standard list" of Dutch macrofungi was published in 1995 and the first Red List in 1996, we had a review of all official herbarium collections, after which a lot of the collections from the national herbarium had to be removed because of faulty identification, which could not be restored because of insufficient documentation.

Nowadays, findings of all very rare to extremely rare and/or Red List species have to be identified by specialists, if the identification of the species is a "tough case", or to be checked by a specialist if a second opinion is asked for, to be accepted for the mycological data base.

 

Gerrit, here in the Uk records are checked, recorded and stored at the Herbariums of the Botanical Gardens at Edinborough & in London at Kew.

 

The British Mycological Society are charged with running the Myco show in terms of research/education & field mycology & conservation over on this side of the water.

 

 

Us 'students' are here to learn & interpret what we see/read & then pass on our knowledge for the greater good of the Tree Industry at large.

 

 

If in particular doubt about a specimen (both privately & through work), I send mine down to Dr Martin Ainsworth at the Jodrel Lab at Kew or to local Mycologists who have access to the scopes & literature that I do not have.

Been away from work for a couple of weeks, here's what's on the door step that I've seen over the last couple of days.

 

Some I know, some I will know, some I don't know.

Right when am i getting an invitation!

 

you got some funky fungi man!

[David Humphries]

Doors always open Tony, you know that.

Have quite a few free evenings now. Could always do a midweek after work?

Went back for a sweeter shot today, put the headtorch on it!

David,

It's in good hands then, that is, as long as it's done properly by all arborists identifying macrofungi and the type of woodrot they cause as part of their work on trees and writing reports for their customers.

Going through my database from the 11 years I provided identification services to Dutch and Belgian arborists and tree officers of municipalities, I came across these figures of false identification by the sender of the specimen.

Of all the 974 identifications :

- 117 were of what was supposed to be K. deusta, of which 9 turned out to be Diatrype stigma, 17 turned out to be either Hypoxylon serpens, H. rubiginosum or Hypoxylon multiforme, 2 were FB's of Chaetosphaerella phaeostroma, 1 turned out to be (the very rare) Camarops polysperma, 12 were melanine sheets of Armillaria species and 14 were of non-fungal origin.

- 79 were of what was supposed to be an (necrotrophic parasitic) Armillaria species, of which 4 were of Gymnopilus junonius, 1 was of Agrocybe aegerita, 4 were of Pholiota aurivella and 7 of (the biotrophic parasitic) P. squarrosa.

- 24 were of what should be Meripilus giganteus, of which 5 were of Grifula frondosa and 7 were of what should be G. frondosa, of which 2 were M. giganteus.

- 36 were of either Ganoderma lipsiense or G. australe, of which only 12 were identified correctly and G. australe turned out to be the species in 31 of all cases.

- there were 9 mix ups between Fomes fomentarius, Fomitopsis pinicola, Ganoderma species and Phellinus species, 7 mix ups between Bjerkandera and Trametes species and 4 between Chondrostereum purpureum and Stereum species.

- 19 were sent being Pleurotus ostreatus, of which 2 were P. dryinus, 1 was P. pulmonarius, 2 were Hypsizygus ulmarius, 1 was Paxillus panuoides, 1 was Pholiota populnea and 2 were of Panellus serotinus.

- and there were 7 cases of wrong identification of what turned out to be Lenzites betulina, Phylloporia ribis, Abortiporus biennis (2 x) and Heterobasidion annosum (3 x).

 

So of all specimen about two third was identified correctly by the sender. I wonder what would have happened to some of the trees without my intervention.

And thats why we try so hard!

A few fung from the past few months

1,2 Boletus sp nr Betula

3,4 Phallus impudicus by failed Larix nr Abies

5, Unidentified Nr Qurcus/Taxus/ Ulmus

6,7 Think Russula sp Nr Tilia/Castanea

Not been on for ages, finally got a new computer and really enjoying catching up on the threads. :thumbup1:
