Keizer's Fungus guide

[David Humphries]

David,

In the "old days" (slides), Olympus 10n, 1 and 2 with Tamron macro zoom 90 mm 1:2.8 F32, in the digital era Canon EOS 450D with Tamron SP Di macro zoom 90 mm 1:2.8 F32 and Canon EW-78D EFS/IS tele/macro zoom 80-200 mm 1:3.5-5.6 F 32.

 

Thanks

 

heavyweight - do you ever carry a smaller cam for ease or always go tooled up ?

I was letting it grow unhindered!

[Fungus]

Gymnopilus junonius (G. spectabilis).

Annual, in clusters, cap convex to expanded, 5-15 cm in diameter, golden yellow to orange-yellow, covered with adpressed, fibrillose, yellow-brown scales, gills yellow to rusty brown, stem 5-12 x 1-3 cm, fibrillose-scaly, chrome to ochrous yellow, with membranous, yellowish to rusty brown ring and swollen base, flesh pale yellow, taste bitter, spores rusty brown.

Necrotrofic parasite, causing simultaneous white rot in (the base of) the trunks and roots of decideous trees, such as Betula (photo 1/2/3), Quercus robur/rubra, Fagus, Robinia, Castanea, Platanus and Prunus (photo 4).

Especially Betula, Quercus rubra, Robinia and Platanus can loose much of the rootplate at or below ground level and/or the major roots, with the last two tree species being incapable of regeneration of or compensating for the loss of the major roots, once they are destroyed. And the Prunus shows a very typical growth reaction on the trunk after the buttresses have been infected (photo 4).

got a lovely example on Alnus too

[Fungus]

No, just the digital Canon with two lenses and a small tripod, or if necessary, a bigger tripod, all carried in hand or a photo case and most of the photo's are made without artificial support of the camera.

Without bragging, I have a very steady/stable hand, I even can "catch" hoovering flies in flight with.

Stunning imagery

WOAH... love the second one:thumbup:

[Fungus]

Four species of Taphrina are depicted and described.

1. Witches' broom (Taphrina betulina), causing abnormal growth and deformation of branches and leaves of living birches, initially without damaging the tree much. Once more then one half to two-third of a crown is affected, the lack of foliage directly delivering energy (photosynthesis) to the trunk and the roots becomes detrimental to the tree.

2. Taphrina johansonii, during spring forming a golden layer covering the separate inflorescenses and fruits of the female catkins of Populus tremula hanging on the tree, which swell to a thickness of 10 mm.

3. Taphrina amentorum, during spring forming a green to red layer covering the seeds inside female catkins of alder, after which it partially sticks out looking like a flag.

4. Taphrina pruni, during spring forming a purplish layer covering the wrinkled fruits of Prunus species, such as P. spinosa, cherry and plum.

interesting stuff, especially the withces broom which i have seen plenty of but didn't realise what caused it.

 

on a side note are azaleas affected by taphrina species?

[Fungus]

are azaleas affected by taphrina species?

 

Rob,

Only the leaves are affected by fungi, such as Exobasidium vaccinii (see next post), or other Exobasidium species also living on/of leaves of Vaccinium species.

And there is another Taphrina species, T. deformans, which is also is a leaf parasite causing leaf-curl in peach foliage.
