Deformation during growth?

[Colin Lofthouse]

Hi everyone. Following an answer in another thread to ID a weird looking bolete? The answer threw up the idea of secondary mould infection. And deformation during growth of the fruiting body. I'm interested If anyone has knowledge or examples of parasitic or secondary 'infection' that will affect it's formation. And what types of deformation have you seen? Strikes me that this lends a while new complication to identification. Excuse this possibly naive question. I new to the world of fungi bit am finding the whole thug facscinating.

There is no easy answer to this question as fungi which attack other fungi come in all shapes and sizes, but the mould you mentioned is extremely common on Boletes especially those close to Boletus chryseteron.
This behaves as you would expect a mould to be - it just rots down the fungus, but the mould itself goes through several physical changes.

You also have things like Boletus parasiticus which grow from the fruit bodies of Scleroderma citrinum and recently on this forum we had examples of Collybia species growing on old Russula and Lactarius fruiting bodies, and of course there was the Asterophora lycoperdoides on an old Russula sp.

A nice find would be Volvariella surrecta growing on old Clitocybe nebularis fruiting bodies.

You could try googling Syzygospora tumefaciens - this is a rare jelly fungus which grows on old species of Collybia.
