Stinkhorns: with a smelly, brownish spore slime


 

The feature common to the fungi of this group is that, when mature, there is a smelly, brownish slime somewhere on the surface of the fruitbody. For those who have not had the joy of encountering a stinkhorn, think of a pit toilet or rotting meat and you get an idea of the aroma – though the strength of the smell varies between species. That slime contains the spores and attracts dung-loving or carrion-loving insects that act as dispersal agents.

 

Stinkhorns vary considerably in shape when mature. However, another thing that they all have in common is that each fruitbody starts out like a small egg, the 'egg shell' being a membrane that envelopes the immature fruit body. Initially the ‘egg’ is fairly firm but becomes softer as development proceeds. Finally, the fruitbody expands, breaks through the membrane and assumes its mature shape.

 

Warnings

The ‘egg’ may be buried in leaf litter or soil and could be mistaken for an immature puffball or make you think you’ve found a truffle.

Thanks for that Heino. Lesson, to look at the whole organism!! It would be interesting to do some DNA work on these to see if there is more going on here............

I reckon it's Clathrus. Most of the spore slime has gone but you can still see some remnants well out along the arms. That is a feature of Clathrus, whereas in Aseroe the spore slime is confined to the central area. CNM has had some other sightings of Clathrus with the ends of the arms split. I assume that, as with any organism, things can sometimes go awry during development and that the signals controlling arm development are more susceptible to disruption than those controlling the place of spore formation.

Thanks for the help in the identification. It can be confusing as some of the specimens at the same location do not have the branched "limbs" whilst others do. For some reason the organism seems to be very localised but associated underneath bushes. Our landcare group spread some mulch a few years ago at the location but same batch of mulch was also used in other areas and the organism is not apparent at any other location. To call this lifeform weird is an understatement.

@Pam more proof that these are alien beings! 😉
