A common mushroom which can appear pretty much any time in the second half of the year. Brown roll rims have a mutually beneficial relationship with many types of trees. The underground section interpenetrates with the roots of the host tree. The fungus uses the tree as an energy source, and in return gives up minerals which it has got by breaking down dead organic matter in the soil.
The funnel shape of the cap is often more pronounced than in these specimens.
Two of the exposed, partially overgrown, rock faces on the former quarry on Barrow Hill, in the LNR of the same name in Pensnett.
The quarry was for a hard rock of volcanic origin, diorite, which is a form of basalt. Dudley Council market Barrow Hill as the “Dudley volcano” (it erupted300-odd million years ago).
Diorite was also quarried just across the borough border in Sandwell, where the Rowley Hills were the source of Rowley Rag.
Members of the crow family tend to be sociable birds. These pictures are of about half of a flock of jackdaws. Two members of the flock were also featured eating alongside gulls a couple of days ago.
Like yesterday’s mushroom, these waxcaps have a viscid surface because they are moistened by the melted frost from the previous night. They were growing in the same patch of mossy grass as that mushroom.
The pictures were taken during December’s cold spell, not the current one.
My guess is that this is too small to be a squirrel’s dray, so that it is a bird’s nest in an oak tree. I wasn’t going to stand around in sub-zero temperatures to find out if something came along to use it.
Another in the continuing series of mushrooms which are so tiny they can only be spotted by close inspection of the short grass in which they are growing. This one was glistening with water formed by the melting of the frost which had settled on it the previous night.
