I seem to remember a few of these.
Can you recall which books mention this phenomena?
1. FIVE GO OFF IN A CARAVAN 1946
He got to the hole in the roof and popped his head through. He gave a cry of astonishment.
'I say! There's a most ENORMOUS cavern here — bigger than six dance-halls — and the walls are all glittering with something — phosphorescence, I should think.'
He scrambled out of the hole and stood on the floor of the immense cave. Its walls twinkled in their queer light, and Julian shut off his torch. There was almost enough phosphorescent light in the cavern to see by!
One by one the others came up and stared in wonder. 'It's like Aladdin's cave!' said Anne. 'Isn't that a queer light shining from the walls — and from the roof, too, Julian?'

After a long crawl along the ledge the tunnel opened out into a series of
caves, some large, some small. The boys marvelled at some of them, for the
walls were agleam with queer bright stones. Mafumu did not like them.
“The walls have eyes that look at Mafumu,” he whispered to Jack.
That was a very strange journey through the heart of the Secret Mountain.
Sometimes the river ran through big caves, which gleamed with green
phosphorescent light.

They came to another cave. The roof of this was not so high as the one
before, and only small, icicle-like stalactites hung from it. “Do those stalactites shine in the dark?” asked Dinah suddenly. “I
thought I saw something glowing in the corner over there.”
Jack switched off his torch—and immediately the children gasped. For
up in the roof and over the walls there glowed thousands of tiny stars.
They were green and blue, and shone and flickered in a most enchanting manner.
“Gracious! What are they?” whispered Dinah, amazed. “Are they alive?”
The boys didn’t know. They watched the shimmering, flickering stars,
that seemed to go in and out like elfin lights. “Might be a kind of
glowworm,” said Jack. “Aren’t they lovely?”
He put on his torch again and the roof shone brightly in the yellow-white
light. The stars disappeared.
“Oh, do put your torch out!” begged Lucy-Ann. “I want to watch those
stars a bit longer. I never saw anything so fascinating in my life! They shine
like phosphorescence—all blue and green and green and blue; look how
they flicker off and on. Oh, I wish I could take a hundred back with me and
put them on my bedroom ceiling at home!”
The others laughed at her, but they too thought that the shining,
flickering stars were most entrancing to watch. Jack did not put on his torch
again until each had gazed his fill.
“That’s two simply wonderful caves,” said Lucy-Ann with a sigh. “What
will the next one be? I really do feel as if we’d discovered Aladdin’s Cave,
or something like that!”
Any more??
