What are they and is it usual for them to flower at this time of year Rob Taylor Hartlepool A Resembling tiny golf tees these lichens are probably Cladonia fimbriata distinguished by their abruptly expanding podetia stalks and fine granular skin . The species is common in loose soil on rocks and walls almost everywhere even in cities. The genus Cladonia includes some of our most familiar lichens such as c. portentosa used for realistic little bushes on model Ơ c o railways and devil s matchsticks which are upright with red tips. Lichens are not as seasonal as most fungi or green plants and you can find the podetia all year round. These are the fertile spore-bearing parts of the lichen that as in your photo rise from a mat of grey squamules . Their shape is ideal for shooting microscopic spores into the air.

They also described hundreds more from around the world including such icons as the Australian funnel-web and red-kneed tarantula. For half a century the duo contributed to virtually every paper .
