Vezdaea acicularis Coppins

Vezdaea acicularis is a well-recognizable species thanks to its long narrow multi-septate acicular spores. It is locally dominant (sometimes massively) in early successional stages on humid compact acidic sandy or clayey soils, at places with algae, pioneer bryophytes (e.g., Dicranella, Pogonatum) and lichens (e.g., Dibaeis baeomyces, Peltigera didactyla, Thrombium epigaeum). It may also colonize bryophytes on acidic rocks. The lichen resembles a pale-pinkish gelatinose fungus of Helotiales, but it is usually surrounded by scattered yellow-green granules (goniocysts), which look like algae colonizing surrounding detritus, bryophyte leaves and macroscopic lichens. The apothecia are formed for a short time only. During dry periods of the year, only the inconspicuous easily-overlooked thallus is formed. It is quite common on natural substrates, but mainly on anthropogenic stands, including contaminated toxic soils.
