Jamesiella anastomosans (P. James & Vězda) Lücking, Sérus. & Vězda

Apparently the most common member of the broadly circumscribed genus Gyalideopsis in the central Europe. It is usually recognized due to transparent cylindrical protuberances that resemble isidia – the so-called thlasidia, formed on a shiny thallus. Jamesiella anastomosans is locally common in pioneer communities of microlichens. The species prefers rather humid and shady types of both the old-growth and managed forests. It grows on acidic substrates, most often on lying decaying wood and thin twigs. However, it may be found also on tree bark, on bryophytes and sparsely also on stones. In the north-Bohemian sandstone area, the lichen is very common. In contrast, it is probably rare in dryer regions.
