Translated from the Dutch Mycological Society:
Jan 13, 2016 – Due to the continuing mild weather until the end of December 2015 people could search for mushrooms. Also on Vlieland where an enthusiastic mushroom loving woman on Boxing Day on the road side along the road near the Kroonspolders found extremely rare earth tongues.
She was there looking for the rare olive earth tongue (Microglossum olivaceum), which had been found there in 2011. The earth tongues she saw now looked a bit like that species but were different. They had to be a different earth tongue species. Further identification by two mycologists found that it was Microglossum rufescens, a species that is extremely rare and does not even have a Dutch name. In November 2014 this species of earth tongue was first found in the Netherlands on an old graveyard in Zutphen. The discovery on Vlieland makes it the second site in the Netherlands.
