Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
We now have THREE other species of this group on British coasts. H. aractina, previously known from northern Norway has, I hear, just been found in Britain. H. oceanica and H. orae are the other two maritime species here.
H. maura remains much the most common.
(= Verrucaria maura in current books.)
Thanks for that valuable info. I wasn't aware that H. aractina needed to be considered too. I will revisit this group, but perhaps when I am feeling more brave. Sectioning perithecia is one of the more daunting things on my list.
