These two fungi, found on Ash keys, were last week’s record of the week at my local biodiversity records centre, SEWBReC – not my record, that of another local recorder – but seeing this on Twitter last Friday reminded me to check the next Ash trees I saw. That opportunity came on Sunday’s walk and I found the fungi on just the second tree I passed by.

The two fungi are Diaporthe samaricola (the small black dots on the seed part of the key, on the left below) and Neosetophoma samarorum (the much smaller, black speckles on the wing part of the key, on the right in my photo). Both fungi are under-recorded in my area, so I’ll now be checking all the Ash keys I find.
