A Week on Muck

I have just spent a rather wet and windy week on Muck with the Inverness Botany Group. I decided to record on a monad (1 km square) basis as there are only 13 and none has 100% land. However, it spreads over four 10km squares, three of which have no other land in VC 104. We made over 1,800 records and as well as re-finding old records of many species, we added Carex extensa (Long-bracted Sedge), Carex limosa (Bog-sedge), Carlina vulgaris (Carline Thistle) and Valeriana officinalis (Common Valerian) to the Muck list.

Fumaria bastardii (Tall Ramping-fumitory), distinguished by its large flowers but small stipules, was a good find with only two previous sites (on Muck and Eigg) in VC104 and no record since 1999.

Some Myriophyllum in  brackish pools led me to hope for M. spicatum for which there are no accepted records for VC 104, as this is the habitat in which it is found on Coll and Tiree and the Outer Isles.

However, the inflorescence being <3cm and the tip drooping in bud plus the basal whorl of flowers being in leaf-like pinnatisect bracts then others in pectinate bracts, tells me that it is the locally frequent M. alterniflorum.

We also recorded a number of insects, mammals…..

The Belted Beauty has yet to be recorded on Skye.

Also fungi, some of which are awaiting identification….

Later: Bruce tells me the fungus on Silene flos-cuculi is Septoria lychnidis, or as NBN has it Caryophylloseptoria lychnidis, and that it is found on other members of the genus too.
