Close-up of the apothecia of Cetrelia lichen. The shape of the apothecia is irregular, as the disks seem to have split into several pieces. The interior is slick red-brown while the rim is covered in short protrusions. Close-up of the lobes of Cetrelia lichen. The edge is wavy and there are white pseudocyphellae or white splotches all over the lobe. The other side of the lobe is light brown. There are tiny grains along the edge of the lobe base.

Cetrelia nuda, I think. This looks a lot like Punctelia ruderata because of the spiky appearance and white mottles, but Cetrelia has sawtooth lobe edge. Oiwakehara, Karuizawa, Nagano #Lichen

Enjoyable Saturday in the woods near Tilberthwaite with Cumbria Lichen and Bryophyte Group. Lots of good acid bark stuff including (everybody's) favourites Cetrelia olivetorum; Hypotrachyna laevigata and Bunodophoron melanocarpum. #LichenGBI
Cetrelia olivetorum var cetrarioides on an oak tree. Hypotrachyna laevigata 3 folk on a steep hillside looking for lichens Bunodophoron melanocarpum- the trumpets are fruiting bodies with a black spore mass. This is the only known population in the Windermere or Coniston catchments.

Huge specimen of Cetrelia sp., possibly Cetrelia braunsiana. This one is so gorgeous with the distinct psueudocyphellae and aggressive isidia. This even had apothecia which seem to be rare. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends

Close-up of the isidia along the edge of lobe of Cetrelia lichen. The isidia are small balck protrusions that are abundant alon ghte lobe edge and some on the surface of the lobe. The lobe edge is wavy. Colony of Cetrelia lichen on stone lantern. There are dense isidia in the central part of the colony, and they become confined to edge of lobes as it spreads out. There are no isidia on the extreme tip of the lobes. Here, there are clear white markings and black edge. Some apothecia in the middle part (not clear in the photo).

Found a cluster of Cetrelia sp. on ground. It has the distinct mottled appearance, but definitely not Punctelia due to the powdery soralia on edge of lobes. Lake Megami, Tateshina-machi, Nagano #Lichen

Cetrelia nuda, I think. The characteristic dotted edge seem to be more prominent on the smaller lobes in the center. They look gorgeous and lettucey in the rain. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends

Some pale lichen: Ricasolia amplissima with black cephalodia. Cetrelia olivetorum with either pyncidia or an LF. and Crutarndina petractoides which is a small immersed Thelotrema. #LichenGBI
Ricasolia amplissima with black cephalodia Cetrelia olivetorum - but which one? Cetrelia olivetorum - is that pycnidia or an LF? Crutarndina petractoides used to be Thelotrema and has a similar exciple with the fruit but not in a wart

Sunday stroll "accidentally" took us past an isolated bit of south Lakeland's mostly vanished Lobarion. Nephroma parile, Cetrelia olivetorum and Peltigera horizontalis still hanging on. Parmeliella triptophylla too. But I should go back soon to do some monitoring and pruning....

I think this is Cetrelia braunsiana. I love the texture (in lichenology lingo, the white spots are called pseudocyphella) that makes it look like an old tea ceremony bowl. Lake Matsubara, Koumi-machi, Nagano #Lichen

Cetrelia sp., possibly C. nuda. Not Punctelia. The major give-away is the large leaf-lettuce lobes with brown edge, as well as the tiny, round protrusions along the edge of the lobe in the central part of the colony. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends

Cetrelia cetrarioides is an uncommon rag lichen living on red alder in low elevation riparian forests in the Pacific Northwest. Distinguished by pseudocyphellae on the upper & lower surfaces & elongate soralia along smooth thallus margins. Seen here along Mill Creek in downtown Turner, Oregon.

Chicita's Sea Storm Lichen - Cetrelia chicitae
New to me
I will wholeheartedly announce that I don't like this genus. It generally requires multiple spot tests to ID accurately, the confirming tests might not always be positive, and even when they are positive they're extremely faint.
