Star Gilia Gilia stellata

Description

Goes to genus Gilia rather than Saltugilia in the Jepson eFlora Polemoniaceae key from "inflorescence glands long-stalked, diam < stalk (hair)". [Note: Click the photos twice to view large images where infl. glands can be discerned.]

In the Jepson eFlora Gilia key the lack of an in-focus view of the leaf hairs here prompted me to go "both ways" at couplet 10, yielding candidates G. stellata (immediately) or G. scopularum (after a number of ensuing key breaks). The latter is described as having "corolla tube purple, throat < tube, yellow" and the former "corolla 6--10 mm, funnel-shaped, tube included or +/- exserted, throat yellow with purple spots, lobes pink or white". So G. stellata seemed better here.

I also checked the Gilia key in Munz...where from (among other characters): pollen blue; corolla funnelform; no arachnoid hairs; infl. open; plants scapose; and fruit capsules ovoid...one arrives at a terminal couplet between (surprise!) the same two species: stellata and scopularum. The relevant break there (since, again, leaf hairs are not visible in my photos) was: "corolla tube included in the calyx" for stellata vs. corolla tube well-exserted for scopularum. This break again pointed to G. stellata.

Cross-referencing with Tom Chester's Gilia of San Diego County web page reinforced the putative ID of G. stellata.

I think the orange filamentous algae is Trentepohlia, from an earlier suggestion of @catchang regarding similar looking items in an previous post.

Don't know whether the shiny black entity is a gelatinous lichen or a(n unlichenized) fungus.

Intriguing lichen garden on rock outcrop of a moist, shaded, north-facing road bank.

I think I see at least two species each here for all three of the main lichen forms: fruticose, foliose, and crustose forms.

Description

On dead twig that appeared to have fallen from a douglas fir. Looks like it's disintegrating (at least the apothecia do).

I attempted to key this from the photo using "Lichens of California" by Hale & Cole(1988). I ended up with genus Hypogymnia.

Description

Growing on trunk of a Eucalyptus tree. In the 2nd image here, I think there's some Cladonia near the center...and a paler brown thallus, which I'm quite curious about (I'm wondering whether it's perhaps a senescent or dead & discolored piece of the same Parmotrema elsewhere in the image?).

Found on rock embankment (rock type = graywacke?). I'm thinking this is likely Xanthoparmelia...perhaps X. cumberlandia ?

Image showing the road bank habitat image can be seen here.

Best guess at the rock substrate is graywacke. Mosaics of many different lichen species. The largest most conspicuous rosettes look like Xanthoparmelia, perhaps species X. cumberlandia ? See this iNat post.

Camera pack provides scale. Some of the Xanthoparmelia rosettes are quite large...I wonder how old they are?

Growing on tree bark (perhaps an oak, don't recall for sure).

Didn't catch an ID for this one from fellow California Lichen Society field trip members...it looks similar to the image of Xanthoria polycarpa at this link, but I suspect a mere likeness may not be sufficient grounds for a decent ID with this "new-to-me" and seemingly quite subtle class of things called lichens!

Description

The black lichen at center with the "tubular gummy bear" gestalt is Collema nigrescens. Growing on tree bark (don't remember exactly, but believe it was a willow or an oak). Found & identified by Tom Carlberg of the Calfornia Lichen Society...thanks, Tom :-)

(Curious about the green leafy lichen on lower border, and orange filamentous stuff at upper right?)
