Summary
| Description |
Peltigera degenii Gyelnik Image location: Mount Wilson, San Gabriel Mountains, Los Angeles Co., California, USA This was from the largest of three populations on the Mount Wilson Toll road, a mile or so above Henniger Flats. Growing on old moss-covered soil cut-bank in old oak forest on low-angle north-facing slope at around 3500 feet. This keys out clearly as P. polydactylon in the Sonoran flora (absolutely no tomentum on surface, saddle-shaped brown apothecia, and obviously not P. neopolydactyla). But the more I look at it the more convinced I am it looks significantly different from the P. polydactylon I know from BC and NC. The veins, for example, are too well-developed and narrow; the interspaces are hardly “highly constrastive”. Apothecia are far too rare (only two or three in dozens of very well-developed thalli), and broader than I’m used to. Some regeneration lobules are present on margin edges and cracks, but this is not uncommon for polydactylon. Also the lobe tips are often conspicuously pruinose (see bottom photo), and the overall texture is less shiny than usual. Used references: Trevor Goward — dull surface, pale underside with narrow raised veins.
