This thin layer adnate crustose lichen was growing on the principal trunk of a living Quercus agrifolia, within the larger context of a mixed oak woodland on a steep rocky slope in western Annadel. The specimen did not shed powder when touched.
This adnate crustose lichen is extremely firmly attached to a sizable lateral limb of a living Quercus agrifolia. The thickness of the specimen appears to be about one millimeter.
Seen in a copse of Coast live oak trees growing on a fallen twig. The specimen is quite rigid.
Seen hard adnate on a native rock. This specimen measures about ten cm in diameter.
Seen growing on an old fencepost in a vacant lot on Snake Mountain. The lichen has a dust-like appearance with very fine grains, difficult to resolve with my camera in the ambient light.
Nearly missed these guys
Having just seen spectacular Caloplaca (I learned the name here on iNaturalist) in S. Australia, I was happy to find what looks like the same lichen here on the Olympic Peninsula.
This unusual fungus was seen in a shady ruderal area on Snake Mountain. The specimen was found beneath Douglas fir trees in a moderately heavy leaf litter of Douglas fir needles. This appears to be a large stinkhorn. The cap measures about 14 cm in diameter, and the texture is a hard rubbery substance, likely in its desiccated form as found.
This yellow lichen measures about five cm in its long dimension. It was observed growing on a twig in the riparian zone of Santa Rosa Creek somewhat east of the Flat Rocks confluence.
Ascomycota is a Division/Phylum of the kingdom Fungi that, together with the Basidiomycota, form the subkingdom Dikarya. Its members are commonly known as the sac fungi. They are the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (from Greek: ἀσκός (askos), meaning "sac" or "wineskin"), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning...
