Mushroom Observer Image 545932: Collemopsidium foveolatum (A.L. Sm.) F. Mohr

Description: Collemopsidium Nyl. Image location: Lummi Island, Whatcom Co., Washington, USA Superficial on intertidal Si rock with barnacles. (Sometimes grows up onto the barnacles from the rock.) Of the 3 marine Collemopsidium species on the North American checklist (also considering the species in Smith et al.) the most possible would be C. halodytes, but this seems very distinctive. No photos which I can find online resemble this. I would appreciate suggestions on this one.

Description: Collemopsidium foveolatum (A.L. Sm.) F. Mohr Image location: Lourinhã, Portugal This observation refers to the lichen growing on barnacles that is noticed as black dots over the shell. Following the key in the reference one arrives to the pair of species C. foveolatum and C. sublitorale. They mainly differ by the size of perithecia, though overlaping (0.1-0.2 mm for the former and 0.15 – 0.5 mm for the latter). I estimate that the size of perithecia (involucrellum included) is consistently less than 0.2 mm, which makes C. foveolatum a good choice. I will try to make the microscopy, though the dimensions for the spores of the two species are also similar.
