“Similar Species”

from wikipedia:

Similar species

Of more than a dozen species of Scutellinia, S. scutellata is the most common and widespread, though a microscope is required to differentiate between some of them.13 It is also the type species of the genus.1 It is differentiated from most other Scutellinia by its larger size, and its distinctive “eyelashes”.11 Although David Arora describes S. scutellata as “easily recognizable”,6 it can be mistaken for S. umbrarum (which has a larger fruiting body and larger spores, as well as having shorter, less obvious hairs) S. erinaceus (which is slightly smaller, and orange to yellow in colour, with smooth spores), Cheilymenia crucipila (which is much smaller, with short, pale hairs and spores lacking oil droplets) and Melastiza chateri, which is bright orange with small brown hairs.6 The “Pennsylvania eyelash cup” (S. pennsylvanica) is a smaller North American version that has smaller hairs and spores that are more coarsely warted than S. scutellata.12 S. barlae is very similar as well, and can only be reliably distinguished by its roughly spherical ascospores that are typically 17–23 µm in diameter.18 Species from the Lamprospora genus are smaller and hairless.6 Similar fungi that favour dung over rotting wood include Cheilymenia coprinaria, C. theleboides, and Coprobia granulata while species such as Anthracobia macrocystis, Anthracobia melaloma, Trichophaea abundans, Pyronema omphalodes, Pulvinula carbonaria and Pulvinula archeri are cup fungi that favour burned-over ground.6

I find it interesting that despite the known diversity of this genus (much less the species waiting to be described), just about every sessile, red-to-orange, saprobic cup with black(ish) hairs of varying lengths at the apothecial margin, from Alabama to Alaska, gets called Scutellinia scutellata. MO alone hosts 75 so-called S. scutellata observations, a whopping two of which contain accompanying microscopy. While we await the world monograph, perhaps someone out there in ascoland can help sort through this lumperific mess.

Nothing at all against you, sir Jeff. It’s just a long-time beef which decided to rear it’s ugly head in your fine observation.
