Recognized by sight: Danny Newman (myxomop) states that species in this genus need microscopic examination and a good monograph does not exist. For me Eyelash peziza also works, especially for mycologists in the making.

Recognized by sight: fox’s very valid cautionary approach notwithstanding, the exceptionally large, long, and erect eyelashes at the apothecial margin point promisingly to this species, though I wouldn’t be the least bit surprised to find more members of the genus with this characteristic. update unlikely given S. erinaceus’ description, despite how long-eyelashed Scutellinia have typically been named on MO. see comments.

At least two kinds in Ohio

One is very common, around a 1 cm on average in diameter, and usually a scarlet red. The other, shown here, is much smaller, on average 1-2 millimeters, and never bright red as seen in the larger more common eyelash cups.

I’m not too concerned with names, as the names of all mushrooms change so frequently. There are at least two kinds of eyelash cups in Ohio. Shown here is the smaller less colorful kind.

To get an idea of the size look here:

perhaps some of the larger Scutellinia on the site are worth revisiting given S. scutellata’s apparent max apothecial diameter of 1.5cm.

Denison, William C., Some Species of the Genus Scutellinia. Mycologia, Vol. 51, No. 5 (Sep.-Oct., 1959), pp. 623-624.

Apothecia moderate-sized, 2-12 mm broad, scattered to gregarious, cupulate becoming shallowly concave or discoid; hymenium orange to red, “Spectrum Red” to “Grenadine Red,” rarely paler with a pinkish or salmon cast; rooting hairs abundant to scattered (100-)200- 700(-1300)μ long, the longest ones concentrated at the margin, 2-12-septate, dark brown, pointed, straight or slightly curved at the base, not abruptly crooked, simple; superficial hairs usually present; asci 15-20 × 240-320μ, cylindrical, eight-spored; ascospores (9-)11-14(-17) x (15-)17-19(-23)μ, mode length/width 1.5, moderately sculptured, containing one or more large guttules; ascospore sculpturing small, 0.1- 1.0μ broad, freely anastomosing warts, not visible in optical section; paraphyses subcylindrical to narrowly clavate, 3-5μ broad below, 5-9μ broad above, simple or, rarely, branched below.

Habitat: Commonly on rotten wood, bark, or soil; less often on a variety of other substrates: e.g., wood ashes, decaying leaves, and rotting sporophores of Fomes spp.; throughout the growing season.

Name: From Latin, scutella = a little dish.

If this description holds true today (which it seems to, at least according to Kuo who gives a “minute to 1.5cm” range), these appear to be well within the size parameters for S. scutellata (as well as a dozen or more other Scutellinia, no doubt). S. erinaceus was not listed in Denison’s publication, but the apparent hair length here — which MO images lead me to believe was one of the defining characteristics of the species — in fact rules that taxon out completely.

Moral of this Scuttelinia story… microscopy. Surprise, surprise.

Ten points for stephenfox.

Way smaller and orange

These really cannot be confused with Scutellinia scutellata which is around ten times larger on average and more red than orange.

the PNW key describes S. erinaceus’ hairs to be shorter than those of S. scutellata and having a more yellow-orange cup coloration than red. The images accompanying observations of S. erinaceus on MO do not corroborate this.
