1.2 mm, 250-275 |im thick, tips splayed and strongly crenate
upper surface: pale or dark brownish-gray, darkening where most exposed,
faintly mottled pattern in places, epruinose to weakly pruinose in a few places

±60 jim below, brown upper 5 near top of margin in places, prosoplect.,
hyphae 3-7 \xm with 1.5-2.5 \xm walls, algae abundant in margin to patchy
below or even absent toward center
paraphyses: 1-1.5 ^m below to 3-5 jim at tips, weakly capitate and some
