Species Information
Summary: Features include 1) resupinate growth on hardwood limbs, 2) a thin, whitish fruitbody, the surface cracked when mature exposing cobwebby subiculum, 3) spores that are small, smooth, inamyloid, and colorless, 4) 4-spored basidia, 5) hyphae with clamp connections, the hyphae encrusted in the subhymenial area.
Athelia scutellaris has been found in BC, MB, ON, AZ, AL, DC, FL, GA, IL, IN, KS, KY, LA, MO, MS, NC, NJ, NM, NY, PA, SC, and VA, (Ginns).
Fruiting body: resupinate, long and widely effused [spread out], 2-8cm x 1-4cm, thin, 0.012-0.025cm thick in section, adnate [tightly attached], "from white becoming cream-buff to warm buff in the herbarium"; waxy, often granular, finally cracked, the cracking pattern may be into minute areolae less than 0.1cm (and often flaking away), or into more rectangular masses up to 2cm wide; margin thinning out, (Burt), pellicular, thin, becoming widely effused; white; "cracking and exposing the white, loosely interwoven, arachnoid subiculum in the fissures", (Gilbertson)
Microscopic: SPORES 4-6 x 2-3 microns, smooth, colorless; CYSTIDIA absent; hyphae 2.5-3.5 microns wide, "suberect, interwoven, thin-walled", "incrusted in the subhymenial region so as to form a conspicuous subhymenial zone of mineral matter", (Burt), SPORES 4-5 x 2-3 microns, elliptic, smooth, inamyloid, colorless; BASIDIA 4-spored, 3.5-4 microns wide, clavate; SUBICULAR HYPHAE 2.5-4 microns wide, "thin-walled to moderately thick-walled, nodose-septate, conspicuously incrusted in the subhymenial zone", (Gilbertson)
