Basidiocarps resupinate, adnate, effused, up to 100 [micro]m thick in section; hymenial surface smooth, pruinose, grayish white when fresh, not changing much on drying; margins thinning, paler concolorous
, to indeterminate.
0.6 cm, tomentose, leaflets 5.5-11 x 3-6.5 cm, concolorous
, chartaceous to membranaceous, elliptic or oblong, apex acuminatte, rarely rounded, margins entire, base rounded to cuneate, venation penninerved, both surfaces with tector trichomes restricted on the midrib; tendrils simple.
Poisson (1959) presented a key to the species of Macrocoris in which the first couplet divided the taxa based on connexival colour pattern; one group was concolorous
or nearly so, and the other had the posterolateral corners black or densely maculated.
Thorax: pronotal disc with 2 salient black tubercles near to interruption of suture that sets off prozona from meso- and metazona; lighter medial sinus, almost white; small dark-brown and black dots, concentrated laterally and close to medial sinus, small concolorous
tubercles dispersed over the disc.
Flowers are actinomorphic, with a tubular light violet corolla (4.16 [+ or -]0.02 cm long), three free petals and sepals, petals 2.5 [+ or -]0.1 cm longer than sepals, corolla remains straight during anthesis, with exerted sexual organs, six stamens in two series (4.3 [+ or -]0.38 cm the shortest and 4.8 [+ or -]0.2 cm the largest one), concolorous
with the petals, a white, conduplicate spiral stigma in an elongated, white style 6.04 [+ or -]0.06 cm long.
Abdomen pale yellowish grey, with dark, chocolate brown, lancet-shaped longitudinal median band connected to a concolorous
, dark posterior quarter with white chevrons (Fig.
Spiracles pale, inconspicuous; all legs concolorous
. Wax glands formed ventro-laterally on the anterior margin of abdominal segments 7 and 8 when caterpillar mature.
Thallus areolate, with lobed margins, yellow green; apothecia 0.5-2 mm in diameter, disk yellow or brown, margin concolorous
with thallus Lecanora muralis 2.
variegatifolia; the leaves are concolorous
, green, ovate to ovate-lanceolate in outline, usually conduplicate along their midrib with epicuticular wax over a striated or folded epidermis.
The inconspicuous thallus and numerous small, plane, deep reddish orange apothecia with concolorous
margins are characteristic.
