“203a Basidiocarps variously formed, spread out flat and irregularly rounded, brain-like, mesentery-like, or weakly cup-shaped; ocher-pink, grayish ocher, to salmon-colored; basidiocarps initially petal-like, one or more arising from edges of conidial sporocarps that are minute, bright pink to orange, and shaped like complex cups; in Europe on Prunus spp., in British Columbia growing on shredded inner bark of Populus trichocarpa
……………………………………………………………………..Craterocolla cerasi
BASIDIOCARP 1-5 cm across, variously formed: petal-like, weakly cup-shaped, spread out flat and irregularly rounded, lobed, foliaceous, brain-like, or mesentery-like; sometimes short-stipitate, upper surface smooth, consistency gelatinous-glutinous; ocher-pink or gray-ocherish or salmon-colored. Conidiomata, usually appearing as aggregates before the basidial stage, are minute, bright pink to orange, complex cups: stalked, top-shaped, urceolate, with a membranous, stellate closure, colored as basidial form but not gelatinous, small but clustered and conspicuous. The basiocarps often develop as paler, spathulate or rounded lobes from one edge of a conidioma, resembling an Exidia or Tremella, petal-like in form at first but soon obscuring their origin and becoming clustered. HABITAT near Ladner in southern British Columbia found on bark of Populus trichocarpa, especially well-weathered (shredded) inner bark that has fallen away from dead trunks and has become trapped on shrubs below in cold winters (especially those with snow). It is also present on the inner layer of bark on the ground and it has been observed on the pith of the sawn end of a log. It is not certain that this is the same species as Craterocolla cerasi (Schumach.) Bref. which occurs in some areas of the world on dead trunks and branches of Prunus spp., occasionally other hardwoods. MICROSTRUCTURES spores 8-11 × 3.5-4.5 um, curved-cylindrical, conidia 6-8 × 2.5-3.5 um; basidia longitudinally septate, 4-spored; cystidia not seen; no clamp connections. REMARKS Craterocolla cerasi differs from Tremella by the separate occurrence with C. cerasi of conidiomata which usually appear before the basidium stage.”
