It is characterized by having small and thin basidiocarps, a sharp pileus margin, ventricose hymenial setae, and ellipsoid, yellowish and thick-walled basidiospores.
32.
It has bright orange, yellow or occasionally white branching basidiocarps, which are somewhat gelatinous in texture and slimy to the touch ( hence the specific name ).
33.
Tomita et al . 2004 purified pleurotolysin, a sphingomyelin-specific two-component cytolysin from the basidiocarps of " Pleurotus ostreatus " and studied pore-formation.
34.
Basidiocarps are classified into various types of growth forms based on the degree of differentiation into a stipe, pileus, and hymenophore, as well as the type of hymenophore, if present.
35.
Species within the family have gelatinous basidiocarps ( fruit bodies ) that produce spores on septate basidia and, as such, were formerly referred to the " heterobasidiomycetes " or " jelly fungi ".
36.
The sexual reproductive structures of the fungus, annual or perennial basidiocarps, appear on decomposing stumps and at the base of dead trees and release spores in summer and fall to mid-winter.
37.
When the fungus has obtained enough nutrients it grows a basidiocarp on the outside of a trunk or stump of a tree in the eastern US or inside a hollow stump in the western US.
38.
A study has shown that the formation of calcium oxalate crystals on the hyphae that form the endoperidial layer of the basidiocarp is responsible for the characteristic opening ( dehiscence ) of the outer peridial layers.
39.
It is distinguished by its resupinate and rigid basidiocarps, its yellow pore surface, being microscopically ellipsoid and yellowish brown, its thick-walled basidiospores, and by lacking both setal hyphae and hymenial setae.
40.
Morphologically differentiation is most reliably made through pore density of the basidiocarps as " H . irregulare " has a lower density than " H . occidentale " with more oblong and larger pores.
