Large and prominently ribbed with distinct lobes, Lyscom has an open calyx and a very shallow stem well. Its blush is a streakey blotchy wash of dull red and purple over green: the effect is almost brown in places. Large Lyscom unbroken has a sweet grassy aroma and a firm feel. The flesh is light yellow, moderately crisp, and slightly coarse. Lyscom's flavor is balanced with some tartness, pear at first giving way to some astringent notes: lemon, spice, and a vinous quality.
