Elucidating "lucidum": Distinguishing the diverse laccate <i>Ganoderma</i> species of the United States - Fig 4

<p><b>Contextual colors (A) and features (B) of the laccate <i>Ganoderma</i> species of the U.S. (bars = 20 μm)</b> A) broad categories of the context tissue colors, where arrows point to context tissue; i) white context tissue (324WI, <i>G</i>. <i>tsugae</i>), ii) light buff to cream context tissue (112CA, <i>G</i>. <i>polychromum</i>), and iii) dark brown context tissue (265FL, <i>G</i>. <i>zonatum</i>). B) contextual features such as melanoid bands (“Mb”), concentric growth zones (“Cz”), and contextual chlamydospores (“Ch”); i) melanoid bands embedded in context tissue of pileus and stipe (158FL, <i>G</i>. <i>curtisii</i>), ii) concentric growth zones in context tissue of the pileus (171FL, <i>G</i>. <i>sessile</i>), iii) close-up (10x) of melanoid bands in the context tissue of the pileus (NCSCLG 1804, <i>G</i>. <i>curtisii</i> f.sp. <i>meredithiae</i>), iv) close-up (10x) of melanoid bands and concentric growth zones in context tissue of the pileus (NCSCLG 19006, <i>G</i>. <i>martinicense</i>), v) double walled, globose contextual chlamydospore (255FL, <i>T</i>. <i>colossus</i>), and vi) double walled contextual, globose chlamydospore with striated margin (FLAS F59210, <i>G</i>. cf. <i>weberianum</i>).
