Microscopic examination of mature apothecia (and sadly they are often <i>not</i> mature) is usually necessary even to be sure of the genus, and field identification of all but a few distinctive species is risky. Dobson (2011), pp. 236-7, gives an invaluable analysis of the component genera.</p> <p>FGBI: <a href="http://fungi.myspecies.info/all-fungi/fuscidea-kochiana" target="_blank">http://fungi.myspecies.info/all-fungi/fuscidea-kochiana</a></font></div></td></tr> </table> &nbsp; <table> <tr><td align=center><img src="Fuscidea_kochiana_P4016525.jpg" border=1 vspace=5 alt="Fuscidea kochiana"></td></tr> <tr><td align=center><font face="arial" size=2>On upland boulder, Mar Estate, Aberdeenshire, April 2008</font></td></tr> </table> <p><br></p> <table border=0> <tr><td><a href="Fuscidea_gothoburgensis.html" target="_top"><img src="baru6.gif" border=0 alt="Previous page"></a></td> <td width="50">&nbsp;</td> <td><a href="Fuscidea_lightfootii.html" target="_top"><img src="baru8.gif" border=0 alt="Next page"></a></td></tr> </table> </center> <p><br></p> <p><hr></p> <center><font face="Arial" size=2> <p><b><a href="index.html" target="_top">Lichens HOME PAGE</a> | <a href="indexP.html" target="_top">Index of Species</a> | <a href="http://www.lastdragon.org/conditions.html" target="_top">Conditions of Use and e-mail contact</a> | <a href="references.html" target="_top">References</a> | <a href="http://www.lastdragon.org/home.html" target="_top">Site Home Page</a></b></p> </font></center> <p><br></p> <font face="Arial" size=2> <p>&copy; A.J.
