Ce lichen est du type foliac\u00e9 et l\u2019exemplaire de la photo est \u00ab fructifi\u00e9 \u00bb ; il a produit des apoth\u00e9cies, fructifications en forme de coupe (c\u2019est ce que tu appelles des fleurs), constitu\u00e9es d\u2019hyphes st\u00e9riles du champignon entrem\u00eal\u00e9s d\u2019asques, sorte de bouteilles en forme de massue contenant chacune 8 ascospores. Ces spores r\u00e9sultant d\u2019un acte sexuel du champignon sont donc des spores sexu\u00e9es qui, comme les spores asexu\u00e9es, assurent la propagation du champignon. Pour constituer un nouveau lichen, cette spore devra trouver l\u2019algue unicellulaire sp\u00e9cifique (symbionte photosynth\u00e9tique du lichen) avec laquelle il s\u2019associera pour reconstituer un lichen de l\u2019esp\u00e8ce <em>Xanthoria parietina<\/em>.<\/p>\n<p><strong>Merci pour cette r\u00e9ponse tr\u00e8s pr\u00e9cise<\/strong>.<\/p>\n<p><script src=\"http:\/\/www.google-analytics.com\/urchin.js\" type=\"text\/javascript\">\n<\/script><br \/>\n<script type=\"text\/javascript\">\n_uacct = \"UA-2472264-1\";\nurchinTracker();\n<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Il me semble normal de s&rsquo;int\u00e9resser \u00e0 tout ce qui touche \u00e0 notre environnement, ici ce sera du Lichen.<\/p>\n<p>Produit il des fleurs?<\/p>\n","protected":false},"author":1,"featured_media":128,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[9],"tags":[],"class_list":["post-129","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-archives-2009"],"aioseo_notices":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/plumalia.eu\/wp-content\/uploads\/2009\/12\/jpg_Mesange_bleue_lichen__Plumalia.jpg?fit=449%2C330&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/posts\/129","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/plumalia.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=129"}],"version-history":[{"count":0,"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/posts\/129\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/plumalia.eu\/index.php?rest_route=\/wp\/v2\/media\/128"}],"wp:attachment":[{"href":"https:\/\/plumalia.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=129"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/plumalia.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=129"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/plumalia.eu\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=129"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
