Fungi - MSN Encarta |
 | | Fungi that are intimately associated with roots of higher plants form mycorrhiza, a specialized type of hyphal growth in which a portion of the mycelium either wraps itself around the tips of roots, forming a velvety white cover, or penetrates into the cortex of the root. |
 | | The morels, truffles, and cup fungi are well-known ascomata, with asci borne at the upper surface. |
 | | Tooth fungi, Hydnaceae, have the hymenium on spiny outgrowths. |
