Mycorrhizal systems in few samples monopodial-pyramidal, mostly unramified; mycorrhizal ends loosely long-spiny especially in the distal part, older mycorrhizae seem to loose cystidia, amber, very tips light amber, older parts amber to dark brown; outer mantle layers in plan view with epidermoid to elongated rectangular cells; cystidia ramified with recto-like angle, distally bent, septa 20-40 um distant; in cross-section Hartig net 1 cortical cell layer (epidermis) deep. |
