| Remarks (internal) : | The Sporophore:s appear to be very young or immature. Maas Geesteranus (1967a) placed this species in synonymy with Sarcodon atroviridis, but later stated that it is distinct (Maas Geesteranus, 1974). Baird (1984) believed that H. bambusinum is conspecific with H. atroviridis. | |
