A growing awareness of a subsurface fossil record of mostly hyphal fungi organisms stretching back through the Phanerozoic to ≈400 megaannum (Ma) and possibly earlier, provides an alternative view on hyphal development. Parallel with the emergence of hyphal fungi during Ordovician–Devonian times when plants colonized the land, which is the traditional notion of hyphal evolution, hyphae‐based fungi existed in the deep biosphere. New insights suggest that the fundamental functions of hyphae may have evolved in response to an ancient subsurface endolithic life style and might have been in place before the colonization of land. To address the gaps in the current understanding of hyphal evolution a strategy based on research prospects involving investigations of uncharted geological material, new diagnostics, and comparisons to live species is proposed.

菌丝进化的一种隐秘选择

人们对地下细菌化石记录的认识不断提高,这种细菌化石细菌可以通过生代时代一直延伸到≈400megaannum(Ma)甚至更早,这为菌丝发育提供了另一种观点。当植物在土地上定殖时,与奥陶纪-德文郡时期的菌丝真菌的出现平行,这是菌丝进化的传统观念,在深部生物圈中存在基于菌丝的真菌。新的见解表明,菌丝的基本功能可能是对古老的地下内生石器时代生活方式的响应而演变的,并且可能在土地殖民之前就已经存在。为了解决当前对菌丝进化的了解方面的空白,提出了一种基于研究前景的策略,其中涉及对未知领域的地质材料进行调查,新的诊断方法以及与活体物种的比较。
