Mycelia Prime

巨型菌盖（Basidiomycota gigas）作为巨大的静止型初级生产者，锚定了菌丝主星（Mycelia Prime）的地下生物圈。这些高达三百米的巨大真菌塔是星球上唯一的大气水储备库，它们从地热喷口凝结水分，并将其储存在多孔且富含纤维素的菌盖内。其宽阔如伞的表面主宰着昏暗的地貌，创造出独特的微气候以维系下方低等植物群落的生存，同时通过特化的鳃状结构过滤有毒气体。 尽管无法移动，巨型菌盖却是共生编织者（Weaver）物种至关重要的结构载体。编织者错综复杂的丝质网络加固了菌柄以抵御地震变动，防止其坍塌，同时汲取宿主维管系统渗出的营养丰富的汁液。这种专性共生关系确保了整个真菌生态系统的稳定性，使这些沉默的巨人成为调节水循环并为地下生命之网提供庇护的活体堡垒。

The Spore-Sifter (*Aero-fungus volans*) drifts silently through Mycelia Prime's sub-terra canopy, its gossamer, translucent sacs billowing like living sails. These fragile structures act as delicate air filters, passively trapping excess airborne spores from the dense fungal forest below. By regulating particulate density, this species prevents catastrophic overgrowth that could suffocate the underlying mycelial networks, maintaining a precarious atmospheric equilibrium within the cavernous biosphere. Observations reveal thousands of these floating organisms moving in synchronized currents, their internal membranes glowing faintly as they digest captured nutrients. Though seemingly fragile, their collective filtering capacity is immense, processing tons of spores daily. Without the Spore-Sifter's constant vigilance, the forest would rapidly choke itself, collapsing the delicate sub-terra ecosystem into a stagnant, suffocating mass.

根碾者（Lithos-mycetoid）呈现为一簇缓慢漂流的玄武岩灰色结节，完美伪装于主菌丝体星球地下层洞穴的岩壁之中。这些碎屑食者以冰川般的耐心穿行于真菌地表，其钙化的腹面在腐烂的坠落菌盖上无声研磨。移动时，它们分泌特化的酶类溶解坚韧的几丁质与木质素，提取必需养分，同时将基质粉碎为富含矿物质的细尘。 这一审慎的循环过程对星球幽暗生物圈至关重要，它将死亡转化为肥沃土壤，滋养下一代巨型蘑菇。尽管极易被误认为惰性地质构造，但仔细检视可发现其岩石外壳内微弱的节律性搏动。根碾者确保分解的永恒循环持续运转，在深层真菌黑暗中架起有机衰变与地质更新之间的桥梁。
