03BC894EFFF61D15C1F7FF30FB6EFB98.taxon	etymology	Etymology: — subrhizomorpha (Lat.), refers to the similarity to Perenniporia rhizomorpha. Diagnosis: — Perenniporia subrhizomorpha is similar to P. rhizomorpha by having cream-colored rhizomorphs and similar pores (4 – 6 per mm), but differs in its wider generative hyphae and truncated basidiospores. Holotype: — CHINA. Hebei Province: Baoding, Laishui County, Yesanpo Bailixia Scenic Spot, on fallen branch of angiosperm, 23 July 2019, Li-Wei Zhou, LWZ 20190723 - 10 (HMAS!). Description: — Basidiomes annual, resupinate, adnate, papery, soft when fresh, becoming corky upon drying. Pore surface white when fresh, cream to buff upon drying; pores angular, 4 - 6 per mm; dissepiments thin, entire. Sterile margin thinning, white, up to 2 mm wide, usually with white to cream-colored rhizomorphs. Context cream, thin, up to 0.2 mm thick. Tubes concolorous with pore surface, corky, up to 0.6 mm long. Hyphal system dimitic; generative hyphae with clamp connections, slightly cyanophilous; skeletal hyphae cyanophilous; tissue unchanged in KOH. Generative hyphae in context infrequent, difficult to find, hyaline, thin-walled, unbranched, 4 – 5 μm diam, usually encrusted with crystals; skeletal hyphae in context dominant, hyaline, thick-walled with a distinct lumen, branched, interwoven, 3 – 4 μm diam. Generative hyphae in trama infrequent, difficult to find, hyaline, thin-walled, unbranched, 3.5 – 4.5 μm diam; skeletal hyphae in trama dominant, hyaline, thick-walled with a distinct lumen, branched, interwoven, 2 – 3 μm wide. Dendrohyphidia present at the dissepiments. Cystidia and cystidioles absent. Basidia clavate, with four sterigmata and a basal clamp connection, 17 – 20 × 9 – 10 μm; basidioles in shape similar to basidia but slightly smaller. Basidiospores ellipsoid to broadly ellipsoid, truncate, hyaline, thick-walled, smooth, dextrinoid, cyanophilous, (5.6 –) 5.7 – 6.5 (– 7.6) × (4.2 –) 4.3 – 5.5 (– 5.8) μm, L = 6.2 μm, W = 4.8 μm, Q = 1.26 – 1.29 (n = 60 / 2).
