Frantisekia fissiliformis

Frantisekia fissiliformis (Pilát) Spirin & Zmitr. 2007, in Spirin & Zmitrovich, Czech Mycology. 59, 144 (2007)

Basionym: Poria fissiliformis Pilát, Stud. Bot. ńĆechica 3: 1, 1940.

Diagnosis: Basidiocarps annual, resupinate, widely effused (up to 10 cm in widest dimension), sometimes fusing together. Margin floccose, whitish, later pale ochraceous, often indistinct. Pore surface even, at first yellowish, later ochraceous to brownish; pores roundish to angular, clearly shrinking after drying, with thin entire or minutely lacerate edges, (7–)810 per mm. Section: subiculum fleshy, fragile when dry, whitish to ochraceous, indistinct, up to 0.3 mm thick; tubes first fleshy, yellowish to pale ochraceous, later fragile, strongly agglutinated, ochraceous to brownish, 17 mm thick (up to 15 mm thick according to Piláts description). Hyphal structure pseudodimitic in both subiculum and tubes; generative hyphae with clamp connections, inamyloid. Subicular hyphae thick-walled (wall up to 2 μm thick); generative hyphae hyaline, 35 μm in diam., acyanophilous, pseudoskeletal hyphae hyaline, with rare simple septa, 3.56 μm in diam., cyanophilous (reaction weak but clear). Tramal hyphae subparallel. Generative hyphae dominating, thinor slightly thick-walled, yellowish, 24 μm in diam., acyanophilous; pseudoskeletal hyphae present in mature basidiocarps, scattered, thick-walled (walls up to 1 μm wide), yellowish, even or irregularly inflated, 2.55.5 μm in diam., acyanophilous. Cystidia absent, rhomboid or amorphous crystal clusters present. Basidia narrowly clavate, four-spored, clamped, 1015 × 34 μm. Basidiospores oblong-ellipsoid to short-cylindrical, thin-walled, (3.0–)3.14.0(–4.2) × (1.6–)1.72.0(–2.1) μm, with occasional oil-drops, unchanging in Melzers reagent, acyanophilous
