Cribraria gothica Sadykov , sp. nov.
MycoBank: MB 847868
Etymology:— as a cultural and architectural style, that excludes bright colours and asymmetric shapes.
Holotype:— The west of republican protected natural area “Russian-German Switzerland ”, on bank of Kazanka river , Kazan, Republic of Tatarstan, Russia, 55.802587°N, 49.157835°E. On sample of dead wood of Salix sp. , appeared on 220 th day, substrate collected 11 GoogleMaps Oct. 2021 by Ruslan Sadykov (RS900130).
Stalks long, fibrous, about 2.5 mm high, 30–40 µm wide ( Fig. 2A View FIGURE 2 ). Mostly dark grey, black to middle, creamy or light ochre about 100 µm from the sporocyst ( Fig. 2B–D View FIGURE 2 ). Sporocysts spherical or ellipsoidal, approximately 300 µm in height, 350 µm in diameter and 1100 µm circumference ( Fig. 2B–E View FIGURE 2 ). Peridium calycle monotone, glossy, plumbeous coloured, with barely visible parallel stripes, composed by granular material intertwined with the finest threads ( Fig. 2I View FIGURE 2 ). Edge flat, highlighted with a clear shaded ring, smooth transition to peridial net absent ( Fig. 2E, I View FIGURE 2 ). Peridium net well developed, checkmate-symmetrical ( Fig. 2E View FIGURE 2 ). Net nodes thickened, composed of small granular material (to 1 µm for granule), colour is analogical to calycle, as sharp-angled triangles and rhomboids ( Fig. 2H View FIGURE 2 ), that takes about 30% of net. Net threads thin, barely noticeable ( Fig. 2H View FIGURE 2 ). Medium ratio of net nodes length to net threads length is 1:0.25. Medium ratio of calycle square to peridium net square is 1:1.35. Medium ratio of sporocyst length to stalk length is 1:8.3. Spores rounded, grey in mass, light grey or colorless in transmitted light (TL), decorated with dense small warts, (4.5–)5–5.3(–5.7) µm in diameter (n = 30) ( Fig. 2F, G View FIGURE 2 ).
Macrohabitat:— ( Fig. 3A View FIGURE 3 ), water covered river bank with Salix spp. and Phragmites australis .
Microhabitat:— ( Fig. 3B View FIGURE 3 ), in mcc, on dead wood of Salix sp.
Distribution:— Samples of C. gothica are known only from Kazan city.
The differences between C. gothica and two similar species are listed in Table 1 View TABLE 1 .
