Neohormodochis D. P. Wei & K. D. Hyde 2022, gen. nov.
No full textNeohormodochis D.P.Wei & K.D.Hyde, gen. nov. Index Fungorum number: IF559771 Faces of Fungi number: FoF12297 Etymology: The epithet refers to the close phylogenetic relationship with Hormodochis. Type species: Neohormodochis septispora D. P. Wei and K. D. Hyde, sp. nov. Saprobic on dead twigs. Sexual morph: Undetermined. Asexual morph: Conidiomata perithecial, immersed, conical to subglobose, gregarious, white-pruinose. Conidiomatal wall consisting of hyaline, intricate hyphae, encompassed with crystalline substances. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, hyaline, cylindrical, developing from hyphae of conidiomatal wall. Conidia hyaline, ellipsoidal, twocelled, occasionaly asepate, slightly curved, forming branched chains. Notes: Neohormodochis was introduced to accommodate the new species N. septispora which was found on dead twigs in Yunnan Province, China. The new species nested with Hormodochis as a sister clade. Hormodochis is known from three asexual morphic species viz. H. aggregata, H. eucalypti and H. melanochlora. All three species have non-pruinose conidiomata, non-crystalline conidiomatal wall of thin-walled, brown textura angularis, holothallic conidiogenous cells with upper cells becoming fertile, septate and disarticulating into arthroconidia. The arthroconidia are olivaceous brown, aseptate, subcylindrical to somewhat doliiform, with truncate ends (Crous et al. 2020a). However, Neohormodochis septispora produces white-pruinose conidiomata, crystalline conidiomatal wall and hyaline, holobalstic conidiogenous cells with upper cells becoming fertile and budding new conidia rather than arthroconidia. The conidia of N. septispora are hyaline, ellipsoidal, dominantly septate, slightly curved, round at both ends. Phylogenetic placement and differences on morphology of conidiomata, conidiomatal wall, and conidia as well as conidiogenesis separate our collections from Hormodochis.Published as part of Wei, De-Ping, Gentekaki, Eleni, Wanasinghe, Dhanushka N., Hyde, Kevin D., To-Anun, Chaiwat & Cheewangkoon, Ratchadawan, 2022, Neohormodochis septispora gen. et sp. nov.

Neohormodochis septispora D. P. Wei & K. D. Hyde 2022, sp. nov.
No full textNeohormodochis septispora D. P. Wei & K. D. Hyde, sp. nov. (Figure 2) Index Fungorum number: IF 559772 Faces of Fungi number: FoF12298 Etymology: The epithet “ septispora ” refers to the septate conidia. Holotype: China, Yunnan Province, Kunming, Panlong district, Kunming Institute of Botany, on an unidentified dead twig, 31 March 2021, Cuijinyi Li, KLCJY54 (HKAS 124171, holotype), (KUNCC 22-10806, ex-type culture). Saprobic on an unidentified dead twigs. Sexual morph: Undetermined. Asexual morph: Conidiomata 165–360 × 140–340 (x̄ = 282 × 252, n = 10) μm, perithecial, immersed, conical to subglobose, white-pruinose, gregarious, with olivaceous green content. Conidiomatal wall 11–30 (x̄ = 19, n = 30) μm, consisting of hyaline, intricate hyphae, being encompassed by a layer of irregularly-shaped crystals. Conidiophores reduced to conidiogenous cells. Conidiogenous cell 3.5–10 × 0.8–2.4 (x̄ = 7 × 1.6, n = 25) μm, arising from stromatic cells, hyaline, cylindrical, thin-walled, the first conidium becoming conidiogenous by apical wall-building to form connected chain. Conidia 7.6–12 × 2–3.8 (x̄ = 9.5 × 3.3, n = 40) μm, hyaline, ellipsoidal, two-celled, occasionally asepate, slightly curved, arranged in branched chain. Culture characteristics: isolates were obtained from germinating conidia. Colony slow-growing, reaching 2 cm after 8 weeks on PDA, white, circular, mycelia dense, velvety, reverse creamy-yellow.

Songhuaba reservoir, 11 December 2021, De-Ping Wei, SHB1225 (HKAS 124170), (KUNCC22-10810, living culture). Notes: Phylogenetically, Neohormodochis septispora has a sister affiliation to a clade comprising Hormodochis aggregata, H. melanochlora and H. eucalypti (Figure 1). Morphologically, N. septispora is similar with H. aggregata by catenulate conidia but differs by the hyaline, ellipsodial and septate conidia while it is olivaceous brown, subcylindrical to doliiform, and aseptate in the latter (Crous et al. 2020a). Hormodochis melanochlora is distinct by erumpent, globose, brown conidiomata that are immersed, conical to globose, white-pruinose from N. septispora (Crous et al. 2020a). Hormodochis eucalypti (syn. Phacidiella eucalypt) has dark brown to black conidiomata and subcylindrical to barrel-shaped conidia that are dramatically different from N. septispora (Crous et al. 2007, 2020b).Published as part of Wei, De-Ping, Gentekaki, Eleni, Wanasinghe, Dhanushka N., Hyde, Kevin D., To-Anun, Chaiwat & Cheewangkoon, Ratchadawan, 2022, Neohormodochis septispora gen. et sp. nov.

Phacidiella P. Karst.
No full textPhacidiella P. Karst., Hedwigia 23: 85 (1884) amended Saprobic on various plants i.e. Asteraceae (Artemisia vulgaris), Rubiaceae (Asperula asperne), Myrtaceae (Eucalyptus sp.), Podocarpaceae (Podocarpus latifolius), Salicaceae (Salix caprea, S. viminalis), and Vitaceae (Vitis vinifera) (Li et al. 2020). Sexual morph: Apothecia clustered, immersed, cupulate, opening by a finely large pore. Margin entire to lacerate, white-pruinose, turnup outward. Disc deeply immersed, yellow, splitting away from the margin when dry. Exciple, four-layered; 1) prominent accessory thalline margin, 2) wall extended from subhymenium, of hyaline, thickwalled cell of textura angularis, 3) crystalliferous layer where crystals are abundant particularly in the upper part and 4) compact periphysoidal layer that perpendicularly lined with the crystalliferous layer. Subhymenium comprised of hyaline, angular cells, J-. Paraphyses filiform, numerous, aseptate, apically branched, enlarged, circinate, J- or faintly J +, not gelatinous, as long as asci. Asci eight-spored, cylindrical, slightly tapering toward the base, thick-walled, with a thick apex. Ascus cap round, pierced by a pore. Ascospores filiform, multiseptate, flexuous, non-disarticulating, no contraction at septa. Asexual morph: see Sutton (1980) and Li et al. (2020). Type species: Phacidiella salicina P. Karst., Hedwigia 23: 85 (1884) Notes: The nomenclature and composition of Phacidiella have been subjected to multiple revisions and ultimately six asexual species remain in this genus (Smerlis 1962, Li et al. 2020). Historically, the sexual morph of Phacidiella has been linked to Phacidiopycnis (syn. Potebniamyces) (Smerlis 1962, Johnston et al. 2014) and Pyrenopeziza (Sutton 1980), but these connections have not been verified by cultures and molecular data. Potebniamyces is characterized by ellipsoidal to globose, carbonaceous apothecia, cylindrical asci and guttulate, aseptate, ellipsoidal-fusoid ascospores. Pyrenopeziza is a speciose genus, containing more than 300 epithets, while the comprehensive taxonomic analysis of this genus is lacking (Crous et al. 2017). Pyrenopeziza was featured with blackish, cupulate, hairy apothecia, cylindricalclavate asci, aseptate, ellipsoidal-clavate ascospores (Fuckel 1870). In this study, we have obtained a collection from China, which was isolated from its sexual morph. In the DNA-based sequence data analyses of combined ITS, LSU, mtSSU and rpb2 sequences, the new taxon forms a clade with P. alsophilae and P. podocarpi. Thus, we determine the taxonomic placement of our new taxa in this genus and amended the generic description to accommodate its sexual morphic characteristics. The ascospore morphology of our new species is filiform, multiseptate, dramatically differing from those in Phacidiopycnis and Pyrenopeziza. The findings suggest that Phacidiella is not congeneric with Phacidiopycnis and Pyrenopeziza.Published as part of Wei, De-Ping, Gentekaki, Eleni, Wanasinghe, Dhanushka N., Hyde, Kevin D., To-Anun, Chaiwat & Cheewangkoon, Ratchadawan, 2022, Taxonomy and morphology of Phacidiella kunmingensis sp. nov.
