Asexual morph: Colonies superficial on the host substrate, effuse, hairy, dark brown. Conidiophores 200 – 350 × 10 – 12 μm wide (x ̄ = 288 × 11.5 µm, n = 10), macronematous, mononematous, solitary, arising from an inconspicuous stromatic base, straight or slightly flexuous, 2 − 4 septate, dark brown to black at base, pale brown towards apex, with spherical conidial head, slightly constricted near conidial head and knot-like near the base, smooth or slightly rough-walled. Conidiogenous cells 5 – 9 × 7 – 11 μm (x ̄ = 8 × 9 μm, n = 10), polyblastic, discrete, terminal, subglobose to ellipsoidal, light brown, located at nodose apices of conidiophores.

Culture characters: Colonies on PDA reaching 50 mm diam. after 14 days at 25 ° C, irregular with smooth margin, slightly woolly flattened mycelia, circular, cottony, hairy at the margin, white; pale yellow at the margin and mud yellow at the middle in reverse. Material examined: Thailand, Chiang Rai, Tha Sut sub district, Mueang District, on recently dead twigs of Tephrosia cinerea (L.) Pers. (Fabaceae), 28 January 2023, collected and identified by Ashani Madagammana, AD 0408 (MFLU 23 – 0453); living cultures MFLUCC 23 - 0294. Known host and distribution: Angelica sylvestris L. (Apiaceae), Conium maculatum L. (Apiaceae), Heracleum sosnowskyi Manden. (Apiaceae) in Lithuania (Markovskaja and Kačergius 2014); Ampelopsis brevipedunculata (Maxim.) Trautv. (Vitaceae), Benthamidia japonica (Siebold & Zucc.) H. Hara (Cornaceae), Prunus verecunda (Koidz.) Koehne (Rosaceae) in Japan (Tanaka et al. 2015); Celtis formosana Hayata (Cannabaceae), Macaranga tanarius (L.) Müll. Arg. (Euphorbiaceae) in Taiwan region in China (Tennakoon et al. 2021); Imperata cylindrica (L.) Raeusch. (Poaceae), Prunus armeniaca L. in China (Su et al. 2023; Yang et al. 2022); Magnolia grandiflora L. (Magnoliaceae), Peltophorum sp. (Fabaceae) in Thailand (Jayasiri et al. 2019); Mimosa diplotricha C. Wright (Fabaceae) in Thailand (Hyde et al. 2024); Vigna unguiculata (L.) Walp. (Fabaceae) in India (Jayawardena et al. 2022); Tephrosia cinerea (L.) Pers. (Fabaceae) in Thailand (this study). Notes: Based on the BLAST results, our sequences showed high similarity to different strains of P. byssoides for the ITS, LSU, SSU, tef 1 - α and rpb 2 sequences. Also, based on the phylogenetic analyses, our fungal strain (MFLUCC 23 - 0294) grouped well with the type (MFLUCC 20 - 0172) and other authentic strains (MFLUCC 19 - 0134, MFLUCC 22 - 0132, MFLUCC 20 - 0137, MFLUCC 18 - 1548, UESTCC 18 - 1548, MFLUCC 18 - 1553, MFLUCC 17 - 2292, UESTCC 22 - 0138, NCYUCC 19 - 0314) of P. byssoides (Figure 1). Morphologically, our collection (MFLU 23 - 0453) is similar to P. byssoides, which was collected from dead culms of Imperata cylindricain in China (Su et al. 2023). We identified our fungal strain (MFLUCC 23 - 0453) as P. byssoides based on morpho-molecular evidence. Previously, P. byssoides have been recorded on Magnolia grandiflora, Peltophorum species, and Mimosa diplotricha in Thailand (Jayasiri et al. 2019). Therefore, our fungal collection is the first record of P. byssoides on Tephrosia cinerea (Fabaceae).	en	Madagammana, Ashani D., Phukhamsakda, Chayanard, Bhunjun, Chitrabhanu S., Rathnayaka, Achala R., Bhat, D.

Index Fungorum number: IF 319348, Figure 4 Saprobic on Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs. Sexual morph: Undetermined. Asexual morph: Colonies on the natural substrate numerous, effuse, dark brown to black, floccose. Conidiophores 230 – 240 × 7.5 – 9.5 μm (x ̄ = 238 × 8 µm, n = 10), macronematous, mononematous, straight or slightly flexuous, branched, bifurcate, solitary or fasciculate, rarely 1 – 2 together, brown to dark brown, 3 – 7 - septate, smooth to minutely verruculose, thick-walled. Conidiogenous cells polyblastic, pale brown to brown, terminal, integrated or discrete, oval to subglobose, smooth to verruculose. Conidia 14 – 18 × 6 – 9 µm (x = 15.4 × 7 µm, n = 10), solitary, ellipsoid to obovoid, initially faint yellow or pale brown, becoming brown to dark brown at maturity, aseptate, verrucose. Culture characters: Colonies on PDA reaching 50 mm diam. after 14 days at 25 ° C, irregular with smooth margin, slightly woolly, flattened, yellow toward the middle; yellow at the margin, and yellow to brown at the middle in reverse; producing yellow pigments on PDA. Material examined: Thailand, Chiang Rai, Tha Sut sub district, Mueang district, on recently dead flowers of Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs (Poaceae) flowers, 28 January 2023, collected and identified by Ashani Madagammana, AD 0410 (MFLU 23 - 0454); living cultures MFLUCC 23 - 0295. Know hosts and distribution: Androphogon, Brachiaria, Cenchrus, Echinochloa, Heteropogon, Oryza, Panicum, Saccharum, Sorghum, and Zea (Poaceae) in Australia, Brazil, British Solomon Island Protectorate, Cuba, Ethiopia, India, Jameica, Kenya, New Guinea, Sierra Leone, Sudan Republic, Uganda, and Zambia (Ellis 1971), Imperata cylindrica (L.) Raeusch. (Poaceae) in China (Su et al. 2023), Musa sp. in Thailand (Samarakoon et al. 2024) and Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs (Poaceae) flowers in Thailand (this study). Notes: Based on the BLAST results, our sequences showed high similarity to different strains of P. echinochloae and P. imperatae for the ITS, LSU, rpb 2, and tef 1 - α sequences. However, different Periconia species showed high similarity based on SSU sequence. According to phylogenetic analyses, our isolate (MFLUCC 23 - 0295) grouped with the strain of P. echinochloae (MFLU 23 - 0228) reported in Thailand. Furthermore, both our isolate and P. echinochloae (MFLU 23 - 0228) grouped with the ex-type strain (CGMCC 3.23931) and other authentic strains (UESTCC 22.0145; UESTCC 22.0146) of P. imperatae reported in China (Figure 1). Our species was isolated from specimens collected from dead flowers of Megathyrsus maximus in Chiang Rai, Thailand. Based on conidia and conidiophore morphology as well as culture characteristics, our isolate is similar to the holotype (HKAS 126517) of P. imperatae, which was collected from dead leaves and culms of Imperata cylindrica (Poaceae) in China (Su et al. 2023). However, the lengthto-width ratio of conidia is different. Furthermore, our isolate is similar to the description of P. echinochloae provided by Ellis (1971). The morphological characters of P. echinochloae and P. imperatae are tabulated in Table 3. We identify our fungal strain as P. echinochloae based on morphology and phylogeny. However, previously, P. echinochloae were reported in Megathyrsus species (as Panicum) and also reported in Thailand. Therefore, this is the second report of P. echinochloae from Thailand.	en	Madagammana, Ashani D., Phukhamsakda, Chayanard, Bhunjun, Chitrabhanu S., Rathnayaka, Achala R., Bhat, D.
