Diaporthe thailandica differs from  D. raonikayaporum in its conidiomata (500–700 × 300–600 µm vs. 110–200 × 50–130 μm), conidiophores (10–29.5 × 1.3–2.5 μm vs. 16–26 × 2–3 μm), conidiogenous cells (2.1–8.1 × 1–2.3 μm vs. 5–10 × 2–3 μm), and beta conidia (8.5–18.5 vs. 7–13 μm) (Gomes et al. 2013).  Diaporthe thailandica differs from  D. raonikayaporum (=  D. neoraonikayaporum MFLUCC 14–1133) in its conidiomata (500–700 × 300–600 µm vs. 690–1190 × 805–1285 μm), conidiophores (10–29.5 μm vs. 15–23 μm), alpha conidia (5.3–8.8 × 2.3–3.5 μm vs. 4–6 × 2–3 μm), and beta conidia (8.5–18.5 μm vs. 13–21 μm) (Doilom et al. 2017). Gamma conidia was observed in  D. raonikayaporum (=  D. neoraonikayaporum) but not in  D. thailandica (Doilom et al. 2017).  Diaporthe thailandica further differs from  D. raonikayaporum, which has only been reported as an asexual morph (Gomes et al. 2013; Doilom et al. 2017). Our strain differs significantly (&gt; 2.5 %) compared to the sequence data of  D. raonikayaporum (Table 3). However, our isolate does not have cal sequence data, while his 3 sequence data is not available for  D. raonikayaporum (MFLUCC 14–1133 and MFLUCC 14–1136). A pairwise homoplasy index showed Φw = 1.0 when a genealogical correlation model was applied between  Diaporthe thailandica and  D. raonikayaporum (Fig. 5). Thus,  Diaporthe thailandica is reported as a new species based on morphology and molecular evidence.</p><p>- Data not available.</p></div>	https://treatment.plazi.org/id/151988418AEB533AA9CC4F5E663F7153	Public Domain	No known copyright restrictions apply.

Clypeosphaeria oleae was reported only from the asexual morph (Crous et al. 2019); thus, we could not compare the morphology between the species as we could not obtain the asexual morph of our strain, and therefore the link between them cannot be confirmed. Furthermore,  C. oleae lacks rpb 2 and tub 2 data, which is important to confirm its phylogenetic placement. Morphologically,  Occultitheca chiangraiensis fits the generic concept of  Occultitheca in having immersed ascomata, short pedicellate asci with a J +, apical ring, a long distance between the ascus apex and the uppermost ascospore, and hyaline basal cells attached to brown ascospores (Rogers and Ju 2003; Samarakoon et al. 2022). Our isolate was compared to  Occultitheca species as detailed in Table 4.  Occultitheca chiangraiensis differs from  O. rosae by having smaller ascomata (x ̄ = 290 × 324 μm vs. 370 × 385 μm), a lack of a germ slit, and possesses a thicker mucilaginous sheath compared to  O. rosae (Samarakoon et al. 2022) . Our strain differs from  O. ananasi, which has uniseriate, olive-greenish ascospores becoming 2 - seriate in the middle and thin mucilaginous sheath (Tian et al. 2024).  Occultitheca chiangraiensis was also compared to the type species  O. costaricensis as it lacks molecular data.  Occultitheca chiangraiensis differs by having 1–2 individual ascomata and ascospores with a mucilaginous sheath, while  O. costaricensis has 2–12 ascomata in a cluster and ascospores without a sheath (Rogers and Ju 2003). Additionally, some  Anthostomella species have similar characteristics in terms of ascoma, asci, and ascospores with draft cells and lack germ slits, such as  A. clypeata and  A. clypeoides, but differ in a short space of the top ascospore and the ascus apex and shape of the sheath compared to  Occultitheca species (Lu and Hyde 2000; Rogers and Ju 2003). Our strain differs by 6 % in the ITS region (30 / 482, 4 gaps), 2 % in LSU (14 / 745, 4 gaps), 15 % in rpb 2 (117 / 798, no gap), 16 % in tub 2 (120 / 754, 22 gap), and 3 % in tef 1 (31 / 915, 1 gap) sequences compared to  O. rosae (HKAS 102393). Thus,  Occultitheca chiangraiensis is reported as a new species based on morphology and phylogenetic evidence.</p><p>- Data not available.</p></div>	https://treatment.plazi.org/id/AE6F81DB48285A519EE243BE137F4892	Public Domain	No known copyright restrictions apply.
