Ostiole centric, comprising hyaline cells. Peridium 20–30 µm thick near the ostiole, 10–25 µm wide at the sides and 10–20 µm thick at the base, 3–4 - layered, outer layer made up of thick-walled, brown cells of textura angularis; inner layer made up of thin-walled, pale brown to hyaline cells of textura angularis.

While there was no base pair (bp) difference among the three strains of A. quisqualis (Chillan, BRIP 72107 and CBS 133.32) and MFLU 23-0142 vis-à-vis the ITS sequence (based on the aligned untrimmed dataset, including gaps), 1.2 % (6 / 518 bp) difference between A. quisqualis (AMP) and strain MFLU 23-0142 was observed. Similarly, there was 0.1 % bp (1 / 876 bp) difference between A. quisqualis (CBS 133.32) and MFLU 23-0142 with regards to the LSU sequence (no LSU sequence data are available for strains AMP, Chillan, and BRIP 72107 in GenBank). A morphological comparison could not be made since our strain was collected in its sexual morph while Ampelomyces has so far been reported in its asexual morph. Therefore, the strain MFLU 23-0142 is described as the sexual morph of A. quisqualis based on phylogenetic support.</p></div>	https://treatment.plazi.org/id/D4B15DF20BA75B87B5E4D7FE19F7F7B5	Public Domain	No known copyright restrictions apply.

(2015) conducted a revision of the Massarineae, Inflatispora pseudostromatica clustered with Monodictys capensis (now synonymized to Pleomonodictys capensis, Hernández-Restrepo et al. 2017) in a clade which was considered as incertae sedis. When the second taxon, I. caryotae was introduced, it was sister to I. pseudostromatica, and together both species clustered with M. capensis and Asteromassaria pulchra (fig. 39 in Tibpromma et al. 2017). None of these taxa had any familial placement and thus, Inflatispora was referred to Massarineae incertae sedis (Tibpromma et al. 2017). At the same time, in the phylogenetic analyses conducted by Hernández-Restrepo et al. (2017), Inflatispora ( I. pseudostromatica) grouped with taxa of the novel genus Pleomonodictys ( Pleomonodictys capensis and Pl. descalsii) described in that study, and those of Bactrodesmium ( B. cubense), Clypeoloculus ( C. akitaensis) and Morosphaeria ( M. velatispora). However, Pleomonodictys was placed in the new family Pleomonodictydaceae, while the other genera were reported as incertae sedis (Hernández-Restrepo et al. 2017). Later, when Jayasiri et al. (2019) introduced Pleohelicoon in Pleomonodictydaceae, Inflatispora clustered with Pleohelicoon and Pleomonodictys in a clade, where it formed a distinct basal lineage to the two genera with low statistical support and was still considered as incertae sedis taxon. In the present study Inflatispora clusters in Pleomonodictydaceae with 99 % ML BS, 1.00 BYPP statistical support (Fig. 1). Inflatispora resembles (in its sexual morph) Robiniigena hyalinospora gen. et sp. nov. in Pleomonodictydaceae and is accepted in the family based on morpho-phylogenetic evidence.</p></div>	https://treatment.plazi.org/id/878D97D6F4A250B1B116C9EE2861D8F8	Public Domain	No known copyright restrictions apply.

Nucleotide comparison of LSU and tef 1 - α revealed 0.1 % (1 / 911 bp) and 1.3 % (12 / 921 bp) differences between the two strains (MFLU 23-0143 and GZCC 16-0102), indicating insufficient phylogenetic differences to separate them as two different taxa (Jeewon and Hyde 2016; Maharachchikumbura et al. 2021). The two strains are also morphologically similar with ostiolate and papillate, immersed ascomata, long cylindrical and short-pedicellate asci, and ascospores that are fusiform, guttulate, and 3 - septate. Therefore, strain MFLU 23-0143 is identified as M. maolanensis based on morphological and phylogenetic evidence. The main morphological difference between the two strains is the presence of a mucilaginous sheath around the ascospores of M. maolanensis MFLU 23-0143, while no such report was made for the strain GZCC 16-0102 (Zhang et al. 2017). Variations in the size of the morphological characteristics between the two strains may be accounted for by environmental differences. Zhang et al. (2017) reported M. maolanensis from an undetermined tree branch in China. The same taxon is reported here from dead stems of Chromolaena odorata in Thailand.</p></div>	https://treatment.plazi.org/id/69FA93C3C9465FD480B82D1970430332	Public Domain	No known copyright restrictions apply.

There was 0.2 % (2 / 986 bp) nucleotide difference in SSU, while 0.9 % (8 / 872 bp) in LSU and 0.1 % (1 / 894 bp) in tef 1 - α between strain MFLUCC 23-0086 and the type strain (CGMCC 3.20619) of M. oleae . Isolate MFLUCC 23-0086 is morphologically similar to M. oleae in terms of ascomata which appear as cone-shaped on the host surface, filiform and unbranched pseudoparaphyses, cylindrical, pedicellate asci and uniseriate, fusiform, 3 - septate ascospores. However, the asci and ascospore sizes of the type of M. oleae are larger than our collection. Furthermore, the peridium of strain MFLUCC 23-0086 is observed as comprising thick-walled, brown cells of textura angularis to textura epidermoidea in the outer region and compressed, hyaline cells in the innermost region (Fig. 7). The type of M. oleae is reported to have a peridium with an outer thick, carbonaceous layer and the inner one made up of 5–6 layers of hyaline cells of textura angularis to textura prismatica (Li et al. 2022). Despite these morphological differences, MFLUCC 23-0086 is recognized as M. oleae as there is insufficient genetic variation to distinguish it as a different species (Maharachchikumbura et al. 2021; Pem et al. 2021). Furthermore, the morphological differences may be due to different hosts and environmental conditions. Therefore, M. oleae is herein introduced as a new record from Duranta erecta in Thailand.</p></div>	https://treatment.plazi.org/id/A94CF02EE84854B29E07E9AF65738BB4	Public Domain	No known copyright restrictions apply.

Peridium 30–50 µm thick near the apex, 20–35 µm wide at the sides and base, comprising two regions; outer region multi-layered, composed of brown to dark brown, thick-walled cells of textura angularis, fusing and becoming indistinguishable from the pseudostroma or host cells towards the outermost side; inner layer made up of lightly pigmented to hyaline cells merging with the pseudoparaphyses. Pseudoparaphyses 1.5–2.5 µm wide, numerous, filiform, cellular, branched, indistinctly septate, usually guttulate, surrounding the asci and along the innermost layer of the peridium. Asci 80–145 (– 160) × 15–25 µm (x – = 111.5 × 20.9 µm, n = 15), bitunicate, fissitunicate, 8 - spored, hyaline, clavate to cylindric-clavate, straight to slightly curved, thin-walled, short-pedicellate, apically rounded, with an ocular chamber. Ascospores (25 –) 30–40 (– 45) × 6–10 (– 12) µm (x – = 36.8 × 8.6 µm, n = 55), overlapping 1–2 - seriate, hyaline, narrow to broadly fusiform, straight to slightly curved, 1 - euseptate, constricted at the septum, symmetrical or upper cell slightly longer than lower cell, wider upper cell, broad to acute and conically rounded at both ends, smooth-walled, sometimes guttulate, surrounded by a thick or spreading mucilaginous sheath when mature.

The ascomata of R. hyalinospora are however, coriaceous and occur in a pseudostroma mainly when they are aggregated, while the ascomata of I. pseudostromatica are hard and form under a black pseudostroma both when the ascomata are solitary or occur in groups (Zhang et al. 2011). Furthermore, R. hyalinospora has narrow to broadly fusiform, 1 - euseptate ascospores with conically rounded ends, whereas I. pseudostromatica comprises narrowly fusiform to nearly cylindrical, 3 - septate ascospores with broadly or narrowly rounded ends (Zhang et al. 2011).</p><p>Robiniigena hyalinospora is similar to I. caryotae, in terms of 1 - (eu) septate ascospores with a constricted middle septum and surrounded by a mucilaginous sheath (Tibpromma et al. 2017). However, I. caryotae has immersed ascomata while R. hyalinospora has immersed or erumpent ascomata, and the ascospores of I. caryotae are narrowly fusiform with acute ends while those of R. hyalinospora are narrow to broadly fusiform, with comparatively broader and conically rounded ends. Robiniigena hyalinospora, I. caryotae and I. pseudostromatica, are the only taxa in Pleomonodictydaceae with known sexual morphs.</p></div>	https://treatment.plazi.org/id/07660425D9735A8C8449595ECB2FB2BA	Public Domain	No known copyright restrictions apply.
