Notes -Pseudoarthrographis is morphologically similar to the genus Arthrographis, which also resides in the Dothideomy cetes (Eremomycetaceae). Species of Arthrographis have been isolated from the air, compost, marine sediments, soil, wood and also from opportunistic human infections  (Giraldo et al. 2014).
Another genus to consider in this description is Arthropsis, which accommodates species with dark arthroconidia, joined by adjacent connectives and developing from undifferentiated conidiogenous hyphae  (Sigler et al. 1982). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Neodactylaria obpyriformis (GenBank NR_154267. 1; Identities = 476/571 (83 %), 29 gaps (5 %)), Hormococcus conorum (GenBank KF993412. 1; Identities = 477/577 (83 %), 33 gaps (5 %)) and Oncopodiella trigonella (GenBank KY853455. 1; Identities = 348/397 (88 %), 6 gaps (1 %)).

Classification -Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetes. Conidiomata stromatic, acervuloid, separate, superficial on agar, globose in outline, 200-350 µm diam, brown with creamy conidial mass in centre, surrounded by setae. Setae arising from basal stroma, straight to slightly curved, with basal septum, medium brown, smooth, thick-walled, unbranched, 90 -200 µm long, apex acute, 3-4 µm diam at the base. Conidiophores lining the basal stroma, cylindrical, hyaline, smooth, branched, 1-3-septate, 20 -65 × 2 -2. 5 µm. Conidiogenous cells phialidic, cylindrical, hyaline, smooth, 12 -20 × 2 -2. 5 µm.

Polynema podocarpi is the first species of the genus that has been subjected to DNA sequencing, and thus adds a new lineage to the Chaetosphae riaceae. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Pseudolachnea fraxini (GenBank NR_155628. 1; Identities = 484/536 (90 %), 29 gaps (5 %)), Pseudolachnea hispidula (GenBank AB934071. 1; Identities = 477/528 (90 %), 28 gaps (5 %)) and Pseudolachnella longiciliata (GenBank AB934081. 1; Identities = 469/528 (89 %), 29 gaps (5 %)).

Furthermore, her data also showed several other species reside in different orders, and are not congeneric with the type, A. crateriforme. The present collection, however, clusters within Acrodontium s. str. where it represents a distinct lineage, known from Metrosideros excelsa in New Zealand, clustering with another strain from New Zealand (PDD 105475) originally identified as Septoria alpicola, occurring on Fuchsia excorticata (conidia 60 × 2 µm, 1-7 septate on the specimen). It is apparent that the culture PDD 105475 became contaminated with the fungus described here as Acrodontium podocarpi, which due to its sticky, minute conidia, tends to be a common contaminant in culture collections. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to 'Septoria cf.
alpicola' (GenBank KM975402. 1; Identities = 528/532 (99 %), no gaps), Acrodontium crateriforme (GenBank GU214682. 1; Identities = 507/538 (94 %), 13 gaps (2 %)) and Acrodontium crateriforme (GenBank KX287268. 1; Identities = 507/538 (94 %), 13 gaps (2 %)). Closest hits using the LSU sequence are 'Septoria cf. alpicola' (GenBank KM975377. 1; Identities = 862/864 (99 %), no gaps), Acrodon tium crateriforme (GenBank KX286957. 1; Identities = 842/870 (97 %), 1 gap (0 %)) and Acrodontium neolitseae (GenBank KJ869184. 1; Identities = 816/844 (97 %), 1 gap (0 %)).

1 and MH327835. 1, MycoBank MB825405). Notes -Chaetopsina eucalypti is phylogenetically related to C. pini, known from needle litter of Pinus caribaea collected in Thailand  (Crous et al. 2013). The genus Chaetopsina has nectria-like sexual morphs, and although the culture examined in this study formed ascomatal initials, these did not become fertile. Some species of Chaetopsina have been reported from Eucalyptus, namely C. fulva (Hawaii; conidia 7-11 × 1 µm) and C. splendida (Australia and Brazil; conidia 9. 5 -12 × 1. 5 µm)  (Sutton & Hodges 1976 , Crous et al. 1989 ). Chaetopsina eucalypti is easily distinguished from these species based on its larger conidia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Chaetopsina pini (GenBank NR_137822.

Fungal Planet 763 -13 July 2018 Neometulocladosporiella  Crous & M. J. Wingf. , gen. nov. Etymology. Name refers to the fact that it is similar to Metulocladosporiella. Classification -Rutstroemiaceae, Helotiales, Leotiomycetes. Conidiophores dimorphic. Microconidiophores erect, pale brown, smooth, solitary, subcylindrical, straight to flexuous, septate, giving rise to a single, terminal conidiogenous cell.
On MEA surface isabelline, reverse hazel. On PDA surface and reverse honey. On OA surface buff. Notes -Neometulocladosporiella resembles Metulocla do sporiella (Herpotrichiellaceae), a genus associated with speckle disease on banana leaves  (Crous et al. 2006 , 2014 , Marin-Felix et al. 2019). The fungus from Eucalyptus leaves is, however, phylo genetically distinct, being allied to Helotiales and clustering with genera such as Ciboria and Lanzia. A new genus, Neo metulocladosporiella, is therefore introduced to accommodate the fungus occurring on Eucalyptus, and to distinguish it from Metulocladosporiella, which occurs on Musa spp. (Bensch et al. 2012 , Marin-Felix et al. 2019). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Lanzia allantospora (GenBank AB926099.

Fungal Planet 764 -13 July 2018 Myrotheciomycetaceae  Crous, fam. nov. Classification -Myrotheciomycetaceae, Hypocreales, Sor dariomycetes. Conidiomata superficial on media, solitary conidiophores to sporodochia, with crystalline to white or orange conidial mass; with or without basal stroma.
On MEA surface ochreous, reverse luteous. On PDA surface pale luteous, reverse amber. On OA surface ochreous to saffron. Notes -Morphologically, the present collection resembles species accommodated in the Myrothecium complex. The Myro thecium generic complex was recently treated by  Lombard et al. (2016) , none of which cluster with the fungus from Co rymbia, which is allied to hypocrealean isolates identified as Trichothecium, Niesslia and Leucosphaerina. The new genus, Myrotheciomyces, is therefore introduced to accommodate the fungus occurring on Corymbia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Niesslia exilis (GenBank MG826991. 1; Identities = 552/636 (87 %), 56 gaps (8 %)), Trichothecium ovalisporum (GenBank NR_111321.

Fungal Planet 765 -13 July 2018 Eucalyptostroma eucalyptorum  Crous & M. J. Wingf. , sp. nov. Etymology. Name refers to Eucalyptus, the host genus from which this fungus was collected. Classification -Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetes. Conidiomata scattered to gregarious, consisting of dense synnemata, 100 -300 × 20 -70 µm; stem consisting of aggregated conidiophores, hyaline, smooth, 2-3 µm diam, flaring outwards in upper conidiogenous region to form a yellow-orange slimy conidial mass.
Notes -The monotypic genus Eucalyptostroma was recently introduced for a hyphomycete occurring on Eucalyptus leaves in Malaysia  (Crous et al. 2016a). Eucalyptostroma eucalyptorum which also occurs on Eucalyptus leaves, but in Colombia, is distinguished by forming more synnematal conidiomata, and having slightly larger conidia than E. eucalypti (3 -4. 5 × 2 µm). Eucalyptostroma is recognized on leaves by forming slimy, yellow-orange conidial massed on either synnemata or sporodochia.

Conidiophores solitary, erect, flexuous, unbranched, with dry conidial masses, 80 -160 × 2 -2. 5 µm, 4 -6-septate. Fertile hyphae developing in upper third of conidiophore, 2 -2. 5 µm diam, dichotomously branched, fragmenting to form long chains of up to 10 conidia in a dry conidiogenous head. Conidia thinwalled, subhyaline, subglobose to cylindrical, (2 -)3 -4(-5) × (1. 5 -)2 µm, with asperulate perispore. Culture characteristics -Colonies flat, spreading, with moderate aerial mycelium and even lobate margin, reaching 7 mm diam after 2 wk at 25 °C.
On MEA, PDA and OA surface smokegrey, reverse umber with diffuse umber pigment. Notes -The genus Oidiodendron, which commonly occurs in soil and on plant litter, was treated by  Rice & Currah (2005) , who provided keys to 23 species. Phylogenetically, O. eucalypti is related to O. truncatum, from which it can be distinguished based on its conidia. Conidia of O. truncatum are dark at maturity, barrel-shaped, truncate with distinct apical scars and reticulate ornamentation, (2-)3. 5(-5) × (1-)2. 5(-3. 5) μm  (Rice & Currah 2005).

spartinae, occurring on Spartina patens, and several other grasses) was considered by  Hernández-Restrepo et al. (2016b). Tracylla eucalypti, which lacks conidial appendages, clusters with T. aristata, which was originally described from Eucalyptus leaf litter collected in Australia  (Nag Raj 1993). By adding the present collection to the genus, we expand the circumscription of Tracylla to include taxa lacking conidial appendages. Unfortunately, cultures of T. eucalypti were sterile, and the conidiomatal development could not be fully elucidated.
