On MEA surface pale olivaceous grey, reverse olivaceous grey. On PDA surface and reverse olivaceous grey. On OA surface olivaceous grey. Notes -Members of the genus Paraphoma have a wide geographic distribution, and include primary and secondary pathogens of agricultural crops  (Moslemi et al. 2016). Paraphoma rhaphiolepidis is phylogenetically related, but distinct from P. chrysanthemicola (GenBank KF251165; Identities = 524/536 (98 %), 4 gaps (0 %)), a stem and root pathogen of Chrysanthemum  (De Gruyter et al. 2010). The protein-coding sequences did not reveal any highly similar sequences in the NCBIs GenBank nucleotide database.
-Crous et al. (2007a -Crous et al. ( , c, 2009a, b) , b)  showed that Readeriella resides in the Teratosphaeriaceae, having Nothostrasseria and Cibiessia synasexual morphs. Readeriella ellipsoidea is phylogenetically related to R. dimorphospora  (Crous et al. 2007c) , though only the Readeriella morph was observed in culture. Based on a megablast search using the ITS sequence, the best match was to R. dimorphospora (GenBank KF901544; Identities = 477/481 (99 %), 2 gaps (0 %)), followed by R. nontingens (GenBank EF394847; Identities = 540/545 (99 %), 1 gap (0 %)). Based on both tef1 and tub2, R. ellipsoidea was less than 85 % identical to R. dimorphospora  (GenBank KF903252 and KF902956, respectively).
On MEA surface dark mouse grey, reverse mouse grey. On PDA surface violaceous black, reverse dark mouse grey. On OA surface olivaceous grey. Notes -Quaedvlieg et al. (2014)  introduced Myrtapenidiella to accommodate penidiella-like genera occurring on Myrtaceae. Myrtapenidiella eucalyptigena is phylogenetically closely related to M. tenuiramis (conidia (6-)8-10(-12) × 3-4 μm;  Crous et al. 2009a ) and T. corymbiae (conidia 7-9(-12. 5) × 2. 5-3(-3. 5) μm;  Cheewangkoon et al. 2009 ), but is distinct in having larger conidia. Based on a megablast search using the ITS sequence, the best match was M. tenuiramis (GenBank NR_145118; Identities = 476/482 (99 %), 4 gaps (0 %)), followed by M. corymbia (GenBank NR_145115; Identities = 470/482 (98 %), 4 gaps (0 %)). Based on both tef1 and tub2, the closest matches in the NCBIs GenBank nucleotide database are equal to or less than 90 % similar.

On MEA surface and reverse olivaceous grey. On PDA surface olivaceous grey with patches of pale olivaceous grey, reverse olivaceous grey. On OA surface olivaceous grey. Notes -Myrtapenidiella balenae is phylogenetically closely related to M. tenuiramis (on E. tenuiramis, Tasmania; conidia (6-)8-10(-12) × 3-4 μm;  Crous et al. 2009a ), but morphologically distinct in having larger conidia, (13-)15-17(-18) × (3-)4 μm. Based on a megablast search using the ITS sequence, the best match was M. tenuiramis (GenBank NR_145118; Identities = 474/482 (98 %), 2 gaps (0 %)), followed by M. corymbia (GenBank NR_145115; Identities = 472/482 (98 %), 2 gaps (0 %)).
Based on a megablast search using the ITS sequence, the best match was to Mycosphaerella pseudovespa (GenBank NR_137548; Identities = 501/507 (99 %), no gaps), followed by Periconiella velutina (GenBank EU041781; Identities = 526/547 (96 %), 1 gap (0 %)). Based on the actA sequence, Z. commune was only 95 % similar to Mycosphaerella pseudovespa (GenBank KF903535; Identities = 502/531 (95 %), 10 gaps (1 %)). Fungal Planet 579 -20 June 2017 Zasmidium podocarpi  Crous, sp. nov. Etymology. Name refers to Podocarpus, the host genus from which this fungus was collected. Classification -Mycosphaerellaceae, Capnodiales, Dothideomycetes. Conidiophores solitary on underside of leaves (litter), erect, flexuous, dark brown, thick-walled, multiseptate, subcylindrical, verruculose to warty, branching in upper third of conidiophore, 200-300 × 9 -12 μm; with 1-3 lateral branches, 1-3-septate, 40-70 μm long.
Notes -Zasmidium podocarpi represents a morphologically distinct species of Zasmidium that occurs on leaves of Podocarpus. At the time of collection, these leaves displayed prominent red leaf spots (devoid of fungal sporocarps). There was no evidence to link the disease to Z. podocarpi, as sporulation was observed only on the leaf litter. This suggests that Z. podocarpi is an endophyte, which is a common character trait for species of Zasmidium (see  Huang et al. 2015). Further collections would be required to resolve the ecology of this fungus. Based on a megablast search using the ITS sequence, the best match was to Mycosphaerella pseudovespa (GenBank NR_137548; Identities = 497/509 (98 %), no gaps), followed by Periconiella velutina (GenBank EU041781; Identities = 525/548 (96 %), 3 gaps (0 %)).

It differs 3 nucleotides on ITS and is 89 % similar on tef1 and 94 % similar on tub2). Based on a megablast search using the ITS sequence, the best match was to M. tenuiramis (GenBank NR_145118; Identities = 475/ 481 (98 %), 1 gap (0 %)), followed by M. corymbia (GenBank NR_145115; Identities = 473/481 (98 %), 1 gap (0 %)). Based on both tef1 and tub2, the closest matches in the NCBIs Gen-Bank nucleotide database were equal to or less than 93 % similar to species of Myrtapenidiella.

On MEA surface amber, reverse ochreous. On PDA surface iron-grey, reverse olivaceous grey. On OA surface olivaceous grey. Notes -The poly-and paraphyletic nature of Tiarosporella was recently addressed by  Crous et al. (2015a) , who introduced several genera to accommodate tiarosporella-like genera occurring in other families. Tiarosporella corymbiae is phylogenetically related to the type species, T. paludosa (conidia 22-45 × 4-7 μm; GenBank NR_132907; Identities = 537/559 (96 %), 9 gaps (1 %)), although it is morphologically distinct, having much smaller conidia (16 -20 × 5-7 μm). Classification -Plectosphaerellaceae, Glomerellales, Sordariomycetes. Conidiomata initially closed, brown, globose on OA, but forming sporodochia on SNA, cushion-shaped, 100 -200 μm diam, surrounded by grey-brown, verruculose setae, thick-walled, flexuous, 5 -7-septate, tapering to acutely rounded apices, 60-80 × 3 -4.

Notes -Cannon et al. (2012)  introduced the genus Lectera to accommodate two soil-borne plant pathogens associated with diseases of Fabaceae. Lectera capsicum is phylogenetically related, but distinct from L. colletotrichoides (conidia on  Medicago stem, av. 8. 35 × 2. 67 μm; on PCA and PDA, ) × 2-3 μm, av. 7. 41 × 2. 43 μm;  Cannon et al. 2012). These two species cannot be distinguished based on their conidial dimensions, and are best separated based on their DNA sequence data. Based on a megablast search using the ITS sequence, the best match was to L. colletotrichoides (GenBank JQ647428; Identities = 500/505 (99 %), 2 gaps (0 %)), followed by L. longa (GenBank NR_111715; Identities = 494/510 (97 %), 12 gaps (2 %)).

The two species are 99 % similar on ITS (GenBank NR_135975; Identities = 571/579 (99 %), no gaps) and 95 % similar on tub2 (GenBank JQ706128; Identities = 708 /742 (95 %), 12 gaps (1 %)).

Harknessia podocarpi (on Podocarpus parlatorei from Argentina) has conidia that are  17. 5-26 × 11-15 μm (Nag Raj 1993) , thus larger than those of H. communis reported here.

Classification -Teratosphaeriaceae, Capnodiales, Dothideomycetes. Mycelium 2 -3. 5 µm diam, smooth, septate, pale to medium brown. Conidia produced by fragmentation of hyphae, oblongelliptical to cylindrical, 7-21 × 2 -3. 5 µm. Culture characteristics -(in the dark at 25 °C after 14 d): Colonies on 4 % malt extract agar (MEA, pH 7) attained 25 mm diam; compact, wrinkled, surface velvety, black.
Growth optimum at pH 7 and minimum at pH 2. Growth on MEA at pH 3 was 3 mm diam. Growth at 37 °C (MEA, pH 7) was 12 mm diam. Growth in response to the acidity gradient was tested according to  Hujslová et al. (2013). Notes -Acidiella encompasses two species, A. bohemica and A. uranophila. They probably represent a single species, that has been isolated from highly acidic soil and mine water  (Hujslová et al. 2013 , Vázquez-Campos et al. 2014 , Kolařík et al. 2015). Their colonies, arthroconidia and mycelium morphology is undistinguishable from A. americana. Acidiella bohemica and A. uranophila have a growth optimum at pH 5 and exhibit growth at pH 2 in contrast to A. americana. Based on ITS sequences, A. americana is 95 % similar to A. bohemica (490/516 bp, GenBank JN713913) and A. uranophila (489/515 bp, JQ904602).
