Fungal Diversity<br />

obovate, thick-walled, bitunicate and evanescent, and<br />

ascospores are globose, simple, dark brown to black (based<br />

on the type specimen of R. insignis) (Hawksworth and<br />

Booth 1974). Based on these characters, R. insignis was<br />

treated as a species of Zopfia (as Z. insignis (Petr.) D.<br />

Hawksw. & C. Booth). Rechingeriella has been assigned to<br />

Botryosphaeriaceae by von Arx and Müller (1975). Further<br />

study should be conducted on the type specimen of R.<br />

insignis in order to clarify its taxonomic status and fresh<br />

collections are needed for epitypification.<br />

Rhytidiella Zalasky, Can. J. Bot. 46: 1383 (1968).<br />

Type species: Rhytidiella moriformis Zalasky, Can. J. Bot.<br />

46: 1383 (1968).<br />

Rhytidiella was introduced based on R. moriformis, which<br />

causes perennial rough-bark of Populus balsamifera<br />

(Zalasky 1968), and produces macroconidia belonging to<br />

Phaeoseptoria. Subsequently, three more species were<br />

introduced, viz. R. baranyayi A. Funk & Zalasky, R. hebes<br />

P.R. Johnst. and R. beloniza (Stirt.) M.B. Aguirre (Aguirre-<br />

Hudson 1991; Funk and Zalasky 1975;Johnston2007), Both<br />

R. baranyayi and R. hebes seem closely related to R.<br />

moriformis on both biology and morphology (Funk and<br />

Zalasky 1975;Johnston2007), but R. beloniza is saprobic on<br />

Cordyline australis bark (Aguirre-Hudson 1991). Rhytidiella<br />

was temporarily assigned to Cucurbitariaceae (Barr 1987b).<br />

Richonia Boud., Revue mycol., Toulouse 7: 224 (1885).<br />

Type species: Richonia variospora Boud., Revue mycol.,<br />

Toulouse 7: 265 (1885).<br />

Richonia is characterized by its 1-septate, relatively large<br />

ascospores which are broadly rounded at both ends, and<br />

have a thick ornamented undulating sheath giving an<br />

irregularly ridged appearance to mature spores (Hawksworth<br />

1979). Richonia variospora has been isolated from several<br />

localities in France, but it is rare (Hawksworth 1979).<br />

Richonia was assigned under Zopfiaceae (von Arx and<br />

Müller 1975; Hawksworth1979), and there are presently no<br />

better suggestions for its familial placement. The taxon needs<br />

recollecting and epitypifying.<br />

Rimora Kohlm., Volkm.-Kohlm., Suetrong, Sakay. & E.B.<br />

G. Jones, Stud. Mycol. 64: 166 (2009).<br />

Type species: Rimora mangrovei (Kohlm. & Vittal)<br />

Kohlm., Volkm.-Kohlm., Suetrong, Sakay. & E.B.G. Jones,<br />

Stud. Mycol. 64: 166 (2009).<br />

≡ Lophiostoma mangrovei Kohlm. & Vittal [as ‘mangrovis’],<br />

Mycologia 78: 487 (1986).<br />

Rimora was introduced based on a marine fungus R.<br />

mangrovei (syn. Lophiostoma mangrovei), and is characterized<br />

by its erumpent ascomata with elongated flat tops,<br />

cellular pseudoparaphyses and cylindrical asci (Suetrong et<br />

al. 2009). Ascospores are fusoid, hyaline, 3-septate and<br />

surrounded with an evanescent sheath (Kohlmeyer and<br />

Vittal 1986; Suetrong et al. 2009). Rimora forms a robust<br />

clade with other marine fungi, such as species of Aigialus<br />

and Ascocratera, and a new family, Aigialaceae was<br />

introduced to accommodate them (Suetrong et al. 2009).<br />

Roussoellopsis I. Hino & Katum., J. Jap. Bot. 40: 86 (1965).<br />

Type species: Roussoellopsis japonica (I. Hino & Katum.)<br />

I. Hino & Katum., J. Jap. Bot. 40: 86 (1965).<br />

≡ Didymosphaeria japonica I. Hino & Katum., Bulletin<br />

of the Faculty of Agriculture, Yamaguchi University 5: 229<br />

(1954).<br />

Roussoellopsis was introduced by Hino and Katumoto<br />

(1965) based on three bambusicolous fungal species, i.e. R.<br />

japonica, R. macrospora (I. Hino & Katum.) I. Hino &<br />

Katum. and R. tosaensis (I. Hino & Katum.) I. Hino &<br />

Katum. These three species have immersed and gregarious<br />

ascomata, clavate to cylindro-clavate asci, numerous and<br />

filliform pseudoparaphyses, and 1-septate, asymmetrical<br />

ascospores (Hino and Katumoto 1965). All these characters<br />

point Roussoellopsis to <strong>Pleosporales</strong>, but its familial<br />

placement cannot be determined.<br />

Saccothecium Fr., Fl. Scan.: 349 (1836).<br />

Type species: Saccothecium sepincola (Fr.) Fr. [as ‘saepincola’],<br />

Summa veg. Scand., Section Post. (Stockholm): 398<br />

(1849).<br />

≡ Sphaeria sepincola Fr. [as ‘saepincola’], Observ.<br />

mycol. (Havniae) 1: 181 (1815).<br />

Saccothecium is characterized by its subglobose, immersed<br />

to erumpent ascomata, absence of pseudoparaphyses<br />

and hyaline, muriform to phragmosporous ascospores. It has<br />

been assigned to the Dothioraceae (Barr 1987b; Müllerand<br />

von Arx 1950). Molecular phylogenetic analysis indicated<br />

that a strain named S. sepincola nested within Didymellaceae<br />

(Schoch et al. 2009; Plate 1). The generic type needs<br />

recollecting, redescribing and epitypifying.<br />

Setosphaeria K.J. Leonard & Suggs, Mycologia 66: 294<br />

(1974).<br />

Type species: Setosphaeria turcica (Luttr.) K.J. Leonard &<br />

Suggs, Mycologia 66: 295 (1974).<br />

≡ Trichometasphaeria turcica Luttr., Phytopathology 48:<br />

282 (1958).<br />

Setosphaeria was segregated from Keissleriella on the<br />

basis of lacking a clypeus, lysigenous development of the<br />

ostiole, occurrence of setae on the perithecial wall, the<br />

absence of periphyses in the ostiole, and the hyphomycetous<br />

conidial states, and four species were included, i.e. S.<br />

prolata, S. holmii, S. pedicellata (R.R. Nelson) K.J.<br />

Leonard & Suggs and S. turcica (Leonard and Suggs<br />

1974). Currently, nine species are included in Setosphaeria<br />

(http://www.mycobank.org, Jan/2011). Setosphaeria
