Fungal Diversity difference could be observed, and both are described from rotting needles of conifers (Barr 1975; Batista et al. 1959; Höhnel 1918b). Morphologically, Extrawettsteinina is comparable with Kriegeriella. In particularly, E. pinastri could not be distinguished from K. transiens or K. mirabilis. Thus, K. transiens including Extrawettsteinina pinastri was treated as synonyms of K. mirabilis, andwas included in the section of Kriegeriella under the genus Kriegeriella (von Arx and Müller 1975; Barr1975). The other section of Kriegeriella, Extrawettsteinina, includes two previous Extrawettsteinina species, i.e. K. minuta and K. mediterranea. Barr(1987b) introduced a family, i.e. Kriegeriellaceae (Dothideales) to accommodate Kriegeriella and Extrawettsteinina. This proposal is rarely followed, and Kriegeriella is usually assigned to Pleosporaceae (<strong>Pleosporales</strong>) (Eriksson2006; Lumbsch and Huhndorf 2007). Phylogenetic study None. Concluding remarks Kriegeriella might belong to Microthyriaceae, although it would be unusual in this family in having 5-6-septate ascospores. Micropeltidaceae better accommodates the ascospores, however, the parallel arrangement of cells of the upper peridium are not typical. Asterinaceae may be most suitable as Luttrell (1973) suggested. Phaeotrichum Cain & M.E. Barr, Can. J. Bot. 34: 676 (1956). (Dothideomycetes, family incertae sedis, Phaeotrichaceae) Generic description Habitat terrestrial, saprobic (coprophilous). Ascomata small, cleistothecial, solitary, or in small groups, superficial, with long straight or slightly flexed, thin, black appendages evenly scattered on the surface of the ascomata, globose, black. Peridium thin, carbonaceousmembraneous, 1-layered, composed of dark brown thickwalled cells of textura angularis. Hamathecium not observed. Asci bitunicate form not clear, fissitunicate dehiscence not observed, broadly clavate, with a relatively thick pedicel. Ascospores oblong to ellipsoid, hyaline when young, turning reddish brown at maturity, 1-septate, deeply constricted at the septum, each end with a subhyaline and broadly rounded germ pore, readily forming partspores at the septum at maturity. Anamorphs reported for genus: none. Literature: Cain 1956; Malloch and Cain 1972. Type species Phaeotrichum hystricinum Cain & M.E. Barr, Can. J. Bot. 34: 677 (1956). (Fig. 103) (Some information for the following description is from Cain 1956) Ascomata 170–280 μm diam., cleistothecial, solitary, or in small groups, superficial, with 15–20 long straight or slightly flexed, thin, black appendages evenly scattered on the surface of the ascomata, 0.5–1 mm long, 15–25 μm wide at base, tapering to less than 5 μm at the blunt apex, with few or without septa, globose, black, smooth (Fig. 103a). Peridium thin, carbonaceous-membraneous, 1-layered, composed of dark brown thick-walled cells of textura angularis, cells 8–16 μm diam., cell wall 0.5–1.5 μm thick (data obtained from Cain 1956) (Fig. 103b). Hamathecium not observed. Asci 42–48× 14–17 μm, 8-spored, bitunicate form not typical, lacking fissitunicate dehiscence, broadly clavate, with a relatively thick pedicel which is about 18 μm (data obtained from Cain 1956). Ascospores 14–16×4–5 μm, 4-seriate, oblong to ellipsoid, hyaline when young, turning reddish brown at maturity, 1-septate, deeply constricted at the septum, each end with a subhyaline and broadly rounded germ pore, smooth, readily separating into partspores at the septum at maturity (Fig. 103c, d, e and f). Anamorph: none reported. Material examined: CANADA, Ontario, Muskoka, Stoneleigh, on porcupine dung, 18 Aug. 1932, Cain (TRTC 4361, holotype). Note: the ascomata of the specimen are fragile and no asci could be obtained. Notes Morphology Phaeotrichum was formally established by Cain (1956) to accommodate two new coprophilous fungi, i.e. P. hystricinum and P. circinatum Cain, and P. hystricinum was selected as the generic type. Phaeotrichum is mainly characterized by its coprophilous habitat, superficial cleistothecial ascocarps covered by long hairy appendages, reddish brown 1-septate ascospore with a broadly rounded germ pore at each end, readily breaking into partspores (Cain 1956). According to Cain (1956), Phaeotrichum possesses untypical bitunicate ascus, and the ascospore releasing is described as “simply break down and allow the contents to become free in the cavity of the ascocarp”. This ascospore releasing mechanism is considered as evolutionarily developed compared to those that “discharge the ascospores through an apical pore” (Cain 1956). Although lacking
