“…Fungal cultures from aberrant sclerotia from Upernavik, West Greenland, had feather-like mycelia when grown on PDA at 4 °C ( Figure 2 A), which were typical physiological reactions of T. hyperborea [ 23 ], and our strain did not react when paired with both tester monokaryons of T. ishikariensis var. ishikariensis and T. canadensis .…”

“…ishikariensis on PDA were dark brown (19 bay) as the same color with field samples ( Figure 1 D,E). However, the normal stems of both fungi were white (2 B) to pale yellow (6 E) or pale brown (30 clay pink) [ 23 ]. Collected stem-like structures of T. hyperborea from Upernavik, West Greenland, were gradually connected with aberrant sclerotia ( Figure 1 F), and similar findings were reported at the base of the stem of Typhula sclerotioides (Pers.)…”

“…In 1999, T. hyperborea OUP1811 was collected in Nuuk (64.1666, −57.7500) in West Greenland [ 23 ]. This strain also showed different culture morphology on PDA plates among the stains of T. hyperborea ( Figure 2 C).…”

“…This strain also showed different culture morphology on PDA plates among the stains of T. hyperborea ( Figure 2 C). This strain had weak pathogenicity against the host [ 23 ], and they showed normal growth at 4–10 °C and abundant aerial mycelia without sclerotia on PDA. Sclerotium formation was, however, observed on oatmeal agar plates ( Figure 2 D).…”

“…Maximal growth temperatures were 15, 25, and 30 °C, respectively. The mycelial growth range of T. hyperborea in Upernavik, West Greenland, was psyhrophilic and typical of this fungus [ 23 ]. According to the ranges of their mycelial growth temperatures, Typhula sp.…”

Typhulaceae Jülich is one of the cold-adapted fungal families in basidiomycetes. The representative genera, Typhula (Pers.) Fr. and Pistillaria Fr., are distinguished by the discontinuity between stems and hymenia in the former and the continuity in the latter (Fries 1821). This taxonomic criterion is ambiguous, and consequently, the view of Karsten (1882) has been widely accepted: Typhula develops basidiomata from sclerotia, while basidiomata develop directly from substrata in Pistillaris. However, Corner (1970) observed basidiomata of Pistillaria petasitis S. Imai developing from sclerotia in Hokkaido, Japan. We later recognized that P. petasitis basidiomata also emerged directly from substrates on the ground in Hokkaido. An aberrant form of Typhula hyperborea H. Ekstr. was found in Upernavik, West Greenland. This specimen had a stem-like structure on a Poaceae plant, and sclerotia developed on its tip. Similar phenomena were found in other Typhula species in Japan. In this study, we aimed to elucidate the life cycle plasticity in the genera Typhula and Pistillaria through the interactions between their ecophysiological potential and environmental conditions in their localities. We collected and prepared strains of the above fungi from sclerotia or basidiomata, and we elucidated the taxonomical relationship and determined the physiological characteristics of our strains. Our findings imply that both Typhula and Pistillaria have the potential to produce sclerotia as well as the capacity for mycelial growth at ambient air temperatures in each locality where samples were collected. These findings suggest that Typhula spp. develope basidiomata not only from the sclerotia dispersed by the basidiospores but also from mycelia generated by the spore germination, which formed basidiomata multiple times, depending on their growth environments.

Typhulaceae Jülich is one of the cold-adapted fungal families in basidiomycetes. Typhula (Pers.) Fr. and Pistillaria Fr. representing the family are distinguished from the morphology of a stipe to a hymenium (Fries 1821). The hymenium of Typhula is distinguishable from the stipe, but indistinguishable and consecutive in the genus Pistillaria. This taxonomic criterion is ambiguous, and consequently the opinion of Karsten (1882) has been widely accepted; I the genus Typhula, basidiomata develop from sclerotia, while basidiomata develop directly from substrata in the genus Pistillaris. But, Corner (1970) observed basidiomata of Pistillaria petasitis S. Imai in Hokkaido, Japan, from sclerotia. We collected irregular sclerotia of Typhula hyperborea H. Ekstr. from Upernavik, West Greenland. This specimen had a stipe-like structure on a Poaceae plant, and sclerotia developed on its tip. In August, P. petasitis in Hokkaido, Japan, formed basidiomata directly from substrates on the ground. Similar phenomena were found from other Typhula spp. in Japan. All of these fungi had the potential to produce sclerotia in culture, and as well as the capacity of mycelial growth at ambient air temperatures in each locality when samples were collected. These findings suggest that Typhula spp. developed basidiomata not only from the sclerotia dispersed by the basidiospores but also mycelia generated by the spore germination formed basidiomata multiple times depending on their growth environments.
