Cantharomyces papillatus Santamaria & Pedersen 2021, sp. nov.
No full textCantharomyces papillatus Santam. sp. nov. MB#840595 Fig. 78 Diagnosis The most remarkable characteristic refers to the presence of a papilla-like protuberance on the upper-inner corner of the appendage basal cell, which represents the antheridial efferent neck. Etymology The species epithet means “bearing a papilla”, and refers to the prominence on the antheridium. Type material Holotype DENMARK – Nordøstjylland (NEJ) • Fredrikshavn; 57°26.910′ N, 10°32.102′ E; NJ96; on Bledius terebrans (Schiødte, 1866) (Col. Staphylinidae Oxytelinae); Jul.1849; Schiødte Dry0141; Schiødte det.; ZMUC C-F-124208. Isotype DENMARK • same data as for holotype; ZMUC C-F-124209. Description Thallus pale yellowish-amber, slightly darker at the perithecial venter. Basal cell of receptacle (I) obconical, longer than broad. Suprabasal cell of receptacle (II) trapezoidal, as long as broad or slightly longer than broad, separated from cell VI by a strongly oblique septum. Cell III longer than cell II, 1.5 times as long as broad. Primary appendage consisting of several superposed cells and is weakly branched above its suprabasal cell; not exceeding in length the perithecial apex. The basal cell of the primary appendage, which is slightly longer than broad, includes the compound antheridium and several sterile cells. The antheridial cells occupy the area around the upper inner corner of the appendage basal cell, surpassing to some extent the base of the suprabasal cell of the appendage (Fig. 78D–E) and giving rise to a papilla-like prominence which represents the antheridial efferent neck (Fig. 78A–C, arrows). Perithecial stalk cell (VI) very elongated and strongly narrowing towards the base; abruptly constricted just below the perithecial base. Cells m and VII large, inflated, yet protruding outwards, especially cell VII. The separation of these cells from the perithecial ascogenous cavity is well-marked by constrictions. Perithecium pyriform, with a truncate, flat apex. Sometimes a second perithecium may develop from cell II (Fig. 78E–F). Length from foot to apex of perithecium (121–)165–192 µm. Perithecium (including basal cells) (61–)71– 89 × (24–)27–33 µm. Primary appendage (from primary septum to apex, when undamaged) 69–84 µm. Length of perithecial stalk cell (VI) (28–)40–59 µm. Thalli were found on the legs and tarsi of the host. Nothing is known about the collecting circumstances of the host. Remarks Cantharomyces papillatus sp. nov. belongs to the group of species around C. orientalis, but may be readily recognized by several characteristics, e.g., the shape of the antheridium including a papilla (unknown in any other species), the long, very slender and narrowed cell VI, and the enlarged and inflated cells m and VII. Cantharomyces orientalis has been reported on Bledius by Santamaria (2003). Cantharomyces bledii Thaxt. (Thaxter 1890) was described on Bledius from USA, being recorded later from Poland (Siemaszko & Siemaszko 1932); the record of this species from Spain (Santamaria 1989) belongs to C. orientalis. The other species described on Bledius is C. occidentalis Thaxt. (Thaxter 1896) from USA. Both taxa differ from C. papillatus sp. nov. by the above-mentioned characters.Published as part of Santamaria, Sergi & Pedersen, Jan, 2021, Laboulbeniomycetes (Fungi, Ascomycota) of Denmark, pp. 1-425 in European Journal of Taxonomy 781 on pages 320-322, DOI: 10.5852/ejt.2021.781.1583, http://zenodo.org/record/582892
Cryptandromyces cryptophagi Santamaria & Pedersen 2021, sp. nov.
No full textCryptandromyces cryptophagi Santam. sp. nov. MB#840597 Fig. 49D–H Diagnosis Cell I with a dorsal blackish-brown stripe. Cell VII inflated, very large, bigger than cell VI. Etymology The species epithet is based on the host genus Cryptophagus. Type material Holotype DENMARK – Nordøstsjaelland (NEZ) • Stenholtsvang; 55°57.365′ N, 12°21.254′ E; UC30; on Cryptophagus distinguendus Sturm, 1845 (Col. Cryptophagidae); 7 Apr. 2018; JP 1025; JP det.; ZMUC C-F-123532. Isotype DENMARK • same data as holotype; ZMUC C-F-123533, C-F-123534, C-F-123535. Description Thallus hyaline, except for the darkened foot and part of cell I. Basal cell of receptacle (I) obconical, with a pointed hyaline beak at base (Fig. 49E, arrow), about twice longer than broad, dorsally tinged with a dark brown stripe as a prolongation of the foot pigmentation (Fig. 49E, *). Suprabasal cell of receptacle (II) isodiametric to slightly broader than long. Cell III slightly longer than broad, above cell II and separated from it by an oblique septum; sometimes may be subdivided (Fig. 49E, III and III’; Fig. 49F, III). Primary appendage unbranched, consisting of up to eight subequal cells, longer and narrowing towards the apex. Antheridia 1(–3) sessile, simple, bottle-shaped, borne on the inner side of the lower cells of the appendage (Fig. 49G–F, an), appearing deteriorated in mature thalli (Fig. 49E, an). Perithecial stalk cell (VI) trapezoidal, broader than long. Cell VII very large, bigger than cell VI, with a strongly convex outer margin. Perithecium ovoidal, large, reaching half of the length of the thallus. Perithecial tip broad, with the four apical wall cells protruding like lips through a collar-like structure (Fig. 49D, arrows). Trichogyne flexuous (Fig. 49G–H, tr). Length from foot to apex of perithecium 70–79 µm. Perithecium (not including the basal cells) 39–49 × 19–25 µm. Maximum length of primary appendage (from primary septum, when undamaged) 55 µm. Thalli were found on the elytra of the host. The hosts were sifted from mouldy hay with many mice-nests and from moist moss and mouldy spruce needles on sun-exposed forest floor. Remarks This is the first species of the genus described on a beetle belonging to Cryptophagidae. It appears to be morphologically related to some species on Pselaphinae (Col. Staphylinidae) like C. elegans and C. bryaxidis, but may be distinguished from them by the large, protruding cell VII, and the dark brown suffusion that extends along the outer margin of cell I. Antheridium location is similar to the arrangement in C. elegans, but in this species a solitary, stout antheridium is borne by the appendage basal cell, whereas in C. cryptophagi sp. nov. it is found on the suprabasal cell, even in cells above, becoming almost undetectable due to deterioration in the older thalli. Lips protruding through a break near the perithecial apex is a characteristic that has been described for species of Troglomyces. This feature was defined as a collar-like structure or as a scar resulting from some kind of breakdown at the point where the trichogyne was attached, in the perithecial top throughout thallus development (Enghoff & Santamaria 2015).Published as part of Santamaria, Sergi & Pedersen, Jan, 2021, Laboulbeniomycetes (Fungi, Ascomycota) of Denmark, pp. 1-425 in European Journal of Taxonomy 781 on pages 228-229, DOI: 10.5852/ejt.2021.781.1583, http://zenodo.org/record/582892

Description Thallus hyaline, except for the blackened foot and brown appendages. Receptacle axis consisting of (7–)9(–11) superposed cells which are broader than long, those of the basal area being especially flattened, cells gradually elongated towards the distal region. Basal cell of the receptacle (I) longer than broad, tapering towards the foot. Most cells of the receptacle, except the 2–4 lower ones, dividing obliquely at one or both sides into one to more cells to form perithecia, secondary appendages, or antheridia (Fig. 8D, an). These lateral cells remain in contact with cells above and below in such a way that the whole thallus gives the impression of a unilayered sheet. Primary appendage unbranched, entirely dark brown, continuing the main receptacle axis, consisting of rather elongated and apparently rigid cells (this can be verified with the manipulation that we do with a needle to detach the thallus from the host cuticle) (Fig. 8B–E, pa). The uppermost receptacular axis consists of two superposed cells which form a peduncle for the primary appendage (Fig. 8B, *) below the primary septum (Fig. 8B, D, a), and sometimes bear some additional secondary branches which grow upwards parallel to the primary appendage (Fig. 8D, sa). Perithecial stalk cell (VI) inconspicuous, subtriangular (Fig. 8C, VI). Perithecia symmetrical, ovoidal, broadest near the middle height, then gradually tapering towards an indistinct neck and a blunt apex; 1–6 per thallus, unilaterally arranged. Length from foot to apex of uppermost perithecium (86–)100–149(–190) µm. Perithecium (37–)48– 74(–94) × (19–)22–31(–38) µm. Length of primary appendage from primary septum (when undamaged) 158–233 µm. Thalli were found mostly on elytra but also on other body parts of the hosts. Nothing is known about the collecting circumstances of the hosts. Remarks EuphoriomYces enghoffii sp. nov. is similar to E. liodivorus, from which it could easily be distinguished at first sight by the darkish brown appendages, and especially for the primary appendage which, if unbroken, may be very long (up to three times as long as the thallus from foot to uppermost perithecium) (Fig. 8B–E, pa). The thallial appearance may vary substantially according to maturity and position on the host body. Thalli bearing only a single mature perithecium (but with some initials below) could be considered mostly typical (Fig. 8B–C) and have been found on elytra apices. Overmature damaged thalli, with broken appendages, may be difficult to separate from E. liodivorus. Nevertheless, in these circumstances, the brown basis of appendages can help to distinguish them (Fig. 8F, arrows). The precise arrangement of cells explained by Santamaria (2003: 266) for E. liodivorus also applies to E. enghoffii.Published as part of Santamaria, Sergi & Pedersen, Jan, 2021, Laboulbeniomycetes (Fungi, Ascomycota) of Denmark, pp. 1-425 in European Journal of Taxonomy 781 on pages 54-57, DOI: 10.5852/ejt.2021.781.1583, http://zenodo.org/record/582892

Cryptandromyces danicus Santamaria & Pedersen 2021, sp. nov.
No full textCryptandromyces danicus Santam. sp. nov. MB#840598 Fig. 50 Diagnosis Perithecium with a strongly convex margin on one side and straight to concave in the opposite side; the apex with a small rounded protuberance representing a trichogyne stump. Etymology The species epithet is based on Denmark. Type material Holotype DENMARK – Lolland, Falster, Møn (LFM) • Engestofte; 54°45.767′ N, 11°33.506′ E; PF67; on Euconnus wetterhallii (Gyllenhal, 1813) (Col. Staphylinidae Scydmaeninae); 9 May 1952; Johs. Andersen Dry0101; Johs. Andersen det.; ZMUC C-F-124167. Isotype DENMARK • same locality and host as for holotype; 7 Jul. 1950; F. Larsen Dry0100; F. Larsen det.; ZMUC C-F-124166. Description Thallus pale yellowish, shaded in the perithecial venter. Basal cell of receptacle (I) obconical, about twice longer than broad. Suprabasal cell of receptacle (II) pentagonal, broader than long, separated from cells III and VI by oblique septa. Cell III flattened, broader than long, triangular to trapezoidal in section (Fig. 50A). Primary appendage unbranched, rather elongate but not exceeding the perithecial apex in length, consisting of up to seven cells gradually longer upwards, but not narrowing very distinctly. Antheridia unknown. Perithecial stalk cell (VI) two to more times as long as broad, slightly constricted towards the lower middle height. Perithecial wall cell tiers w 1 and w 2 each approximately as long as the three above (w 3-5) all together (Fig. 50E). Perithecium fusiform to ovoidal, with posterior margin (the side with the appendage) straight to concave, and the opposite margin quite convex. Perithecial tip subacute, variably rounded, bearing a rather conspicuous trichogyne stump on the posterior side (Fig. 50G, arrow), which may be seen when in side view as a slight rounded knob (Fig. 50C–D, arrows). Length from foot to apex of perithecium 86–89 µm. Perithecium (not including the basal cells) 50–60 × 19–28 µm. Maximum length of primary appendage (from primary septum, when undamaged) 52 µm. Thalli were found on the elytra of the hosts. Nothing is known about the collecting circumstances of the hosts. Remarks Euconnus wetterhallii is a rarely collected ant-like stone beetle (Col. Staphylinidae Scydmaeninae) which has been reported harbouring Stigmatomyces euconni F.Picard (Picard 1917). A simple observation of the figure published by Picard shows us that neither the appendage with its antheridia nor the perithecia with its spiny protuberance are anything like the fungus we found. The new species reasonably fits in the genus Cryptandromyces. As mentioned in the genus remarks above, ten species (including the new one described here) grow on beetles of Scydmaeninae. Cryptandromyces danicus sp. nov. may be compared with C. geniculatus Thaxt., also reported on Euconnus (as Connophron) from Argentina (Thaxter 1912a) and China (Shen & Ye 2006).Although the two species are similar, the perithecium in C. danicus sp. nov. does not have the strong “geniculate” shape driven by some of the perithecial basal cells (probably cell VII) in C. geniculatus.Published as part of Santamaria, Sergi & Pedersen, Jan, 2021, Laboulbeniomycetes (Fungi, Ascomycota) of Denmark, pp. 1-425 in European Journal of Taxonomy 781 on pages 229-231, DOI: 10.5852/ejt.2021.781.1583, http://zenodo.org/record/582892
