Scutellinia totaranuiensis J. Moravec 1996

Apothecia 2-4(-5) mm diam., gregarious, sessile, rounded, cupulate, then shallowly cupulate to almost discoid, hymenium pale to dark orange-red, outer surface and margin densely covered by very short, dark brown hairs. Hairs short, 60-270(-285) x 12-21.5 µm, light to dark brown, rigid, thick-walled (walls 3-4.5 µm thick), usually 1-3 septate, straight or often curved or flexuous, acuminate above, narrowing towards the base; the base bifurcate to short and narrow roots or usually simple, truncate, or usually attenuated to a subacute end of a similar shape like the upper acute part ("bicuspidate"). Excipulum clearly differentiated: ectal excipulum of textura globulosa-angularis comprising hyaline, large, subglobose to angular cells which are 20-75 µm in diam. and elongated and clavate in the margin of the apothecia; medullary excipulum of textura intricata, comprising interwoven, septate, usually inflated hyphae (6-15 µm in diam.) which grade towards smaller hyphae of the indistinctly differentiated subhymenium. Asci 250-280 x 10-12 µm, cylindrical, rounded above, operculated, attenuated towards the simple base, eight-spored. Ascospores ellipsoid, 13.5-16.5(-17.6) x 7.5- 10.5(-11) µm (excluding the ornamentation and apiculi), usually 16 x 9 µm but also 15 x 10.5 µm, containing several guttules which are of an unequal size, ornamented by large cyanophilic warts and tubercles which measure 1.5-4.5 µm and are mostly rounded, isolated or occasionally mutually attached or connected by thin buckles; on the ascospore poles, the cyanophilic tubercles are usually arranged inside irregular appendages as they are coated by an outermost sheath, forming thus conspicuous apiculi which are up to 10.5 µm high (oil immersion and stained by CB Geigy s. 123 without heating the slides). Paraphyses filiform, 2-3 µm thick, not or slightly enlarged to 3.5-7.5 µm at their tips, containing orange granules.
Apothecia 2-5 mm diam., aggregate, sessilia, orbicularia, primum patellaria, dein subexplanata, hymenio aurantiaco-rubro, marginem et extus pilis brevis, fuscis dense obsita. Pili brevi, 60-270(-285) x 12-21.5 µm, fusci, rigidi, crasse tunicati (parietibus 3-4.5 µm crassis), sparse ( 1-3) septati, recti vel saepe curvati, supra acuti, basi attenuati, breviter bifurcato-radicati vel saepe simplices, truncati vel angustati et saepe subacuti (pili bicuspidati). Excipulum externum e textura globuloso-angulari, parte inferiore (medulla) textura intricata. Asci 250-280 x 10-12 µm, cylindracei, octospori. Ascosporae 13.5-16.5 (-17.6) x 7.5-10.5(-11) µm (ornamento excluso), ellipsoideae, irregulariter multiguttulatae, crasse tuberculoso-verrucosae, ad polis apiculatae. Paraphyses filiformes, 2-3 µm diam., apice non vel sensim (ad 3.5-7.5 µm incrassatae, granulis aurantiacis impletae.
Habitat: Ad terram humidam argillaceo-arenosam viae silvaticae (Metrosideros sp.) in densa societate Pezizae badioconfusae, New Zealand, South Island, Abel Tasman Coastal Track, Totaranui prope Takaka, 6. III. 1993 leg. Jiri Moravec - holotypus in BRNM 599298, isotypi in CUP, WELTU et J.Mor. asservantur.
The new species is well characterized by its small apothecia having the outer surface and the margin densely covered by very short brown hairs, which, especially those in the lower part of the excipulum, are occasionally attenuated towards a subacute base, and thus, they may resemble the hairs in the genus Trichophaeopsis Korf & Erb. The most remarkable feature of the new species are the apiculate ascospores possessing tuberculate ornamentation.
Holotype: New Zealand, South Island, Abel Tasman Coastal Track, Totaranui near Takaka, on moist clayey-sandy soil on a path through a sea-side forest (Metrosideros sp.), closely associated with apothecia of Peziza badioconfusa Korf, 6. III. 1993 leg. Jiri Moravec. (The holotype BRNM 599298, isotypes CUP,WELTU, J.Mor.).
