Armatella apollonigena sp. nov. Hosag. & A. Sabeena (Fig.1; MB No. 805631)
Colonies amphigenous, thin to subdense, up to 3mm in diameter, confluent. Hyphae flexuous
to crooked, branching irregular at acute to wide angles, form loosely and irregularly
reticulated net, cells 35–45 × 5–7 μm. Appressoriaalternate, rarely opposite, straight to variously curved, antrorseto subantrorse, 12–32 μmlong; stalk cells cylindrical, often gibbous, 5–12 μmlong; head cells ovate, oblong, straight to curved, mostly entire but rarely sinuately lobate, 7–20 x
7–12 μm. Peritheciascattered, up to 350µm in diam.; perithecial wall
cells mammiform, up to 17µm long; ascosporesoblong, uniseptate, slightly constricted at the
septum, 32–37 x 12 µm, wall smooth.
Material examined: TBGT 6536 (holotype),
PBL 129 (isotype), 20.ix.2007, on leaves of Apollonias sp. (Lauraceae), Padinharathara, Wayanad,
Kerala, coll. M.C. Riju.
There are 16 species of the genus Armatellaknown to occur on the members of the family Lauraceae.
Of these, Armatella apolloniadis (Biju et al. 2005) is known to occur on this host
genus from the Western Ghats region of Kerala State. However, Armatella apollonigena differs from it in having
unicellular basal cells of the appressoria, entire tosublobate and globose to
oblong head cells in contrast to globose, angular to sublobate ones (Hosagoudar2008). Ascosporesgerminated by producing appressoria from the apical
portion of each cells but with no symptom of collapsing cells.
Etymology: specific epithet based on the host plant genus.
Asterina persigena sp.nov. Hosag.
& B. Divya (Fig. 2; MB No. 805632)
Colonies epiphyllous, dense, spreading, up to
4mm in diameter, confluent. Hyphae
straight to substraight, branching opposite to
irregular at acute to wide angles, loosely reticulate, cells 20–35 x
4–6 µm. Appressoriaalternate to unilateral, unicellular, ovate, oblong, tubular, antrorse to subantrorse,
entire, slightly attenuated at the tip, 12–17 x 5–6 µm. Thyriotheciascattered, orbicular, up to 250 µm in diam., stellatelydehisced at the centre; asci few, globose,
up to 32µm in diam.; ascospores oblong, 1-septate,
constricted at the septum, 28–32 x 10–14 µm, upper cell larger than
the lower, wall smooth.
Materials examined: TBGT 6560 (holotype),
13.xii.2003, on leaves of Persea sp. (Lauraceae), Silent Valley National Park, Palghat, Kerala, coll. V.B. Hosagoudaret al.
Based on the morphology of appressoria, Asterina persigenais similar to Asterina machili Katumoto known on Machilius thumbergius from Japan (Katumoto,
1979) but differs from it in having larger appressoria(12–17 x 5–6 µm vs 9–12 x 3–4
µm) and distinctly larger ascospores (15–18 x
7–8µm vs 28–32 x 14–18 µm).
Etymology: specific epithet based on the host plant genus.
Lembosia hopiigena sp. nov. Hosag.
& A. Sabeena (Fig.
3; MB No. 805633)
Colonies hypophyllous,subdense to dense, crustose,
up to 4mm in diameter, confluent. Hyphae substraight to flexuous, branching opposite to unilateral
at acute to wide angles, loosely reticulate, cells 50–87 ×
4–5 μm. Appressoriaopposite, alternate to unilateral, 1–4 celled, straight to curved,
flexuous to crooked, 17–120 μm long; stalk
cells 1–3 septate, straight, flexuous to
crooked, 2–100 μm long; head cells ovate, globose, entire, angular, sublobateto deeply lobate, 12–27 x 7–20 μm. Thyriothecia scattered, grouped to connate, orbicular at
initial stage but later become elliptic to elongated, longitudinally fissured
at the centre or dissolved at the central portion in case of orbicular ones,
500–900 × 200–600 μm, margin
mostly crenate, rarely fimbriate, fringed hyphae
straight, flexuous to crooked; asci globose, octosporous, up to
50μm in diameter; ascospores brown, conglobate, uniseptate, constricted at the septum, 25–35 ×
15–17 μm, wall slightly echinulate.
Material examined: TBGT
6537, PBL 130 (isotype), 27.vi.2012, on leaves of Hopea sp. (Dipterocarpaceae),
Malabar Botanical Garden, Kozhikode, Kerala, coll. A. Sabeenaet al.
Morenoella anisocarpa Sydow is known on Hopea plagatae from
the Philippines (Sydow & Sydow1914). Since Morenoellais synonymous to Lembosia, Song & Hosagoudar (2003) brought it under the genus Lembosia as L. anisocarpa (Syd.) Hosag. &
Song. However, L. hopiigena differs from it in having
multicellular appressoria.
Etymology: specific epithet based on the host plant genus.
