Andhra Pradesh is the fourth largest state in India by area with dense forests of 44,229km2 and with 397km2 of mangrove forests.  The Srisailam Hill ranges are located in the middle of the state and the Tirumala-Tirupati hills are located in the south (17057′N & 79059′E).  This state represents 5,400 flowering plants and the important forests are protected in four national parks and 22 wildlife sanctuaries. However, such an interesting state with the maximum area of Eastern Ghats is least explored for microfungi excepting the sporadic works on mycorrhizal fungi, rusts, powdery mildews and hyphomycetes.  Hence, we have taken an interest in the systematic study of black mildews in the Pakhal Wildlife Sanctuary, around Pakhal Lake (Pakhal Kothaguda Forest Range in Warangal District and the present work is part of it.)

Sarcinella chloroxyli sp. nov.

Hosag., Moinud., Bagyan. & A. Sabeena

(Image 1, Fig. 1; MycoBank # 805910)

 

Colonies epiphyllous, thin to subdense, up to 2mmin diameter, confluent.  Hyphae flexuous to crooked, branching irregular at acute to wide angles, loosely reticulate, cells 15–27x2–5 μm.  Appressoria alternate to unilateral, ovate, globose, mammiform, broad based, entire, 5–10x5–10 μm; conidiophores micronematous, mononematous, 1–2 septate, 7–10x2–10 μm; conidiogenous cells terminal, monoblastic, cylindrical; conidia blastic, terminal, solitary, sarciniform, 2–5 celled, constricted at the septa, brown to charcoal black, 20–25x25–27 μm, wall smooth.

Material examined: TBGT 6406, 19.x.2012, on leaves of Chloroxylon swieteniaDC. (Flindersiaceae), Kamaram forest, Pakhal Kothaguda Forest Range, Warangal, Eastern Ghats, coll. Md. Khaja Moinuddin.

This is the first report of a schiffnerulaceous fungus on the members of the family Flindersiaceae (Hosagoudar 2003, 2011).

 

Sarcinella gymnosporiae

Subhedar & Rao ex Hosag., Zoos’ Print J. 17: 837, 2002; Hosag., Pl. Pathol. & Quarantine 1: 152, 2011.

Material examined: TBGT 6407, 19.x.2012, on leaves of Maytenus emarginata (Ruiz & Pav.) Loes. [Gymnosporia emarginata (Willd.) Thwaites] (Celastraceae), Kamaram forest, Pakhal Kothaguda Forest Range, Warangal, Eastern Ghats, Md. Khaja Moinuddin.

This fungus is known on this host genus from the Western Ghats region of Maharashtra and is reported here for the first time from the Eastern Ghats.

 

Sarcinella strychni sp. nov.

Hosag., Moinud., Bagyan. & A. Sabeena

(Image 2, Fig. 2; MycoBank # 805911)

 

Colonies hypophyllous, thin, up to 2mm in diameter, confluent.  Hyphae flexuous, branching irregular at acute to wide angles, loosely reticulate, cells 15–20 x 2–5 μm. Appressoria alternate to unilateral, globose, broad based, entire, 5–7 x 5–8 μm.  Conidia of Questieriellastraight to curved, pale brown, 3-septate, mostly scattered in the colonies, 30–37x7–10 μm.  Sarcinella conidiophores produced laterally from the hyphae, single, straight, mononematous, 1–2 septate, 7–20x2–5 μm; conidiogenous cells terminal, monoblastic, integrated, cylindrical.  Sarcinellaconidia blastic, terminal, solitary, ovate to globose, sarciniform, 2–6 celled, slightly constricted at the septa, brown to charcoal black, 20–30x17–27 μm, wall smooth.

Material examined: TBGT 6405, 19.x.2012, on the leaves of Strychnos potatorum L.f. [Strychnos heterodoxa Gilg; Strychnos stuhlmannii Gilg] (Loganiaceae), Kamaram forest, Pakhal Kothaguda Forest Range, Warangal, Eastern Ghats, coll. Md. Khaja Moinuddin.

Questieriella strychni Hosag. is known on this host genus from Karnataka and Kerala states (Hosagoudar 2011) but the present collection differs from it in possessing both Questieriella and Sarcinellastates. Hence, it has been placed in a distinct species.
