“…The specimens cited above represent only a few of the over 100 isolates in the collection of the Rancho Santa Ana Botanic Garden, and during recent years we have not routinely isolated the fungus when it has been encountered on substrata collected in southern California. It was most recently described and illustrated by Upadhyay ( 1973) and has been reported and illustrated ( as Helicostylum piriforme ) numerous times in the past ( see under Illustrations).…”

“…8, Notes.-Although Thamnostylum lucknowense was described from India, the several isolates from the United States and Mexico reported here suggest that it is widely distributed. The species was discussed most recently by Upadhyay ( 1973). It grows readily on a variety of media and at temp eratures of 25-30 C forms a dense turf that within 2-3 wk fills the interior of a 2 x 8.5-cm Petri dish.…”

“…is more or less constricted immediately below the primary sporangium, and the sporangiola of species of this genus are always globose to subglobose and nonapophysate. Upadhyay ( 1973 ) transferred H elicostylum repens van Tiegh. ( 1876) to Thamnostylum on the basis of its original, brief, unillustrated description, and we are able to confirm this action from a study of numerous isolates of the fungus.…”

In 1970, von Arx and Upadhyay ( von Arx, 1970) segregated two species of Helicostylum, H. piriforme Bainier ( 1880) and H. lucknowense Rai, Tewari & Mukerji ( 1961 ), into a new genus, Tlwmnostylum von Arx & Upadhyay.…”

Evidence Implicating Thamnostylum lucknowense as an Etiological Agent of Rhino-Orbital Mucormycosis

et al. 2012

e In this report, we present a case of rhino-orbital mucormycosis in a 57-year-old female with poorly controlled diabetes mellitus. The only mold cultured at 25°C, 37°C, and 40°C from a specimen of the nasal crust was identified phenotypically and independently using nuclear ribosomal DNA sequence data as Thamnostylum lucknowense. To our knowledge, this report presents the first data implicating this mucoraceous fungus as a mycotic agent of human infection. CASE REPORTA 57-year-old female patient was admitted to the Emergency Department of the All India Institute of Medical Sciences, New Delhi, India, in February 2009 with complaints of swelling and loss of vision in the right eye over the previous 10 days and right-sided nasal obstruction for the previous week. She had a history of fever, vomiting, and itching in the right eye, with intermittent episodes of altered sensorium. Her current symptoms started with itching followed by loss of vision in the right eye and nasal obstruction and then altered sensorium. She had poorly controlled diabetes mellitus for the previous 8 years and hypertension for 5 years. Her blood pressure was controlled with oral amlodipine at 5 mg daily. There was no history of seizures or trauma.On examination, the patient was disoriented. Her heart rate was 120/min, and blood pressure was 160/70 mm Hg. Ophthalmological examination revealed hyperemia, proptosis, discharge, and sluggish papillary reaction to light in her right eye. Her random blood sugar was 19.7 mmol/liter. She was treated initially with ceftazidime (1 g) every 12 h, vancomycin (500 mg) infusion every 6 h, and subcutaneous injection of human insulin (Actrapid). The patient was transferred to the otorhinolaryngology department for further management.A contrast-enhanced computed tomographic (CT) scan of her brain and orbit showed bilateral polypoidal opacification of the maxillary, sphenoid, and ethmoid sinuses together with involvement of the cavernous sinus. A specimen of the nasal crust was sent to the microbiology laboratory for testing. Direct examination of a portion of the nasal crust in a KOH mount using light microscopy showed hyaline, coenocytic hyphae 4.0 to 7.0 m in diameter. A portion of the nasal crust was cultured on Sabouraud dextrose agar with and without chloramphenicol at 25°C, 37°C, and 40°C in the dark. After 48 h of incubation, only white, cottony colonies producing aerial hyphae were observed on slant cultures at each temperature. No bacterial growth was evident. Over the next 2 to 3 days, the colonies turned from white to olive brown and filled the culture tubes. The in vitro MICs of the following four antifungals were determined by the broth microdilution technique according to the CLSI M38-A2 protocol (7): amphotericin B, 0.5 g/ml; itraconazole, 0.5 g/ml; posaconazole, 0.25 g/ml; and voriconazole, Ͼ64.0 g/ml.Once the diagnosis of acute rhino-orbital mucormycosis was made, the patient was treated with an intravenous infusion of conventional amphotericin B deoxycholate at 50 mg/day. However, the patie...

A total of 1267 microfungi, including 35 Myxomycetes, were recorded from the fecal samples of the 60 horses; of these 395 were found on 20 saddle-horse feces, 363 on 20 race-horses and 509 on 20 working horses. Eighty two species representing 53 genera were recorded; of these 7 were Zygomycetes, 18 Ascomycetes, 1 Basidiomycetes and 25 Fungi Imperfecti: 2 Myxomycetes. Common coprophilous fungi are in decreasing order Pilobolus kleinii, Saccobolus depauperatus, Mucor hiemalis, Lasiobolus ciliatus, Podospora curvula, Petriella guttulata, M. circinelloides, Coprinus radiatus, Dictyostelium mucoroides, Sordaria fimicola, C. miser, C. stercorariusm, Acremonium sp., Coprotus granuliformis, Graphium putredinis, Iodophanus carneus, Chaetomium murorum, Podospora communis, P. inaequalis, P. setosa, Saccobolus versicolor and Cladosporium cucumerinum. Species of Myrothecium verrucaria, Actinomucor elegans, Kernia nitida, Spiculostilbella dendritica and Mucor parvispora were found exclusively in working-horses feces. Badhamia sp., Anixiopsis stercoraria, Echinobotryum state of D. stemonitis, Geotrichum candidum and Oidiodendron sp. were found only in saddle-horses feces. Chlamidomyces palmarum, Philocopra sp. were found exclusively in race-horses feces. Notes on infrequent or interesting fungi include Thamnostylum piriforme, Phialocephala dimorphospora, Rhopalomyces elegans and Spiculostilbella dendritica.
